R-410A The New Refrigerant for Air Conditioning

R-410A possesses excellent cooling capacity and operates at 50% higher pressure. R-410A is a mixture (blend) of refrigerants that create properties nearly identical to R-22, but are free of ozone depleting chlorine molecules. R-410A was developed in response to an agreement between numerous countries (known as the Montreal Protocol). That stated that those countries would move toward discontinuing the use of hydrochloro-fluorocarbon (HCFC)-based refrigerants. R-410A, chemically known as an HFC (hydrofluorocarbon), contains no chlorine and will not damage the ozone layer.

R-410A is an azeotrope mixture of R-32 and R-125. R-410A cannot be used to retrofit existing R-22 a/c equipment due to significantly higher operating pressures and much higher cooling capacity as outlined in the chart below. R-410A when operating at normal operating pressures and temperatures has higher pressures. R-410A cannot be used as a "drop-in" replacement for R-22; the higher operating pressures will damage R-22 compressors and components. Therefore the old R-22 refrigerant systems needed to be buffed up some to handle the higher pressures. Because of this R-410A and R-22 equipment cannot be cross matched.

R-410A has unique performance specifications and characteristics for oil, moisture indication, thermal expansion valves, compressors, filter driers and refrigerant handling. R-410A air conditioners use newer synthetic lubricants that are usually more soluble with the R-410A than the old mineral oils are with the older R-22 refrigerants. R-410A systems use mineral oils for lubrication. R-410A systems can be more reliable than R-22 systems. R-410A air conditioners and heat pumps are today's "state of the art" systems, and utilize the most current technology available for efficient and reliable operation.

R-410A was developed to replace the ozone depleting R-22 refrigerant now used in most residential and some commercial air conditioning equipment. R-410A has no ozone depletion potential but does have a higher global warming potential.

R-410A has quickly become the refrigerant of choice for use in air conditioning applications because the refrigerant delivers higher efficiency and better Total Equivalent Warming Impact (TEWI) than other choices. Make sure that if you are installing a new air conditioning system, that you specify that the new system uses R-410A. Not only is a R-410A system more reliable, but remember that R-22 use will be discontinued in 2010. An R-410A system will give you the best and most effective service for the foreseeable future.

What is a 410A 3 1/2 ton air-conditioner low pressure at 80 degrees


??? 80 degrees ??? Anything below 100 psi is going to start freezing up. 410a refrigerant is approximately 32 degrees at 100psi. Typically a 410a low pressure switch will open at 50 psi.

What type of refrigerant should be used in a Mitsubishi ms09tw 2001 air conditioner?


The answer is R410A.

Refrigerant Types in a Central Air Conditioner
There are 2 different types of air conditioning refrigerant currently used in residential cooling systems. R-22, commonly referred to a Freon and R410A, a blend considered to be more environmentally friendly, sometimes called Puron.

R410A (sometimes known as Puron), is the industry's choice to replace R-22 in central air conditioning systems. It is less reactive with the environment while having the same home cooling characteristics of R-22. R410A is not interchangeable with R-22-you choose one or the other and your air cooling equipment is designed to operate with it. When you purchase a R-410A system, a new line set is included with your central air installation as well as a new evaporator coil. Our experience with R-410A has been excellent. New cooling systems have been dependable and efficient, as well as operating quieter! R-410A is the refrigerant of the future!

Less reactive with the environment
Replaces R-22 in the year 2020
Cannot be used with R-22 systems
Quiet and dependable
Freon, R22, heat pump refrigerant
R-22 also known as Freon has been used for decades as the refrigerant in central air conditioning systems. However it has been linked to Ozone depletion and has therefore been banned from being manufactured after the year 2010. It's price will increase as the supply decreases.

Good luck,

Where do I add the new r 410a refridgerant on 2004 Pontiac vibe?


410a cannot be used in a automotive system it will cause damage to your compressor, other other a/c components.
410a is used for home use only.as a substitute for R-22
see below definition.


Although the United States Environmental Protection Agency has mandated that R-22 along with other hydrochlorofluorocarbons (HCFCs) be phased-out in the United States, few window-mounted air conditioners are available that use R-410A. However, all of the largest central air conditioning systems manufacturers in the United States offer R-410A. As an alternative to window-mounted systems, a ductless "split" system is available which uses R-410A refrigerant, and can be installed with a 3-inch hole through the wall (or window opening).[4] R-410A has replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners in Japan and Europe.
Parts designed specifically for R-410A must be used as R-410A operates at higher pressures[5] than other refrigerants. Thus R-410A systems require service personnel to use different tools, equipment, safety standards and techniques.[6] Equipment manufacturers are aware of these changes and require the certification of professionals installing R-410A systems. In addition the AC&R Safety Coalition has been created to help educate professionals about R-41-A system.
manufactures recommendations for vehicle

NOTE:
  • R-134a is the only approved refrigerant for use in this vehicle. The use of any other refrigerant may result in poor system performance or component failure.
  • To avoid system damage use only R-134a dedicated tools when servicing the A/C system.
  • Use only Polyalkylene Glycol Synthetic Refrigerant Oil (PAG) for internal circulation through the R-134a A/C system and only 525 viscosity mineral oil on fitting threads and O-rings. If lubricants other than those specified are used, compressor failure and/or fitting seizure may result.
  • R-12 refrigerant and R-134a refrigerant must never be mixed, even in the smallest of amounts, as they are incompatible with each other. If the refrigerants are mixed, compressor failure is likely to occur. Refer to the manufacturer instructions included with the service equipment before servicing.

what ton is the R-410A packaged heat pump


R-410A is a type of refrigerant and not a capacity rating of an air conditoner. 12,000 Btu's equals a 1 Ton of cooling capacity.

Compressor is out in my Goodman CK60-1C outdoor unit. Is it better to buy a new compressor or a new unit?


It is completely a matter of preference. Just having the compressor replaced with save you a couple hundred dollars, but it's well worth just throwing in a little more to get a new unit. The biggest thing right now is availability. They have stopped production of R-22 equipment and will continue to make R-22 refrigerant for 10 more years, but for the most part the R-22 equipment is getting scarce and they are bumping up the price whenever possible. The new 410A refrigerant is a better blend but runs at higher pressures and less resistant to cross contamination, which all means, if you can't find another R-22 unit, you would have to get the new 410A unit and will possibly have to replace the indoor coil and/or copper line sets to accommodate the new refrigerant blend and this means even more money. Hope this better explains your options and good luck!
