Abstract

The two-stage metal hydride automobile air conditioner refrigerates via the heat effect of reversible reaction between metal hydride and hydrogen. Waste heat of tail gas as high temperature heat source and peripheral atmosphere as medium temperature heat source are utilized to drive the refrigerating circulation of metal hydride, and two pairs of metal hydride reactors are adopted for alternate refrigeration to continuous regulation of temperature inside the automobile. The air conditioner system includes mainly high and low temperature metal hydride reactors, heat exchanger, solenoid valve, water pump, blower, etc. Inside both the high temperature and the low temperature reactors, are arranged fine pipes with filled metal hydride and hydrogen penetrating film in the middle section of pipes and hydrogen collecting general pipe. The air conditioner has no corrosion, no wear, less motion parts, high vibration resistance, no damage to atmosphere ozone layer and other advantages.

Description

[technical field] [0001] The invention relates to an automobile air conditioner, in particular to an automobile air conditioner system which utilizes waste heat in automobile exhaust as a driving force and realizes refrigeration through the thermal effect of the reversible reaction between metal hydrides and hydrogen, and belongs to energy saving and air conditioning and refrigeration field of engineering technology. [Background technique] [0002] The rapid spread of air conditioners has led to a sharp increase in energy consumption. According to reports, the annual energy consumption for air conditioning in the United States accounts for 35% of the total energy consumption in the United States. In China, with the rapid economic development, the proportion of energy consumption of air conditioners is also increasing rapidly year by year. Today, most of the air conditioners used in automobiles are compression-type freon refrigerators driven by automobile engines. Conventio...
