PURPOSE: To provide a heat source in which pumping heat quantity to the heat quantity of the source is increased, a temperature rising width is improved, and refrigerant for inhibiting to destroy ozone in a stratosphere is used.
CONSTITUTION: In a heat source having a regenerator 2, a condenser 3, an evaporator 4, a solution heat exchanger 6, an absorber 5, solution transport means, refrigerant transport means, and an absorption type heat pump 6 formed of a pipe system for operatively connecting them, a compressor 17, a heat radiator, a heat absorber, a pressure reducing unit, and a pipe system for operatively connecting them, are provided, and a compression type heat pump 16 for circulating second refrigerant is provided. The radiator of the pump 16 is so provided in any of the regenerator or the evaporator of the absorption type pump as to be able to be heat exchanged. Particularly, gas refrigerant is used as second refrigerant of the pump 16, and the pressure reducing device 20 is formed of an expansion unit.
