High-efficiency eco-friendly heat pump system for cold hot and hot water production using air heat and water

摘要

The present invention relates to a combined eco-friendly and high-efficiency heat pump system for producing cold water, hot water, and hot water using air heat and water, and more particularly, it includes an outdoor unit and an indoor unit, and performs heat exchange between the heating medium and the outdoor air in the outdoor unit, and the heating medium in the indoor unit A heat pump system in which a heating medium circulates between an outdoor unit and an indoor unit in order to perform another heat exchange between an indoor unit and an outdoor unit, the heat pump system comprising: a compressor for sucking and compressing the heating medium and discharging the resultant heating medium; a first heat exchanger for evaporating the heat medium through an expansion valve to produce 5 to 7° C. cold water; a second heat exchanger for producing hot water at 50 to 55°C by condensing the high-temperature and high-pressure heating medium with groundwater or tap water exchange; and an accumulator that acts to separate the heating medium into gas and liquid, and accumulating the heating medium in a liquid phase. According to this, there is an effect that hot water can be produced and supplied free of charge by using the condensing temperature of the heat exchanger generated during cold water production.
