Cooling capacity: 150~1900kw.The modular air-cooled chilled water (heat pump) unit is an integrated central air-conditioning unit that uses air as the cold and heat source and water as the cooling and heating medium. The unit is divided into single-cooled and heat-pump types. Low running noise. Because of its equipment investment flexibility and engineering installation simplicity, it has always been a good choice for central air-conditioning systems, and is widely used in villas, hotels, hospitals, office buildings, entertainment venues, theaters and other commercial, industrial and civil buildings.Westinghouse Kangda's new generation of modular air-cooled chilled water (heat pump) units is a high-efficiency environmentally friendly air-conditioning unit that Westinghouse Kangda inherits many years of design and manufacturing experience in air-cooled heat pumps. National energy-saving standards, the unit uses the internationally recognized environmentally friendly refrigerant R410A, compared to ordinary units with less refrigerant charge, higher energy efficiency ratio, lower operating costs, environmentally friendly and so on.It adopts internationally recognized environmentally friendly refrigerant R410A, which has stable performance, non-toxicity, and no damage to the ozone layer. ODP (Ozone Depletion Potential) is 0, and there is no risk of being replaced. ) More powerful and reduce ineffective wear and tear.The high-precision electronic expansion valve is used to realize the PID refrigerant flow adjustment of the unit, which has the characteristics of fast response speed and high adjustment accuracy, and realizes stable and reliable operation within the full operating range of the unit.The unit adopts an international brand fully-enclosed scroll compressor. The compressor uses a low-pressure cavity design to ensure that the motor always maintains efficient and stable operation. The high-temperature and high-pressure refrigerant vapor is directly discharged from the compressor, reducing pressure and heat energy loss, and improving compressor efficiency.The new high-efficiency spiral baffle plate shell tube heat exchanger uses a distributor to separate liquids to ensure uniform distribution of refrigerant at the tube side, maximizes the use of heat exchange area and improves heat exchange performance by 10%. Adopting full welding manufacturing process, high compressive strength, no risk of leakage, dirt resistance, blocking resistance, freezing resistance, high reliability.
