Air cycle technologies for building services.

Type of article: Periodical article


Studies in the UK concern the use of air-cycle refrigeration for building services. The results indicate that in simultaneous heating and cooling situations economies might be gained over conventional plants. An advantage over vapour compression heat pumps is that high water temperatures are obtained with no efficiency loss. The studies assume reliable turbocompressors are available at reasonable cost. Also air-to-air heat exchangers can be improved and variable-speed, switched reluctance motors or suitable gas turbine drives are developed. Air, as a refrigerant, is ecologically safe and greenhouse gas emissions would be less or no more than from conventional systems. D.W.H.
