DX stands for Immediate Expansion. DX refers to air conditioners that use refrigerant as the medium of heat transfer to chill the air. Samples of DX systems include break up air conditioners, multi-break up air conditioners, and VRF/VRV systems.
IU stands for Induction Unit. IU can be a secondary air conditioning unit that is often located close to the target cooling/heating Place. It requires in air conditioned by the key air conditioning device for instance an AHU, and further cool/warmth the air to the concentrate on Area temperature.
2. Local weather: Your local local climate performs a vital part in figuring out the type of HVAC system that should be most effective. One example is, warmth pumps are simpler in milder climates, while furnaces are greater suited for colder regions.

The compressor compresses the warm air into scaled-down spaces, allowing it to get cooled speedily. click here Right after cooling, the air passes via One more filter to remove dust and dirt ahead of returning to the residing House.
VFD means Variable Frequency Push. VFD is applied to regulate the motor velocity of AHU and pump. It lets the system to manipulate the frequency of the electric power provided on the motor therefore making it possible for the more info motor to change its rotational speed.
The chiller capacity is count on the full cooling load for The entire AHU systems. the kind of chiller depends on the Cooling capacity . By way of example, if the cooling capability range to seven hundred-2800 kW, we normally pick Screw / Centrifugal sort of Compressor Drinking water cooled Chiller.
RPM means Revolution for each Minute. RPM refers back to the rotational velocity of lovers and pumps. For example, a pump contains a move rate of two hundred GPM at 1450 RPM. When the RPM increases, the circulation level will increase. According to the pump affinity law, RPM is straight proportional to stream level.
