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 high efficiency plate heat exchanger, high heat transfer
efficiency, small footprint, and has a small heat dissipation
characteristics, in the case of water quality is not very bad, the
use of plate heat exchanger is the best choic
Ground source heat pump feature :
1. Adopt world famous brand compressor.
2. High purity refrigerant: R410a/R407C, to make sure high COP.
3. Optimized system design: R410a/R407C system with accurate
capillary tube or electronic expansion valve, achieving stable
operation and high COP in wide ambient temperature range.
4. Big heat exchangers: big hydrophilic fin-tube heat exchanger,
big titanium coil heat exchanger, (maybe the biggest one in China),
to make sure high COP in wide ambient temperature range.
5. Big and strong case: allowing built-in big heat exchangers, and
reducing vibration and noise.
6. Advanced control: the quick-mind microchip LCD controller (Carel
controller is optional) provides extremely convenient control on
the heat pump.
7. Comprehensive protection: the heat pump is protected fully,
including water flow, water temperature, compressor pressure and
temperature, temperature for heat exchanger, and anti-freezing for
heat exchanger and so on.
8. Quiet: using the high-efficiency, low noise rotary or scroll
compressor, low noise fan.
Ground source heat pump working principle
The difference between the water source heat pump and the air
source is that the low-temperature and low-pressure liquid
refrigerant exchanges heat with the water in the water/ground
source pipeline in the evaporator, absorbs the heat Q1 in the water
and evaporates into a low-temperature and low-pressure gaseous
state, and then enters into a vaporized state. Compressor works
through compressor W, is compressed into high temperature and high
pressure gas, then enters condenser, exchanges heat with indoor
water, transfers heat Q2 to indoor water, and the refrigerant
condenses into high temperature and high pressure liquid, and then
enters the expansion valve. With throttling, the refrigerant
becomes a low-temperature and low-pressure liquid, and the
throttling refrigerant enters the evaporator and undergoes heat
exchange and evaporation, thereby realizing inverse carnot
The whole process, also Q2=Q1+W in this process
