Feb 05, 2021 We = V x (√Φ) x A. Where: W e = electrical power. V = voltage. Φ = phase. A = total amp draw. A few notes: For the voltage, taking the upper limit (for example, using 230V where the range provided is 200–230V) will give you a “worst case” approximation of the heat generated. The phase refers to whether the chiller has a single-phase ...

Jan 27, 2022 Calculations for chiller tonnage in the plastics industry are based on a coolant temperature of 50F (LWT), with sufficient capacity to handle a 10F-temperature rise in coolant from the processing load. So, if the LWT you need is above or below 50F, you’ll need to correct your chiller tonnage calculation accordingly.

Nov 07, 2018 How to Calculate Chiller Tonnage – Formula. The final step to convert your answer into tons of chiller capacity is to divide your result, Q (BTUs per hour), by 12,000 (the number of BTUs in one ton of cooling capacity). This will give you, in tons per hour, the chiller capacity that is needed to handle the process heat load.
Now that you have these two figures, calculate how many BTU’s (British Thermal Units) your equipment puts off. 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.
Qs = 303.8 x 1.72 x 5 = 2612.68 KJ = 625.04 KCal. And now i need to calculate the major thing the Latent heat, QL. QL = 303.8 x 351 = 106633.8 KJ = 25510.48 KCal. So the Total energy is Q = Qs + QL = 625.04 +25510.48 = 26135.52 KCal. So Now the required TR is 26135.52 / 3024 = 8.64 TR. So for the above operation of cooling a 350 L toluene ...
Sep 23, 2019 W = average cooling power (W) V = total system liquid volume (L) T = temperature difference (C) K = liquid heat capacity (J/L/C) This formula can be helpful, but it’s a good idea to add on at least 20 percent more wattage to be on the safe side. After all, it’s highly unlikely that any system is going to be 100 percent efficient.
The flow rate. General sizing formula: Calculate Temperature Differential (ΔTF) ΔTF = Incoming Water Temperature (F) – Required Chill Water Temperature. Calculate BTU/hr. BTU/hr. = Gallons per hr x 8.33 x ΔTF. Calculate tons of cooling capacity Tons = BTU/hr. 12,000. Oversize the chiller by 20% Ideal Size in Tons = Tons x 1.2.
