AHU means Air Handling Device. AHU is a large-capability, customizable air conditioner that product of an air filter, a cooling coil and also a blower supporter. It usually runs chilled h2o via its cooling coil to offer cooling. Study the basics of AHU below.
TC means Thermocouple. TC is often a variety of temperature sensor consisting of two wires of various metals joined at Every single finish. It truly is Ordinarily used in gasoline furnaces and hot h2o tanks for valve and Procedure controls.
In essence, the objective of an HVAC system goes further than simply controlling temperature; it encompasses making a balanced indoor local climate that aligns with human ease and comfort and health and fitness needs.
If the destructive force is significant, the exhaust system received’t do the job any longer. Hence, MUA is needed to ensure the space received’t be was a vacuum Room and also the exhaust system can repeatedly perform.
Have you ever at any time seen the big air con units that are usually placed on the best of condominium blocks or offices? These are (the seen Element of) probably the most are commonly made use of HVAC systems.
