NBR17199 DE 09/2025

Esta Norma estabelece os procedimentos de ensaio para caracterizar o desempenho de sistemas de aquecimento solares de água domésticos, operados sem sistemas de aquecimento de água auxiliares, e para prever o desempenho anual em qualquer condição climática e operacional, apenas para consumo noturno. This Standard establishes test procedures for characterizing the performance of solar domestic water heating systems operated without auxiliary boosting, and for predicting annual performance in any given climatic and operating conditions, but only for an evening draw-off. A “black box” approach is adopted which involves no assumptions about the type of system under test; the procedures are therefore suitable for testing all types of systems, including forced circulation, thermosiphon, freon-charged and integrated collector-storage systems.
