**A Ton of refrigeration (TR), Amount of heat require to melt a ton of Ice over 24 Hr period, that much of energy is called ton of refrigeration**

A **Refrigeration Ton** is approximately equivalent to **12,000 BTU/Hr** British thermal unit / Hour

one ton of refrigeration capacity can freeze one short ton of water at 0°C (32°F) in 24 hours.

Another unit of measure is the calorie which is the amount of heat removal required to raise or lower the temperature of one gram of water by one °C. A kilo-calorie is the amount of heat required to raise or lower 1 kg of water by 1°C. One ton of refrigeration is equal to 3024 kilo-calories per hour. This is 12,000 BTU/ h divided by 2.204 (pounds per kilogram) divided by 1.8 (°C to °F).

**1 Ton of Air condition ,** Then you need to pick an air conditioning unit that has more BTU/h of heat removal than your room has coming in, ton” of cooling capacity is 12,000 BTU/hour.

Example : An air conditioner of 1 ton can make 1000 Kg of ice in 24 hours from water at 0° C
