New refrigerants will be used for windows, sir conditioning systems, heat pumps, and chillers starting Jan,1, 2010. Rebates are offered to replace the old refrigerants are old systems are not required to be thrown away. Freon 22 has been used for refrigerant for years, but when it is released into the atmosphere, it destroys t he ozone layer. The new coolants will be built better, greater energy efficiency, save money, and have lower leaks. however, the new systems will still contribute to global warming since it distributes heat into the atmosphere.
The new refrigerents are definitely more environmentally friendly. Schools, offices, and homes should get rid of their old systems and relpace them. I think the rebate is also helpful in helping people afford the replacement. I think Roxbury can use some upgrades.
