Optimization of microclimate in an orthodox church by numerical simulation of air flow

Despite the strict rules of design and construction of religious buildings, often in modern churches there are some problems with heating and ventilation. In a complex building, it is necessary to organize proper air exchange and ensure proper heating of the air throughout the space, calculate the geometry of natural flows and supply jets, ensure the removal of contaminated air bypassing the areas of congestion, and protect wall paintings and art objects from settling of soot and dirt particles. The problems described above are relevant for the Holy Ascension Cathedral in Magnitogorsk. Despite the relatively short period of operation of the building, the appearance of its interior decoration is significantly different from the original form: the inner surfaces of the temple walls are smoked so, that in the upper half frescoes and paintings are no longer distinguishable. Urgent measures should be taken to save it. It is proposed to solve the problems by using the electronic numerical model of heat and air flow. The study allowed to make a number of recommendations aimed at improving the ventilation of the temple.
