Ground source heat pump 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.
Internal porduct accessores:
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
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
