Technology Specification

Porduct Advantage:

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

Internal porduct accessories

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.

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

QC

1. Complying with ISO standard. Quality Ensured.

2. Complete Inspection for each unit before out of factory, covering water system and electricity detection and testing, ensuring 100% right product before shipment.

3. Strict quality control during production. We have liquid soap detection, halogen detection, electrical detection and water-soaking detection during production to avoid gas leakage and electrical problems .

4. Full inspection on bigger parts such as compressors, condensers, evaporators, expansion valves, flow switches, controllers etc.. Selection inspection for small parts such as sensors, pressure switches etc..

5. Well noise control by using mute cotton for casing plates and soft rubber feet for floating compressors, some of the models use compressor isolation shields.

6. Well insulated with insulated cotton for every pipe and parts, include compressor, dryer filter and each pipes.

7. We have passed TUV and SGS inspections. We have CE, RoHs, IEC, CCC, CB certificates for most of our products. Some of our products have en14511 test, en14825 test.
