How to Manually Calculate Chiller Capacity for Your Process

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:

Cooling Tower Tons. A cooling tower ton is defined as: 1 cooling tower ton = 1 TONS evap = 1 TONS cond x 1.25 = 15000 Btu/h = 3782 k Calories/h = 15826 kJ/h = 4.396 kW. The equivalent ton on the cooling tower side actually rejects about 15000 Btu/h due to the heat-equivalent of the energy needed to drive the chiller's compressor. This equivalent ton is defined as the heat …
