Cold and hot integrated type automobile air conditioning system

Abstract

The invention discloses a cold and hot integrated type automobile air conditioning system. A refrigeration unit and a heating unit are of a common refrigeration sheet assembly, wherein the refrigeration sheet assembly is mounted in the shell; heat radiators are stuck on a heating surface and a refrigeration surface of the refrigeration sheet assembly respectively. Two sets of fans are arranged in the shell and are located on the outer sides of the two heat radiators respectively; the refrigeration sheet assembly can be overturned for 180 degrees by an overturning mechanism so that the positions of the heating surface and the refrigeration surface are exchanged. The system adopts an existing developed refrigeration sheet structure; refrigeration and heating can be realized on the same structure, and one piece can be used for replacing an independent heating system and an independent refrigeration system, the switching is convenient and the structure is simple. When the automobile air conditioning system is used for heating, an engine does not work and a vehicle-mounted power supply is adopted, so that the safety is higher; hot air can be generated without a period of time of work of the engine so that the heating speed is more rapid.

Description

technical field [0001] The invention relates to a vehicle structure, in particular to an air-conditioning system on a vehicle, and belongs to the technical field of vehicles. Background technique [0002] At present, most vehicles are equipped with an air-conditioning system, which consists of two functions: cooling and heating. Among them, refrigeration adopts traditional and mature compressor technology. The compressor compresses gaseous Freon into high-temperature and high-pressure liquid Freon, and then sends it to the condenser to dissipate heat to become medium-temperature and medium-pressure liquid Freon. The liquid freon enters the evaporator through the capillary tube, the space suddenly increases and the pressure decreases, the liquid freon will vaporize (from liquid to gas is a heat-absorbing process), absorbing a lot of heat, the evaporator will become cold, the fan Air is blown through the evaporator, so what comes out is cool air. The principle of car heati...

AI Technical Summary

Problems solved by technology

[0003] The existing automobile air conditioners have the following deficiencies: 1. Although the technology of the refrigeration system is mature, the structure is complicated, the configuration cost is high, and it is prone to failure, and the refrigerant needs to be replaced

If you just rest in a stopped car and need to heat, you must also turn on the engine. This is not only environmentally friendly, but also burns fuel, and there are certain safety hazards, because carbon monoxide poisoning is easy in an environment with no air circulation.
