Abstract (en)

A method of controlling a compressor driven vapour compression heat movement system in which a common compressor system (2) heats or cools a plurality of load units (4, 8) and is operated in cycles each of which include a compressor system higher capacity period and a compressor system lower capacity period, characterised in that the lower capacity period is made sufficiently long that when the compressor system (2) is switched to the higher capacity a majority of the load units (4, 8) are demanding heating or cooling and that the higher capacity period is made sufficiently long that when the compressor system (2) is switched to lower capacity one or more of the load units (4, 8) have had their heating or cooling demand satisfied.
