Ground source heat pump Feature:
1. Apply for imported compressor and famous accessories, reasonable
match makes unit performance perfect.
2. Apply unique dimensional structure design, smaller installation
size and no affect for indoor decoration appearance.
3. Unit can be used independently or in modular mode, each unit can
be independent charged for easy check computation.
4. Apply for advanced microcomputer control for easy understanding
for unit status.
5. High-efficient sound absorption &heating insulating material
and double layered vibration damped on design, it features
low-noise and bring enjoyment for security.
6. Each maintain, only to demount maintenance plate to repair, it
features modular design, other units still can normally operate
during maintenance.
Internal porduct accessores:
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 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
