Assessment of heat gain from server equipment

Blade server architecture is widely used as server hardware for datacenters. This article proposes methods for calculating thermal radiation from blade servers at the design and operation stages. In particular, the method for calculating heat gain at the design stage can be used to select equipment for the air conditioning system. The method for calculating heat gains at the operational stage with the current load of IT equipment can be useful for analyzing the operation of existing air conditioning systems or analyzing the energy efficiency of IT equipment in a specification.
