An automobile air conditioning system is a device for refrigerating, heating, ventilating and purifying air in a carriage. The automobile seat cushion can provide a comfortable riding environment for passengers, reduce the fatigue strength of a driver and improve the driving safety.
The traditional automobile warm air system mostly adopts water heating type heat supply, and the heat source is cooling liquid of an engine. The automobile heating system mainly comprises a heat exchanger, a cooling liquid pipeline, a blower, an air guide cover, a lower air duct, a control mechanism and the like, wherein a shell of the heating and heating fan unit and a shell of the evaporator are integrated, and the blower, the air duct and the like are shared with the refrigerating system.
The automobile cooling system is divided into a small circulation and a large circulation, wherein the small circulation can quickly raise the temperature of the engine to a proper working temperature, and the large circulation can keep the engine at the proper working temperature. When the engine works, the cooling liquid heated by the high temperature of the combustion of the engine cylinder enters the heat exchanger through the large circulating water pipe under the action of the water pump of the engine cooling system, and the heat emitted by the cooling liquid is sent to the interior of a carriage or windshield glass through the air blown out by the blower so as to improve the temperature in the carriage and defrost the interior of the carriage. The cooling liquid which is subjected to the heat dissipation process in the heat exchanger is pumped back by the water pump through the water return pipe, and the circulation is carried out, so that the heating of warm air is realized.
