GAS R**4A 

Unlike alkyl halide refrigerants that contain bromine or chlorine, R***0A (which contains only fluorine) does not contribute to ozone depletion and is therefore becoming more widely used, as ozone-depleting refrigerants like R**2 are phased out.

Its main application is new plants for medium and low refrigeration temperatures. The theoretical cooling capacity is 5% lower than the R***2 at evaporation temperatures equal to **0ºC. The coefficient of performance (COP) is between about 5 and 8% less than with R***2. If overheating increases, the COP of the R***4A may be higher than that of R***2. In the case of retrofits of R***2 and its HCFC substitutes (R***8A, DI**4), it is necessary to eliminate *5% of original mineral oil or alkylbenzene, replacing it with an oil based on polyol esters, change the dryer filter, expansion valve, rubber O-rings with plastic ones and in some cases oversize the condenser. In case it is used as a retrofit of the R**2, it will also be necessary to replace the safety valves and other calibrated elements according to the pressures of R**2.
