Chiller Sizing Formula Cooling Capacity Of Chillers How To Using the energy equation of q = ṁ x cp x Δt we can calculate the cooling capacity. q = (16,649ft3 h x 62.414lb ft3) x 1.0007643btu lb.f x (53.6f – 42.8f) giving us a cooling capacity of 8,533,364btu h. see full calculations below. chiller cooling capacity calculation imperial units how to calculate cooling capacity of a chiller. 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.
Chiller Cooling Capacity How To Calculate The Engineering Mindset Now, if we put it all together once again, the chiller capacity formula becomes as follow: q = ρvcθ. q = (kg m 3) (m 3 s) (kj kg. °c) (°c) q = kj s = kw. once you’ve calculated the q in kw, you also can multiply it by 3412 to convert it into btu hr and then divide it by 12000 to convert it into tr. Calculate tons of cooling capacity. tons = btu hr. ÷ 12,000; oversize the chiller by 20%. ideal size in tons = tons x 1.2; if you follow these steps, you should have the ideal chiller size for your needs. here’s an example of the formula in action: scenario: what size chiller is required to cool 40gpm from 70°f to 58°f??t°f = 70°f – 58. For each material type, divide the total pounds processed per hour by the number of pounds per hour that can be processed with one ton of cooling, per the chart. for example, to injection mold pet at a rate of 300 pounds per hour, the material calculation is 300 45 = 6.67 tons of chilling capacity per hour. for hydraulic motors, add 0.1 ton. Q = 711 tr refrigeration tons. to convert it into btu h multiply above value with 3412.142. q = 2500 kw x 3412.145. q = 853357 btu h. so that is how you calculate your cooling capacity of the chiller and you can apply this any time during its operation, whether it's a part load or a full load, it will be calculated like this.

The definitive guide to chiller sizing: everything you need to know about calculating the right size of a chiller the basics of chiller sizing. keywords: chiller sizing guide, chiller size calculator, how much cooling is needed) the first step in sizing a chiller is to determine the total cooling load. this is the sum of all the cooling loads. The flow rate. general sizing formula: calculate temperature differential (Δt°f) Δt°f = incoming water temperature (°f) – required chill water temperature. calculate btu hr. btu hr. = gallons per hr x 8.33 x Δt°f. calculate tons of cooling capacity tons = btu hr. ÷ 12,000. oversize the chiller by 20% ideal size in tons = tons x 1.2.
