Inter-Seasonal Heat Storage in Low Energy House: from Requirements to TESS Specifications

摘要

This paper aims at providing sizing information concerning a thermal energy storage system (TESS) in the case of a low energy consumption building (＜ 50 kWh/m~2·y). Numerical simulations for a reference individual building were run for twenty-three different cities in Europe. As power supply is the limiting factor in most of the TESS, results focuses on design power estimation. A clear correlation between power demand and beating degree hours (HDH) is presented. But as the design of a TESS based on maximum power is too ambitious, the analysis goes further. It gives the distribution of sorted power demand values as a function of HDH in the form of a power sizing chart. The purpose of this chart is to provide specification requirements for the sizing of a thermal storage system intended to partially cover power demand of a low energy residential house.
