Water Chiller Cooling Capacity Calculation

BTU/ hour = 500 x GPM x Temperature Difference (delta T) Repeat this for all the equipment you have, and add up the total BTUs. Now that you have the BTUs, compute the total tons of cooling you need from a chiller. For example, 1 Ton of cooling is 12,000 BTU/hour s.

Chiller Cooling Capacity - How to calculate - The ... Jul 22, 2017 Now lets look at how to calculate the cooling capacity of a chiller in imperial units. Imperial units: The flow rate of chilled water into the evaporator is measured as 12,649ft3/h and the chilled water inlet temperature is 53.6*F the outlet temperature is 42.8*F. Get Details

Dec 08, 2020 Chilled water-in 44 F. Chilled water-out 54 F. Estimated Δt - 10 F. Chilled water pressure drops - max. 20 ft of H2O. Flow rate - 2.4 gpm/ton. Water velocity – 2 fps ~ 3 fps. A typical chilled water system gives water at 44 F to an AHU at the inlet. Measure the water flow rate at the inlet of the AHU. We can measure the flow rate ...

Dec 29, 2018 This converts the volumetric flow rate to a mass flow rate, which is measured in pounds of water per hour. With this example: 3,900 x 500 = 1,950,000. This answer is the chiller's capacity measured in BTUs per hour. Divide your answer by 12,000: 1,950,000 / 12,000 = 162.5. This is the chiller's capacity in tons.

Estimate Chiller Cooling Tonnage. Water chillers are widely used to lower the temperature of water. This tool is useful in determining the cooling tonnage of the chiller. Flow Rate (LPH) Inlet Temp (C) Outlet Temp (C) Estimated Chiller Size (Tons) 0.

Jan 04, 2014 The energy flow into the chiller is: Qin = flowrate*heat_capacity*Tin The energy flow out of the chiller is: Qout = flowrate*heat_capacity*Tout The amount of heat you need to remove is: Q = Qin - Qout = flowrate*heat_capacity*(Tout - Tin) For water: heat_capacity = 4.18 kJ/kg-C 8 oz = 0.24 L = 0.24 kg The flowrate is 0.24 kg/42 s = 0.0057 kg/s

Jul 12, 2021 the chiller capacity calculation allows to know the thermal load that the machine needs, ... When the application of the chiller is for the cooling of machines, or for industrial processes, we must know: ... Chiller water pipe sizing …

Jul 19, 2009 Dear all, I have water-cooled chiller, I need to calculate its cooling output in KW. I have chilled water flow in GPM and supply return temperature in C. ... m=mass of water c=specific heat capacity of water 06-29-2009, 09:55 AM #3. Shophound. View Profile View Forum Posts Visit Homepage View Forum Threads ...

Jun 26, 2008 Cooling capacity of chiller and heat load calculation Cooling capacity of chiller and heat load calculation Jigneshpadia2002 (Bioengineer) (OP) 20 Jun 08 09:49. Can I please ask one question! ... I assumed to be water for the calculation purpose. Working volume is going to be 20 L = M = 20 Kg

Mar 12, 2020 Calculate Temperature Differential (ΔTF) ΔTF = Incoming Water Temperature (F) – Required Chill Water Temperature. Calculate BTU/hr. BTU/hr. Calculate tons of cooling capacity Tons = BTU/hr. Oversize the chiller by 20% Ideal Size in Tons = Tons x 1.2. You have the ideal size for your needs.

Mar 25, 2019 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 of chiller capacity per motor hp. For feed throat, add 0.5 ton of chiller capacity.

May 20, 2022 Figure 8 shows the effect of hot water flow rate on the chiller’s average cooling capacity and COP, while Figure 9 shows the effect of hot water flow rate on the hot water outlet temperature. The optimum hot water mass flow rate is 1.5 kg/s, which gives a maximum average cooling capacity of around 8 kW and a maximum COP of 0.26.

May 22, 2020 Calculation of Heat Rejection Capacity and Selection of Cooling Tower. T1 Inlet water temperature to chiller: 33℃ T2 Outlet water temperature after heat exchange: 38℃ M Water flow rate for chiller: 6000 liter/h. Heat rejection capacity calculation: Q = …

Method A. Watts = [ (DT) F x K] / S. Where. DT= the F difference between incoming and outgoing tap water temperature of your instrument. Measure carefully using the same thermometer for both locations. K = Specific heat multiplied by the density of the fluid being circulated. Use 2,326 for water when calculating load in F.

Nov 07, 2018 Calculate tons of cooling capacity equation: Tons = BTU/hr, 12,000. As a rule of thumb, you need to know at least three of these values in order to calculate the load: Flow rate ( fluid type), Inlet temperature, outlet temperature, and heat load or tonnage required. Going back to our example of a “10 ton” chiller requirement, we will ...

Nov 25, 2019 In order to find the PLR the available cooling capacity first needs to be calculated. The Qref must also be converted from tons to watts: Qavail = available c h iller capacity adjusted for current fluid temperatures W. Qavail = (Qref)(C h illerCapFTemp) Q ref = chiller capacity at reference conditions (W) Q ref =113 tons x 3516.85284 watts/ ton ...
