LSH series water source heat pump screw chiller

Gree flooded-type water source heat pump screw chiller is a unit of use groundwater as a heat source for the preparation of cold water and hot water, due to the ground water temperature is relatively stable, warm in winter and cool in summer, in winter the unit extracted heat from groundwater, get hot water for air conditioning system. in the summer, unit extract the temperature of the indoor and released into the groundwater, achieve air conditioning refrigeration purposes in summer.

Unit allow the use of cold and heat source is not limited to ground water ,can also be temperature suitable surface water, domestic sewage, industrial waste and other waste heat drain

1. Energy efficiency across the board, a multi-purpose machine

* Unit obtained the first national model of energy-saving

* Unit both produce hot water and cold water, heating and cooling for a variety of places to use; can use alone as a water heater, provide hot water Max up to 55℃, to meet the needs of various buildings for domestic hot water

2. Reliable oil return system , ensure the stable operation of units

Gree oil return system--for the flooded-type water source heat pump chiller, set the low oil level protection control, completely eliminate the possibility of compressor less oil damage .using secondary oil separator, the oil separate efficiency reach 99.97%

3. New throttling approach, balance the stability and sensitivity.

Gree original new throttle approach adopt solution of connect electronical expansion valve and hole plate in parallel to throttle, ensure stability and sensitivity of unit.

4. Flooded-type heat exchanger ,higher heat transit efficiency.

Compare with ordinary dry-type evaporator, refrigerant of flooded-type evaporator flow outside of the tube, surface of heat exchange fully touch with the refrigerant. good heat transit efficiency, improve unit EER.

5. Top quality product, beginning from basis parts and accessories.

6. Dual compressor connect in parallel system, higher comprehensive EER.

*Gree flooded dual compressor in parallel technology ,can be set to dual compressor running in parallel

*can also be set to single compressor independent running, higher efficiency when unit in part load running.

7.Waste-heat utilization, protect environment and health.

LH water-cooled screw chiller allow but not limited to ground water,it can be temperature suitable surface water, sanitary wastewater and various of waste heat discharge. effect to recycle heat energy.

8. Multiple protection function, running worry-free

Power loss phase protection, power reverse phase protection. motor overload protection, motor overheating protection. Freeze-proof protection. water switch protection. low floe protection, preventfrequent start function.system high power voltage protection. Low power voltage protection. High temperature exhaust protection. High pressure and low pressure variety protection. automatic freeze-proof function. Oil level switch protection. Safety valve protection. Sensor fault alert

Other safety measures,such as hypertonus,low unload function,compressor oil heater control,Minimum duration limit,all these efficient to improve stability of units.

9.Luxurious LCD screen,clear and convenient to check the unit running status

Have display time,temperature,Debug Parameters,fault massage,set,inquiry function.

10.Remote intelligent service center

Gree remote intelligent service center is an advanced service platform to provide fault warning, pre-warning in running, running diagnostics, running data statistics, analysis, maintenance reminders and other services. The air conditioning units running at peak performance, reduce user maintenance costs, extend the life of the unit
