RESEARCH OF THERMAL INSULATION PROPERTIES OF THIN-LAYER INSULATING MATERIAL ON HEAT STORAGE TANKS

Abstract

The article deals with the research of thermal insulation properties of thin-layer insulating material made of hollow glass-ceramic microspheres in relation to technical building installations. Until now, there has been a lack of scientific studies describing the effectiveness of thermal insulation properties of thin-layer insulation materials on distribution systems or technical equipment. In this particular case, the insulation material was applied in a two-millimeter layer to a heat storage tank and the heat losses were compared for four models (model A - storage tank without insulation, model B - storage tank with thin-layer insulation coating made of hollow glass-ceramic microspheres, model C - storage tank with commonly used insulation supplied by the manufacturer for a specific type of storage tank, and model D - storage tank with insulating coating, including classic insulation). The measured data show that in this particular case, thin-layer insulation material cannot be a good competitor to custommade conventional thermal insulation for a given heat storage tank, however, research shows some potential in specific situations that occur in practice such as insulating of complicated pipeline routes and fittings or additional insulation of pipelines within the reconstruction of buildings in case of lack of space for the application of common insulation.
