How to Manually Calculate Chiller Capacity for Your Process

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:

Apr 05, 2011 Q = Capacity in kW. M = Liquid mass flow rate kg/s. Cp = Liquid specific heat kJ/kg.K. DT = Liquid temperature difference C. Your mass flow rate is 0.166 kg/s. Q = 0.166 x 4.18 x (37-15) = 15.2 kW. You have to select a compressor which can give you 15.2 kW capacity at =3C evaporating and 50C condensing (if air cooled)

Apr 05, 2018 When operating below 50 F you must decrease the rated chiller cooling capacity by 2% for every one degree F you operate below 50 F. To correct for 45 F operation you would divide the chiller rated cooling load by 0.9. See calculation: 100% – (2% x 5 F below 50 F) = 90% or 0.9.
