Study on the rule of indoor air temperature falling in damage accident of heat- supply network
The indoor environment becomes bad rapidly when heat-supply network is in damage accident. For human comfort and studying on the rule of indoor air temperature transformation, ascertaining the permitted lowest temperature is the vital problem, which is related to residential environment. The unsteady-state heat transfer of envelopes is described by reaction coefficient method and lumped-heating-capacity method synthetically, then the construction mathematical model in dynamic heat transfer course is constructed. The dynamic course of indoor air temperature in different indoor and outdoor disturbances is studied, it can depict the rule of indoor air temperature falling and the solar radiations influence. Indoor air temperature of a Changchuns building is tested while no heating. The experimental results are compared to simulated data, it shows the mathematical simulation model is feasible.
