Basics of HVAC chiller

An HVAC chiller is a key component of heating, ventilation, and air conditioning (HVAC) systems used primarily for cooling large spaces or industrial processes. It works by removing heat from a liquid, typically water or a water-glycol mixture, through a vapor-compression or absorption refrigeration cycle.

Chillers are categorized into air-cooled and water-cooled types. Air-cooled chillers dissipate heat directly to the air using fans, while water-cooled chillers transfer heat to a separate water loop that then dissipates it through a cooling tower. Chillers consist of several essential components: a compressor, condenser, evaporator, expansion valve, and often a control unit.

These systems are crucial in maintaining comfortable indoor temperatures in buildings, as well as cooling equipment in industrial settings. Chillers are selected based on factors such as cooling capacity (measured in tons of refrigeration), energy efficiency, noise levels, and environmental impact. Regular maintenance, including cleaning condenser coils and checking refrigerant levels, is essential to ensure efficient operation and longevity of HVAC chillers.
