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 ...
The COP of absorption chillers can be improved by adding a second or third stage. Double and triple effect chillers are significantly more efficient than single effect chillers, and can surpass a COP of 1. They require higher pressure and higher temperature steam, but this is still a relatively small 10 pounds of steam per hour per ton of cooling.
The G-506 trucks, 1 + 1 ⁄ 2-ton, 4x4, produced as the Chevrolet G7100 (and originally G4100) models, were a series of (light) medium four wheel drive trucks used by the United States Army and its allies during and after World War II. This series came in standard cargo, as well as many specialist type bodies.
For the Zion National Park visitors' center, which uses two passive cooling towers, the cooling energy intensity was 14.5 MJ/m 2 (1.28 kBtu/ft 2;), which was 77% less than a typical building in the western United States that uses 62.5 MJ/m 2 (5.5 kBtu/ft 2). [16]
A representative pressure–volume diagram for a refrigeration cycle. Vapour-compression refrigeration or vapor-compression refrigeration system (VCRS), [1] in which the refrigerant undergoes phase changes, is one of the many refrigeration cycles and is the most widely used method for air conditioning of buildings and automobiles.
The 1 + 1 ⁄ 4-ton, 4×4, Kaiser Jeep M715, sometimes called the "Five quarter (ton)", for its 1 + 1 ⁄ 4 (or 5 ⁄ 4) ton payload rating, is an American light military truck, based on the civilian Jeep Gladiator (SJ). Design and development for the M715 began in 1965, intended to replace the Dodge M37.
The idle car problem was the problem of refrigeration cars sitting pointlessly in between seasonal harvests. This meant that very expensive cars sat in rail yards for a good portion of the year while making no revenue for the car's owner. The car pool was a system where cars were distributed to areas as crops matured ensuring maximum use of the ...
