Meeting MD70D ground water source heat pump electric water heater for domestic hot water radiator heating cooling

Technology Specification

Meeting MD70D ground water source heat pump electric water heater for domestic hot water radiator heating cooling

Remarks:Initial/final water temperature of load side :15℃/55℃,Initial/outlet water temperature of source side, 15℃/ 10℃

Porduct 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.

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.

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
