Trend in heat gains from office equipment

Abstract

The paper is focused on the trend in heat gains from PCs and monitors as widely used IT equipment. The study included literature review and measurements carried out by the authors of the paper. Updated set of recommended values for PCs and monitors is proposed to replace the ASHRAE recommendations based on the measurements carried out in 1990s. The updated values of typical heat gains are determined from the maximum heat gains measured with three-minute interval. The typical heat gains should be used with respect to the design purpose.
