A heat pump with a high coefficient of performance and a dehumidifying apparatus consumes a small amount of energy per amount of moisture removal. The heat pump includes a pressurizer for raising a pressure of a refrigerant; a condenser for condensing the refrigerant to heat a high-temperature heat

A heat pump with a high coefficient of performance and a dehumidifying apparatus consumes a small amount of energy per amount of moisture removal. The heat pump includes a pressurizer for raising a pressure of a refrigerant; a condenser for condensing the refrigerant to heat a high-temperature heat source fluid; an evaporator for evaporating the refrigerant to cool a low-temperature heat source fluid; and heat exchanger disposed in a refrigerant path connecting the condenser and the evaporator for evaporating and condensing the refrigerant under an intermediate pressure between the condensing pressure of the condenser and the evaporating pressure of the evaporator 210. The low-temperature heat source fluid is successively cooled by the heat exchanging means, cooled by the evaporator, and heated by the heat exchanger in such order. The low-temperature heat source fluid can be precooled by the heat exchanger prior to cooling in the evaporator, and the amount of heat removed in the precooling process can be recovered from the low-temperature heat source fluid which has been cooled by the evaporator.
