FAQs About Air Chillers & Air Systems
What is a chiller HVAC?
- An air chiller is an industrial refrigeration system that cools fluids and works with a facility’s air handler system. A chiller system includes an evaporator, condenser, compressor and expansion valve. A chiller HVAC removes the heat and pumps condensed cool air inside.
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.
