Enter more and more homes and offices. At present, most air-conditioning units only have the single function of cooling in summer and heating in winter to adjust the indoor air temperature. Especially in summer, the large amount ...

AI Technical Summary

Problems solved by technology

At present, most air-conditioning units only have the 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 air-conditioning units in 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 existing air-conditioning units are only used in winter and summer, and are idle in spring and autumn, and the utilization rate is not high; at the same time, homes and offices with air-conditioning need to purchase additional water heaters to solve the problem of daily hot water in life , increased expenses, and electric water heaters, gas water heaters consume a lot of energy and are less safe

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

The multi-connected heat recovery air-conditioning unit in the prior art cannot produce hot water, and the multi-connected heat pump hot water air-conditioning unit cannot simultaneously cool and heat. Air-conditioning heat pump water heater unit providing hot water
