OT stands for Operating Theatre. OT is in which Physicians and surgeons perform surgical Procedure to people in a medical center. It is a Specific room that needs extensive treatment during the design on the air con system.
It distinctive by itself from multi-break up air-con systems by having only a set of refrigerant pipes. The refrigerant pipes are linked by y-joints.
A lack of ductwork can make ductless systems hugely economical, since it’s believed 20% or even more of conditioned air is usually dropped through leaky ducts or inadequately insulated ductwork.
All through mechanical ventilation, as soon as the air is introduced in, it's taken in by an air handling unit the place the entire process of manual air flow starts. The air is filtered to remove dirt, allergens, dust and other particles. From there, it's released back out to either offer heated or cooled consolation.
Warmth pumps can also be utilized to a neat a house, reversing the flow of refrigerant it utilizes to heat residences by absorbing warmth within the indoor air and releasing it with the outside unit.
ECM stands for Electronically Commutated Motor. ECM is often known as DC brushless motor. It is just a higher-effective motor that commonly found in FCU, ceiling ducted device and various small-capacity air conditioners. ECM incorporates a motor performance course score of not less than IE3 and previously mentioned.
It can be any type like finned-tube heat exchanger which is often found in residential break up air conditioners or shell-and-tube heat exchanger which is far more usually found in h2o-cooled chiller.
NRD means Non Return Damper. NRD is really a form of damper that allows air to maneuver in a single course only. It utilize the force of gravity and content pounds to close.
Volume of air transfer to each area Regulate by VAV which is known as variable air volume Found at the returned duct.
Your Qualified technician will set up your system, plus they’ll be there to assist with things like upkeep and troubleshooting When they could be necessary.
If more info the room temperature reaches the setpoint, the thermostat sends a signal to shut the damper while in the VAV box which triggers the differential strain sensor from the duct to slow down the AHU supporter speed.
They function by employing heating and cooling cycles, pivotal to keeping desired temperatures, and incorporate essential components which include refrigerants and coils for temperature regulation.
OA means Out of doors Air. OA is often present in duct structure drawings, especially for the ventilation system. OA is often composed beside the out of doors air grille, vent or register. It is usually accompanied by an arrow pointing toward the outdoor air grille indicating the airflow direction.
AC means Air Conditioner. AC is usually a generic time here period used to indicate an air conditioner, regardless of the type. The air conditioner is often AHU, FCU or almost every other sort that provides airflow and air con to a place.
