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
