Major modification required to produce temperature of - 200?C in a vapour compression refrigeration system using Freon 12 as refrigerant, is

Question

TuteeHUB · Accepted Answer

Insulation should be capable of withstanding such low temperatures

TuteeHUB · Answer

Condenser capacity must be increased to handle the refrigerant

TuteeHUB · Answer

Size of compressor required would be large to handle volumes of vapour

TuteeHUB · Answer

Compression ratio has to be restricted till stronger body of compressor is needed

TuteeHUB · Answer

Freon 12 cannot be used for such low temperatures
