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 rejection in cooling ..

Correct chiller tonnage for leaving water temp (LWT), if LWT is other than 50°F: Calculations for chiller tonnage in the plastics industry are based on a coolant temperature of 50°F (LWT), with sufficient capacity to handle a 10°F-temperature rise in coolant from the process load.. So, if the LWT you need is above or below 50°F, you’ll ..
12,566*62..4 lbm/cu ft = 784,141 lbm.. Assuming 10°F ΔT, that's 7,841,410 Btu in storage.. 7,841,410 Btu / 12,000 Btu/h/ton = 653 ton-hours.. Calculation above does not take any losses into account, nor the fact that you can't get back of the energy you spent in cooling it, nor any allowance for decreasing effectiveness of heat exchangers as ..
The basic tonnage is based on chilled water, if you wish to chill a fluid to 15F then glycol or another low freezing point fluid must be used, your 60tons machine will NOT make 60 tons as rated cause the specific heat of such fluid will be lower than water, you can increase the flow through the chiller barrel and get closer to the rated tonnage but it all comes with a price and a penalty..
Im trying to calculate BTU for chiller that has to do following thing: Cool 200 tons of sea water from 22C to 2C in 24 hours.. There are 2 options: A) 22C inlet and 2C outlet temp with water flow 200 ton/day B) Big water tank and recirculating water.. Would you be so kind to help me with a rough estimate.. Thank you, Best regards
Each chiller is designed to deliver chilled water at a certain flow rate with a certain temperature difference.. Tonnage is calculated as follows: GPM x ∆ T︒ ÷ 24.. For example, if the chiller has a flow rate of 550 GPM and the Delta T is 4..8〫F, then the tonnage would be 110 Tons..
Step 2.. Calculate the chiller capacity in tons of refrigeration.. The formula for total heat removed in a chiller installation is h = 500 X q X dt where h = total heat removed in Btu/hr, q is the chilled water flow rate in gpm, and dt is the chilled water's total temperature differential.. Substituting, h = 500 X 40 gpm X 24 deg-F = 480,000 Btu ..
