Numerous previous studies have focused on the characteristics of capillary tubes, considering liquid refrigerant flow at the capillary tube inlet and the condensation of refrigerant. Air can enter in the refrigeration plant when any part of the system pressure drops below atmospheric pressure. Refrigeration is the process by which heat (thermal energy) is transferred from a low temperature body to a high temperature body and the heat that is removed from the low temperature body accounts for the refrigeration effect. The storage life of fresh perishable foods such as meats, fish, fruits, ...

Effects of refrigeration and alcohol on the load of Aeromonas hydrophila in oysters. Because of these adverse effects, the vapor compression refrigeration cycle is designed such that the refrigerant reaches a subcooled or saturated liquid state at the capillary inlet. The work of compressor and COP values tend to increase when the system incurs the superheating. Freon is the trade name for a class of chemicals called chlorofluorocarbons, or CFCs, used primarily in refrigeration and air conditioning.

(Reference 4) Refrigerants are toxic to the heart and can result in heart attacks, high blood pressure and abnormal heart rhythms leading to circulatory collapse, according to the Environmental Health article. To know more read: Shocking Effect of a refrigerator and how to protect your family health The implementation of solid-state refrigeration requires that the refrigerants should possess not only remarkable caloric effect but also wide working temperature region. Members of the bacterial genus Aeromonas are widely distributed throughout the environment and are readily cultured from a variety of foods.
