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

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 Advantage:
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.
