EXTERNAL COOLING SYSTEM OF SUPERCOMPUTER AS SOURCE OF ACOUSTIC NOISE
The paper is devoted to methodology and results of experimental researches of noise level generated by the blocks of the cooling system of the supercomputer located on surrounding territory. The measured noise level at a distance of 30 m from the blocks of the cooling system is shown to exceed the permissible levels of sound pressure in the surrounding area. It is noted, that during the winter period at presence of a snow cover there is an additional attenuation of a level of sound pressure approximately on 4-5 dBA. Data on a choice of designs of windows with ventilating devices which provide necessary decrease of noise level for rooms in buildings located near cooling system blocks are given.
