Abstract

A method for operating a refrigeration system in order to perform temperature control of a closed volume is disclosed. The refrigeration system comprising a compressor, a condenser, an expansion device and an evaporator connected in series in a refrigerant flow path. The refrigeration system further comprises one or more fans arranged to cause a flow of air across the evaporator.The compressor is controlled by switching the compressor on or off in accordance with a measured temperature, Tsup, of air which has passed across the evaporator and is being supplied to the closed volume, and in order to achieve a set point temperature, Tset, in the closed volume. During this a compressor switching pattern is determined.Temperature fluctuations inside the closed volume are minimized, and energy is conserved.
