Summary

The amount of energy consumed by refrigeration and air conditioning reaches about 15% of the domestic consumption. However, discharged refrigerants used in equipment and exhausted carbon dioxide to drive the equipment are related to environmental and energy problems. Especially, depletion of ozone layer and global warming are sounded as serious global problems. There is an important relation between refrigeration cycle and refrigerant, so the cycle performance changes depending on the thermophysical properties of the refrigerant. To develop equipment that alleviates the environmental and energy problems, a suitable refrigerant must be selected. In this article, the current state of the refrigerants is introduced. And the future of refrigeration and air-conditioning equipment are considered from the viewpoint of thermophysical properties of the refrigerants.
