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
