Abstract: A chemical heat pump utilizing a hydrating agent as the working fluid is disclosed. The clathrate formation reaction of a hydrating agent such as flon 31 or 22 is used as one of the two equilibrium reactions of the working fluid so that heat can be pumped up across a temperature difference greater than that between the two heat sources. The heat pump comprises four container means in which reactions take place so that the regeneration process can be effected simultaneously with the heating or refrigerating process in which the temperature of the thermal medium to be utilized, e.g., water, is raised or lowered. The working fluid flows either in continuous one-directional circulation through the four container means, or in alternate directions therebetween. In addition to the two heat sources at two different temperatures, such as waste heat and open air, the heat pump further comprises gas pipes which allow the free movement of the working fluid between the connected container means.
