2. Ton of refrigeration - Wikipedia

   en.wikipedia.org/wiki/Ton_of_refrigeration

   It was originally defined as the rate of heat transfer that results in the freezing or melting of 1 short ton (2,000 lb; 907 kg) of pure ice at 0 °C (32 °F) in 24 hours. [1] [2] The modern definition is exactly 12,000 Btu IT /h (3.516853 kW). Air-conditioning and refrigeration equipment capacity in the U.S. is often specified in "tons" (of ...

3. Refrigeration - Wikipedia

   en.wikipedia.org/wiki/Refrigeration

   The measured capacity of refrigeration is often dimensioned in the unit of kW or BTU/h. Domestic and commercial refrigerators may be rated in kJ/s, or Btu/h of cooling. For commercial and industrial refrigeration systems, the kilowatt (kW) is the basic unit of refrigeration, except in North America, where both ton of refrigeration and BTU/h are ...

4. Cubic ton - Wikipedia

   en.wikipedia.org/wiki/Cubic_ton

   For the cubic ton, the situation is more complex—there are different cubic tons for different materials. The 1964 Reader's Digest Great Encyclopaedic Dictionary gave the following ton-derived volumes: Timber, 40 cubic feet or 480.0 bd ft or 1.133 m 3; Stone, 16 cubic feet (0.453 m 3) Salt, 42 US bushels (1.480 m 3) Lime, 40 US bushels (1.410 m 3)

5. Cascade refrigeration - Wikipedia

   en.wikipedia.org/wiki/Cascade_refrigeration

   [1] In a cascade refrigeration system, two or more vapor-compression cycles with different refrigerants are used. The evaporation-condensation temperatures of each cycle are sequentially lower with some overlap to cover the total temperature drop desired, with refrigerants selected to work efficiently in the temperature range they cover.

6. Ton - Wikipedia

   en.wikipedia.org/wiki/Ton

   For practical purposes the displacement ton (DT) is a unit of volume, 35 cubic feet (0.9911 m 3), the approximate volume occupied by one ton of seawater (the actual volume varies with salinity and temperature). [16] It is slightly less than the 224 imperial gallons (1.018 m 3) of the water ton (based on distilled water).

7. Cubic foot - Wikipedia

   en.wikipedia.org/wiki/Cubic_foot

   The IEEE symbol for the cubic foot per second is ft 3 /s. [1] The following other abbreviations are also sometimes used: ft 3 /sec; cu ft/s; cfs or CFS; cusec; second-feet; The flow or discharge of rivers, i.e., the volume of water passing a location per unit of time, is commonly expressed in units of cubic feet per second or cubic metres per second.
