Embodiment 1

[0021] A multi-purpose heat pump unit that provides domestic hot water and floor heating in one. Its structural principle is as follows: figure 1 shown.

[0022] Compared with general air conditioning units, this embodiment adds an auxiliary auxiliary heat exchanger 5 and an electric three-way valve 7 . The heat pump is used to provide hot water for floor heating during the reverse Carnot cycle, and the water outlet of the unit is connected to the domestic hot water circulation system and the floor heating water circulation system at the same time, through the electric three-way valve 7 between the domestic hot water circulation and the floor heating circulation switch between. This embodiment can provide floor heating in winter and domestic hot water throughout the year, so one unit can meet the needs of floor heating and domestic hot water at the same time, forming a brand-new system integrating floor heating and domestic hot water. 2-in-1 heat pump unit.

Embodiment 2

[0026] A multi-purpose heat pump unit integrating air-conditioning refrigeration and floor heating, its structural principle is as follows figure 1 shown.

[0027] Compared with general air conditioning units, this embodiment adds an auxiliary auxiliary heat exchanger 5 , a four-way valve 3 and an electric three-way valve 7 . In this embodiment, cooling can be performed in summer and heating can be performed in winter, realizing one machine with two functions.

[0028] refer to figure 2, in this embodiment, the refrigerant output end 1A of the compressor 1 is branched with the refrigerant side end 5A of the auxiliary auxiliary heat exchanger 5 or the refrigerant side of the air conditioner heat exchanger 6 after being branched by the four-way valve 3 The other end 6A of the refrigerant side of the air conditioner heat exchanger 6 is connected to the other end 5B of the refrigerant side of the auxiliary auxiliary heat exchanger 5 through the expansion valve 8 and the dry fil...

Embodiment 3

[0031] A multi-purpose heat pump unit integrating air-conditioning refrigeration, floor heating and domestic hot water. Its structural principle is as follows: image 3 shown.

[0032] Compared with general air conditioning units, this embodiment adds an auxiliary auxiliary heat exchanger 5 , a heat recovery heat exchanger 4 , a four-way valve 3 and an electric three-way valve 7 . This embodiment can cool in summer and heat in winter, and can also supply hot water throughout the year, realizing one machine with three functions.

[0033] refer to image 3 , in this embodiment, the refrigerant output end 1A of the compressor 1 is connected to the four-way valve 3 through the refrigerant side of the heat recovery heat exchanger 4, and is then branched by the four-way valve 3 to exchange heat with the air conditioner One end 6A of the refrigerant side of the heat exchanger 6 or one end 5A of the refrigerant side of the auxiliary auxiliary heat exchanger 5 is connected; The othe...

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. Conten...
