Abstract
1. A method of controlling a compound refrigerating plant comprising a plurality of compressors and at least one fa for the discharge of the heat of liquefication, wherein the air volume flow of the fan or fans is changed in dependence upon the suction air temperature and the refrigerating capacity, characterised in that the suction air temperature Ta and the liquefication pressure Pc are measured and a theoretica value Pc,s of the liquefication pressure is set, which is dpendent upon the air suction temperature.
