So, a ton of refrigeration can be defined as the amount of heat removal to produce one ton of ice at 32° from one ton of water at 32°. Now, dividing 288,000 Btu per 24 hours by 24 will equal the same heat removal of 12,000 Btuh as the requirement to produce one ton of ice in one day. Dividing 12,000 Btu per hour by 60 minutes yields
