Heat pump hot-water multi-unit air conditioner

Abstract

The present invention provides a heatpump heat water multiple air condition not only meeting the needs of cool or heat to the user, but als meeting needs of hot water, the heatpump heat water multiple air condition includes an indoor heat interchanger, an outdoor heat interchanger, a heatpump water tank and a four-way valve corresponding to the outdoor heat interchanger and the heatpump water tank, the inlet of the four-way valve and the outlet of the compressor are jointed together in a high pressure windpipe, the outlet of the four-way valve is connected to the inlet of the compressor, the normal opening end of the first four-way valve is connected to the outdoor heat interchanger, the normal closing end of the first four-way valve is connected to the inlet of the compressor, the normal opening end of the second four-way valve is connected to the heatpump water tank, the normal closing end of the second four-way valve is connected to the outlet of the second four-way valve by capillary. The invention makes the multiple air condition prepare hot water in the course of cooling or heating by controlling flow direction of each four-way valve.

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
