Abstract

A heat pump type speed heating apparatus according to the present invention comprises a cooling cycle circuit capable of operating air conditioning, and a hot water supply circuit where a second refrigerant heats water of a hot water supply tank. The hot water supply circuit comprises a hot water supply compressor to compress a second refrigerant; a hot water supply heat exchanger where the second refrigerant compressed in the hot water supply compressor is condensed while heating water; a hot water supply expansion apparatus where the second refrigerant condensed in the hot water supply heat exchanger is expanded; and a cascade heat exchanger connected to the cooling cycle circuit for the first refrigerant discharged from the compressor to evaporate the second refrigerant expanded at the hot water supply expansion apparatus and undergo a process of condensation, expansion, and evaporation in the cooling cycle circuit, thereby providing an advantage of improving hot water supply and air conditioning performance.

Description

technical field [0001] The invention relates to a heat pump hot water supply device, in particular to a heat pump hot water supply device capable of utilizing the heat of refrigerant compressed in a compressor for hot water supply and air conditioning. Background technique [0002] Generally speaking, a heat pump uses the heat of heat generation or condensation of a refrigerant to transfer a low-temperature heat source to a high-temperature one, or to transfer a high-temperature heat source to a low-temperature refrigeration and heating device. [0003] Heat pumps include compressors, outdoor heat exchangers, expansion mechanisms, and indoor heat exchangers. Recently, heat pump hot water supply devices tend to be developed, which use compressed refrigerant in compressors to heat water and use it for hot water supply. Minimize fossil fuel consumption. [0004] JP2001-263857A (2001.9.26) discloses a cooling and heating hot water supply device and its control method, wherein t...
