ヒートポンプ給湯機
Document Type and Number:
Japanese Patent JP6747608
Kind Code:
B2
Abstract:
Conventionally there are heat pump hot water supply devices equipped with an internal heat exchanger for exchanging heat between a high-pressure refrigerant flowing into a decompression device from a compressor and a low-pressure refrigerant flowing into the compressor from the decompression device. However, there is a problem in that it is not possible to prevent a low-pressure refrigerant from reaching a gas-liquid two-phase state with the amount of heat provided to the low-pressure refrigerant from the high-pressure refrigerant, as in conventional heat pump hot water supply devices. The heat pump hot water supply device according to the present invention is equipped with a water heat exchanger for exchanging heat between a high-pressure refrigerant, a low-pressure refrigerant, and water. Heat is supplied to the low-pressure refrigerant from the high-pressure refrigerant and the water, so the low-pressure refrigerant can be prevented from reaching a gas-liquid two-phase state.
