本文件允许根据热增益（如太阳能增益、内部热增益和通风）计算热激活建筑系统（TAB）的峰值冷却能力，并计算水侧的冷却功率需求，以确定冷却系统的尺寸，包括冷却器尺寸、流体流速等。 本文件定义了一种详细的方法，旨在计算非稳态条件下的加热和冷却能力。

This document allows the calculation of peak cooling capacity of Thermo Active Building Systems (TABS) – Type V according to ISO 11855-1, based on heat gains, such as solar gains, internal heat gains, and ventilation, and the calculation of the cooling power demand on the water side, to be used to size the cooling system, as regards, e.g. the chiller size, fluid flow rate. This document defines a detailed method aimed at the calculation of heating and cooling capacity in non-steady state conditions.
