该欧洲标准规定了输入和输出数据的水平,并且规定了在恒定和/或浮动温度下单个房间的显热冷却负荷的计算方法所需的边界条件,考虑到峰值冷却负荷的极限系统。它包括计算方法的分类方案和通过计算方法满足的标准,以符合本欧洲标准。 本欧洲标准的目的是验证以下计算方法: 评估设备选型和冷却系统设计的最大制冷负荷; ï,¾评估系统冷却能力降低时的温度曲线; ï¾提供用于评估减轻负载的最佳可能性的数据; ï允许分析系统设计,操作和控制所需的部分负载。 验证程序用于检查房间显热平衡模型,同时考虑: ï,¾外表面热平衡; ï,通过建筑物信封的传导; ï,结构的热质量的影响; ï,¾内表面热平衡; ï,¾空气热平衡; ï¾热平衡溶液法。 所有其他方面由固定边界条件或输入数据给出
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 either by fixed boundary conditions or by input data and are not in the focus of the model validation. It is assumed that for all these other matters e.g. embedded heating and cooling systems, prescriptive models have to be used according to existing European Standards. Informative Annex A gives a simplified method for cooling load calculation.
