[5] [6] [7] The area of refrigeration and deep freezers for supermarkets basically involves plug-in refrigeration and freezer systems [8] and constitutes approximately 60% of the total turnover, which was more than €200 million in 2007. [citation needed] The company is based in the region of Styria in the middle of Austria and has about 800 ...
The company claims to have innovated the refrigerator light, the upright freezer, and the "Air Sweep" mechanism for distributing conditioned air. In 1956, Hupp Corporation acquired Gibson. [ 2 ] In 1967 Hupp merged with White Consolidated Industries (WCI), which created the White-Westinghouse brand in 1975. [ 3 ]
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 ...
Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).

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 brand was originally created for a line of refrigerators. Other products sold under the Coldspot brand included freezers, dehumidifiers, and window air conditioning units.

Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]
