WebFeb 9, 2010 · However, the specific volume of R134a is somewhat more than R12, thus for the same amount of the refrigerant, the volume occupied by R134a is more than R12. Hence the increase in the refrigerating effect of R134a is offset by increase in its specific volume. Thus though R134a charged in the retrofitted systems should be about 5 to 10% lesser ... http://www.ethermo.us/ShowDetail38.htm
