Problems solved by technology

[0004] The refrigeration process of the automobile air conditioner of the above-mentioned invention is intermittent, and two sets of devices must be used to realize continuous refrigeration, and the efficiency is also low. The combined operation of the vapor compression refrigeration system, if it is supplemented by vapor compression refrigeration, the device is too complicated, and the volume is large, and the price of metal hydride is very expensive, it is unrealistic to realize it on the existing car

Embodiment Construction

[0012] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the present invention includes: generator 1, steam ejector 2, A check valve 3, B check valve 4, compressor 5, condenser 6, liquid receiver 7, expansion valve 8, evaporator 9, Solenoid valve 10, expansion valve temperature sensing package 11, vapor-liquid injector 12, heat exchange tube 13, three-way regulating valve 15, C check valve 16, temperature sensor 17, liquid level sensor 18. The compressor 5 adopts a variable-displacement automotive air-conditioning compressor, which can adjust the cooling capacity for different vehicle speeds. The three-way regulating valve 15 is located on the exhaust gas outlet pipe, and the heat exchange tube 13 is placed in the generator 1 for heating the exhaust gas in the generator 1. The refrigerant. The outlet of the automobile exhaust pipe 14 is connected with the inl...

Abstract

The system includes generator, vapor - vapor injector, compressor, condenser, expansion valve, evaporator, vapor - liquid injector, and heat exchange tube etc. In procedure of using air condition, refrigeration in jet type driven by residual heat of tail gas is always operated; and compressor to compress refrigerant supplies deficient cool quantity. The said two methods share same set of condenser, evaporator, and expansion valve. Based on current refrigerating system, the invention uses residual heat of tail gas by adding few parts and cost so as to realize energy saving. Comparing prior art, the system saves energy about 10úÑ for general saloon car, and saves more energy for saloon cars in large and middle size. Features are: no moving part, simple and reliable.

Description

technical field [0001] The invention relates to an automobile air-conditioning and refrigeration system, in particular to an automobile air-conditioning and refrigeration system driven by a compressor capable of recovering waste heat of automobile tail gas and tail gas waste heat, and belongs to the technical field of refrigeration and air-conditioning. Background technique [0002] The current automobile air-conditioning refrigeration system basically adopts the traditional vapor compression refrigeration system. The compressor is driven by the automobile engine. The low-pressure gaseous refrigerant is compressed by the compressor and enters the condenser to condense into a high-pressure liquid refrigerant, which is then throttled by the expansion valve. Then it enters the evaporator to evaporate, thus completing a cycle. The power of this refrigeration system comes entirely from the mechanical work of the engine. The mechanical work of the engine is obtained by the expansio...
