中文百科

冷冻吨 Ton of refrigeration

(重定向自Refrigeration ton)

冷冻吨简称RT,是一些国家用来描述冷冻及空调能力的功率单位。

冷冻吨定义为在摄氏零度下将一短吨(2,000磅)的冰熔化24小时的产生的熔化热。一冷冻吨等于一天消耗一短吨的冰,用其熔化热来冷却的功率。

一冷冻吨约等于12,000 BTU/h=3024千卡/h=3.517kW,美国的空调或冷冻设备常用吨标示其冷冻能力,此处的吨即为冷冻吨。若是较小型的空调或冷冻设备,也可能会改用BTU/h来标示。

A ton of refrigeration (commonly abbreviated as TR) is a unit of power used in some countries (especially in North America) to describe the heat-extraction capacity of refrigeration and air conditioning equipment. It is defined as the heat of fusion absorbed by melting 1 short ton (2,000 lb; 0.893 long tons; 0.907 t) of pure ice at 0 °C (32 °F) in 24 hours. It is equivalent to the consumption of one ton of ice per day and originated during the transition from stored natural ice to mechanical refrigeration.
