Porduct 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.
Installation different situations:
The ground source heat pump can also be called a soil source. It is
buried in underground soil with high-polyethylene U-shaped pipe
filled with water and antifreeze. The two ends of the pipe are
connected to the evaporator in the ground source heat pump. Water
and antifreeze are The circulation in the pipelines will
continuously transfer the heat in the soil to domestic water.
Ground source heat pump 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
