Abstract
The invention relates to a method for operating a variable-speed refrigerant compressor () for cooling a cooling volume () of a refrigeration system () that does not have its own control unit, wherein the refrigeration system () comprises at least one thermostat () for directly or indirectly monitoring a temperature state of the cooling volume () and wherein the rotational speed behavior of the refrigerant compressor () during a cooling cycle is controlled by means of a preset closed-loop rotational speed control saved in an electronic control device () of the refrigerant compressor (), based on at least one predefined parameter, in that the at least one predefined parameter is monitored with respect to an over- and/or undershooting by a current parameter of a current cooling cycle, and relates to an electronic control device () for controlling the cyclical operation of a variable-speed refrigerant compressor. In order to enable an adaptation of the preset closed-loop rotational speed control performed by the electronic control device () of the refrigerant compressor () to the refrigeration system and/or ambient conditions, it is provided according to the invention that an additional temperature independent from the temperature of the cooling volume () is measured and the at least one predefined parameter is changed as a function of the additional temperature.
