Heat pump hot-water multi-unit air conditioner

Abstract

The present invention provides a heat pump hot water multi-connected air conditioner that can meet the cooling or heating needs of air conditioner users and can also produce hot water. The heat pump hot water multi-connected air conditioner includes an indoor heat exchanger and an outdoor heat exchanger. , a heat pump water tank, and a four-way valve corresponding to the outdoor heat exchanger and the heat pump water tank. The air inlet of the four-way valve and the exhaust port of the compressor are connected to a high-pressure air pipe together. The outlet of the valve is connected to the suction port of the compressor, the normally open port of the first four-way valve is connected to the outdoor heat exchanger, the normally closed port of the first four-way valve is connected to the indoor heat exchanger, the second four-way valve is normally The open port is connected with the heat pump water tank, and the normally closed port of the second four-way valve is connected with the outlet of the second four-way valve through a capillary tube. In the present invention, by controlling the flow direction of each four-way valve, the multi-connected unit can heat water while cooling or heating.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a heat pump hot water multi-connected air conditioner capable of recovering energy and having the function of heating hot water. Background technique [0002] With the development of the economy and the improvement of people's living standards, air-conditioning units have better and better market application prospects, and gradually enter more and more homes and offices. At present, most air conditioners only have the function of cooling in summer and heating in winter to adjust the indoor air. Especially in summer, a large amount of heat generated by the air conditioner in the cooling process is discharged to the outdoor atmosphere uselessly. In the process, it causes thermal pollution of outdoor air and a great waste of energy. Generally, air conditioners are only used in winter and summer, and the utilization rate is not high. At the same time, homes and offices with air conditioners need...

Problems solved by technology

At present, most air conditioners only have the function of cooling in summer and heating in winter to adjust the indoor air. Especially in summer, a large amount of heat generated by the air conditioner in the cooling process is discharged to the outdoor atmosphere uselessly. In the process, it causes thermal pollution of outdoor air and a great waste of energy. Generally, air conditioners are only used in winter and summer, and the utilization rate is not high. At the same time, homes and offices with air conditioners need to purchase additional water heaters to solve life The problem of daily water use in China increases the expenditure, and electric water heaters and gas water heaters consume a lot of energy and are less safe.

At present, there are many air conditioners with the function of making hot water, but most of them can only use the waste heat generated by the air conditioner to heat hot water when the air conditioner is cooling. When the air conditioner is heating, it cannot be used as a water heater. use
