Abstract
Human activity has caused the intensive saturation of the Earth's atmosphere with ozone-dangerous and greenhouse gases, significantly changing its heat balance and gas composition. Predicted global warming and ozone layer destruction endanger the biosphere. The Montreal and Kyoto protocols, the result of the extensive research by the scientific community, banned production and limited the use of many ozone-hazardous and greenhouse-gas refrigerants, which were widely used in ship refrigerating machines before. However, the problem of choosing attractive energy-efficient and environmentally safe refrigerants now raises more questions than provides solutions. At present, an attempt is being made to develop a model for estimating and ranking refrigerants based on numerical complex indicators of attractiveness.
Keywords: ozone, greenhouse effect, heat exchange, refrigerant (Bi), refrigerating machine, energy efficiency, environmental safety, complex index of attractiveness.
