Description
TECHNICAL FIELD OF THE DISCLOSURE
[0001] The disclosure relates to the field of dehumidifier control,
and in particular to a refrigerant control method and apparatus for
a dehumidifier.
BACKGROUND OF THE DISCLOSURE
[0002] All conventional technical solutions for reporting
refrigerant shortage are aimed at air conditioners instead of
dehumidifiers, and the air conditioners and the dehumidifiers are
greatly different in system running mode and structural
arrangement. For example, a fluorine shortage control method for a
cooling/heating cabinet machine of a certain company may be set as
follows. Firstly, a temperature difference between an inner tube
temperature and an inner loop temperature during starting is
judged, wherein it is guaranteed that an air conditioner is
normally started. Secondly, different fluorine shortage
determination parameter ranges are determined by means of the inner
loop temperature and an outer tube temperature. Thirdly, a
difference between the inner tube temperature or the outer tube
temperature and an environment temperature is continuously detected
after the air conditioner has been started for a period of time,
and if the difference reaches a certain difference range, a
fluorine shortage fault is reported. Since heat exchangers of the
dehumidifiers are located indoors and only evaporators are provided
with temperature sensing bulbs, the technical solutions for
reporting refrigerant shortage, applicable to the air conditioners,
are not applicable to the dehumidifiers.
[0003] The dehumidifiers on the current market cannot intelligently
recognize the leakage of a system refrigerant and cannot report a
refrigerant leakage fault in time, thereby causing a potential
safety hazard.
[0004] An effective solution has not been proposed for the problems
currently.

range, the starting time is continuously recorded.
[0011] Furthermore, after it is judged whether the dehumidifier has
the refrigerant fault according to the refrigerant leakage amount,
the method may further include that: under the condition that the
dehumidifier does not have the refrigerant fault, a controller does
not report the refrigerant fault and controls the dehumidifier to
continuously run; and under the condition that the dehumidifier has
the refrigerant fault, the controller gives a refrigerant fault
alarm, and/or the controller controls the dehumidifier to stop.

[0023] It is important to note that the description and claims of
the disclosure and terms "first", "second" and the like in the

instead.
[0024] According to an embodiment of the disclosure, a refrigerant
control apparatus for a dehumidifier is provided. As shown in FIG.
1, the apparatus may include: a first temperature detection module
10, configured to detect an environment temperature and an
evaporator tube temperature of a dehumidifier; a data obtaining
module 30, configured to obtain a refrigerant leakage amount of the
dehumidifier according to the environment temperature and the
evaporator tube temperature; and a fault obtaining module 50,
configured to judge whether the dehumidifier has a refrigerant
fault according to the refrigerant leakage amount.
[0025] By means of the disclosure, the first temperature detection
module detects the environment temperature and the evaporator tube
temperature of the dehumidifier, and the data obtaining module and
the fault obtaining module judge whether the dehumidifier has the
refrigerant fault according to the environment temperature and the
evaporator tube temperature, so that the effect of intelligently
recognizing the refrigerant fault of the dehumidifier is achieved,
and it can be determined whether it is necessary to report a
refrigerant fault parameter of a refrigerant leakage fault
according to the recognized refrigerant leakage amount, thereby
solving the technical problems in the conventional art that the
dehumidifier cannot intelligently recognize the leakage of a system
refrigerant and cannot report the refrigerant leakage fault in time
so as to cause the potential safety hazard. The effects of
intelligently recognizing the refrigerant leakage amount of the
dehumidifier and reporting the refrigerant fault in time are
achieved, a series of reliability faults and potential safety
hazards probably caused to a product during the shortage of the
system refrigerant are effectively reduced, and the reliability and
safety of the product are improved. The functions of the product
are optimized, so that the product is more humanized and can be
used more safely and reliably.
[0026] In the embodiment of the disclosure, the data obtaining
module 30 includes: a calculation module, configured to calculate a
difference between the environment temperature and the evaporator
tube temperature; and an obtaining sub-module, configured to obtain
the refrigerant leakage amount corresponding to the difference.
[0027] Furthermore, the fault obtaining module 70 may include: a
reading module, configured to read a dehumidification ability
parameter of the dehumidifier, corresponding to the refrigerant
leakage amount, from a pre-set database; a dehumidification
detection module, configured to detect whether the dehumidification
ability parameter within a pre-set dehumidification ability range;
and a first fault obtaining sub-module, configured to determine
that the refrigerant of the dehumidifier is faulty under the
condition that the dehumidification ability parameter does not
within the pre-set dehumidification ability range.
[0028] Wherein, the dehumidification ability parameter may be a
parameter representative of a dehumidification ability of the
dehumidifier by percentage.
[0029] In the embodiment of the disclosure, the apparatus may
further include: a collection module, configured to collect an
exhaust temperature of the dehumidifier under the condition that
the dehumidification ability parameter within the pre-set
dehumidification ability range; a second temperature detection
module, configured to detect whether the exhaust temperature within
a pre-set temperature range; a second fault obtaining sub-module,
configured to determine that the refrigerant of the dehumidifier is
faulty under the condition that the exhaust temperature does not
within the pre-set temperature range; and a third fault obtaining
sub-module, configured to determine that the refrigerant of the
dehumidifier is normal under the condition that the exhaust
temperature within the pre-set temperature range. In the
embodiment, the pre-set temperature range refers to an exhaust
temperature capable of ensuring that the dehumidifier works
normally, and the pre-set temperature range may be greater than 110
DEG C.
[0030] Wherein, the pre-set dehumidification ability range in the
embodiment may be 0-70%. When the refrigerant allowance of the
dehumidifier is less than 70%, the exhaust temperature of a system
rises highly (the temperature exceeds an allowed running range of
the specification of a compressor and reaches 110 DEG C under
relatively-severe working conditions. At this time, the
dehumidification amount is low, and the compressor is prone to
frequent overload protection, thereby even causing the potential
safety hazard.
[0031] Furthermore, the refrigerant control apparatus may further
include: a continuous running module, configured to control the
dehumidifier to continuously run by a controller without reporting
of the refrigerant fault under the condition that the dehumidifier
does not have the refrigerant fault; and an alarming and stopping
module, configured to give a refrigerant fault alarm by the
controller and/or control the dehumidifier to stop by the
controller under the condition that the dehumidifier has the
refrigerant fault.
[0032] Specifically, Table 1 shows a corresponding relationship
among the difference, the refrigerant leakage amount and the
dehumidification ability parameter.
[0033] More specifically, Table 1 shows different refrigerant
leakage amounts corresponding to the difference range between the
environment temperature and the evaporator tube temperature,
different temperature differences correspond to different residual
refrigerant amounts, and the controller judges whether it is
necessary to report the refrigerant leakage fault according to the
refrigerant leakage amount. Specifically, the continuous running
module does not report any faults in case of non-obvious influence
on the dehumidification ability of the system (namely, any faults
are not reported in case of conformation to the pre-set
dehumidification ability range in the embodiment so as to ensure a
minimum refrigerant amount of over 70% of a dehumidification amount
under rated working conditions of the dehumidifier); and under the
condition that the dehumidification ability of the system is
greatly reduced or the exhaust temperature of the compressor is
over-high so as to exceed an allowed maximum compressor running
exhaust temperature value of the specification of the compressor,
the alarming and stopping module reports the refrigerant leakage
fault in time and performs stop protection in the presence of the
potential safety hazard (namely under the condition that the
dehumidifier has the refrigerant fault in the embodiment).

[0034] Specifically, the first temperature detection module 10 may
include: a first recording module, configured to start a timer
after the dehumidifier is started and record starting time of the
dehumidifier; a time detection module, configured to detect whether
the starting time within a pre-set time range; a third temperature
detection module, configured to detect the environment temperature
and the evaporator tube temperature of the dehumidifier under the
condition that the starting time within the pre-set time range; and
a second recording module, configured to continuously record the
starting time under the condition that the starting time does not
within the pre-set time range.
[0035] In the embodiment of the disclosure, the pre-set time range
may be 8 or 9 minutes.
[0036] In the embodiment of the disclosure, the dehumidifier
monitors a system refrigerant amount in real time, intelligently
recognizes whether the system refrigerant leaks, and calculates and
obtains a system refrigerant leakage amount when recognizing that
the system refrigerant leaks (in the embodiment of the disclosure,
the refrigerant leakage mount corresponding to the difference can
be read from the pre-set database).
[0037] According to an embodiment of the disclosure, a refrigerant
control method for a dehumidifier is provided. As shown in FIG. 2,
the method may include the steps as follows.
[0038] Step S102: An environment temperature and an evaporator tube
temperature of a dehumidifier are detected.
[0039] Step S104: According to the environment temperature and the
evaporator tube temperature, a refrigerant leakage amount of the
dehumidifier is obtained.
[0040] Step S106: According to the refrigerant leakage amount, it
is judged whether the dehumidifier has a refrigerant fault.
[0041] By means of the disclosure, a first temperature detection
module detects the environment temperature and the evaporator tube
temperature of the dehumidifier, and a data obtaining module and a
fault obtaining module judge whether the dehumidifier has the
refrigerant fault according to the environment temperature and the
evaporator tube temperature, so that the effect of intelligently
recognizing the refrigerant fault of the dehumidifier is achieved,
and it can be determined whether it is necessary to report a
refrigerant fault parameter of a refrigerant leakage fault
according to the recognized refrigerant leakage amount, thereby
solving the technical problems in the conventional art that the
dehumidifier cannot intelligently recognize the leakage of a system
refrigerant and cannot report the refrigerant leakage fault in time
so as to cause the potential safety hazard. The effects of
intelligently recognizing the refrigerant leakage amount of the
dehumidifier and reporting the refrigerant fault in time are
achieved, a series of reliability faults and potential safety
hazards probably caused to a product during the shortage of the
system refrigerant are effectively reduced, and the reliability and
safety of the product are improved. The functions of the product
are optimized, so that the product is more humanized and can be
used more safely and reliably.
[0042] Wherein, in the step that the environment temperature and
the evaporator tube temperature of the dehumidifier in the
embodiment, the temperatures can be collected and detected via a
temperature sensor.
[0043] In the embodiment of the disclosure, the step that the
refrigerant leakage amount of the dehumidifier is obtained
according to the environment temperature and the evaporator tube
temperature includes that: a difference between the environment
temperature and the evaporator tube temperature is calculated; and
the refrigerant leakage amount corresponding to the difference is
obtained.
[0044] Specifically, the step that a refrigerant fault parameter of
the dehumidifier is obtained according to the refrigerant leakage
amount may include that: a dehumidification ability parameter of
the dehumidifier, corresponding to the refrigerant leakage amount,
is read from a pre-set database; it is detected whether the
dehumidification ability parameter within a pre-set
dehumidification ability range; and under the condition that the
dehumidification ability parameter does not within the pre-set
dehumidification ability range, it is determined that the
refrigerant of the dehumidifier is faulty.
[0045] Wherein, the dehumidification ability parameter may be a
parameter representative of a dehumidification ability of the
dehumidifier by percentage.
[0046] According to the embodiment of the disclosure, after it is
detected whether the dehumidification ability parameter within the
pre-set dehumidification ability range, the method may further
include that: under the condition that the dehumidification ability
parameter within the pre-set dehumidification ability range, an
exhaust temperature of the dehumidifier is collected; it is
detected whether the exhaust temperature within a pre-set
temperature range; under the condition that the exhaust temperature
does not within the pre-set temperature range, it is determined
that the refrigerant of the dehumidifier is faulty; and under the
condition that the exhaust temperature within the pre-set
temperature range, it is determined that the refrigerant of the
dehumidifier is normal.
[0047] Furthermore, the step that the environment temperature and
the evaporator tube temperature of the dehumidifier are detected
includes that: after the dehumidifier is started, a timer is
started, and starting time of the dehumidifier is recorded; it is
detected whether the starting time within a pre-set time range;
under the condition that the starting time within the pre-set time
range, the environment temperature and the evaporator tube
temperature of the dehumidifier are detected; and under the
condition that the starting time does not within the pre-set time
range, the starting time is continuously recorded.
[0048] In the embodiment of the disclosure, after it is judged
whether the dehumidifier has the refrigerant fault according to the
refrigerant leakage amount, the method may further include that:
under the condition that the dehumidifier does not have the
refrigerant fault, a controller does not report the refrigerant
fault and controls the dehumidifier to continuously run; and under
the condition that the dehumidifier has the refrigerant fault, the
controller gives a refrigerant fault alarm, and/or the controller
controls the dehumidifier to stop.
[0049] Specifically, an implementation mode that the controller
judges whether it is necessary to report the refrigerant leakage
fault according to the recognized refrigerant leakage amount is as
follows. After recognizing the shortage of the system refrigerant
(the refrigerant leakage amount of the dehumidifier is greater than
a pre-set value), the dehumidifier calculates and obtains the
dehumidification ability of the dehumidifier (namely the
dehumidification ability parameter in the embodiment), and monitors
the exhaust temperature of a compressor. If the dehumidification
ability and the exhaust temperature of the compressor are both
within a normal value range (it is ensured that the
dehumidification amount of the dehumidifier is greater than 70%
under rated working conditions and the exhaust temperature is lower
than an allowed maximum compressor running exhaust temperature
value of the specification of the compressor), the controller does
not report any faults, and the dehumidifier continuously runs; and
if the dehumidification ability is greatly reduced (the
dehumidification amount of the dehumidifier is less than 70% under
the rated working conditions) or the exhaust temperature of the
compressor is over-high, the controller reports the refrigerant
leakage fault and performs stop protection.
[0050] It is important to note that in order to simply describe
each of the method embodiments, the embodiment is expressed as a
series of motion combinations. However, those skilled in the art

[0051] By means of the descriptions of the implementation mode,

to the embodiment can be realized by means of software and a
necessary general hardware platform. Certainly, the method can also
be realized by means of hardware. However, the former is a better

[0052] From the embodiments of the disclosure, it can be known that
the disclosure achieves the following technical effects that: the
dehumidifier intelligently recognizes the refrigerant leakage
amount after the system refrigerant leaks; the controller judges
whether it is necessary to report the refrigerant leakage fault
according to the recognized refrigerant leakage amount; and any
faults are not reported in case of non-obvious influence on the
dehumidification ability of the system, and the refrigerant leakage
fault is reported in time when the dehumidification ability of the
system is greatly reduced or the exhaust temperature of the
compressor is over-high so as to cause the potential safety
hazard.
