| 摘要 |
The present invention relates to a hot water producing device using a heat pump. The heat pump is composed of a refrigeration cycle comprising a compressor, a condenser, a liquid receiver, an expansion valve, an evaporator, and an accumulator, and heats water using heat emitted from the condenser. The condenser is composed of multiple plate type heat exchangers, multiple double-pipe heat exchangers, or multiple shell and tube heat exchangers in which refrigerant inputted through a refrigerant inlet and discharged through a refrigerant outlet and hot water inputted through a hot water inlet and discharged through a hot water outlet independently and alternatively circulate in a refrigerant circulating passage and a hot water circulating passage. |
