How many kW is a nW?

Nanowatt to Kilowatt Conversion Table

How do you convert nm to kW?

Torque (Nm) to kW calculation: kW = 0.105 x Nm x rpm / 1000. Example: A three-phase induction motor can provide 144Nm at 1480 rpm.

What does kW ton mean?

KW/ton is a measure of efficiency that is equal to the Peak Power Draw (kw) divided by the Peak cooling consumption (tons). A lower KW/ton means a unit is more efficient.

How do you calculate kW and TR?

In English terminology, 1 TR is 3024 KCal. Learn How the value of 3024 KCal or 3.517 KW derived…..!! One short ton = 2000 lb, Heat extracted = 2000 x 144/24 hr = 288000 Btu/24 hr = 12000 Btu/hr = 200 Btu/min, 1 ton refrigeration = 200 Btu/min = 3.517 kJ/s = 3.517 kW = 4.713 HP .

How many watts is 3 tons?

A three ton central air conditioner uses 3500 watt per hour and a 12,000 watt window unit uses 1200 watt per hour as a general reference point.

Why is AC rated in tons not in kW?

Refrigeration and air-conditioned (AC) systems are always rated in Tons. Air conditioners are rated in Tons capacity instead of kW or kVA rating because Air conditioners are designed on the basis of quantity of heat removal from room, hall or specific area.

What is the difference between kW and Nm?

Kilowatt is a function of torque and revolutions per minute and is calculated as following: Power (kW) = torque (Nm) x speed (revolutions per minute, or RPM) / 9.5488. So how does my car’s engine make power? The more torque an engine produces, the greater its ability to do work.

How to convert kilowatt to ton in refrigeration?

How to Convert Kilowatt to Ton (refrigeration) 1 kW = 0.2843451361 ton (refrigeration) 1 ton (refrigeration) = 3.5168528421 kW Example: convert 15 kW to ton (refrigeration):

How much does a sheet chiller cost per ton?

How to calculate the cooling load of a water chiller?

Some commercial and industrial refrigeration systems are rated in Tons of Refrigeration (TR, tons). A water-chiller refrigeration ton is defined as: 1 Refrigeration Ton (RT) = 1 TONS cond = 12000 Btu /h = 200 Btu /min = 3025.9 k Calories /h = 12661 kJ/h = 3.517 kW

How to calculate the cooling load of a ton?

1 Refrigeration Ton (RT) = 1 TONScond = 12000 Btu/h = 200 Btu/min = 3025.9 k Calories/h = 12661 kJ/h = 3.517 kW. 1 kW = 0.2843 Refrigeration Ton (RT) A ton is the amount of heat removed by an air conditioning system that would melt 1 ton (2000 lbs.) of ice in 24 hours.
