Throughout cooling cycles, heat air from the inside is moved above the evaporatorcoil, where by the refrigerant absorbs heat, efficiently cooling the air. Within a gaseous point out, the refrigerant is pumped exterior the condenser coil, releasing its warmth and altering to the liquid.

BDD stands for Backdraft Damper. BDD is utilized to make certain air flows in one course. It prohibit air from flowing inside the reverse way through the use of a mechanism to automatically near the damper in the event the air is flowing in the wrong course.

HX stands for Warmth Exchanger. HX refers to the evaporator, condenser or even the cooling coil of an air conditioner or a chiller.

DHU means Dehumidified Air Dealing with Device. DHU is designed to eliminate h2o vapor or dehumidify much more efficiently than traditional AHU. It may deploy components such as desiccant to Increase the dehumidification functionality of your system.

BCU stands for Blower Coil Unit. BCU is usually a compact sort of flooring-standing air handler that use either chilled drinking water or refrigerant to supply air-con. BCU alone normally doesn’t have compressor and condenser.

Air flow is a vital drive in all HVAC units. Initial, There's a supply of contemporary air intake both with the exteriors or throughout the setting up. From listed here, the process of ventilation can occur in a single of two means:

EER means Electricity Performance Ratio. EER is yet another universal measurement for your Strength efficiency of air conditioners. EER is calculated by dividing the capability in BTU by the ability input in W.
