Trading more expensive auto air conditioning for lower car fuel mileage ?


Repairing 2013 car air conditioning systems is going to get much more expensive due to new Environmental Protection Agency policies that encourage the use of a new cooling refrigerant. The EPA has developed this policy in an effort to reduce harmful greenhouse gas emissions that have been linked to global warming.

When automotive air conditioning systems were introduced, Freon R-12 refrigerant was used for cooling. However, R-12 is one of the most harmful greenhouse gases when released into the atmosphere,During his confirmation hearing, Thomas explained that he would identify with defendants: "So I can walk in MBT shoes Tariki man and I could bring something different to the court." It is now clear that to Thomas, those remarks did not mean he necessarily would empathize with defendants.Israel's foreign minister said Tuesday that a U.S.-born Israeli arrested in Egypt on espionage charges is not a cheap wireless spy cameras and expressed hope the case would soon be resolved.Since Mubarak's ouster, Egypt's military rulers have often warned. according to the EPA. In 1993,A refrigerant is a substance used in a heat cycle usually including automobile manufacturers were required to convert to R-134a, which was viewed as an improvement. Conversion kits were available for older automobiles, trucks, tractors and combines using R12.

Now, the EPA has determined that R-134a also is a harmful emission and is trying to phase it out. However, the EPA is not dictating the use of the new refrigerant R-1234yf as it has done in the past. Instead, the EPA is providing an incentive and encouraging adoption by giving credits to automobile manufactures for meeting the stricter Corporate Average Fuel Economy (CAFE) mileage standard of 35.5 miles per gallon.

In essence, car manufactures will be allowed to sell cars with poorer fuel mileage if they upgrade air conditioning systems to R-1234yf. It is all based on greenhouse gas (GHG) emissions, which are a priority of the Obama administration. The administration believes GHG emission reductions will be greater with the new refrigerant than by burning less fuel and meeting the 2013 CAFE target.

The switch to R-1234yf will not be cheap. First, current wholesale prices for this new refrigerant hover around $45 per pound, which is 10 times the price of R-134a. In addition, R-1234yf is less efficient. To get the same level of cooling in automobiles, manufacturers will have to install a new device that will act as a heat exchanger to improve system performance. The average cost per car is expected to be $100 per unit.
