Method for operating air-conditioning units and apparatus for carrying out the method

摘要

A method for operating air-conditioning units is claimed, in particular for the air-conditioning of rooms for data processing systems, wherein air, such as outside air, exhaust air or a mixture of outside air and exhaust air is led passed the heat exchanger of a cooling set comprising a compressor or 3-way modulation valve and is supplied by means of a fan to the room to be air-conditioned as supply air. According to the invention, during light-load operation the cold output of the cooling set is reduced and as a function of the cold output the air output of the fan is reduced (Fig. 1). <IMAGE>
