Mathematical modeling of the building thermal state taking into account the heat and energy impact of the environment

[摘要] There are some difficulties in analysing the actual thermal state of a building under changing conditions of the environment, particularly solar insolation. The methodological approach to overcoming these difficulties and the corresponding mathematical models of the thermal state of a building are proposed. The base of the models is a power circuit in which there are described all components of heat losses and heat revenues. Controlled and uncontrolled heating systems are considered by representing heating devices as a source of effort or as a source of flow. The proposed models as a result of the analysis of the thermal state allow obtaining energy indicators of the building and an objective picture of the thermal comfort in the rooms simultaneously.
