Problems solved by technology
[0005] The scheme of adding heat dissipation vents (including air inlet and air outlet) on the battery box is passive heat dissipation, which completely relies on air-cooled heat dissipation during vehicle driving. One of the disadvantages of this scheme is that the waterproof level is not high (currently IP55 can be achieved) , can not meet the requirements of electric vehicles wading, the second disadvantage is that the heat dissipation effect mainly depends on the external temperature, especially in hot cities, the heat dissipation effect is not ideal
[0006] The method of adding a cooling fan in the battery box is an active cooling method, which can achieve a high waterproof level (currently IP67), and can meet the requirements of wading. Since the wind provided by the fan is not a cold wind, the disadvantage of this solution is that the heat dissipation is slow

The invention discloses an air-conditioning system for an electric vehicle, and belongs to the field of air conditionings for electric vehicles. A first two-way valve and a second two-way valve are arranged on the conventional refrigeration system for the electric vehicle; the output end of a compressor is connected with air inlet valves of the first two-way valve and the second two-way valve through pipelines respectively; an air outlet valve of the first two-way valve is connected with a heating ventilation air conditioning (HVAC) system through a pipeline; and an air outlet valve of the second two-way valve is connected to a battery box which is used for placing a power battery and the like through a pipeline. When a user turns on an air-conditioning switch for refrigeration, if the temperature of the battery box is too high, the first two-way valve and the second two-way valve both act so as to refrigerate a passenger compartment and the battery box of the electric vehicle respectively; and when the user does not turn on the air-conditioning switch for refrigeration, if the temperature of the battery box is too high, the first two-way valve does not act, and the second two-wayvalve acts to refrigerate the battery box only, so the temperature in the battery box is reduced, and the aim of radiating heat well is fulfilled.
Description
technical field [0001] The invention relates to an electric vehicle air conditioning system, in particular to an electric vehicle air conditioning system which can not only cool the passenger compartment of the electric vehicle but also cool the power battery box when the temperature of the power battery is too high. Background technique [0002] The early air-conditioning system of pure electric vehicles was mainly composed of two parts, namely, the electric air-conditioning compressor and the air-conditioning pipeline system for gasoline vehicles. The machine is not suitable for pure electric vehicles. In order to meet the cooling needs of the drivers and passengers in the cab of pure electric vehicles in summer, and to reduce the design workload, electric compressors are generally used to replace the original gasoline vehicle compressors and the ventilation of the original gasoline vehicle HVAC system is used. The way of pipeline system realizes the cold air demand in sum...
