    Abstract: The invention relates to a method for controlling a compressor of a refrigeration system, said compressor having a motor, wherein the temperature of the cooling point is controlled by means of switch-on and switch-off operation of the motor if the temperature in the compressor exceeds an upper temperature threshold and the temperature of the cooling point is controlled by means of continuously switched-on operation of the motor as soon as the motor has cooled down to a lower temperature threshold, wherein the control system converts a manipulated variable corresponding to the cooling demand of the cooling point into a switching signal for a valve, which switching signal causes clocked opening and closing of the valve, or a frequency converter controls the refrigerant flow through the compressor by controlling the voltage and the frequency of the motor, in that the frequency converter converts a manipulated variable corresponding to the cooling demand of a cooling point into a voltage and a frequency for the motor.

    Abstract: In a lubricant-cooled gas compressor (10) the temperature of separated lubricant returned to the air-side (11) is monitored by a thermostatically controlled restrictor valve (22) which minimises the flow of returned lubricant when temperature is low as on start up or when running on reduced load but increases the flow as the lubricant temperature increases. This will minimise the condensation of water from indrawn air when the temperature of the compressed air is too low to retain the water as vapour, so that the returned lubricant is contaminated with water which will damage the moving components of the air-end.
