Freon 410A is a zero ozone depletion potential (ODP) refrigerant for use as a replacement for HCFC-22 in a variety of new equipment applications. Freon 410A is a non-azeotropical blend consisting of HFCs Freon 32 and Freon125. Freon 410A is a suitable replacement for new applications which used to operate with HCFC-22. Many refrigeration and air conditioning manufacturers have equipment specifi cally for Freon 410A. Applications where Freon 410A might be used include air-conditioning, chillers and commercial refrigeration. Due to the higher capacity and pressure of Freon 410A, it is not recommended as a retrofi t to existing Freon 22 systems. Mandatory changes would need to be made to existing equipment to accommodate the higher capacity and pressures of Freon 410A. Included in these changes would be expansion valves, compressors, condensers, and other high side components. In situations where a retrofi t would need to be performed, Freon 407C would be recommended due to it’s similarity to Freon 22.
For new installations, with properly charged equipment, line sizes, etc. Freon 410A has shown to have a 5-6% higher Energy Effi ciency Rating (EER) than Freon 22. Freon 410A also has a higher capacity and pressure than Freon 22, allowing for the design of smaller, more compact air conditioning equipment. Freon 410A, as with other HFC refrigerants, requires polyolester (POE) lubricant to ensure complete miscibility between oil and refrigerant. Manufacturers of Freon 410A equipment will supply equipment with the proper lubricant already charged.
