Study of house heating model driven by thermostat and calculation of temperatures distribution during specific time using Matlab\simulink and SolidWorks 2017

Abstract

In this paper, the distribution of temperatures, heat gain, and heat loss from/to building as a function of time, were studied. Where the hot air passing through a heating source driven by a thermostat to keep the room temperature at a constant value . When the temperature of the outside changes sinusoidal between the values ,  over a period of 48 hours.

We used the Matlab \ Simulink simulation software to study the one-dimensional mathematical model of heat transfer, and SolidWorks program to study the thermal behavior of the studied model in three dimensions and calculate the distribution of fluid temperature, velocity, and density.

The temperature of the air inside the room will fluctuate by  from the set temperature , as the temperature of the outside increase, as the frequency of the signals coming from the thermostat decrease. the amount of gained heat reached  over a period of 48 hours, while the maximum velocity of air inside the building was about 1.76 m / s.
