“…Konieczność uwzględnienia masy termicznej ściany w ocenie jej efektywności energetycznej została zidentyfikowana i opisana w literaturze za pomocą współczynników charakteryzujących rozkład oporności cieplnej i masy termicznej w przegrodach wielowarstwowych [1]. Kolejnym parametrem, pozwalają-cym ocenić dane rozwiązanie konstrukcyjne z uwzględnieniem zarówno pojemności jak i przewodności cieplnej, jest współczynnik tłumienia temperatury [2].…”

Celem artykułu jest wyznaczenie stabilności termicznej komponentu izolacyjnego modyfikowanego warstwą MFZ. Analiza została przeprowadzona w stanie niestacjonarnym na podstawie rozkładu temperatury w przekroju ściany. Zaprezentowane zostały wyniki obliczeń przeprowadzonych dla dwóch wprowadzonych przez autorów, zmodyfikowanych współczynników tłumienia (ZWT i ZWWT), pozwalających w pełni określić efekt zastosowania warstwy MFZ na stabilizację termiczną przegrody zewnętrznej. Współczynniki określono na podstawie analiz symulacyjnych w Polskich warunkach klimatycznych. Porównanie wyników uzyskanych dla przegrody referencyjnej oraz modyfikowanej warstwą MFZ pokazuje różnice w wartościach ZWT od kilku do kilkunastu procent zależności od analizowanego dnia wybranego okresu czasu.Słowa kluczowe: dynamika cieplna, symulacja komputerowa, ściana zewnętrzna, sezon ogrzewczy, budynek zero-energetyczny

Abstract-In hot summer and cold winter zone of China, the intermittent and compartmental heating method of air conditioning is widely adopted. The intermittent heating method makes the heat storage in walls become the main way for heat dissipation. The compartmental heating method results in a large amount of heat loss not only in exterior walls, but also in interior walls. Based on this heating method, a series of experiments were conducted in Shaoxing, a typical city in the hot summer and cold winter zone. The results showed that, internal insulating method for exterior wall could save more energy than external insulating method by reducing the wall heat storage amount. Besides, both the exterior walls and interior walls should be insulated as the heat loss in interior walls accounts for a large proportion of the total heating load and whether the adjacent room heating or not has little effect on reducing it.

“…They showed that for intermittently operated buildings, 11% energy savings are obtained when the insulation is placed at the inner surface of walls compared to placing it at the outer surface. Kossecka and Kosny [3] used DOE-2.1E to investigate the influence of insulation position within exterior walls on heating and cooling loads in a continuously used building. The walls are composed of heavyweight concrete layer of constant thickness of 0.152 m and insulation layers of constant thickness of 0.102 m. The insulation position is varied within the wall.…”

The energy efficiency design of the exterior wall in the buildings of the hot summer and cold winter zone of China should consider the heat prevention in summer and the heat insulation in winter. The self-insulation of the exterior wall is a more feasible design to satisfy the energy efficiency of buildings in the zone. However, the systematic research is urgently needed for the self-insulation of the exterior wall in the hot summer and cold winter zone of China. The paper tested the thermal performance of the common non-clay materials such as shale sintered hollow brick, sand autoclaved aerated concrete block, etc. by means of indoor experiments. The energy efficiency effect of the common materials was verified using dynamic calculation soft PKPM and several constitutions of exterior wall with different main bricks and insulation materials on the heat bridge were simulated, too. Besides, the tests of the thermal performance of exterior wall in real constructions were carried out to testify the practical effect of the recommended constitutions of exterior wall with different main bricks and insulation materials on the heat bridge. The conclusions are: the physical and thermal properties of the six non-clay wall material are better than the clay porous brick; the thermal performance of the non-clay brick can be improved obviously through the rational arrangement of the holes; shale sintered hollow brick after increasing the holes and rationalizing the hole arrangement and sand autoclaved aerated concrete block are recommended for buildings in the hot summer and cold winter area of China. The dynamic calculation results show that the thermal performances of the non-clay materials are all satisfied with the energy efficiency; The heat transfer coefficient of the exterior wall with composition ③, in which the main wall was sand autoclaved aerated concrete block and the material on the heat bridge was sand autoclaved aerated concrete plate, is the smallest among the three recommended compositions.
