Problems solved by technology

However, the heat exchanger used for condensation heat exchange is completely placed inside the air circulation shell, and the headwind caused by the speed of the vehicle cannot be used to improve the heat exchange efficiency of the condenser, and the condenser must have a large windward area, resulting in its bulky and difficult to arrange
At the same time, since the heat transfer from the condenser to

Abstract

The present invention relates to an air conditioning system for automobiles, characterized in that: the first air circulation housing is used to guide the air flow; the evaporator is arranged in the first air circulation housing, and the air flow in the first air circulation housing all flows through the evaporation device; the first blower is arranged in the first air circulation shell to generate air flow; the first outlet guides the air in the first air circulation shell to flow out of the shell; the air conditioning system is provided with the least number of valves in the refrigerant circuit, At the same time, an air guiding device is arranged in the air circulation shell, and the switching between the cooling/dehumidification working mode and the heating working mode of the system is realized through the joint action of the valve and the air guiding device. Reduce the volume of the system and improve the cooling/heating efficiency of the system at the same time, that is, it can be realized with the least number of parts, and the volume is small and the efficiency is high.

Description

technical field [0001] The invention relates to an air-conditioning system for automobiles, which is used for automobiles and integrates cooling and heating. Background technique [0002] At present, with the continuous upgrading of automobile emission regulations, automobiles are gradually reducing their emissions, and are further developing into new energy forms such as hybrid electric vehicles and pure electric vehicles. However, it has brought about technical problems in automotive air conditioning: the engines of small-displacement vehicles have less waste heat available in winter, hybrid vehicles have no heat source when driving purely electric, and pure electric vehicles have no heat source. The above situation has caused vehicle heating and defrosting in winter / Defog requirements cannot be met, reducing driving comfort and even affecting driving safety. There are two known solutions, PTC heater and heat pump air conditioning system. PTC heaters are simple and rel...
