Multipurpose heat pump units

Abstract

The invention discloses a multi-purpose heat pump unit, which configures a heat pump unit providing hot water and floor heating, or configures a two-in-one heat pump unit providing air-conditioning refrigeration and floor heating, or configures a three-in-one heat pump unit which can provide hot water, air-conditioning refrigeration, and floor heating together. The heat pump unit is formed through adding one or two heat exchangers to the heat pump air conditioning unit, and through the carnot circulation or reverse carnot circulation, or through the switch of the control valve, in reverse carnot circulation and conversions between the carnot circulation, and through utilizing the process of heat release and absorption of the high-pressure and high-temperature refrigerant in the compressor. The multi-purpose heat pump unit has advantages of saving equipment investment, improving the efficiency of energy utilization, and reducing the cost and reducing the environmental pollution.

Description

technical field [0001] The invention relates to a multi-purpose heat pump unit for air-conditioning refrigeration, floor heating and domestic hot water supply. Background technique [0002] With the improvement of people's living standards, air conditioners are generally used in buildings for cooling in summer, and steam boilers are used for heating in winter; hot water boilers are used to provide domestic hot water throughout the year, so multiple investments are required, resulting in increased operating costs and energy waste. environmental pollution. [0003] The air conditioning unit currently used generally includes a refrigerant side cycle composed of a compressor 1, an air conditioner heat exchanger 6, an expansion valve 8, a dry filter 14 and a gas-liquid separator 2, and a water side cycle of the air conditioner heat exchanger 6. , its function is relatively simple, usually only provides air conditioning, does not provide floor heating and domestic water.
