About Kilocalorie per Hour (thermochemical)
Kilocalories per hour is a thermal power rate using the thermochemical kilocalorie (4,184 J per kcal) spread over one hour.
About Ton of Refrigeration (TR)
One ton of refrigeration (TR) equals 12,000 BTU/h (IT), approximately 3,516.85 W. It is widely used in HVAC and refrigeration sizing.
How to convert kilocalories per hour (thermochemical) to tons of refrigeration (tr)
1 kilocalorie per hour (thermochemical) is equal to 0.00033047223595 ton of refrigeration (tr) when both are expressed in watt-equivalents:
1 kcal_h = (1.1622222222222223 W ÷ 3,516.8528420666667 W) tr = 0.00033047223595 tr
Each kilocalorie per hour (thermochemical) is defined as 1.1622222222222223 W and each ton of refrigeration (tr) as 3,516.8528420666667 W in this tool, so one kcal_h equals 1.1622222222222223 ÷ 3,516.8528420666667 tr = 0.00033047223595 tr.
Let d(kcal_h) be the numeric value in Kilocalorie per Hour (thermochemical) (kcal_h), and d(tr) the value in Ton of Refrigeration (TR) (tr). Then:
d(tr) = d(kcal_h) × (1.1622222222222223 / 3,516.8528420666667)
Equivalently, divide by how many kcal_h fit into one tr (watts per tr divided by watts per kcal_h):
d(tr) = d(kcal_h) ÷ 3025.9728086615678
Or: ton of refrigeration (tr) = kilocalorie per hour (thermochemical) ÷ 3025.9728086615678
Examples
Example #1: Convert 1 kcal_h to ton of refrigeration (tr)
1 kcal_h = 1 kcal_h × (1.1622222222222223/3,516.8528420666667) tr = 0.0003304722 tr
1 kcal_h = 1 kcal_h ÷ 3025.9728086615678 = 0.0003304722 tr
Intermediate watts: 1.1622222222 W
Example #2: Convert 10 kcal_h to ton of refrigeration (tr)
10 kcal_h = 10 kcal_h × (1.1622222222222223/3,516.8528420666667) tr = 0.0033047224 tr
10 kcal_h = 10 kcal_h ÷ 3025.9728086615678 = 0.0033047224 tr
Intermediate watts: 11.6222222222 W
Summary
To convert Kilocalorie per Hour (thermochemical) to Ton of Refrigeration (TR), multiply the value in kcal_h by the ratio of watts per kcal_h divided by watts per tr. Equivalently: value_tr = value_kcal_h × (1.1622222222222223 / 3516.8528420666667). Numerically, 1 kcal_h equals 0.0003304722359492433 tr.
