One ton of refrigeration is the refrigeration produced by melting one ton of ice at 32°F in 24 hours. It is the rate of removing heat equivalent to 12,000 British thermal units per hour (Btu/hr) or 200 Btu/min. For more details on refrigeration principles, see References Kern, 1950, and Smith, VanNess, and Abbott, 2005. Webthe first figure, you can see that the heat rejection at the evaporator and condenser change from air to water as you move from split system to water cooled chilled water system. This change in heat rejection from air to water greatly improves the efficiency because the heat transfer is much better with water due to its increased heat capacity. pension asl
