Scientific Refrigeration

Scientific refrigerators, often known as pharmaceutical refrigerators or lab refrigerators, are designed to preserve contents against temperature fluctuations higher or lower than those advised by content makers. The process of Scientific Refrigeration starts where the high-pressure receiver in which the liquid refrigerant is kept. The liquid goes via a thermal expansion valve, which causes a pressure drop. Some of the liquid evaporates as the pressure is reduced, causing the remaining liquid to cool.
