PURPOSE: To obtain an inexpensive and convenient chemical heat pump good in efficiency, by a method wherein water as a cooling medium and calcium chloride as an absorbing material are contained as constitutional elements and the amount of water with respect to anhydrous calcium chloride is brought into a specific range to perform operation.
CONSTITUTION: In a chemical heat pump, a tank A and a tank B are connected by a stop valve 1 and heat exchangers 4 are mounted to both tanks A, B. In addition, the apparatus is held under an airtight state after degassing and only steam is present therein. Water 2 is added to the tank A as a cooling medium while calcium chloride is added to the tank B as an absorbing material and the amount of water is brought into a range of 2W10mol (especially, 2W7mol) with respect to one mole anhydrous calcium chloride to perform operation.
