The good news is that new air conditioning systems made since no longer rely on Freon. This chemical is an HFC hydrofluorocarbon , but has been shown not to harm the ozone and, since , has become the standard for residential air conditioning. Many homeowners that would be affected by this new regulation have already switched to more environmentally friendly refrigerants. HVAC professionals have been phasing out freon gradually over the past eight years.
Older air conditioning systems that have been replaced according to schedule were likely switched out for RA units. Freon is really only an environmental hazard if it leaks or is disposed of improperly. Beginning in , Freon will no longer be produced or imported, but limited amounts will still be available. Older systems can be serviced or recharged with refrigerant using stocks of HCFC until the date.
After that, technicians will need to source recycled Freon to keep an old cooling system running. Though the EPA does not require homeowners to buy new air conditioning systems, retrofitting older systems is a valid option. Outlined below are a few of the main differences between refrigerants along with some additional guidance on why selecting the correct refrigerant for the desired application matters. System manufacturers have had great success with RA because of its energy efficient properties and ease of use in their systems.
In addition, components are widely available for designing efficient RA systems. Many air conditioning models are designed to be used with RA for a reliable and more efficient operation. Because RA can absorb and release more heat than R, an air conditioning compressor can run at a cooler temperature, reducing the risk of compressor burnout due to overheating. RA also functions at a higher pressure than R, so new compressors are built to withstand greater stresses, reducing the chance for cracking.
If someone were to put RA refrigerant into a system designed for R, the pressure could potentially be too high, causing the unit to potentially fail. Most air conditioners use oil to keep the compressor lubricated during operation. This means the RA system operates more efficiently, reducing wear and tear on the compressor.
The answer is probably, but only if it is approved by the compressor manufacturer. If you are unsure, always consult with the compressor manufacturer. In addition, temperature glide is a property of some HFC refrigerant blends or mixtures and is generally undesirable.
Because the composition alters during a phase change, there is a slight change in evaporating and condensing temperature at constant pressure. Contained within the coils of an air conditioner , these liquid agents cool and dehumidify indoor air.
For years, the most common refrigerant used in air-conditioning systems was R In response to growing environmental concerns, production of systems using R refrigerant is being phased out.
It is less reactive with the environment while having the same home cooling characteristics of R When you purchase a RA system, a new line set is included with your central air installation as well as a new evaporator coil.
Our experience with RA has been excellent.
