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).
