Abstract

This European Standard sets out the level of input and output data, and prescribes the boundary conditions required for a calculation method of the sensible cooling load of a single room under constant and/or floating temperature taking into account the limit of the peak cooling load of the system. It includes a classification scheme of the calculation method and the criteria to be met by a calculation method in order to comply with this European Standard. The purpose of this European Standard is to validate calculation methods used to: ? evaluate the maximum cooling load for equipment selection and cooling system design; ? evaluate the temperature profile when the cooling capacity of the system is reduced; ? provide data for evaluation of the optimum possibilities for load reduction; ? allow analysis of partial loads as required for system design, operation and control. The validation procedure is used to check the room sensible heat balance model, taking into account: ? the external surface heat balance; ? the conduction through the building envelope; ? the effect of the thermal mass of the structures; ? the internal surface heat balance; ? the air heat balance; ? the heat balance solution method. All other aspects are given eit
