Heat-pump hot-water air conditioning unit and operating method thereof

Abstract

The invention aims to provide a heat-pump hot-water air conditioning unit and an operating method thereof. The heat-pump hot-water air conditioning unit has more optimized performance, can recycle waste heat produced by the air conditioning unit, also can produce hot water by using the energy-efficient heat pump principle, is energy-saving and environmentally-friendly, and is favorable for the realization of multi-mode multifunctional control. The heat-pump hot-water air conditioning unit comprises a control system, an air conditioning outdoor unit, an air conditioning indoor unit, a water heater and a plurality of refrigerant pipelines; a refrigerant circularly flows in the refrigerant pipelines; the water heater comprises a water tank, a hot water generator and a water pipe which is connected with the water tank and the hot water generator; the air conditioning outdoor unit comprises a four-way valve A and a four-valve B, a first port of the four-way valve A is connected with a high-pressure outlet end of a compressor through the first refrigerant pipeline, and a first port of the four-way valve B is connected with the high-pressure outlet end of the compressor through the second refrigerant pipeline; and the hot water generator is arranged between the high-pressure outlet end of the compressor and the four-way valve B, and the second refrigerant pipeline also comprises a heat exchange pipeline section which is positioned inside the hot water generator.

Description

technical field [0001] The invention belongs to the application field of air conditioning technology, and in particular relates to a heat pump hot water air conditioning unit capable of recovering heat and having the function of heating hot water and a working method thereof. Background technique [0002] With the rapid development of society and rapid technological innovation, people's awareness of energy and environmental protection is constantly increasing. With the development of the economy and the improvement of people's living standards, air-conditioning units have better and better market prospects due to their convenient intelligent management, large cooling / heating capacity, and flexible configuration of cooling / heating for different areas. Into more and more homes and offices. At present, most air conditioners only have a single function of cooling in summer and heating in winter to adjust the indoor air temperature. Especially in summer, a large amount of heat g...

Problems solved by technology

At present, most air conditioners only have a single function of cooling in summer and heating in winter to adjust the indoor air temperature. Especially in summer, a large amount of heat generated by the air conditioner during the cooling process is discharged to the outside without use. In the atmosphere, it causes thermal pollution of outdoor air and great waste of energy

The air conditioner is only used in winter and summer, and the utilization rate is not high; at the same time, homes and offices with air conditioning also need to purchase additional water heaters to solve the problem of daily hot water in life, which increases expenses, and electric water heaters , Gas water heaters consume a lot of energy and are less safe

At present, many air conditioners with hot water heating function have emerged, but only when the air conditioner is cooling, the waste heat generated by the air conditioner is used to heat hot water. When heating water, the heat exchanger 17 cannot be used as an evaporator to meet the demand for small cooling capacity when cooling and heating hot water; when the air conditioner is heating, although the heat pump heating has the characteristics of high energy efficiency, the prior art has not The ideal technical solution realizes the function of heating hot water at the same time
