Problems solved by technology

[0003] Since the existing hot water air conditioner is to add a water heater on the basis of constant speed one drag one to realize the functions of cooling, heating, hot water heating, cooling + hot water heating, it cannot realize heating + hot water heating at the same time function of
In addition, the existing hot water air conditioner uses a fixed-frequency compressor, which cannot steplessly adjust the output capacity, resulting in frequent startup of the compressor and low efficiency, thereby shortening the operating life of the compressor and wasting energy

Abstract

The invention discloses a hot water air-conditioner. An indoor heat exchanger and an outdoor heat exchanger are connected with a compressor by a first pipeline and a second pipeline selected by a four-way reversing valve; the indoor heat exchanger and the outdoor heat exchanger are connected by a third pipeline; a water-side heat exchanger is arranged on a fourth pipeline in parallel connection with the second pipeline. The invention also comprises a fifth pipeline and a sixth pipeline with one end both connected with the third pipeline and the other end respectively connected with one side of the water-side heat exchanger in the fourth pipeline; a first control valve on the sixth pipeline; a second control valve arranged on the second pipeline and between two node of the fourth pipeline and the second pipeline; a third control valve arranged on the fourth pipeline and between first nodes of the fourth pipeline and the second pipeline and the water-side heat exchanger; a fourth control valve on the fifth pipeline; a fifth control valve arranged on the fourth pipeline and between second nodes of the fourth pipeline and the second pipeline and nodes of the fourth pipeline and the fifth pipeline. The invention achieves the functions of cooling, heating, water heating, cooling + water heating and heating + water heating.

Description

technical field [0001] The present invention relates to a compression machine, device or system with a reversible cycle, in particular to a hot water air conditioner. Background technique [0002] The high-temperature exhaust gas generated during the use of air conditioners can be used to make hot water, which is not only conducive to energy saving, but also conducive to reducing the greenhouse effect. For this reason, the air conditioner with water heater has appeared on the market, is to increase water heater on the basis of air conditioner, thereby realizes the function of heating water on the basis of air conditioner. [0003] Since the existing hot water air conditioner is to add a water heater on the basis of constant speed one drag one to realize the functions of cooling, heating, hot water heating, cooling + hot water heating, it cannot realize heating + hot water heating at the same time function. In addition, the existing hot water air conditioner uses a fixed-fr...
