The control of indoor thermal conditions needs dynamic modeling of indoor air temperature in buildings. The indoor air temperature is influenced by four factors: outdoor weather conditions occupants; plug-in electric load used in air-conditioning zones; and cooling and heating energy consumed by air-conditioning system. Weather conditions, occupants and plug-in electric load are considered as random...
Uniformity of temperature is important to comfortable indoor environment in building automation system (BAS). Usually, only a single temperature sensor is placed in the conditioned space for controlling an air handling unit (AHU) operation by using a direct digital controller (DDC) to maintain thermal comfort conditions. In order to improve an efficiency of heating, ventilating, and air conditioning...
When there is the desire to achieve optimal temperature control for a building or its energetic performance description, one of the steps that should be followed is to identify experimentally the dynamic model for heat transfer in that building. In these models there are used heat equations in time domain, but as these systems have multiple inputs and outputs, these equations can be represented in...
The main provisions of the techniques of imitation modeling by the numerical methods of measuring processes of the multifunctional force sensor are analyzed. Its physical model is described. One of the options for elastic element design is provided.
This paper focuses on the system identification of the thermal dynamics of a domestic dwelling and the aim of the modelling process is to design an efficient control scheme that minimises energy usage and, consequently, fuel bills. Existing software packages for thermal modelling of structures are based on physical models or finite element analysis and use real data for comparative purposes only....
