Australia's energy consumption. The MEPS (Minimum Energy Performance Standards) levels are mandatory requirements for certain products (including air conditioners, refrigerators & freezers) manufactured in, or imported into, Australia and are specified in the relevant Australian Standards. Everyone has a role to play in reducing greenhouse gas Credit: AP Photo/Jenny Kane. In what officials call a key step to combat climate change, the Environmental Protection Agency is sharply limiting domestic production and use of hydrofluorocarbons
Although freon is generally considered to be a fluorocarbon of relatively low toxicity; significant toxic effects may occur when significant over-exposure occurs. For example, contact of the skin with the cold liquid can cause frostbite and defatting and contact with the eye may result in irritation.

The race to find an alternative refrigerant for R-410A is on. After all, 410A has to be one of the greatest used, if not the greatest, refrigerant in the world. Everyone needs a cool house and most of the time they’re either using R-22 or R-410A. Finding an alternative has proven difficult though as there has been no perfect match so far.

However, R-12 damaged the ozone layer, causing governments to issue a ban on its use in new refrigerators and air-conditioning systems in 1994. The less harmful replacement for R-12, R-134a (tetrafluoroethane), has been in common use since 1990, but R-12 is still found in many old systems today.
Because of its reduced global warming potential (GWP), R-454B is intended to be an alternative to refrigerant R-410A in new equipment. R-454B has a GWP of 466, which is 78 percent lower than R-410A's GWP of 2088. R-454B is non-toxic and mildly flammable, with an ASHRAE safety classification of A2L. In the United States, it is expected to be This eco-friendly refrigerant is ozone-friendly but has a moderately high Global Warming Potential of 2088. Price: $6,550/kg. R-413a. R-413a is a zeotropic blend of R-218, R134a, and R600a. It is an HFC refrigerant designed to replace R12 for direct expansion air conditioning systems and medium to high-temperature refrigeration systems. HVAC Freon recharge costs $100 to $320 for R410A refrigerant or $180 to $600 for R22 Freon. An HVAC system should never need more Freon unless the system has a leak or the recharge is part of a repair. Hire a licensed HVAC technician to locate and repair any leaks before refilling the refrigerant. AC contractor using R22 freonfor home AC recharge. Freon is an extremely toxic substance and studies have shown just how much it can destroy the ozone layer that protects us from harmful radiation. As a result, the EPA began scaling back on production levels to try and lessen the impact on the environment while new refrigerants were in development. .
