В статье представлены результаты математического моделирования и экспериментального исследования влияния теплоаккумулирующей стены с водяным теплообменником на охлаждение зданий.
В первой части статьи дано описание математической модели здания. Моделирование осуществлялось с помощью программы TRNSYS, позволяющей производить расчет почасовой нагрузки охлаждения теплоаккумулирующих стен с водяным теплообменником с целью последующего сравнения с нагрузкой охлаждения эталонной комнаты. Приведены схема моделирования здания, модель тепловой сети, методика расчета общего термического сопротивления термоактивного слоя стены.
Ключевые слова: тепловая энергия, пассивное охлаждение, теплоаккумулирующая стена, водяной теплообменник, программа TRNSYS.

The paper presents the results of mathematical modeling and experimental research of the effect of a heataccumulating wall with a water heat exchanger on building cooling.
The first part describes the mathematical model of the building. The modeling was carried out using the TRNSYS program that allowed computing an hourly load of cooling the heataccumulating walls with a water heat exchanger for the purpose of subsequent comparison with the cooling load of a sample room. The building modeling scheme, the heat network model, and the method of calculating the total thermal resistance of the thermosetting wall layer are given as well.
Keywords: heat energy, passive cooling, heataccumulating wall, water heat exchanger, TRNSYS program.
