Just as horsepower and candlepower were intuitive units of measure for people living through the transition from horse to steam power [3] and from flame-based to electric lighting, so was the ton of refrigeration an intuitive unit of measure during a technological change, as the ice trade gradually included growing percentages of artificial ice ...
The first-generation ToyoAce was a one-ton truck of a semi-cab over design. It has a four-cylinder sidevalve inline-four " type S " engine of 1.0 L (995 cc) and 30 PS (22 kW). It was originally sold as the "Toyopet Light Truck", a not very inspired name which was changed for "ToyoAce" after a public contest in 1956. [ 2 ]
Serial numbers: EP 1 ⁄ 2 ton, ER 3 ⁄ 4 ton, & ES 1 ton. [5] Radios were first available in Chevrolet trucks as an "in dash" option on the "Advance-Design" body style. [6] 1948 - Manual transmission shifter now mounted on column instead of floor. Serial numbers codes: FP 1 ⁄ 2 ton, FR 3 ⁄ 4 ton, & FS 1 ton.
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.
Air changes per hour, abbreviated ACPH or ACH, or air change rate is the number of times that the total air volume in a room or space is completely removed and replaced in an hour. If the air in the space is either uniform or perfectly mixed, air changes per hour is a measure of how many times the air within a defined space is replaced each hour.
A dehumidifier is an air-conditioner-like device that controls the humidity of a room or building. It is often employed in basements that have a higher relative humidity because of their lower temperature (and propensity for damp floors and walls). In food retailing establishments, large open chiller cabinets are highly effective at ...
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.
At the bottom of the range, Dodge offered the three now common pick-up classes (1 ⁄ 2-ton, 3 ⁄ 4-ton and one-ton), as well as a 1 1 ⁄ 2-ton pickup. Dodge's half-ton pickups, on a 116 in (2.95 m) wheelbase with a 7 1 ⁄ 2 -foot box, now had the 70-horsepower 201-cubic-inch L-head straight-six.
