Problems solved by technology

[0003] 1. When defrosting the heat pump system, it will refrigerate and cool the heated hot water in the water storage tank, thus wasting energy;
[0004] 2. When the sensor of the water storage tank has a temperature deviation, the exhaust temperature is often higher than the normal value, and the exhaust temperature of the compressor is too high for a long time, which will cause damage to the compressor and the four-way valve

Embodiment Construction

[0025] The specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] Such as Figure 1-Figure 2 The shown heat pump system 1 includes a compressor 2 , a four-way valve 41 , a first condenser 31 , a second condenser 32 , a throttling device 5 and an evaporator 6 . The refrigerant circulates among the compressor 2, the four-way valve 41, the second four-way valve 42, the first condenser 31, the second condenser 32, the throttling device 5, and the evaporator 6. The connections are made through pipelines, preferably copper pipes, and the connection relationship between the above-mentioned components will be described in detail below.

[0027] The compressor 2 has a high-pressure discharge port 22 and a low-pressure suction port 21 . The refrigerant enters the compressor 2 from the low-pressure suction port 21 and is discharged from the high-pressure discharge port 22 after being compressed by t...

Abstract

The invention discloses an energy-saving heat pump system. The energy-saving heat pump system comprises a compressor, a four-way valve, a first condenser, a second condenser, a throttling device and an evaporator, wherein the first condenser is connected between the compressor and the four-way valve in series. The energy-saving heat pump system can work in a heating mode or a defrosting mode as needed. The energy-saving heat pump system has the advantages that energy saving effect is good and the compressor and the four-way valve are effectively protected.

Description

technical field [0001] The invention relates to a heat pump system. Background technique [0002] The heat pump system in the prior art mainly has the following defects: [0003] 1. When defrosting the heat pump system, it will refrigerate and cool the heated hot water in the water storage tank, thus wasting energy; [0004] 2. When the sensor of the water storage tank has a temperature deviation, the exhaust temperature is often higher than the normal value, and the exhaust temperature of the compressor is too high for a long time, which will cause damage to the compressor and the four-way valve. Contents of the invention [0005] The present invention aims to solve the technical problems mentioned above, and provides a heat pump system with good energy saving effect and effective protection of compressors and four-way valves. [0006] To achieve the above-mentioned purpose, the present invention is achieved through the following technical solutions: [0007] An energy...
