Overview
The challenge in refrigeration (and air conditioning, etc.) is to remove heat from a low temperature source and dump it at a higher temperature sink. Compression refrigeration cycles in general take advantage of the idea that highly compressed fluids at one temperature will get colder when allowed to expand.An ideal refrigeration cycle looks much like a reversed Carnot heat engine or a reversed Rankine cycle heat engine. Liquefied fluid leaves the condenser and enters the expansion valve. This valve reduces the pressure level and meters the flow so that as much working fluid leaves the compressor as enters the evaporator.
By providing additional subcooling prior to the expansion valve Researchers at the University of Maryland have improved the refrigeration capacity of a vapor compression refrigerator cycle by 17% and the coefficient of performance by 6%.
