• Wall-mounted Split Air Conditioners: A mixture of homes and offices around Changi make use of split-type air conditioners usually mounted on the wall. These air conditioners can effectively cool down large spaces with just one unit, no longer needing to have separate units per room. Split air conditioners are relatively easy to maintain, compared to centralized cooling systems which are more suitable for large commercial spaces.
• Ceiling Cassette Air Conditioners: Ceiling Cassette Air Conditioners are suitable for medium spaces, as this type of cooling system takes up very little ground space. Ceiling cassette air conditioners may be placed on the wall or ceiling, and would require professional cleaning services for maintenance.
• Centralized Air Conditioners: The airport, hotels, malls, and other large commercial spaces around Changi benefit most from centralized air conditioners, where the cooling system is operated from a separate, single point. This type of air conditioner typically can withstand prolonged use, as well as cooling down large areas with vents strategically placed around the site. Centralized air conditioners, however, require consistent maintenance to keep the entire system running smoothly.
