Design of displacement ventilation system in museum premises

Abstract

In museum premises located in architectural monuments, an important issue is ensuring the regulatory parameters of the air environment. And the method of organizing air exchange in exhibition and exposition halls. In such buildings, it is impossible to conduct air ducts, therefore existing ducts from fireplaces and natural exhaust ducts are used. The article discussed the National Center of Folk Culture "Ivan Honchar Museum". In a series of field studies, the average air temperature in the room was within twz = 20 °С, and the relative humidity was φwz = 55-60 % in the exhibition halls. two options for organizing air exchange. A three-dimensional model was created for the study of air exchange and air flow between halls, and air movement was simulated in two variants for rooms No. 40, 47 and 48. Taking into account the field studies and mathematical modeling of air exchange organization options, a project for the modernization of ventilation and air conditioning systems was proposed.
