Abstract
An auxiliary thermal storage heating and air conditioning system having an output for selectively delivering warm and cool air to the passenger area of a motor vehicle incorporates a reactor containing a metal salt or a complex compound formed by absorbing a polar gas refrigerant on a metal salt comprising a halide, nitrate, nitrite, oxalate, perchlorate, sulfate or sulfite of an alkali metal, alkaline earth metal, transition metal, zinc, cadmium, tin or aluminum, or sodium borofluoride or a double metal halide. In a preferred embodiment, the reactor contains a sorbent/substrate composition comprising a substrate material inert to the polar gas and incorporating the salt or the complex compound. One embodiment utilizes apparatus having a heat exchanger which selectively functions as an evaporator for a cooling mode and a condenser for a heating mode, and inside and outside coils for transferring system generated thermal energy. Another embodiment of the system uses a refrigerant circulatory system having a circuitous refrigerant line and an evaporator and condenser serially disposed within the circuitous line and a multi-channel ventilation system having a blower for forcing air th…
