Chiller - Use in Air Conditioning

Use in Air Conditioning

In air conditioning systems, chilled water is typically distributed to heat exchangers, or coils, in air handling units or other type of terminal devices which cool the air in its respective space(s), and then the water is re-circulated back to the chiller to be cooled again. These cooling coils transfer sensible heat and latent heat from the air to the chilled water, thus cooling and usually dehumidifying the air stream. A typical chiller for air conditioning applications is rated between 15 and 1500 tons (180,000 to 18,000,000 BTU/h or 53 to 5,300 kW) in cooling capacity, and at least one manufacturer can produce chillers up to 6,000 tons of cooling. Chilled water temperatures can range from 35 to 45 degrees Fahrenheit (1.5 to 7 degrees Celsius), depending upon application requirements.
