The compressor, condenser, enlargement valve, and evaporation make up the cooling unit. The refrigeration cycle is utilized to chill down inside air before recirculating it through the entire facility.
When air is moving in the proper way, the system of NRD will allow it to open thereby allowing the air to movement through. But, If your air moves in the incorrect direction, the NRD blades will fall resulting from gravity, proficiently prevent the air from passing by.

If the area temperature reaches the setpoint, the thermostat sends a signal to close the damper while in the VAV box which triggers the differential tension sensor within the duct to slow down the AHU admirer pace.
They function by using heating and cooling cycles, pivotal to sustaining wanted temperatures, and incorporate vital components like refrigerants and coils for temperature regulation.
Having said that, the amount of outdoor air coming into your making is based upon a specific share of the air-con airflow. In case the air con airflow decreases, the out of doors airflow decreases. DOAS is critical to boost indoor air quality and occupant wellness in selected purposes the place outdoor airflow is crucial.
