Abstract
The present invention is directed to a method for controlling the outlet temperature of an oil injected compressor or vacuum pump comprising a compressor or vacuum element provided with a gas inlet, an element outlet, and an oil inlet, said method comprising the steps of: measuring the outlet temperature at the element outlet; and controlling the position of a regulating valve in order to regulate the flow of oil flowing through a cooling unit connected to said oil inlet; whereby the step of controlling the position of the regulating valve involves applying a fuzzy logic algorithm on the measured outlet temperature; and in that the method further comprises the step of controlling the speed of a fan cooling the oil flowing through the cooling unit by applying the fuzzy logic algorithm and further based on the position of the regulating valve.
