The pump forces the cooling agent via the circuit of tubing and fins in the coils.
The hot refrigerant gas is pumped outdoors right into the condenser where it changes back to a liquid, quiting its heat to the outdoors air streaming over the condenser's steel tubes as well as fins. Throughout the second fifty percent of the 20th century, virtually all a/c utilized chlorofluorocarbons (CFCs) as their refrigerant, however because these chemicals are harming to Planet's ozone layer, CFC manufacturing dropped in the USA in 1995.

Manufacturing and importing of today's major cooling agent for house air conditioners, HCFC-22 (additionally called R-22), began to be terminated in 2010 and will certainly quit completely by 2020. Nevertheless, HCFC-22 is anticipated to be readily available for years as it is recouped from old systems that are secured of service.
