Heat pump type speed heating apparatus

摘要

PURPOSE: A heat pump type hot water supply apparatus is provided to accumulate heat in a thermal energy storage tank using the condensation heat of a refrigerant of a hydro kit heat exchange unit. CONSTITUTION: A heat pump type hot water supply apparatus comprises a cooling cycle circuit(2), a thermal energy storage tank, and a hydro kit het exchange unit(H). The cooling cycle circuit is composed of a compressor(12), indoor and outdoor heat exchangers(18,14), and expanding units(16,17). The thermal energy storage tank stores heat exchanged with refrigerants flowing from the cooling cycle circuit. The hydro kit heat exchange unit comprises first and second heat exchangers(74,72). The first heat exchanger firstly condenses refrigerants compressed from the compressor and sends heat exchanged during condensation to the thermal energy storage tank. The second heat exchanger secondly condenses the condensed refrigerants and sends heat exchanged during condensation to the thermal energy storage tank.
