00:01 Hello students in this question.

00:03 We have a house.

00:05 This is a system.

00:07 So dynamic system of house, so we need to arrange this system without a heater the average temperature of the house is going to be varied over a 24 hours time period so what would be the inputs outputs and state variables for this dynamic model? so we need to accommodate multiple rooms just like this and then we have to connect them together and these also has to be accounted for right if this is the dynamic system so and also how does the installation of thermo statistically? statically controlled heat exchanger or heater change our model so as the heating engineer you need to develop a simple dynamic model so inputs are external temperatures temperature then solar radiation coming into the system and the heating system inside heating system as a whole then output will be the internal temperature that is the primary interest here now this is the input this is the output now the variables what are the variables so variables are internal heat variables heat gains and thermal mass so we can expand this model to several rooms and we need to account for all the heat exchange between these rooms the insulation and the conductivity of the doors handles everything has to be accounted for so this when we set up with the installation we we will have the setup explained dynamically now with a heat installation with the installation of a heat controller or thermo statical controller with heater this model will have another set of additional elements of variables which is heater grid or control and the system? heating system and air circulation so this will be airflow system heating system and the heating grid that we have the control grid that we have so this is the model now this is theoretical abstract of a model now coming to back to the heat equation right so we have the grid which is dissipating heat so solar energy is coming in right through the windows it is coming in and then it is being dissipated through internal temperature changes towards the area dynamical area under the roof so it's exchanged from one place to another so there is a temperature t out and this is t in at different areas so we can say that the heat the airflow and ventilation and all these things are cons for a q...
