Machine internal configuration :

1 compressor :
The world-famous Copeland Flexible Scroll Compressor has functions such as low wear resistance, long service life, over-current protection, phase loss protection, over-the-counter protection, strong liquid-impact resistance, and high and low voltage protection. Copeland compressor built-in pressure relief valve in the body can automatically relieve pressure when the high pressure is too high

2 Electronic expansion valve:
The introduction of the latest Japanese technology in conjunction with the company's control system has led to the development of a unique electronic expansion valve control method and the use of digital technology control to control the working fluid to achieve the best flow velocity effect, thereby increasing the COP value.

3 Condenstion heat exchanger :

In combination with the United States and the United States outside the threaded pipe technology, successfully created a "spring" spiral tube new structure condenser. Better heat transfer, faster heat transfer, and higher efficiency, minimize fouling, extend heat pump life and reduce maintenance

4 Electronic control system :

With powerful engineering supporting control functions , it can control circulating water pump, make-up water , return water, water supply , electric heating , PID automatic defrosting, etc., making the control easier. According to the needs of different projects, it can set various parameters by itself and realize various water supply schemes . The entire system can be automated without special care.

5 Evaporation heat exchanger :
The use of hydrophilic membrane aluminum foil, even after long-term use The use of a hydrophilic layer also does not result in oxidative detachment. this The evaporator has a special advantage: Excellent skis performance The more you can reduce the wind resistance, so that the condensate drains out quickly
outer. Internally-threaded copper tube and corrugated aluminum foil structure   High evaporator efficiency.

Air source heat pump working principle

 According to the principle of reverse Carnot cycle, the low-temperature and low-pressure liquid refrigerant

exchanges heat with the surrounding air in the evaporator, absorbs the heat Q1 in the air and evaporates

into a low-temperature and low-pressure gas state, the temperature of the refrigerant does not change

during evaporation, and the low-temperature and low-pressure gas refrigerant After entering  the 

compressor, the compressor is used to do work W. It is compressed into high-temperature and

high-pressure gas. Then it enters the condenser. In the condenser, it exchanges heat with indoor water.

Part of the heat Q2 of the high-temperature and high-pressure gaseous refrigerant is absorbed by the water.

As the temperature rises, the refrigerant radiates heat and condenses and turns into a high-temperature, 

high-pressure liquid. During the condensation, the temperature of the refrigerant is constant and then enters the

expansion valve for throttling. Throttling is a process of rapid cooling, and the refrigerant turns into a

low-temperature and low-pressure liquid. This process is just like Contrary to the situation in the

compressor, the refrigerant after throttling enters into the evaporator for heat exchange, thereby realizing

the entire process of reverse Carnot. This cycle is continuous, and the air source heat pump can work

continuously and keep the water temperature constant. Increased

 So Q2=Q1+W in this process
