Embodiment Construction
[0015] The present invention will be described in detail below with reference to the accompanying drawings.
[0016] Such as figure 1 As shown, the present invention provides an air-conditioning system, including an evaporator 3, a compressor 7, a blower 5 and a temperature sensor 4, and also includes an air-conditioning control unit 1, an air-conditioning drive unit 2 and a CAN bus 8, and the air-conditioning control unit 1 is respectively The evaporator 3, the blower 5 and the temperature sensor 4 are connected, the air conditioner drive unit 2 is connected to the compressor 7, and the air conditioner control unit 1 obtains the gear position of the compressor 7 according to the actual temperature value of the evaporator 3 detected by the temperature sensor 4 output value, and control the air conditioner driving unit 2 to drive the compressor 7 to work through the CAN bus 8 .
[0017] The air-conditioning control unit 1 is the main air-conditioning control unit on the vehicl...

The invention provides an air conditioning system and a control method. The system comprises an evaporator, a compressor, a blower, a temperature sensor, an air conditioning control unit, an air conditioning driving unit and a CAN bus, wherein the air conditioning control unit is connected with the evaporator, the blower and the temperature sensor respectively; the air conditioning driving unit is connected with the compressor; and the air conditioning control unit obtains a gear output value of the compressor according to an actual temperature value of the evaporator detected by the temperature sensor and controls the air conditioning driving unit to drive the compressor to work through the CAN bus. Due to the adoption of the structure and the control method of the air conditioning system, the rotation speed of the compressor meets the requirements of no evaporator protection, and meets the refrigerating requirement of a user along with the temperature adjustment of the evaporator and the user cannot feel abnormal protection of the air conditioning compressor, and the low rotation speed of the compressor can also effectively save the energy, reduce the noise and the vibration and improve the comfort of drivers.
Description
technical field [0001] The invention relates to an air conditioning system and a control method, in particular to an electric vehicle air conditioning system and a control method. Background technique [0002] Nowadays, most vehicles are equipped with air-conditioning devices. The air-conditioning of traditional fuel vehicles needs to be driven by the engine to run normally, and the speed-regulating belt drives the compressor to run to cool the air-conditioning. This traditional air-conditioning control The system brings comfort and convenience to people when driving, but it also brings some problems of the air-conditioning system. When the air-conditioning system of a traditional fuel vehicle is working, the engine must be turned on first, and then the air-conditioning control module detects the current temperature or people manually operate to start the refrigeration. Link with the engine, so that the engine drives the compressor to rotate for a process by driving the pul...
