Components of an HVAC Split Unit

An HVAC split unit consists of two major components: the indoor unit and the outdoor unit. These components work together to provide efficient heating and cooling for facilities.

The indoor unit, also known as the evaporator coil or air handler, is typically located inside the building. It contains a blower fan that circulates air through the system. The evaporator coil cools or heats the air depending on whether it’s in cooling or heating mode.

On the other hand, the outdoor unit, also called the condensing unit, is usually placed outside. It houses important parts such as a compressor and a condenser coil. The compressor pumps refrigerant between these two coils, changing its state from gas to liquid and vice versa.

In addition to these main components, an HVAC split unit may include other elements like filters to improve indoor air quality and thermostats for temperature control. Some units also come with additional features such as dehumidifiers or heat recovery systems.

Understanding how each component works together allows facility managers to properly maintain their HVAC split units and ensure optimal performance all year round.

2. Ceiling Cassette Split Units: Ideal for larger spaces, ceiling cassette split units are installed in ceilings and distribute air evenly throughout the room. They have multiple vents that can be adjusted to direct airflow where it is needed.

3. Floor-mounted Split Units: These units are placed near the floor level and work well when there is limited wall space available for installation. They offer efficient heating and cooling solutions while also functioning as dehumidifiers.

4. Ducted Split Units: Ducted split units are hidden within ceilings or walls, with only supply grilles visible in the rooms being cooled or heated. This type of system provides centralized air distribution and is suitable for larger buildings with multiple rooms.

5. Multi-split Systems: Multi-split systems consist of one outdoor compressor unit connected to multiple indoor units, allowing independent temperature control in different areas of a facility.

Each type has its own advantages depending on factors such as space availability, desired cooling/heating capacity, aesthetics, and cost considerations.
