Brief Introduction of Full-liquid Type Ground Source Heat Pump Unit

It is developed by Shuangyi group who bring in advanced technology from European and American countries. It use normal temperature soil or underground water and has the characteristic of relatively stable temperature. It is widely used in hotel, shopping mall, office, exhibition hall, airport, gymnasium and other public facilities. It has advantages of high efficiency, low noise, rational construction,user-friendly control, operation Security, easy installation and maintenance, etc.

Product Components and Technical Features of Full-liquid Type Ground Source Heat Pump Unit

The compressor
Compressor is full-liquid special compressor and equipped with motor overheating, oil level, oil pressure difference, exhaust stability and other protections to ensure the safe operation.
Condenser
High efficiency heat exchange tube is used to make the efficiency of secondary oil in the condenser, making the unit more beautiful, the structure more concise and oil separation effect is better.
Evaporator
The efficient evaporator is adopted. Compared with the traditional dry evaporator, the advantages are:
The ratio of energy input to energy output is improved.
Maintenance is more convenient and more reliable
Capacity is bigger, investment is less
There is less demand for underground water
Oil control technology of the unit
The unit is equipped with efficient internal secondary oil, reliable ejection pump oil return system, stable refrigerant liquid level control system and automatic pull oil program,etc.
Priming pump principle
By using the negative pressure generated in the larynx of the ejector, the oil of the oil-rich layer of the evaporator is directed to the throat position and the high pressure gaseous cold medium, and then enters the suction end of the compressor
