Apr 04, 2019 Convert result into tons of chiller capacity. Divide Q (BTUs per hour) by 12,000 (the number of BTUs in one ton of cooling capacity). This yields the chiller capacity required to handle the process heat load in tons per hour: Example: 240,000/12,000= 20 tons/hr. Correct chiller tonnage for leaving water temp (LWT), if LWT is other than 50F:

There are two options for air cooling of an absorption chiller: 1. Use a conventional, water-cooled condenser and absorber, and substitute a dry coil for the cooling tower to reject heat to the ambient air; or 2. Replace the condenser and absorber with an air-cooled condenser and air-cooled absorber.
