Air-source low-temperature tri-generation heat pump hot water unit and implementation method thereof

Abstract

The invention discloses an air-source low-temperature tri-generation heat pump hot water unit and an implementation method thereof, and solves the problems that functions of a heat pump unit are single and demands are difficult to meet. The air-source low-temperature tri-generation heat pump hot water unit comprises a compressor, an economizer, a separator, a three-way valve, a hot water processing device, a four-way valve, an evaporator, a second condenser, a circulating pump, an annular one-way valve group, a liquid storage tank and a fan, wherein a liquid spray port is formed in the compressor; the economizer is connected with the liquid spray port of the compressor; an output end of the separator is connected with an input end of the compressor; the three-way valve is connected with an output end of the compressor; the hot water processing device is connected with the three-way valve; the four-way valve is connected on a pipeline between the three-way valve and the hot water processing device; the evaporator and the second condenser are connected with the four-way valve respectively; the circulating pump and the annular one-way valve group are connected with the second condenser respectively; the liquid storage tank is connected with the annular one-way valve group and the economizer respectively; the fan corresponds to the evaporator; the separator is connected with the four-way valve; the evaporator and the economizer are connected with the annular one-way valve group respectively; and an electromagnetic valve is further arranged between the liquid storage tank and the economizer. The air-source low-temperature tri-generation heat pump hot water unit is reasonable in structure, multifunctional, convenient to use and suitable for promotion.

Description

technical field [0001] The invention relates to a heat pump unit, in particular to an air source low temperature triple heat supply heat pump hot water unit and its realization method. Background technique [0002] Air-conditioning, heating, cooling and sanitary hot water are essential needs in people's production and life. In low-temperature environments, the most direct way for people to demand sanitary hot water is to use coal-fired water heaters, gas-fired hot water, and electric water heaters. Solar water heaters are used to meet the demand. In winter in the north, household air conditioners are basically unable to achieve the heating effect. The heating method mainly uses municipal central heating or household wall-hung boiler heating to solve the problem. In low-temperature areas, air-source low-temperature heat pump water heaters can only provide domestic hot water or heating. When cooling in summer, most of them are realized by air conditioning. Therefore, the fun...
