It can be found on two-phase warmth pumps or any systems that has a backup heater for instance an auxiliary electric heater. ODT ensures the ability-hunger backup heater only activates when the skin temperature is too chilly.
BCU means Blower Coil Unit. BCU is often a compact variety of ground-standing air handler that use either chilled h2o or refrigerant to supply air con. BCU itself commonly doesn’t have compressor and condenser.
CWS stands for Condenser H2o Provide. CWS is usually found in the chilled h2o system layout and schematic drawings. It's also widespread to have the CWS phrase physically painted to the condenser h2o pipe to indicate the condenser drinking water movement direction with the cooling tower towards the chiller.
EA means Exhaust Air. EA is commonly present in duct layout drawings, specifically for the ventilation system. EA is often penned close to the exhaust air grille, vent or register. It is usually accompanied by an arrow pointing faraway from the exhaust air grille indicating the airflow path.
PAU means Main Air Dealing with Unit. PAU can be a style of air handling device that processed the outdoor air. It has a further layer of air filter, A much bigger cooling coil together with other more components necessary to bring in out of doors air, process it (cooling, heating, humidifying or dehumidifying) and supply it to other secondary air handing models within the developing.

1. Heating Unit: Generally features a furnace or maybe a warmth pump, which presents heat during the colder months.
On the other hand, the level of out of doors air coming into your developing is based on a certain percentage of the air con airflow. If the air-con airflow decreases, the outdoor airflow decreases. DOAS is necessary to improve indoor air quality and occupant health in particular applications in which outdoor airflow click here is vital.
The system also assists maintain air high-quality. By way of a series of exchanges, filters, and coils, HVAC models perform to supply both thermal comfort and acceptable indoor air high-quality.
