Cooling capacity conversion: kcal/h to Tons TR
Chinese industrial chillers commonly use kcal/h to express cooling capacity. To match the unit’s usual use, we can suppose.
1 TR=3024 kcal/hr
For example, a chiller rated at 100000 kcal/h is equivalent to 33.07 TR. For a chiller rated at kW, use 1 TR = 3.517 kW. Using the above expressions can help Chinese expressions align with the rest of the world.
From Cooling Capacity to Compressor Power
Compressor power reflects the energy demands of the chiller. Using the Coefficient of Performance (COP), calculate compressor input power with the formula:
Compressor Power (kW)=Cooling Capacity (kW)/COP
For example, a chiller with a cooling capacity of 116.3 kW and a COP of 4.0 requires 29.08 kW, or about 38.98 HP using 1 HP=0.746 kW.
Explaining Compressor Power on Chinese Nameplates
Chinese chillers may also list the total input power on the nameplate, covering the compressor, pumps, and fans. You can confirm the relationship to the cooling demand using COP:
COP=Cooling Capacity (kW)/Input Power (kW)
Typical COP values:
- Air-cooled chillers: COP ≈ 3.0–4.0
- Water-cooled chillers: COP ≈ 4.0–6.0
For compressor motor power:
Compressor Power (HP)=Input Power (kW)/0.746
Expanding Chinese Chiller Types
Our factory produces a wide range of chillers, including industrial air-cooled, water-cooled, and screw chillers, designed for high efficiency, durability, and tailored to diverse industrial needs.
Model confidential simplification
The conversion tables can help list Chinese chillers with people’s needs worldwide. For example, a 200000 kcal/h chiller or 66 chilling machine with about 58.15 input power and corresponding compressor power of about 77.95HP.
You can achieve model consistency very well if you are good at these.
Chiller model conversion table
The following shows a chiller model conversion table for Chinese chiller models with a table up to 1000 TR, including expressions of the chiller’s cooling capacity, compressor power, and corresponding international chiller models.
