VVR means Variable Volume Ratio. VVR is really a technology by Daikin. It permits the chiller’s compressor to regulate the compression ratio mechanically when it senses the amount of elevate needed in any provided instant. It improve the performance with the chiller and will save Electrical power.

MFD means Motorized Fireplace Damper. MFD is really a form of damper that is the two motorized and immune to hearth. It employs an actuator to automatically/remotely open up and close. Its fire resistance is normally two hrs. MFD is required each time a duct penetrates by way of a fire compartment wall.

Some HVAC relays required 24VDC of power supply. Meaning it requires 24V of direct present-day electrical power. If the incoming electric power supply is 240VAC (240V alternating present), then a 240VAC to 24VDC transformer is needed for the ability conversion.

The air handling unit will help sustain Every single space's clean environment by delivering an correct volume of cleanse air to each area at the proper temperature and humidity.

The HVAC system’s air-con part operates by drawing in contemporary air from outside in the system right into a combine air chamber for mixing With all the space return air.

PIU means Energy Induction Unit. PIU website can be a secondary air con device that is usually Situated near the concentrate on cooling/heating Place. It will require in air conditioned by the key air-con device such as an AHU, and even more cool/heat the air to your target Room temperature.

VSAT means Vapor Saturation Temperature. VSAT is The purpose in which liquid refrigerant start out turning into vapor/fuel. It really is also called the refrigerant evaporating temperature. VSAT can be used to determine if an evaporator is working properly.

NRD means Non Return Damper. NRD is often a form of damper which allows air to move in a single direction only. It make the most of the force of gravity and content weight to close.

Air Conditioning: This element cools the indoor air all through warmer months, commonly with here the usage of air conditioners or heat pumps.

Sellers can response queries, enable you to locate the proper items for your home, and repair service your system.

This article and all articles over the Petro Dwelling Expert services Internet site are actually permitted by our crew of house service industry experts.

This bring about the refrigerant tension entering the compressor to get as well very low. If this persist, the compressor may well freeze. Therefore, the LPC will shut from the system to safeguard the compressor.

This induce the refrigerant stress getting into the compressor to generally be far too low. If this persist, the compressor may freeze. Therefore, the LPS will shut from the system to shield the compressor.

Air-con is yet another crucial ingredient of HVAC systems, specifically in hotter climates. Air conditioners function by eliminating heat and dampness from the indoor air, supplying amazing and dehumidified air. This method is accomplished via a refrigeration cycle that involves compressing and expanding refrigerant to absorb and release heat.
