Future vision of heat pump technology and global environment.

Author(s) : MAKISE Y.

Summary

Heat pumps is one of the key technologies to achieve sustainable development and to solve problems concerning energy and environment simultaneously. Refrigerants for heat pumps can be replaced by alternative refrigerants as HFC which have an ozone depletion potential of zero. Heat pump efficiency can be made two times the current efficiency by developing technology such as Lorentz cycle using non-azeotropic refrigerants. Owing to the development of high density heat transfer technology, triple effect absorption heat pumps and high efficiency turbo type heat pumps, the total system making effective use of unused energy can be developed to realize energy savings. In order to develop efficient utilization of energy in the future by establishing new infrastructure such as eco-energy urban systems, the use of high efficiency type electric heat pumps and development of chemical heat pumps utilizing hydrogen absorbing alloys should be promoted. It is the duty of advanced nations to rapidly transfer to developing nations various environmental protection technology, while promoting ozone layer protection and global warming prevention.
