The preformance of large compressor driven heat pumps - System simulations

Other conference contribution, 1983

In Sweden there is today a very high interest for large heat pumps in group centrals, district heating systems, and industry. Due to the current price ratios between electricity and oil (apprax. 1:1), practically all are electrically driven. However, the electricity prices in Sweden will probably increase considerably in a l0-year period, which will make e.g. diesel driven systens interesting. Therefore, a big project, sponsored by The Swedish Council for Building Research, has been carried out, in which these two types of heat pumps have been conpared technically and economically. It has been made as a cooperation between the Chalmers University (technical part) and the Battelle Institute, Frankfurt (technicoeconomic comparisons). This paper will deal only with results fran the technical part. In order to investigate various technical parameters, a big computer program was developed. After the presentation of this, sane of the results from it will be discussed.
