Arlington, VA (February 3, 2014) – The Alliance for Responsible Atmospheric Policy (Alliance) submitted a petition for rulemaking to Environmental Protection Agency Administrator Gina McCarthy on Friday, January 31, 2014. The request seeks to include hydrofluorocarbons (HFCs) under the provisions of Title VI, Section 608 of the Clean Air Act intended to reduce refrigerant gas emissions. Including HFCs under Section 608 would reduce the emissions of these important compounds that provide safe and effective refrigeration and air conditioning services but are also greenhouse gases. Section 608 already includes requirements for chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs).
The Alliance estimates that the inclusion of HFCs under Section 608 could reduce HFC emissions by 15-20% in the United States. The primary goal of Section 608 is to minimize the loss of refrigerant to the atmosphere by improving the practices utilized during the servicing of air conditioning and refrigeration appliances. It sets certain leak and recovery standards and requires enhanced certification of equipment and technicians.
ComfortStar mentions the following reasons for approving R421A as the only acceptable R22 alternative refrigerant for use in their equipment-
-R421A is an environmentally friendly non ozone depleting replacement for R22
-R421A can replace R22 without modification-
-R421A no hydrocarbons such as butane, and is rated “A1” by ASHRAE
-R421A is non flammable and rated A1 by ASHRAE
-R421A can be used with Mineral, AB, or POE oils*
-R421A is comparable to R22 in terms of performance and pressures, approximately 1% higher at 95°F

*If there is a vertical height difference of 20 feet or more between the evaporator and condensor, the system must be converted to POE.
