Supermarket refrigeration systems with natural refrigerants

Influence of chlorofluorocarbon refrigerants on climate warming has become in recent years a serious concern of both scientists and state officials in different countries of the world.
The main directions of solving this problem at present are measures aimed at reduction of refrigerant leakage from refrigeration systems, reduction of its volume in the system, as well as gradual transfer of refrigeration equipment to operation with such natural refrigerants as ammonia, hydrocarbons, carbon dioxide. This review briefly highlights different aspects of using these refrigerants in supermarket refrigeration systems.
