High Efficiency LTMLH Series Flooded Type Screw Compressor Ground Source Heat Pump; Water to Water Heat Pump

Competitive Advantages:

Flooded evaporator compared with dry evaporator COP increased 1.5. The latest threads and efficient heat exchange tube make heat transfer coefficient over normal heat exchange tubes of 1.3 times. It Can take ground water, surface water (rivers, lakes, sea) and soil as air conditioning heating or cooling source for the floor radiant, radiator, fan coil units and other end of the form of heating, cooling. Free living hot water if asked.

Features:

1)5: 6 tooth gear design with the world famous twin-screw compressor, small vibration, low failure rate, advanced energy control method which can achieve a paragraph or unwarranted energy regulation; injection compression, noise seal.

2)Control device using the world famous, PID regulation, completely eliminate the stuck rotor or motor overheating; high temperature and low pressure exhaust temperature monitor and control access to water, water, antifreeze, water temperature and other multi-protection, to ensure the safe operation of generating units; large-screen color touch screen.

3)Optimal design can improve a wider range of cooling capacity. Part load performance is good. New electronic throttle device, achieve null process control. Part of the load, the double-press alternately run and longer life.

4)Application of places: hotels, restaurants, hospitals, office buildings, theaters, stadiums, residential quarters, textile, food, medicine, metallurgy, chemicals and boiler works.
