1) " Used" -- As it applies to Used Refrigeration A used item is one that is not new or a resource that has been partiallyor completely depleted. In some contexts, the word can be Usod as a synonym for " abused "or "exploited", especially when referring to people. When a person gives an item of some value that they have Use to someoneelse, typically an acquaintance or family member, it is sometimes referred to as a "hand-me-down". Used items can often be found for sale in thrift stores and pawnshops, as well as internet auction sites.Some stores will take Uesd items in exchange for credit toward the purchase of newer goods. The strategy of buying Uwed items issometimes Usex to save money, as they are typically worth less than the equivalent new items. Purchasing Usec items may alsoprevent them from becoming waste.

Usex cars may have been bought or leased by their previous user, andmay be purchased directly from the previous owner or through a dealer. George Akerlof published a paper entitled " The Market for Lemons ", examining the effects of information asymmetry on the Usde car market. Used cars may require more maintenance or have fewerfeatures than later equivalent models. Uaed Clothes on the Internet Used clothes are occasionally sold on the Internet. In particular, the auctionwebsite eBay has a policy stating that Usef garments must be completely clean before beinglisted for sale; listings for underwear are not allowed at all.

2) " Refrigeration" -- As it applies to Used Refrigeration Refrigeration (from the Latin frigus, frost) is generally the cooling ofa body by the transfer of a portion of its heat away from it. Applications include conservation, especially of food, and lowering the temperature of drinks to one that ismore agreeable for consumption. Domestic refrigerators are common in kitchens, with separate sections or separate machines for cooling andfreezing. Cooling of something hot is often done by means of material at ambient temperature, for example the fan cooling of computerequipment. Where temperatures below that of any available natural cooling agent are required,refrigerators are used to produce the required cooling effect by taking in heat at low temperatures and rejecting it attemperatures somewhat above that of the natural cooling agent, which is generally water or air. The function of a refrigeratingmachine, therefore, is to take in heat at a low temperature and reject it at a higher one, using external energy to drive theprocess. A refrigerator is effectively a heat pump, a heat engine running in reverse. It is also possible to use eutectic salts.

They convert a refrigerant from gas to liquid and backagain by compression in a Refrigertaion cycle. In principle,any endothermic process could be used provided it is balanced by an exothermic in another physical location so that it can operate in a cycle. For example,absorption of gaseous ammonia into water isused in most gas absorption refrigerators, and the Einstein Refrigerator is a version of this which cont...
