随着人类对汽车空调环保及节能要求的提高,需要发展新型空调制冷系统。 With the improvement of environmental protection and energy saving automotive air-conditioning requirements, requiring the development of new air conditioning and refrigeration systems. 在已有的技术中,申请号为99116689.2,名称为“汽车用溴化锂吸收式制冷装置,申请号为98113317.7,名称为“以汽车尾气热量为能源的空调机”,均是以水为制冷剂,制冷温度只能在0℃以上,溴化锂溶液具有腐蚀性,而且汽车的振动和倾斜严重影响吸收器和发生器的运行,从而降低制冷效果。 In the prior art, Application No. 99116689.2, entitled "Vehicle Absorption Refrigeration apparatus, Application No. 98113317.7, entitled" In vehicle exhaust heat energy of the air conditioner ", are based on water as the refrigerant, only refrigerating temperature above 0 deg.] C, corrosive lithium bromide solution, and the tilt and vibration of the car and seriously affect the operation of the absorber to the generator, thereby reducing the cooling effect.

[发明内容]为了克服已有技术的不足和缺陷,本发明设计了一种全新的环保节能型的汽车空调,该空调利用汽车尾气中的废热作为高温热源,外界大气环境作为中温热源来驱动金属氢化物制冷循环,通过金属氢化物与氢气之间可逆反应的热效应来实现制冷,采用两对金属氢化物反应器交替制冷来实现汽车室内空气温度的连续调节。 [SUMMARY] To overcome the prior art disadvantages and drawbacks, the present invention contemplates a new green energy-saving vehicle air conditioner, the air conditioner in the vehicle exhaust waste heat as a high temperature heat source, as the ambient atmosphere to the hot heat source metal hydrides driving a refrigeration cycle, cooling is achieved using two pairs of continuous adjustment of the metal hydride reactor alternately cooling the room air temperature to achieve automotive metal hydride by thermal effects of the reaction between hydrogen and reversible.
