FAQs About Air Chillers & Air Systems

What is the difference between an HVAC and a chiller?

• An air conditioner dehumidifies and removes heat from an area, and the cooling is done with a simple refrigerator system. A chiller removes heat from a liquid through a vapor-compressed or absorption refrigeration cycle.

How many types of air chillers are there?

• There are two types of air chillers: air-cooled and water-cooled. Air-cooled chillers are usually outside and are made of condenser coils cooled by fan-driven air. Water-cooled chillers are usually inside, and heat is carried by recirculating water to a heat sink.
