Features of Functioning of the Combined Air Heating Systems and Ventilation of a Three-story Museum

Abstract

The analysis of the air-thermal regime of a three-story experimental residential museum building with a basement floor is presented. The equations of material and energy balances of the investigated building were compiled, allowing to determine the required air temperature at the outlet of the stream from the air-heating chamber. A method for determining the maximum performance of an air heater of a combined air heating and ventilation system at given temperatures of outside air and fresh air at the outlet of the jet from the air distributor is presented. The dependence of the thermal performance of the air heater on the change in the outside air temperature is established, with the same parameters of supply air at the outlet of the air distributors. A method for determining the parameters of supply air at the outlet of the jet from the air distributor, which allows to ensure the necessary parameters of the air inside the heated premises, is proposed. A survey of the temperature and humidity of the microclimate in the premises of the building, allows us to estimate the sanitary and hygienic conditions. A method for the simultaneous application of the processes of humidification and heating of the supply air in the combined air heating and ventilation system providing the specified microclimate parameters in the premises of the building under study is proposed.
