【 摘 要 】

The contemporary building sector needs new technologies for reducing the energy consumption in heating and cooling processes used in building interiors. These solutions should be integral to ensuring the comfort of using such premises. Phase change materials (PCM) that absorb, accumulate and return large amounts of heat energy as part of their phase change temperature meet such needs. These materials can absorb excess heat in overheated premises at times when the temperatures are high, during long hours of sunshine in summer time, or from internal sources such as working machinery or office equipment. The stored heat energy, due to the postponement, will be transmitted to the room at a later time, usually in the evening. Thanks to these properties, it is possible to provide better utility conditions in building interiors. This article describes the test results of selected properties of PCM modified materials applied in floor systems that are used in premises where they are subject to significant overheating. The analysis took into account the impact of a phase change material on the mechanical and physical properties of the tested material solutions. This modification is intended to provide better thermal comfort in the rooms, while the use of PCM has a beneficial effect on reducing the temperature fluctuations in the premiseswhere it is used.
