Three-combined supply system capable of achieving heat recovery

Abstract

The invention discloses a three-combined supply system capable of achieving heat recovery. The three-combined supply system capable of achieving heat recovery comprises a first compressor, a first four-way valve, a first gas-liquid separator, a first evaporator, a first stop valve, a second stop valve, a first throttling component, a third stop valve, a second throttling component, a first economizer, a first heat exchanger, a hot water tank and a first water pump. The first compressor is connected with the first four-way valve. The first four-way valve is connected with the first stop valve. The first stop valve is connected with the first heat exchanger. The first heat exchanger is connected with the first economizer. The first heat exchanger is also connected with the hot water tank. The first economizer is connected with the first throttling component. The first throttling component is connected with the first evaporator. The first evaporator is connected with the first four-way valve. The first four-way valve is connected with the gas-liquid separator. The first gas-liquid separator is connected with the first compressor. According to the three-combined supply system capable of achieving heat recovery, multi-function work such as heat recovery can be achieved; and in addition, the heat exchange speed is high, the performance is stable, the utilization rate is high, and the application range is wide.

Description

technical field [0001] The invention relates to the field of air conditioning systems, in particular to a triple supply system capable of realizing heat recovery. Background technique [0002] Most of the existing heat pump products for air conditioners are mainly used for cooling or heating. When the air conditioner is cooling or heating, it will discharge a large amount of heat or cold air to the outside; When hot water is used, a large amount of cold air will be emitted to the outside; therefore, most air-conditioning heat pump products at this stage not only do not have comprehensive utilization of energy, but also have single functions. [0003] In the existing triple supply system, the heat exchange mode at the end of the heat exchanger can be divided into two categories: [0004] Fluorine cycle mode: For example, "A Triple Heat Supply Pump System" disclosed in the Chinese invention patent application with publication number CN103307805A, the end uses fluorine cycle f...
