Automobile Solar Air-Conditioning Control System

Abstract

An automobile solar air-conditioning control system includes a solar energy supply device, a control device, a power device and an automobile air-conditioning system. When the engine of the vehicle stops running, after the driver presses a button of the control device, the signals output by the control device and the power output by the solar energy supply device are used to actuate the power device to drive a mechanical compressor of the automobile air-conditioning system to operate. As a result, the automobile air-conditioning system generates and introduces cold air into the vehicle, thereby to maintain the temperature in the vehicle in a suitable range.

1 . An automobile solar air-conditioning control system for an engine-powered vehicle, the vehicle having an engine-driven air-conditioning system, the air-conditioning system having a mechanical compressor and connected to the engine via a first electromagnetic clutch, the control system comprising:
 a solar energy supply device for converting solar energy into electricity and outputting the converted electricity;   a control device electrically connected to the solar energy supply device and including:
 a micro processing unit electrically connected to the solar energy supply device and serving as a control center of the whole control device; 
 a temperature-sensing unit electrically connected to the micro processing unit for sensing the temperature in the vehicle; 
 an operating device electrically connected to the micro processing unit for setting a desired temperature value and starting/stopping the control device; 
 a switch unit electrically connected to the micro processing unit and the solar energy supply device and driven by the output signal of the micro processing unit to control the active or inactive state of a power supply; 
   a power device including:
 a motor electrically connected to the switch unit and driven by the power output by the electricity conversion unit after the switch unit is actuated; 
 a second electromagnetic clutch electrically connected to the micro processing unit and mechanically connected to the motor and the mechanical compressor; 
   wherein after a button of the operating unit is pressed, if the temperature value sensed by the temperature-sensing unit is higher than a preset value, the micro processing unit outputs a signal to synchronously actuate the switch unit and the second electromagnetic clutch, and thus the motor drives the mechanical compressor to operate; if the temperature value sensed by the temperature-sensing unit is lower than a preset value, the micro processing unit does not output a signal and thus makes the switch unit and the second electromagnetic clutch inactive.   
   
   
       2 . The automobile solar air-conditioning control system according to  claim 1 , wherein the solar energy supply device includes:
 a solar plate for converting sunlight into electricity and outputting the converted electricity;   a charging unit electrically connected to the solar plate;   a battery unit electrically connected to the charging unit for saving the voltage output by the charging unit; and   an electricity conversion unit electrically connected to the switch unit for converting the voltage output by the battery unit into a voltage output to drive the motor.   
   
   
       3 . The automobile solar air-conditioning control system according to  claim 2 , wherein the battery unit is an accumulator. 
   
   
       4 . The automobile solar air-conditioning control system according to  claim 2 , wherein the electricity conversion unit is a transformer. 
   
   
       5 . The automobile solar air-conditioning control system according to  claim 1 , wherein the operating unit is constituted of a plurality of buttons. 
   
   
       6 . The automobile solar air-conditioning control system according to  claim 1 , wherein the switch unit is a relay. 
   
   
       7 . The automobile solar air-conditioning control system according to  claim 1 , wherein the control device further includes a display unit electrically connected to the micro processing unit for displaying the temperature in the vehicle and setting a desired temperature value.
