Problems solved by technology
[0003] The air conditioning compressor of a traditional diesel car is driven by the engine. When the engine speed is constant, the cooling capacity of the air conditioning system is constant. As the temperature rises, the cooling effect becomes worse, the cooling capacity of the air-conditioning system cannot meet the cooling needs of the car, and the subjective feeling is that the air-conditioning effect is poor

The invention discloses a two-stage compressed vehicle air conditioner system and a control method thereof. In an existing vehicle air conditioner system, a two-stage compressor is used, an environment sensor signal is obtained through a controller, and the work state of the vehicle air conditioner system is changed. When the external environment temperature is too high and sunlight load outside avehicle is too large, the vehicle air conditioner system is in a second state, and the refrigeration efficiency is improved; when the external environment is in a normal state, the vehicle air conditioner system is in a first state, and energy can be saved. According to the vehicle air conditioner system, the signal of the environment sensor is obtained by utilizing the controller, the work states of a first control valve and a second control valve are changed, and the refrigeration efficiency and driving comfort level are improved.
Description
technical field [0001] The invention relates to the technical field of vehicle systems, in particular to a two-stage compression automotive air-conditioning system and a control method thereof. Background technique [0002] The automobile air conditioner has the function of cooling and cooling the cab. The main principle is that the refrigerant is driven by the compressor and in a closed system composed of compressors, condensers, evaporators, throttle valves, pipelines and other components. Do circular motions. Driven by the fan, the hot air in the cab exchanges heat with the refrigerant inside the evaporator, thereby reducing the temperature of the hot air and achieving the cooling effect. [0003] The air conditioning compressor of a traditional diesel vehicle is driven by the engine. When the engine speed is constant, the cooling capacity of the air conditioning system is constant. As the temperature increases, the cooling effect becomes worse, and the cooling capacity...
