Simulation Of Thermal Model of a House Projects using MATLAB

Introduction—

MATLABSolutions demonstrate In this task we are going to design the thermal model of a house. This system models the outdoor environment, the thermal characteristics of the house, and the house heating system.

The sldemo_househeat_data.m file initializes data in the model workspace. To make changes, you can edit the model workspace directly or edit the file and re-load the model workspace. To view the model workspace, from the Simulink Editor Modeling tab, click Model Explorer.

Initialize Model

This model calculates heating costs for a generic house. Opening the model loads the information about the house from the sldemo_househeat_data.m file. The file does the following:

• Defines the house geometry (size, number of windows)
• Specifies the thermal properties of house materials
• Calculates the thermal resistance of the house
• Provides the heater characteristics (temperature of the hot air, flow-rate)
• Defines the cost of electricity (0.09$/kWhr)
• Specifies the initial room temperature (20 ºC = 68 ºF)
• Note: Time is given in units of hours. Certain quantities, like air flow-rate, are expressed per hour (not per second).
