Under these Rules, most HFC uses in polyurethane and other foams and in new retail food refrigerated cases will be phased out between January 1, and January 1 Use of HFCs in mobile air conditioning will end with Model Year , while prohibitions on HFC use in new fire suppression systems, cold storage, residential refrigeration, and building chillers go into place on January 1 of , , and , respectively.
In addition to the various production bans, servicers and disposers of appliances and motor vehicle air conditioners are required to obtain technician certification, proper refrigerant recovery or recycling equipment, and keep records.
Skip to main content. Air How's the air? Ozone depletion or ODS is the decay of the protecting ozone layer that filters out harmfull UV light. An ozone depleting substance can remain in the stratosphere for long periods, causing holes in the layer and allowing harmful UV rays to reach the earths surface.
The green house effect as the name suggests, relates to the warming of the earths surface temperatures. This upsets the balance in the earths Eco systems. R soon followed suit and in R was no longer allowed to be used in any new machines.
In production and imports of R was cut drastically, and in R will be completely phased out in the United States. In an effort to solve the issue the Montreal Protocol was formed. Hydrochlorofluorocarbons , or HCFCs, are chemicals that are mainly used as refrigerants. Unfortunately, releases of HCFCs deplete the Earth's protective ozone layer and contribute to climate change.
R is an HCFC refrigerant that is often used in air-conditioning equipment. HCFC Refrigerants. HCFCs contain chlorine, fluorine, and carbon just like CFC , but also contain a hydrogen atom which decreases their stability and gives them a shorter lifetime in the atmosphere. They mostly break down before they reach the ozone. These are service refrigerants used in existing equipment.
Which refrigerant is banned? From , it will be illegal to use Hydrochlorofluorocarbons HCFCs , including the ozone-depleting refrigerant gas R22, in refrigeration, heat pump and air conditioning AC systems.
R22 is commonly used in AC systems pre-dating and so its ban will have a major effect on air-conditioning costs. What does HCFC mean?
Hydrochlorofluorocarbons HCFCs are a large group of compounds, whose structure is very close to that of Chlorofluorocarbons CFCs , but including one or more hydrogen atoms.
