The invention provides a refrigerant recoverer circuit. The refrigerant recoverer circuit comprises a detection module, an AD conversion module, a reference voltage module, a processor, a first driving module and a second driving module, wherein the input end of the detection module is connected with an external sensor, and the output end of the detection module is connected with the input end ofthe AD conversion module; the input end of the AD conversion module is also connected with the output ends of the reference voltage module and the processor; the processor is connected with the inputends of the AD conversion module, the first driving module and the second driving module respectively; the output end of the first driving module is connected with the control ends of a plurality of pipeline valves; and the output end of the second driving module is connected with the power supply ends of a compressor and a vacuum pump. According to the refrigerant recoverer circuit, the state ofrecovered refrigerant is automatically obtained, and in combination with the state of the recovered refrigerant, various functions of vacuum pumping, refrigerant filling, refrigerant oil filling, airconditioner pipeline cleaning and the like can be realized, so that various use requirements of users are met, manual misoperation is avoided, and the working efficiency and quality are improved.
Description
technical field [0001] The invention relates to the field of refrigerant recovery and refrigeration, in particular to a circuit of a refrigerant recovery machine. Background technique [0002] The refrigerant recovery machine is used to recover the refrigerant of the refrigerator. Commonly used refrigerators include civil or commercial air conditioners, freezers, heat pump units, and screw centrifugal units. The control circuit of the current refrigerant recovery machine is very simple, consisting of a power switch, an overload protector, a high-voltage switch, a compressor, and a fan. When the power switch is turned on, the current flows through the overload protector and high-voltage switch in turn to drive the compressor and fan to work. , to recycle the refrigerant, when the pressure of the refrigerant tank is too high, the high-pressure switch disconnects the compressor to stop working. [0003] The current refrigerant recovery machine has the following disadvantages: ...
