Description
BACKGROUND OF THE INVENTION
[0001] 1. Field of the Invention
[0002] The present invention relates to a solar energy
air-conditioning system, and more particularly to an automobile
air-conditioning system operated by a hybrid motive power while the
automobile is being driven.
[0003] 2. Description of Prior Art
[0004] Due to the effects of global warming, fuel shortage and oil
price, many products and automobiles capable of saving energy and
protecting environments are developed and introduced to the market.
The recent hottest topical subject is about hybrid automobiles that
combine a gasoline or diesel engine with an electric engine and
reduce fuel consumption and waste gas, and these hybrid automobiles
are praised and welcome by consumers.
[0005] A hybrid automobile concurrently has an engine, an electric
motor, and a cell to assist automobile driving. If the speed of an
automobile is slow, then an automobile control system of the
automobile will automatically switch the motive power to a cell for
driving the motor, and then the motor will drive the automobile. If
the speed of the automobile is fast, then the automobile control
system will switch the motive power to the engine for driving the
automobile, and thus achieving the effects of reducing the gas
consumption and waste gas exhaustion. However, the selling price of
hybrid automobiles is high and unaffordable to consumers yet.
[0006] Further, the issue of gas consumption is not totally a
result of driving an automobile by an engine, because a driver may
start the automobile air-conditioning system while driving the
automobile, and the automobile air-conditioning system produces
cool air to be entered into the automobile, so that the driver can
drive the automobile in a comfortable manner. However, the
automobile air-conditioning system has significant effects on
increasing the gas consumption and reducing the loss of motive
power of the engine. After the automobile air-conditioning system
is started, an electromagnetic clutch in a mechanical compressor of
the air-conditioning system is operated, such that a belt pulley of
the mechanical compressor is driven by a transmission belt of the
engine to rotate a rotor of the mechanical compressor and compress
the Freon to flow, and the cool air produced by the automobile
air-conditioning system is entered into the automobile, and thus
increasing the gas consumption and reducing the loss of motive
power of the engine.
[0007] However, the well-developed hybrid technology of combining
fuel and electric energy as the motive power for an automobile
air-conditioning system can be applied, such that the hybrid power
can be used for driving the operation of an automobile
air-conditioning system while an automobile is being driven, so as
to reduce the gas consumption and the loss of motive power of the
engine.
SUMMARY OF THE INVENTION
[0008] In view of the foregoing shortcomings of the prior art, the
inventor of the present invention based on years of experience in
the related industry to conduct experiments and modifications, and
finally designed a feasible solution to overcome the shortcomings
of the prior art.
[0009] Therefore, the present invention is to provide an automobile
air-conditioning system operated by a hybrid power while the
automobile is being driven, so as to reduce the gas consumption and
the loss of motive power of the engine while the automobile is
moving and the automobile air-conditioning system is operating.
[0010] The solar energy air-conditioning auxiliary system in
accordance with the present invention comprises:
[0011] a solar power supply, for converting a light into an
electric energy output;
[0012] a voltage detector, electrically coupled to the solar power
supply, for detecting a voltage of the solar power supply;
[0013] a motor, electrically coupled to the solar power supply, and
driven by the voltage outputted by the solar power supply;
[0014] a motive power allocation unit, electrically coupled to the
voltage detector, the motor, the engine and the electromagnetic
clutch, for allocating a motive power with the proportion of an
motor output and an engine output; and
[0015] an automobile air-conditioning system, comprising: an
electromagnetic clutch and a mechanical compressor coupled to the
electromagnetic clutch, and the electromagnetic clutch being
electrically coupled to the motive power allocation unit;
[0016] wherein the motive power allocation unit can allocate a
motive power with a smaller percentage of motor output and a larger
percentage of engine output to start the operation of the
automobile air-conditioning system, after the motive power
allocation unit receives a signal detected by the voltage detector
and the voltage of a cell is determined to be sufficient. The
automobile air-conditioning system is started and operated
completely by the motive power outputted by the engine, if it
indicates that the cell has insufficient power after the voltage
detector detects a computed signal of the motive power allocation
unit.
BRIEF DESCRIPTION OF DRAWINGS
[0017] FIG. 1 is a schematic circuit block diagram of an automobile
solar energy air-conditioning auxiliary system in accordance with
the present invention.
DETAILED DESCRIPTION OF THE INVENTION
[0018] The technical characteristics, features and advantages of
the present invention will become apparent in the following
detailed description of the preferred embodiments with reference to
the accompanying drawings. However, the drawings are provided for
reference and illustration only and are not intended for limiting
the scope of the invention.
[0019] Referring to FIG. 1 for a schematic circuit diagram of a
solar energy air-conditioning auxiliary system, the solar energy
air-conditioning auxiliary system comprises: a solar power supply
1, a voltage detector 2, a motor 3, a motive power allocation unit
4, an automobile air-conditioning system 5 and an engine 6. A
hybrid motive power is used for starting the operation of the
automobile air-conditioning system 5 while the automobile is being
driven, so as to reduce the gas consumption and the loss of motive
power of the engine 6.
[0020] The solar power supply 1 comprises: a solar panel 11, an
electric charger 12, a cell 13, and an electric power converter 14.
The electric charger 12 is electrically coupled to the solar panel
11 and the cell 13, and the electric power converter 14 is
electrically coupled to the cell 13. The sunlight absorbed by the
solar panel 11 is converted into electric energy which is
transmitted to the electric charger 12, and the electric charger 12
charges the cell 13. The voltage is stored in the cell 13, such
that when the voltage is outputted from the cell 13, the electric
power converter 14 converts the voltage into an electric power for
driving the motor 3 to operate. The solar panel 11 and electric
charger 12 as shown in FIG. 1 are prior arts, and thus will not be
described here. In this embodiment, the cell 13 is a battery and
the electric power converter 14 is a transformer.
[0021] The voltage detector 2 is electrically coupled to the cell
13 for detecting the electric capacity of the cell 13, and the
detected signal is transmitted to the motive power allocation unit
4 for the computation.
[0022] The motor 3 is electrically coupled to the electric power
converter 14 and driven to operate by the electric power outputted
by the electric power converter 14.
[0023] The motive power allocation unit 4 is a microprocessor
electrically coupled to the voltage detector 2, the motor 3 and the
engine 6 for allocating the proportion of motive power outputted by
the motor 3 and the engine 6, such that if the voltage of the cell
13 is determined to be sufficient after the motive power allocation
unit 4 receives a computed signal detected by the voltage detector
2, the motive power allocation unit 4 can allocate the motive power
with a relative proportion of a lower percentage (such as 30%) of
motive power outputted by the motor 3 and a higher percentage (such
as 70%) of the motive power outputted by the engine 6 to start the
automobile air-conditioning system 5. If the cell 13 is determined
to have insufficient power after the a signal detected by voltage
detector 2 in the motive power allocation unit 4 is computed, the
automobile air-conditioning system 5 will be started and operated
completely by the motive power outputted by the engine 6.
[0024] The automobile air-conditioning system 5 comprises: an
electromagnetic clutch 51 and a mechanical compressor 52 coupled to
the electromagnetic clutch 51. The electromagnetic clutch 51 is
electrically coupled to the motive power allocation unit 4. When
the electromagnetic clutch 51 is driven and engaged with the motive
power allocation unit 4, the relative proportion of motive power
outputted by the motive power allocation unit is used for driving
the mechanical compressor 52 to operate and compressing the Freon
to flow, such that the cool air produced by the automobile
air-conditioning system 5 is entered into the automobile.
[0025] After a driver starts the automobile air-conditioning system
5 while the automobile is being driven, the voltage detector 2
transmits the detected signal of the cell 13 to the motive power
allocation unit 4 for computation. If the electric power of the
cell 13 is considered sufficient after the computation is performed
by the motive power allocation unit 4, the motive power allocation
unit 4 will allocate a lower percentage (such as 30%) of the motive
power outputted by the motor 3 or even turn off the motor 3. If the
motive power with a higher percentage (such as 70%) is outputted by
the motor 3 or the motor 3 is turned off, the motive power with a
percentage of 100% outputted by the engine 6 will be used for
engaging the electromagnetic clutch 51 to drive the mechanical
compressor 52 to operate and compress the Freon to flow, such that
the cool air produced by the automobile air-conditioning system 5
will be entered into the automobile.
[0026] If the cell 13 is determined to have insufficient power
after the signal 4 detected by the voltage detector 2 in the motive
power allocation unit is computed, then 100% of the motive power
outputted by the engine 6 will be used for starting and engaging
the electromagnetic clutch 51 of the automobile air-conditioning
system 5 and driving the mechanical compressor 52 to operate, and
compressing the Freon to flow, such that the cool air produced by
the automobile air-conditioning system 5 will be entered into the
automobile.
[0027] If the power outputted by the cell 13 is low, the motive
power for driving the operation of mechanical compressor 52 of the
automobile air-conditioning system 5 totally comes from the motive
power outputted by the engine 6. The cell 13 will use the electric
power outputted from the solar panel 11 and adopt the electric
charger 12 for the charging. If the cell 13 is determined to be
recovered from its electric power after the signal detected by the
voltage detector 2 and transmitted to the motive power allocation
unit 4 is computed, the motive power allocation unit 4 will
immediately allocate a hybrid motive power with a lower percentage
(such as 30%) of the motive power outputted by the motor 3 and a
higher percentage (such as 70%) of the motive power outputted by
the engine 6 to drive the mechanical compressor 52 to operate, such
that the cool air produced by the automobile air-conditioning
system will be entered into the automobile.
[0028] Therefore, the motive power allocation unit 4 can allocate a
relative proportion of motive power for the output while the
automobile is being driven, so as to reduce the gas consumption and
the loss of motive power of the engine 6 and also save fuels.
[0029] The present invention are illustrated with reference to the
preferred embodiment and not intended to limit the patent scope of
the present invention. Various substitutions and modifications have
suggested in the foregoing description, and other will occur to
those of ordinary skill in the art. Therefore, all such
substitutions and modifications are intended to be embraced within
the scope of the invention as defined in the appended claims.
