Gree permanent magnet synchronous inverter centrifugal chillers

Gree LH series screw type water chillers

1. Full liquid evaporation method

Full-liquid evaporator, evaporator in the distribution of uniform refrigerant, the temperature field optimization, improve the unit's evaporation temperature, heat exchanger with high efficiency heat transfer tube to further reduce the heat transfer resistance, high heat transfer efficiency; Apply special screw compressor, to enhance the unit's cooling capacity and energy efficiency, win energy-saving certification.

2. New Throttle

Automatic calculation of energy efficiency ratio, rapid adjustment of the actual value, on-demand output optimization control logic; electronic expansion valve to adjust the cooling flow and evaporator level changes, partial load efficiency, wide operating range.

3. High efficiency oil separator

Gree patented oil separator, using cyclone, inertial collision, natural settlement, adsorption separation and other comprehensive means to improve oil efficiency, energy efficiency and reliability higher.

4. The ejector assists oil-return 

The ejector is an important auxiliary oil return device, and the ejection effect affects the reliability of the operation. According to different ejection methods, the model of ejection is established and the numerical simulation is carried out. 

When the unit in the bad oil return conditions, the ejector will automatically open, so that the unit back to oil and reliable.
