Abstract

The embodiment of the invention discloses a fan rotating speed control method and belongs to the technical field of air conditioners. The method is applied to equipment using a compressor for temperature adjustment and comprises the steps that when the compressor is confirmed to finish starting, a set rotating speed of a fan is confirmed out of a plurality of preset gradational rotating speeds according to the first ambient temperature, compressor air exhaust pressure and compressor air inlet pressure, and the fan is controlled to run according to the set rotating speed. When a centrifugal compressor is controlled adopting the fan rotating speed control method, appearance of surge and noise due to the compressor pressure ratio is too high can be avoided. The embodiment of the invention further discloses a fan rotating speed control device and a computer readable storage medium.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a method, device and computer-readable storage medium for controlling the rotational speed of a fan. Background technique [0002] In air-cooled or evaporative-cooled chillers, the conventional control method is to detect the compressor exhaust pressure when the fan is running, and control the fan speed according to different exhaust pressures. Especially in the control process of the centrifugal compressor, if the above method is used to control the operation of the fan, the pressure ratio of the compressor is likely to be too high, which will cause the compressor to surge and generate noise. Contents of the invention [0003] An embodiment of the present invention provides a method for controlling the rotational speed of a fan. When the method is used to control a centrifugal compressor, surge and noise due to an excessively high pressure ratio of the compres...
