WG means H2o Gauge. WG is a component in the measurement device for the force of fan and pump. IN.WG which means inch h2o gauge will be the Imperial device for stress. As an example, ducts are Usually designed with 0.one in.wg of stress decline per one hundred ft of duct length.
MFD stands for Motorized Hearth Damper. MFD can be a sort of damper which is the two motorized and immune to hearth. It makes use of an actuator to automatically/remotely open up and shut. Its fire resistance is often two hrs. MFD is needed whenever a duct penetrates by way of a hearth compartment wall.
Coils are crucial in this method. The evaporator coil Within the air handler or furnace facilitates warmth absorption if the refrigerant evaporates.
The compressor is often a central part inside the HVAC system, typically found in outdoor models for split systems. It pressurizes refrigerant, which plays a vital position in heat Trade.
