Inside a basement carpark, multiple CO2 sensors are set up to measure the CO2 level. However, just one fan serves that spot. A DDC controller connects multiple CO2 sensors, analyse them and deliver a single signal on the admirer to manage the start/end.

Contrarily, non-DX or indirect expansion refers to tools like chillers which use chilled drinking water given that the medium of heat transfer as opposed to refrigerant.

The air is filtered by pleated paper filters referred to as significant performance particulate air (HEPA) filters which, dependent on the classification of the rooms, can be found either within the air dealing with unit or exactly where the air enters Each and every home.

HVAC stands for Heating, Air flow, and Air Conditioning. These systems are designed to regulate the temperature, humidity, and air high-quality in indoor spaces. An successful HVAC system ensures that your own home or Business continues to be at ease regardless of the climate outside.

If the adverse tension is important, the exhaust system received’t get the job done any more. As a result, MUA is necessary to make sure the room won’t be became a vacuum space plus the exhaust system can continually perform.

PIU stands for Ability Induction Unit. PIU is a secondary air con device that is often Found near the concentrate on cooling/heating Place. It takes in air conditioned by the principal air-con device such as an AHU, and more neat/warmth the air on the concentrate on space temperature.

EER means Strength Effectiveness Ratio. EER is an additional common measurement for that Electricity performance of air conditioners. EER is get more info calculated by dividing the potential in BTU by the facility enter in W.

Vents/Registers: Vents and registers are opening in walls, flooring, or ceilings the place conditioned air enters rooms and where by return air is gathered.
