Heat pump cold and warm, hot water machine unit of air source

Abstract

The invention provides a cold-warm hot water set of an air source heat pump, wherein an outlet of a compressor (1) is connected to an inlet of an oil-gas separator (2), a first plate heat exchanger (5) is connected to a gas inlet of a four-way valve (7); an a interface of the four-way valve (7) is connected to a B interface of a reservoir (19) through a second plate heat exchanger (6), a second expansion valve (18) and a check valve (21); a b interface of the four-way valve (7) is connected to a D interface of the reservoir (19); a c interface of the four-way valve (7) is connected to a C interface of the reservoir (19). The set realizes multi-function of supplying cold, supplying heat as well as hot water, and has five operation modes of supplying cold gas, supplying warm gas, supplying hot water, supplying cold gas+hot water, supplying warm gas+hot water. During the operation mode of supplying cold gas+hot water, the domestic hot water is produced by the condensation heat generated during the refrigeration, and is supplied for free. The set has advantages of environmental protection, energy conservation and multipurpose.

Description

technical field [0001] The invention relates to the technical fields of air-conditioning and refrigeration, waste heat recovery, and heating and heating, in particular to an air-source heat pump cooling and heating water unit. Background technique [0002] Nowadays, there are many air conditioners, and most of them use simple cooling or simple heating methods. The heat pump water heaters used now only supply hot water below 60°C. These are all single-type jobs, and the energy utilization rate is low. Be utilized, produce greenhouse effect, pollute environment, do not meet the requirement of energy saving and environmental protection. Contents of the invention [0003] The object of the present invention is to design an environment-friendly, energy-saving and multi-purpose air source heat pump cooling, heating and heating water unit by utilizing the air source. [0004] The air source heat pump cooling and heating water unit of the present invention includes: [0005] Com...
