An air source low temperature triple heat pump water heater unit and its realization method

Abstract

The invention discloses an air-source low-temperature triple heat pump hot water unit and a realization method thereof, which solves the problem that the heat pump unit has a single function and is difficult to meet demands. The present invention comprises a compressor provided with a liquid injection port, an economizer connected with the liquid injection port of the compressor, a separator with an output end connected with the input end of the compressor, a three-way valve connected with the output end of the compressor, and a three-way valve connected with the output end of the compressor. The hot water processing device connected by the one-way valve, the four-way valve connected on the pipeline between the three-way valve and the hot water processing device, the evaporator and the second condenser respectively connected with the four-way valve, and the second condenser respectively Connected circulating pump and annular one-way valve group, liquid storage tank connected with annular one-way valve group and economizer respectively, and fan corresponding to evaporator; separator is connected with four-way valve, evaporator and economizer They are respectively connected with the annular one-way valve group; there is also a solenoid valve between the liquid storage tank and the economizer. The invention has reasonable structure, various functions, convenient use and is suitable for popularization.

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...
