Air cooled screw chiller(heat pump)unit

The air-cooled screw heat pump unit is a central air-conditioning unit that uses air as a cooling / heating source and water as a carrier. As an integrated device for both cooling and heating, the air-cooled heat pump omits the cooling side cooling tower, water pump, Boiler and corresponding piping system and other auxiliary parts. The system has a simple structure, saves installation space, is easy to maintain and manage, and is highly efficient and energy-saving. It is especially suitable for areas with insufficient water resources. The air-cooled screw heat pump unit is usually a centralized, semi-centralized central air-conditioning system composed of terminal units such as fan coils and air-conditioning boxes. It has the advantages of flexible layout and various control methods. The air-cooled screw heat pump unit has a large single-unit capacity and is particularly suitable. For shopping malls, hospitals, apartments, factories, office buildings and other occasions.

Air cooled screw chiller(heat pump)unit Details

◆ Adopting "W" type condenser, high-efficiency internally threaded copper tube and ultra-thin aluminum sheet are tightly combined through mechanical expansion tube, with good heat transfer effect, and double efficient economic circuit design to improve refrigeration efficiency.

◆ Using the latest high-efficiency screw-type refrigeration compressor, reliable and stable operation; low vibration and low noise; strong adaptability to various harsh conditions of air-cooled heat pumps; simple maintenance; high operating efficiency.
◆ The unit's energy is intelligently adjusted by PID according to the load condition, so that the running capacity is consistent with the actual load, so as to improve the working efficiency of the press and reduce power consumption.
◆ Adopt self-adjusting intelligent defrost mode, which is accurate and effective to avoid heat consumption.
◆ Microcomputer control, easy operation and more reliable operation. · The unit uses a fan with low speed, large air volume and low noise. · The compressor uses a sound insulation cover attached with sound absorption cotton to isolate the noise.
◆ Using world-class brand valves to ensure product grade and quality.
The unit is equipped with multiple protections such as high and low pressure, antifreeze, oil temperature, oil level, overload, internal overheating, under-phase and reverse phase, etc. to ensure the safe operation of the unit.
◆ Large cooling capacity unit adopts multi-compressor system design, small starting current, excellent standby function and excellent partial load performance.
◆ The unit can operate normally between -15 ° C and 48 ° C.
◆ The units are tested in accordance with national standards or contract requirements before leaving the factory. All of them pass the test run to ensure a good condition and all indicators meet or exceed the standard.
◆ The cooling capacity of a single module is from 100kW to 550kW, which can realize multi-module combination, which is more suitable for clubs, shopping malls, hospitals, hotels, apartments, factories, office buildings and other occasions.
