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
