AçıklamaHEAT PUMP SYSTEMSHISTORY First heat pump aplications are considered in the 1920 s with restatements of and improvements on Thomson paper by Krauss and Morley and although there where no heat pumps as such in existence it was possible to examine their feasibility from analysis of the per formance of the rapitly increasing amount of refrigeration equipment which was being installed. This was done by Haldane, who analysed data from a selection of refrigerating plant operation beween 1981 and 1926. The first major heat pump installation in Europe was commisioned during the period 1938 – 39 in Zurich. This unit, which used river water as the heat source, utilised a rotary compressor with R12 as the working fluid. Used to heat the Town Hall, the output of the Zurıch heat pump was 175 KW, delivering water at a temperature of 600 for space heating. A thermal storage system was incorporated in the circuit, in the form of a calorifier which could be boosted by electric heating at periods of peak demand.
