Possibilities and limits of using natural refrigerants in air-conditioning systems for railway cars.

Author(s) : ADOLPH U.

Summary

The future of natural refrigerants like air, water, carbon dioxide, water-zeolite and propane is examined. Other than water, all of these can be used in railroad air-conditioning. Water-zeolite adsorption machines are used only for the recycling of residual heat. Air installations with sufficient capacity are possible, but their TEWI would be too high, due to a low COP. Carbon dioxide and propane, on the other hand, are quite promising. For the former, components will have to be optimized so as to reach the necessary TEWI and COP values. For the latter, a separate circuit needs to be designed, so that safety standards can be met.
