What is a ton of refrigeration?
A ton of refrigeration is 12,000 BTU per hour, about 3.517 kW of cooling. It comes from the heat needed to melt one short ton of ice in a day. Central air systems for homes are sold in sizes of 1.5 to 5 tons.
What is a kilowatt?
The kilowatt equals 1,000 watts. It rates electric heaters, car engines outside the US, solar installations and home electrical service. Running 1 kW for one hour uses 1 kilowatt-hour of energy.
