Building environment design - Design, dimensioning, installation and control of embedded radiant heating and cooling systems - Part 4 : dimensioning and calculation of the dynamic heating and cooling capacity of Thermo Active Building Systems (TABS)

ISO 11855-4:2012 allows the calculation of peak cooling capacity of Thermo Active Building Systems (TABS), 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 the chiller size, fluid flow rate, etc.ISO 11855-4:2012 defines a detailed method aimed at the calculation of heating and cooling capacity in non-steady state conditions.

Heating systems in buildings - Design of embedded water based surface heating and cooling systems - Part 3 : optimizing for use of renewable energy sources

Le présent document vise à fournir un guide pour la conception promouvant le recours à des sources d'énergie renouvelables et à proposer une méthode pour l'utilisation de systèmes thermoactifs (TABS). Le présent document spécifie une méthode pour calculer : la puissance frigorifique de pointe d'un système thermoactif sur la base des apports de chaleur ; la demande d'énergie coté eau (système) à utiliser pour le dimensionnement du système de refroidissement. Les méthodes du présent document s'appliquent aux systèmes intégrés dans la construction (murs, planchers ou plafonds) sans plenum ouvert. Les méthodes du présent document ne s'appliquent pas aux panneaux, ou poutres de plafond chauffés ou réfrigérés.

Building environment design - Embedded radiant heating and cooling systems - Part 4 : dimensioning and calculation of the dynamic heating and cooling capacity of Thermo Active Building Systems (TABS)

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.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
