The Calculation of Indoor Air Forecast Temperature of a Space with the Replaceable Thermotechnical Characteristics of the Enclosure Structures While in Operation

In this article there are given the calculations of indoor air forecast temperature of a space, having the outer enclosure structures with the replaceable thermotechnical characteristics of structural layers while in operation. The indoor temperature forecasting is an interesting and actual task, which makes it possible to solve problems related to the process of ensuring the parameters of the indoor microclimate, as well as social. The solving of this task depends on many factors influencing the maintenance of a stable indoor air temperature. The one-dimensional thermal field in a flat wall with a fixed heat transfer process between warm and cold air, which have constant temperatures and processes of internal destruction of building materials is considered as a basis for solving this task. The solution of the problem involves determining the coefficient of heat transfer, or the thermal resistance of the outer wall under conditions of their variation in operation and the final determination of the indoor air forecasting temperature. The derivation of an equation of determination of the indoor air forecasting temperature is based on the assumption that the heating losses of the room are equal to heat inputs of the heating appliances/unit heaters of the heating system. As a result, the equation of determination of the indoor air forecasting temperature subject to alterations of thermotechnical characteristics of structural layers and the enclosing parts is obtained.
