Topic: Domestic refrigerator


In the News (Tue 2 Dec 08)

  
  Refrigerator - refrigerator, refrigeration, temperature, ac, freezer, cold
The first refrigerators were of the "remote" type, essentially an upgrade of an existing ice box with the installation of a cooling unit in it, but the motor, compressor and condenser installed either beside it or in the basement.
Temperature settings for refrigerator and freezer compartments are given arbitrary numbers for example (1 through 9, warmest to coldest) by manufacturers, but generally 37 degrees F (3 degrees C) is ideal for the refrigerator compartment and 0 degrees F (-17 degrees C) for the freezer.
The refrigerator in your kitchen uses a cycle that is similar to the one described in the previous section.

 Labyrinth door seal for a refrigerator - Patent 5560694
The domestic refrigerator of claim 6 wherein the outer metallic door shell is folded at the flat mounting door surface to form an interface door surface extending generally orthogonal to the flat mounting door surface.
The domestic refrigerator of claim 8 wherein the first and second door liner surfaces respectively follow the contour of the flat mounting door surface and interface door surface of the outer metallic shell.
In the past, the refrigerator wall and the door liner were arranged to meet at an angle so that the arc traced by the door liner poses the least interference possible with the refrigerator wall.

Furthermore, refrigerator manufacturers are aware of the impact that new re fr igerator performance standards and the proposed consumer education and dealer incentive programs will have on demand for more energy efficient refrigerators.
Yet domestic compressors are relatively inefficient (currently, the avera ge COP of compressors produced in China ranges between 1 and 1.1, while a COP of 1.4 is achievable with the redesign of certain parts and the use of additional components).
Chinese refrigerator manufacturers are often un aware of the variety of measures that can be applied to increase energy efficiency, and of ways in which these measures can be implemented.

 A. D. Little Report: Domestic Refrigeration
The LCCP impact of a refrigerator consists of the indirect warming impact of the energy consumption and the direct warming impact of any refrigerant and blowing agent that is emitted from the refrigerator.
Depending on plant location and applicable local regulations, the small amounts of isobutane refrigerant that escapes during changing and of cyclopentane blowing agent that escapes during foaming must be captured by appropriate pollution control equipment, adding to the investment and operating costs of the manufacturing operation.
With respect to refrigerators, the use of HFC refrigerants in refrigerators results in negligible emissions that can be most cost-effectively offset by even small energy efficiency improvements.

 Refrigerator - Wikipedia, the free encyclopedia
A refrigerator (often called a "fridge" for short) is an appliance for the storage and preservation of perishable food; food kept in a refrigerator lasts longer than that left at room temperature as the cold inhibits bacterial growth.
A refrigerator maintains a cold temperature above the freezing point of water; commonly refrigerators are used in conjunction with freezers, which maintain temperatures below freezing, or a refrigerator may have an integrated freezer compartment.
Temperature settings for refrigerator and freezer compartments are often given arbitrary numbers (for example, 1 through 9, warmest to coldest) by manufacturers, but generally 2 to 8 °C (36 to 46 °F) is ideal for the refrigerator compartment and -18 °C (0 °F) for the freezer.

 A. D. Little Report
The refrigerants that have been used to replace CFC-12 in domestic refrigerators are HFC-134a and isobutane.
With current practices, refrigerant is charged into new refrigerators with negligible losses to the atmosphere and is contained throughout the life of the refrigerator.
End of life refrigerant recovery is mandated, with only a small portion of the charge lost to atmosphere during the recovery process.

Inside its walls, a refrigerant (ammonia, usually) is heated by a gas flame so as to vaporize; the ammonia gas then dissolves (or is absorbed into) a liquid (water, usually), and as it dissolves it simultaneously cools and condenses.
The refrigerating machinery was sold separately from the refrigerating compartment, which might well have been simply the icebox that a family had previously used; the machinery could be set up in the basement, say, and the icebox put in the kitchen.
The manufacturers of gas absorption refrigerators were not idle during these years, but they lacked the large sums of money, the armies of skilled personnel, the competitive pressure, and the aggressive assistance of utility companies that the compression manufacturers had been able to command.

 Domestic Cat Refrigerator Magnets
The cat (also called domestic cat, or house cat) is a small feline carnivorous mammal that has been domesticated for several millennia.
Cats (including domesticated cats) have a scent organ in the roof of their mouths called the vomeronasal, or Jacobson's organ.
Due to common cross-breeding in populated areas, many cats are simply identified as belonging to the homogeneous breeds of domestic longhair and domestic shorthair, depending on their type of fur.

A significant proportion of foodborne illnesses are due to cross-contamination in the domestic kitchen environment.
The goal of this study was to evaluate the prevalence and levels of pathogenic Enterobacteriacea and aerobic bacteria in domestic refrigerators.
The results indicate that kitchen refrigerators can be potential reservoirs for pathogenic bacteria; therefore, present a hazard for contaminating prepared foods and other parts of the domestic kitchen.

 New Energy-Efficient Chinese Refrigerator To Have Global Impact
Now, an internationally funded, award-winning project to improve the energy efficiency of Chinese refrigerators, developed by the Department of Energy’s Lawrence Berkeley National Laboratory, has received a green light from the government of China and international funders, and is set to start in early December.
The refrigerator project began in 1989 when the EPA signed an agreement with the government of China to assist in the elimination of CFCs from refrigerators.
The success of the design phase of the project, in which a prototype model of 40 percent greater efficiency was produced and tested, led to eventual multilateral support for the new phase.

 No Excuses - Domestic Refrigeration
Until recently, most domestic refrigerators were manufactured with the use of ozone depleting substances --CFC-11 in the insulation, and CFC-12 as the refrigerant.
During 1993/94 the natural refrigerants, hydrocarbons R290 (propane) and R600a (isobutane), or blends of R290/R600a, have emerged as the major contenders against the synthetic compound HFC-134a for market acceptance as refrigerant substitutes to CFC 12.
A mixture of propane (R290) and isobutane (R60Oa), or isobutane as a pure gas is used for the refrigerant, and cyclopentane is used as the blowing agent.
