Abstract
The invention discloses an electric automobile air conditioner system and a control method thereof, belongs to the field of cooling and heating of electric automobiles and aims to solve the technical problem about how to improve the heating capacity and the cooling capacity of the electric automobile air conditioner system to reduce power consumption. The structure of the electric automobile air conditioner system comprises an electric compressor, a condenser assembly, an air conditioner host and a communication device, wherein the electric compressor, the condenser assembly and the air conditioner host are communicated through the communication device to form a cooling loop and a heating loop; a control panel comprises a controller, an electric compressor switch, a fan switch, an exhaust fan switch and an electric heating switch. The control method of the electric automobile air conditioner system comprises the following steps: controlling operation of the electric compressor, the fan, the exhaust fan and a PTC electric heater via the control panel; controlling electromagnetic valves on a pipeline I, a pipeline II and a pipeline III to enter the operation state via the control panel; and controlling electromagnetic valves on a pipeline IV, the pipeline II and a pipeline V to enter the operation state.
Description
technical field [0001] The invention relates to the field of refrigeration and heating of electric vehicles, in particular to an electric vehicle air conditioning system and a control method thereof. Background technique [0002] Compared with conventional vehicles, that is, fuel vehicles, electric vehicles replace the power system of conventional vehicle fuel engines with power sources, resulting in the use of compressors for engine-driven air-conditioning systems on conventional models and heating through engine cooling systems. Wind systems can no longer be used on electric vehicles. In the electric vehicle, the power source is the power supply, so the compressor in the air conditioning system is replaced with an electric compressor, and the water heater in the heating system is replaced by an electric heater PTC. Since the electric compressor and electric heater of the electric air conditioning system consume electric energy of the electric vehicle, if the electric ener...
