Chiller Refrigeration Tons
The process of cooling is called refrigeration. For commercial and industrial refrigeration systems most of the world uses the kilowatt (kW) as the basic unit of refrigeration. Some commercial and industrial refrigeration systems are rated in Tons of Refrigeration (TR, tons). A water-chiller refrigerationtonis defined as: 1 Refrigeration Ton (RT) =...
How do I convert kW to tons of cooling?
Therefore, 1 Ton of cooling = (12,000 BTU/h)*(1 kWh)/(3412.142 BTU) = 3.5168 kW. So if you want to figure out how many Tons of cooling is required for x number of kW of power consumed [or heat generated], simply divide the total kW by 3.5168.
How will convert kVA and kW?
kVA to kW calculation formula The real power P in kilowatts (kW) is equal to the apparent power S in kilovolt-amps (kVA), times the power factor PF: P(kW) = S(kVA) × PF So kilowatts are equal to kilovolt-amps times the power factor.
How many kW are in a ton of cooling?
We use a conversion factor of 3.5168 kW/Ton of cooling. The theory is below. Fact: 1 kWh = 3412.142 BTU Fact: 1 Ton of cooling capacity = 12,000 BTU/h Therefore, 1 Ton of cooling = (12,000 BTU/h)*(1 kWh)/(3412.142 BTU) = 3.5168 kW.
How many watts in a ton of refrigeration?
So, 1 ton of refrigeration = 1 × 3516.85284 = 3516.85284 watts. Quote of the day... "If you can't explain it simply, you don't understand it well enough." Show me Another Quote! To calculate a ton of refrigeration value to the corresponding value in watt, just multiply the quantity in ton of refrigeration by 3516.85284 (the conversion factor).
