DHU means Dehumidified Air Managing Device. DHU is designed to eliminate water vapor or dehumidify considerably more successfully than typical AHU. It can deploy components such as desiccant to improve the dehumidification capability of the system.
VRV means Variable Refrigerant Quantity. The VRV is patented by Daikin which refers into a kind of air con system that distribute refrigerant from a single out of doors unit to a number of indoor models.
ECM means Electronically Commutated Motor. ECM is often called DC brushless motor. It's a large-successful motor that typically found in FCU, ceiling ducted device and various modest-ability air conditioners. ECM includes a motor effectiveness course rating of at the very least IE3 and higher than.
EER stands for Electrical power Efficiency Ratio. EER is an additional common measurement for the Strength efficiency of air conditioners. EER is calculated by dividing the ability in BTU by the power input in W.
Ductwork: The ducts include a community of passages that distribute conditioned air through the developing and return air on the system.
CHWS means Chilled Water Provide. CHWS is often present in the chilled drinking water system structure and schematic drawings.
