Influence of Heat Source Location on Surface Temperature Distribution of the Indoor Side of External Walls in an Uninsulated Apartment in Warsaw during the Heating Season

Abstract

This article presents the influence of the heat source location to surface temperature distribution of the indoor side of external walls in an uninsulated apartment in Warsaw during the heating period. The apartment is located in a multi-family residential building. This building has never been thermomodernized and therefore it is highly energy-consuming. In 2016, an air-to-air heat pump was installed in the apartment and replaced the existing heat source, a dual-function gas boiler. The device is used both for heating the apartment during the heating period and cooling it during the summer. Such a system works particularly well in non-insulated objects, in which the partition’s internal surface temperature changes dynamically as the outside temperature changes. This article describes the results of the thermovision test of the walls of this flat. The surface internal temperature distribution on the selected three walls was examined under different atmospheric conditions while maintaining similar internal conditions.
