Air-cooled chillers use ambient air to cool the refrigerant and expel heat. They are typically used in smaller installations or where water resources are limited. These chillers are known for their ease of installation and lower initial cost.
Water-cooled chillers use water from a cooling tower to cool the refrigerant. They are more efficient than air-cooled chillers and are suitable for larger installations. These chillers require a constant water source and are often used in commercial and industrial applications.
Absorption chillers use a heat source, such as steam or hot water, to drive the refrigeration cycle. They are typically used where waste heat is available or where electricity is expensive. Absorption chillers are more environmentally friendly and can operate on renewable energy sources.
