Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This non-provisional application claims priority under 35
U.S.C. .sctn.119(a) on Patent Application No(s). 100141904 filed in
Taiwan, R.O.C. on Nov. 16, 2011, the entire contents of which are
hereby incorporated by reference.
BACKGROUND
[0002] 1. Technical Field
[0003] The present disclosure relates to a building with
temperature regulating system and its temperature regulating method
and more particularly to a building with temperature regulating
system and its temperature regulating method which employs forced
convection to reduce temperature.
[0004] 2. Related Art
[0005] Generally, greenhouse is used for providing an ideal
environment for the growth of a large amount of plants. A typical
greenhouse is composed of fencing and top frames, and a covering
body is wrapped around the fencing and the top frames, so that a
closed space is formed inside the greenhouse. A greenhouse with the
aforementioned structure can prevent bugs and mosquitoes from
entering into a plant area of the greenhouse, and an ideal
temperature can be maintained inside the greenhouse. Nevertheless,
being affected by an outdoor temperature and under the sunlight,
the temperature inside the greenhouse will increase, if heat can
not be dissipated appropriately to regulate the temperature, it
will be harmful for the growth of plants due to an increased
temperature inside the greenhouse.
[0006] Therefore, vents or airways are additionally disposed to
regulate the temperature inside the greenhouse, in order to prevent
the temperature inside the greenhouse to get too high and
therefore, to harm the plants inside the greenhouse. This type of
greenhouse with vents includes a first waterproof layer covered on
the greenhouse, at least one vent disposed on the first waterproof
layer, a covering element cooperating with the vent and a second
waterproof layer covered on the covering element. The covering
element has a pivotal pole which is pivotable, and a free pole
rotating between a closed position and an air ventilating position
by using the pivotal pole as its shaft. When the free pole is at
the closed position, the covering element is closely fitted with
the vent, and the second waterproof layer can prevent external air
from entering into the greenhouse through an air permeable layer
from the vent. When the free pole is at the air ventilating
position, a large amount of external air can be entered into the
greenhouse from the vent in order to regulate a temperature inside
the greenhouse.
[0007] The way of disposing additional vents to regulate the
temperature inside the greenhouse mainly utilizes natural
convection to achieve heat exchange between indoor and outdoor
environments of the greenhouse. However, reducing the temperature
timely still cannot be achieved by merely disposing additional
vents. Accordingly, besides the additionally disposed vents, fan
sets can also be disposed in the greenhouse, so that forced
convection generated by the fan sets can reduce the temperature
inside the greenhouse speedily, and therefore, an ideal temperature
regulating effect can be achieved.
[0008] However, when the temperature outside the greenhouse is too
low, and if external air with a low temperature introduced into the
greenhouse by forced convection is blown on the plants inside the
greenhouse directly, the plants may be suffered from chilling
injury or their quality of growth will be affected.
SUMMARY
[0009] According to a temperature regulating method of a building
disclosed by the disclosure, wherein the building comprises a main
construction and a working platform. The main construction has a
bottom surface as well as a first side wall and a second side wall

The first side wall has a first water wall and an air passage
disposed below the first water wall. The second side wall has a
first fan. The working platform is disposed inside the main
construction, and the working platform is higher than the air
passage. Steps of a control method include, providing the building,
and defining an upper temperature limit and a lower temperature
limit; then, determining if the first fan and the air passage have
to be opened according to a temperature inside the main
construction and a temperature outside the main construction in
order to carry out ventilation and temperature reduction.
[0010] According to a building with temperature regulating system
disclosed by the disclosure, the building comprises a main
construction, a working platform, a first water wall, an air
passage and a first fan. The main construction has a bottom surface
as well as a first side wall and a second side wall disposed on two
opposite sides of the bottom surface respectively, the first side
wall has a penetrated air passage. The first water wall is disposed
on the first side wall, and the air passage is disposed below the
first water wall. The working platform is disposed inside the main
construction and it has a supporting surface, a maximum height
between the air passage and the bottom surface is smaller than a
height between the supporting surface and the bottom surface. The
first fan is disposed on the second side wall, and an air generated

[0011] The present invention will become more fully understood by
reference to the following detailed description thereof when read
in conjunction with the attached drawings.

[0012] The present disclosure will become more fully understood
from the detailed description given herein below for illustration

wherein:
[0013] FIG. 1 is a structural illustration of a building with
temperature regulating system according to an embodiment of the
disclosure;
[0014] FIGS. 2 to 6 are illustrations of an operation of a control
method of the building with temperature regulating system according
to an embodiment of the disclosure; and
[0015] FIGS. 7A and 7B are flow charts of the control method of the
building with temperature regulating system according to an
embodiment of the disclosure.
DETAILED DESCRIPTION
[0016] In the following detailed description, for purposes of
explanation, numerous specific details are set forth in order to
provide a thorough understanding of the disclosed embodiments. It
will be apparent, however, that one or more embodiments may be
practiced without these specific details. In other instances,
well-known structures and devices are schematically shown in order
to simplify the drawing.
[0017] Some embodiments of the disclosure provides a building with
temperature regulating system and its temperature regulating method
by which plants inside a greenhouse can be avoided from being
contacted directly with external air with a low temperature, and
the plants can be prevented from suffering of chilling injury.
[0018] FIG. 1 is a structural illustration of a building with
temperature regulating system according to an embodiment of the
disclosure.
[0019] A greenhouse for growing potted plants 20 is used as an
example for a building with temperature regulating system 10 of the
disclosure, but it should not be construed as a limitation to the
disclosure. For instances, the building with temperature regulating
system 10 of this embodiment can also be applied in other
industries such as stock raising.
[0020] The building with temperature regulating system 10 comprises
a main construction 100, a working platform 110, a first water wall
131 and a first fan 141. The main construction 100 can be
constructed with steel frames and canvas, or cement and reinforcing
steel bars, but the disclosure is not limited to them. The main
construction 100 has a bottom surface 103 as well as a first side
wall 101 and a second side wall 102 disposed on two opposite sides
of the bottom surface 103 respectively, and the first side wall 101
has a penetrated air passage 120.
[0021] The working platform 110 of this embodiment is disposed
inside the main construction 100 and is set up on the bottom
surface 103. The working platform 110 is disposed between the first
side wall 101 and the second side wall 102, and the working
platform 110 has a supporting surface 111. A culture bed of
greenhouse is used as an example for the working platform 110, and
therefore the supporting surface 111 of the working platform 110 is
used for placing the potted plants 20 inside the greenhouse.
[0022] Furthermore, the first water wall 131 is disposed on the
first side wall 101, the first water wall 131 can be opened for
ventilation, or with water flowing down while being opened in order
to increase humidity and to reduce the temperature. Because water
wall is a conventional device, related and detailed structures of
the first water wall 131 will not be mentioned herein.
[0023] The air passage 120 in this embodiment penetrates the first
side wall 101, and the air passage 120 is used to connect the space
inside the main construction 100 to the ambient. The air passage
120 can be closed or opened. When the air passage 120 is opened,
external air is capable of entering into the main construction 100
through the air passage 120. Furthermore, the air passage 120 is
disposed below the first water wall 131, and a maximum height D2
between the air passage 120 and the bottom surface 103 is smaller
than a height D1 between the supporting surface 111 and the bottom
surface 103. Due to the height of the air passage 120 relative to
the supporting surface 111, when external cold air is introduced
into the main construction 100 through the air passage 120, the
cold air will not blow on the potted plants 20 on the working
platform 111 directly, and thereby the potted plants 20 can be
prevented from suffering chilling injury.
[0024] Furthermore, the first fan 141 is disposed on the second
side wall 102, and the air generated by the first fan 141 is
corresponding to the working platform 110. More specifically, air
inside the main construction 100 is discharged outside the main
construction 100 by the first fan 141. Furthermore, a height of an
axis of the first fan 141 in this embodiment from the bottom
surface 103 is roughly the same as the height of the supporting
surface 111 from the bottom surface 103, but it should not be
construed as a limitation to the disclosure. The height of the axis
of the first fan 141 from the bottom surface 103 can be adjusted by
any person of average skill in the art according to practical
requirements.
[0025] Referring to FIG. 1, in this embodiment or other
embodiments, the building with temperature regulating system 10 can
further comprise a second water wall 132. The second water wall 132
is disposed on the first side wall 101 between the first water wall
131 and the air passage 120.
[0026] Furthermore, in this embodiment or other embodiments, the
building with temperature regulating system 10 can further comprise
a second fan 142. The second fan 142 is disposed on the second side
wall 102 and is above the first fan 141. The air inside the main
construction 100 is discharged outside the main construction 100 by
the second fan 142.
[0027] Furthermore, in this embodiment or other embodiments, the
building with temperature regulating system 10 can further comprise
a heater 160. The heater 160 is disposed inside the air passage
120, but the disclosure is limited by it. For examples, the heater
160 can be disposed in a path of air passing through the air
passage 120. The heater 160 is used for increasing the temperature
of cold air passing through the air passage 120, and thereby the
potted plants 20 can be prevented from suffering chilling injury
because of the cold air.
[0028] Furthermore, in this embodiment or other embodiments, the
building with temperature regulating system 10 can further comprise
a first temperature sensor 151, a second temperature sensor 152 and
a third temperature sensor 153. The first temperature sensor 151
and the second temperature sensor 152 are disposed on the working
platform 110, and the first temperature sensor 151 is nearer to the
first side wall 101 than the second temperature sensor 152. More
specifically, the first temperature sensor 151 and the second
temperature sensor 152 are disposed on two opposite sides of the
working platform 110 respectively, and the first temperature sensor
151 is nearer to the first side wall 101, while the second
temperature sensor 152 is nearer to the second side wall 102, and
the potted plants 20 are disposed between the first temperature
sensor 151 and the second temperature sensor 152. The first
temperature sensor 151 and the second temperature sensor 152
monitor temperatures at two opposite ends of the potted plants 20
respectively. More specifically, temperatures of all the areas
inside the main construction 100 are different, and therefore by
disposing the first temperature sensor 151 and the second
temperature sensor 152, changes of a temperature gradient between
the first temperature sensor 151 and the second temperature sensor
152 can be monitored precisely.
[0029] The positions of the first temperature sensor 151 and the
second temperature sensor 152 are not fixed, and the positions of
the first temperature sensor 151 and the second temperature sensor
152 can be adjusted according to positions of areas for placing the
potted plants 20, provided that the potted plants 20 are disposed
between the first temperature sensor 151 and the second temperature
sensor 152, and the first temperature sensor 151 is nearer to the
first side wall 101 than the second temperature sensor 152.
[0030] Furthermore, the third temperature sensor 153 is disposed
outside the main construction 100 for detecting the temperature
outside the main construction 100.
[0031] Referring to FIGS. 2 to 6 and cooperating with FIGS. 7A and
7B at the same time, FIGS. 2 to 6 are illustrations of an operation
of a control method of a building with temperature regulating
system according to an embodiment of the disclosure. FIGS. 7A and
7B are flow charts of a control method of a building with
temperature regulating system according to an embodiment of the
disclosure.
[0032] The control method of the building with temperature
regulating system 10 includes following steps.
[0033] Referring to FIGS. 2 and 7A, firstly, the potted plants 20
between the first temperature sensor 151 and the second temperature
sensor 152 are disposed in the building with temperature regulating
system 10, and an upper temperature limit and a lower temperature
limit (S1) are limited. For this embodiment, the range between the
upper temperature limit and the lower temperature limit can be
ambient temperatures for an optimum growing condition of the potted
plants 20. For example, the upper temperature limit rates be
30.degree. C. and the lower temperature limit can be 24.degree.
C.
[0034] Then, if the temperature detected by the first temperature
sensor 151 or the second temperature sensor 152 is higher than or
equal to the upper temperature limit (S2) is determined. If the
temperature detected by the first temperature sensor 151 or the
second temperature sensor 152 is higher than or equal to the upper
temperature limit, whether an outdoor temperature outside the main
construction 100 is lower than the lower temperature limit by the
third temperature sensor 153 (S3) is detected. If the outdoor
temperature detected by the third temperature sensor 153 is lower
than the lower temperature limit, the first fan 141 is turned on
and the air passage 120 is opened to carry out ventilation and
temperature reduction (S4).
[0035] More specific on the abovementioned control steps, wherein
the temperature detected by the first temperature sensor 151 or the
second temperature sensor 152 is used as a reference for
determining a main temperature inside the main construction 100.
Therefore, when a temperature detected by the first temperature
sensor 151 or the second temperature sensor 152 is higher or equal
to the upper temperature limit (30.degree. C.), it represents that
the temperature inside the main construction 100 has reached or
over a highest temperature for the optimum growing condition of the
potted plants 20. At this point, an external air must be introduced
into the main construction 100 to reduce the temperature inside the
main construction 100. Before introducing the external air,
information on a temperature of the external air is acquired by
using the third temperature sensor 153. For example, when the
temperature (e.g. an outdoor temperature in winter is 15.degree.
C.) outside the main construction 100 detected by the third
temperature sensor 153 is lower than the lower temperature limit
(24.degree. C.), it represents that the outdoor air is too cold. At
this point, the first fan 141 is turned on and the air passage 120
is opened to carry out ventilation and temperature reduction as
shown in FIG. 2. When the external cold air enters the main
construction 100 through the air passage 120, an air formed by the
external cold air passes through below the working platform 110,
and then it is discharged outside the main construction 100 by the
first fan 141. Thereby, the temperature inside the main
construction 100 is reduced by the external cold air, and the
potted plants 20 are not in the direct path of the air of the
external cold air. Therefore, the problem of growing quality of the
potted plants 20 being affected by cold air can be prevented.
[0036] Then, it is determined that if a temperature detected by the
first temperature sensor 151 is lower than the lower temperature
limit (S5). If it is lower, the rotating speed of the first fan 141
is reduced or the heater 160 is turned on (S6). If it is not lower,
no change is made, and the temperature with the first temperature
sensor 151 is monitored continuously. More specifically, if the
temperature detected by the first temperature sensor 151 is lower
than the lower temperature limit (24.degree. C.), it represents
that the flow rate of the air of the cold air is too high or the
temperature is too low, and the temperature at the end of the
working platform 110 closed to the first side wall 101 is too low.
Thus the potted plants 20 on the working platform 110 closed to the
first side wall 101 may suffer from chilling injury. Therefore,
once a temperature detected by the first temperature sensor 151 is
lower than the lower temperature limit (24.degree. C.), the
rotating speed of the first fan 141 is reduced immediately, so that
the flow rate of the air of the external cold air is reduced in
order to increase the temperature at the end of the working
platform 110 closed to the first side wall 101. Or, by turning on
the heater 160 to increase the temperature of the air of the cold
air, the potted plants 20 can be prevented from suffering chilling
injury or their quality of growth can be prevented from being
affected.
[0037] Referring to FIGS. 3, 4, 7A and 7B, after detecting if an
outdoor temperature outside the main construction 100 is lower than
the lower temperature limit by the third temperature sensor 153
(S3), if the outdoor temperature outside the main construction 100
detected by the third temperature sensor 153 is higher than or
equal to the lower temperature limit (24.degree. C.), it is further
determined that if the outdoor temperature outside the main
construction 100 detected by the third temperature sensor 153 is
lower than the upper temperature limit (S7). If the outdoor
temperature outside the main construction 100 is lower than the
upper temperature limit, the air passage 120 is closed, the second
fan 142 is turned on and the first water wall 131 is opened to
carry out ventilation and temperature reduction (S8). For example,
if the outdoor temperature (e.g. an outdoor temperature in spring
and autumn is 25 to 27.degree. C.) outside the main construction
100 detected by the third temperature sensor 153 is higher than or
equal to the lower temperature limit (24.degree. C.), and lower
than the upper temperature limit (30.degree. C.), it represents
that the outdoor temperature is a suitable ambient temperature for
the growing of the potted plants 20. At this point, the air passage
120 is closed, the second fan 142 is turned on and the first water
wall 131 is opened, so that the external air enters the main
construction 100 through the first water wall 131 directly to
reduce the temperature, and it is discharged outside the main
construction 100 by the second fan 142 as shown in FIG. 3.
[0038] Furthermore, after the ventilation and temperature reduction
are carried out by the second fan 142 and the first water wall 131
for a time interval, it is determined that if a temperature
detected by the second temperature sensor 152 is still higher than
or equal to the upper temperature limit (S9). If the temperature
detected by the second temperature sensor 152 is lower than the
upper temperature limit, keep monitoring the temperature by the
second temperature sensor 152 and maintaining a fixed rotating
speed of the fan. If the temperature detected by the second
temperature sensor 152 is higher than or equal to the upper
temperature limit, then the rotating speed of the fan is increased
and it is determined that if the temperature detected by the second
temperature sensor 152 is lower than the upper temperature limit.
When the rotating speed of the fan is adjusted to the highest
gradually and if the temperature detected by the second temperature
sensor 152 is still higher than or equal to the upper temperature
limit, then the second water wall 132 is opened (S10). More
specifically, if the ventilation and temperature reduction are
carried out by the second fan 142 and the first water wall 131 for
a time interval, for example, five minutes, ten minutes or fifteen
minutes, and when the rotating speed of the fan is adjusted to the
highest, and if the temperature detected by the second temperature
sensor 152 is still higher than or equal to the upper temperature
limit, it represents that effects of ventilation and temperature
reduction are not ideal. Therefore, the second water wall 132 can
be further opened to increase the flow rate of the external air
entering into the main construction 100 in order to enhance the
effects of ventilation and temperature reduction as shown in FIG.
4.
[0039] Referring to FIGS. 5, 6, 7A and 7B, after the step of
detecting if an outdoor temperature outside the main construction
100 is lower than the lower temperature limit by the third
temperature sensor 153 (S3), if the outdoor temperature outside the
main construction 100 detected by the third temperature sensor 153
is higher than or equal to the lower temperature limit (24.degree.
C.), then it is further determined that if the outdoor temperature
outside the main construction 100 detected by the third temperature
sensor 153 is lower than the upper temperature limit (S7). If the
outdoor temperature outside the main construction 100 is higher
than or equal to the upper temperature limit, the second fan 142 is
turned on and the first water wall 131 is opened, and water flows
down on the first water wall 131 to carry out ventilation and
temperature reduction (S11). For example, if the outdoor
temperature (e.g. an outdoor temperature in summer is 32.degree.
C.) outside the main construction 100 detected by the third
temperature sensor 153 is higher than or equal to the upper
temperature limit (30.degree. C.), it represents that the outdoor
temperature is over an upper ambient temperature limit suitable for
the growing of the potted plants 20. At this point, an effect of
temperature reduction still can not be achieved even if the
external air is introduced inside the main construction 100
directly. Therefore, the second fan 142 is turned on and the first
water wall 131 is opened, and water flows down on the first water
wall 131 to carry out ventilation and temperature reduction at the
same time. Water is discharged and flows down from a water supply
device on the first water wall 131, so that the water current is
flowed down along the first water wall 131 and therefore, the first
water wall 131 is moistened. The water flowing down on the first
water wall 131 can be recycled to be used repeatedly. Therefore,
when the external air passes through a through hole on the
moistened first water wall 131, a large amount of heat is absorbed
by evaporation of the water, so that a temperature of the air
passing through the first water wall 131 can be reduced. After the
step of letting water to flow down on the first water wall 131, the
temperature of the external air is reduced first before entering
the main construction 100 to be further cooled, and is discharged
outside the main construction 100 by the second fan 142 as shown in
FIG. 5.
[0040] Furthermore, after the ventilation and temperature reduction
are carried out by the second fan 142 and the first water wall 131
for a time interval, it is determined that if a temperature
detected by the second temperature sensor 152 is still higher than
or equal to the upper temperature limit (S12). If the temperature
detected by the second temperature sensor 152 is lower than the
upper temperature limit, then the second temperature sensor 152
continuously monitor the temperature and the fan maintains a fixed
rotating speed. If the temperature detected by the second
temperature sensor 152 is still higher than or equal to the upper
temperature limit, then the rotating speed of the fan is increased
and it is determined that if the temperature detected by the second
temperature sensor 152 is lower than the upper temperature limit.
When the rotating speed of the fan is adjusted to the highest
gradually and if the temperature detected by the second temperature
sensor 152 is still higher than or equal to the upper temperature
limit, then the second water wall 132 is opened and water flows
down on the second water wall 132 (S13). More specifically, if the
ventilation and temperature reduction are carried out by the second
fan 142 and water flows on the first water wall 131 for a time
interval, for example, five minutes, ten minutes or fifteen
minutes, and when the rotating speed of the fan is adjusted to the
highest, and if the temperature detected by the second temperature
sensor 152 is still higher than or equal to the upper temperature
limit, it represents that effects of ventilation and temperature
reduction are not ideal. Therefore, the second water wall 132 can
be further opened and water can flows down on the second water wall
132 to increase a flow rate of the external air entering into the
main construction 100 in order to enhance the effects of
ventilation and temperature reduction as shown in FIG. 6.
[0041] According to the temperature regulating method of the
building of the above-mentioned embodiment, by having a maximum
height between the air passage and the bottom surface smaller than
a height between the supporting surface of the working platform and
the bottom surface, when the external cold air is introduced into
the building through the air passage, the cold air will not blow
the potted plants on the working platform directly, and thereby the
potted plants can be prevented from suffering chilling injury or
their quality of growth can be prevented from being affected.
Furthermore, by using the control method of the embodiment,
different steps of ventilation and temperature reduction can be
carried out for the building with temperature regulating system
according to different external temperatures in spring, summer,
autumn and winter, in order to ensure that the temperature inside
the building can be maintained within an ideal range of controlled
temperatures.
[0042] Note that the specifications relating to the above
embodiments should be construed as exemplary rather than as
limitative of the present invention, with many variations and
modifications being readily attainable by a person of average skill
in the art without departing from the spirit or scope thereof as
defined by the appended claims and their legal equivalents.
