ISO 11855-4:2021 Scope
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.
