Solar air-conditioner consists of heat collector,Direct-fired engine,Lithium –Bromide refrigeration units and energy-storage tank.Parahboloidal focuaing Vacuum tube and endothermic plate as the colletor that driving maching drives the reflector and cacuum tube to follow the sun,focusing sunlights on the vacuum tube always.Made of imported mirror aluminum,the reflector coated with anti-gray material,and the reflectivity reached to 82%.Mid-temperatured straight vacuum tubes,with high collector efficiency,It canrefrigerate and heat for industry requirement and for buildings like residental house,supermarket,exhibition hall,school,gymnasium,office building,hospital,hotel,workshop and so on.Use solar in daytime , and nature gas or other heat resouce as complements in night or rainy days. Redundant solar energy can be stored in storage tank, automatically run all through the year.
