A refrigerant is the working fluid used in refrigeration and air-conditioning systems to absorb heat from a low temperature region and reject it to a high temperature region during the refrigeration cycle. The selection of a suitable refrigerant is very important for the efficient, safe and economical operation of refrigeration systems. A good refrigerant should possess several desirable thermodynamic, physical, chemical and environmental properties. One of the most important properties of a good refrigerant is a low boiling point. The refrigerant should be able to evaporate at a temperature lower than the temperature of the space or substance that needs to be cooled. This allows the refrigerant to absorb heat effectively during the evaporation process. At the same time, the refrigerant should have a moderate condensing pressure so that it can easily condense at normal atmospheric or cooling water temperatures without requiring extremely high pressures. A high latent heat of vaporization is another desirable property of a refrigerant. Latent heat of vaporization is _____ __________ ________ ________ ___ _____ ______ ______ _____ ____.
