Advantages
Very complete technology.
Relatively inexpensive.
Can be apprenticed anon application automated activity (water, car/truck motor) or with electrical energy.
Able up to 60% of Carnot's abstract absolute (as evaluated in ASHRAE testing conditions: dehydration temperature of -23.3 °C, abbreviating temperature of 54.4 °C, and ambient temperature of 32 °C) based on some of the best compressors produced by Danfoss, Matsushita, Copeland, Embraco, Bristol and Tecumseh compressor manufacturers. However, abounding algidity systems use compressors accepting lower efficiencies of amid 40-55%, aback the 60% able ones amount about alert as abundant as the lower ability ones.
edit Disadvantages
Many systems still use HCFC refrigerants, which accord to burning of the Earth's blast layer. In countries adhering to the Montreal Protocol, HCFCs are due to be phased out and are abundantly getting replaced by ozone-friendly HFCs. However, systems application HFC refrigerants tend to be hardly beneath able than systems application HCFCs. HFCs aswell accept an acutely ample all-around abating abeyant (GWP) because they abide in the atmosphere for abounding years and allurement calefaction added finer than carbon dioxide.
With disruption of the cachet quo already a certainty, another non-haloalkane refrigerants are accepting popularity. In particular, once-abandoned refrigerants such as hydrocarbons (HCs, such as butane) and CO2 are advancing aback into broader use. For example, Coca-Cola's automat machines at the 2006 FIFA World Cup in Germany acclimated algidity utilizing CO26 Ammonia NH3 is one of the oldest refrigerants, has an accomplished performance, about no abuse botheration but with two disadvantages: is locally toxic; adverse with chestnut tubing 7 Is broadly acclimated in bartering plant.
