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.
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.
How to convert tons of refrigeration (tr) to kilocalories per hour (thermochemical)
1 ton of refrigeration (tr) is equal to 3025.9728086615678 kilocalorie per hour (thermochemical) when both are expressed in watt-equivalents:
1 tr = (3,516.8528420666667 W ÷ 1.1622222222222223 W) kcal_h = 3025.9728086615678 kcal_h
Each ton of refrigeration (tr) is defined as 3,516.8528420666667 W and each kilocalorie per hour (thermochemical) as 1.1622222222222223 W in this tool, so one tr equals 3,516.8528420666667 ÷ 1.1622222222222223 kcal_h = 3025.9728086615678 kcal_h.
Let d(tr) be the numeric value in Ton of Refrigeration (TR) (tr), and d(kcal_h) the value in Kilocalorie per Hour (thermochemical) (kcal_h). Then:
d(kcal_h) = d(tr) × (3,516.8528420666667 / 1.1622222222222223)
Equivalently, divide by how many tr fit into one kcal_h (watts per kcal_h divided by watts per tr):
d(kcal_h) = d(tr) ÷ 0.00033047223595
Or: kilocalorie per hour (thermochemical) = ton of refrigeration (tr) ÷ 0.00033047223595
Examples
Example #1: Convert 1 tr to kilocalorie per hour (thermochemical)
1 tr = 1 tr × (3,516.8528420666667/1.1622222222222223) kcal_h = 3025.97280866 kcal_h
1 tr = 1 tr ÷ 0.00033047223595 = 3025.97280866 kcal_h
Intermediate watts: 3,516.85284207 W
Example #2: Convert 10 tr to kilocalorie per hour (thermochemical)
10 tr = 10 tr × (3,516.8528420666667/1.1622222222222223) kcal_h = 30259.7280866 kcal_h
10 tr = 10 tr ÷ 0.00033047223595 = 30259.7280866 kcal_h
Intermediate watts: 35,168.5284207 W
Summary
To convert Ton of Refrigeration (TR) to Kilocalorie per Hour (thermochemical), multiply the value in tr by the ratio of watts per tr divided by watts per kcal_h. Equivalently: value_kcal_h = value_tr × (3516.8528420666667 / 1.1622222222222223). Numerically, 1 tr equals 3025.972808661568 kcal_h.
Relationship context
You are converting between apparent power at unity PF (VA) (Tons of Refrigeration (TR)) and thermal engineering rates (BTU/h, kcal/h) (Kilocalories per Hour (thermochemical)). All linear values are mapped through watts first. The numeric factor is 3.025973e+3.
