Title:
HOT WATER SUPPLY APPARATUS USING AIR-SOURCE HEAT PUMP
Document Type and Number:
WIPO Patent Application WO/2017/007194
Kind Code:
A1
Abstract:
The present invention relates to a hot water supply apparatus for supplying hot water by using an air-source heat pump, the apparatus comprising: a heat storage tank (110) for storing a heat storage medium; a first condensing part (120) provided in the heat storage tank (110), and increasing the temperature of the heat storage medium and performing primary condensation while a high-temperature and high-pressure refrigerant circulates therein; and an outdoor unit (200) comprising a compressor (210) compressing a low-temperature and low-pressure refrigerant to high temperature and high pressure so as to transfer the compressed refrigerant to the first condensing part (120), a second condensing part (220) provided so as to perform secondary condensation while the refrigerant, discharged from the first condensing part (120), circulates therein, an expansion valve (230) for expanding, at low pressure, the refrigerant condensed in the second condensing part (220) and discharged therefrom, and an evaporation part (240) for evaporating the refrigerant discharged from the expansion valve (230), so as to transfer the evaporated refrigerant to the compressor (210), wherein the second condensing part (220) and the evaporation part (240) comprise a refrigerant coil unit (C), comprising at least two rows of refrigerant coils, such that the second condensing part and the evaporation part are integrated so as to exchange heat with each other.
