Heat pumps: By shifting warmth in between indoor and outside spaces, they offer each cooling and heating.
Contrarily, non-DX or indirect enlargement refers to tools like chillers which use chilled drinking water as the medium of warmth transfer instead of refrigerant.
TC means Thermocouple. TC is actually a form of temperature sensor consisting of two wires of different metals joined at Each individual conclude. It is actually Ordinarily Employed in fuel furnaces and incredibly hot water tanks for valve and operation controls.
The compressor is a central part inside the HVAC system, often located in out of doors units for break up systems. It pressurizes refrigerant, which plays an important role in heat Trade.
Air Handler: The indoor air managing unit has the evaporator coil, blower, air filter, and often added components. It circulates conditioned air through the setting up by way of a community of ducts.
PIU stands for Ability Induction Device. PIU is often a secondary air-con unit that is usually located close to the target cooling/heating House. It will take in air conditioned by the main air conditioning unit which include an AHU, and further cool/heat the air on the target Room temperature.
ATC stands for Automatic Temperature Management. ATC is used to indicate the temperature and humidity in particular sections/zones of the developing is quickly controlled via the air-con system.
Vents/Registers: Vents and registers are opening in partitions, floors, or ceilings exactly where conditioned air enters rooms and where return air is collected.
It unique by itself from multi-split air con systems by acquiring merely a set of refrigerant pipes. The refrigerant pipes are related by y-joints

RAF means Return Air Filter. RAF refers back to the filter inside a return read more duct or with a return grille. It really is an air filter utilized to circumvent dust from accumulating In the return duct.
Thermostat: Called the “Mind” of an HVAC system, the thermostat tells the system when to show on and off depending on its temperature configurations.
The filtered, very hot air is blown more than the evaporator coil, a percentage of your air conditioner that gets filled with liquid refrigerant. The evaporator coil absorbs the heat from the air, which turns the refrigerant into a fuel.
OAHU means Outdoor Air Handling Unit. OAHU is actually a type of air handling device that approach a hundred% out of doors air. It's yet another layer of air filter, a bigger cooling coil and various additional components necessary to usher in outdoor air, system it (cooling, heating, humidifying or dehumidifying) and provide it to other air-con units or immediately into your developing.
