Dataset on Trombe wall application in a factory building

Abstract

An experimental passive solar thermal transmission wall (also known as Trombe wall) prototype was installed on a factory building wall in Kalnciems, Latvia to carry out temperature measurements at different representative locations in order to evaluate Trombe wall's potential to be used as a secondary space heating source. The average winter temperature in Kalnciems is 0.7 °C which stipulates the need for space heating (6-7 months a year). The dataset collection spanned from March 2022 through July 2023, enabling to acquire data over meaningful timeframe, as well as one full year cycle. Exploring Trombe wall technology in a cold climate setting aimed to examine its potential to curtail space heating energy consumption. The experimental Trombe wall prototype was closely monitored, and showcased substantial temperature increase during sunlight hours, emphasizing its potential to be used as a secondary heating source in industrial settings. The Trombe wall structure also demonstrated a sufficient internal temperature gradient (Δt between 1.5 and 5.0 m level a.g.) and generated rather substantial energy output, which is especially important for regions with moderate and cold climates. Enlarging and refining these systems could significantly reduce costs associated to space heating in industrial settings. Recommendations include investigating enhanced air circulation and filtration for improved functionality and user comfort.
