Thank you for your reply but here problem lies in calculating qg. We can get Tin by integration but for that we need qg at input as is shown in my model (attached). So now my problem is how can I get qg?
Thank you for your reply sir. Sure I can share pdf file of that paper in which this model is discussed. Actually Tin is input of model but I have to calculate it through this equation otherwise there is no mean to know this.
One thing that is given in paper (attached) is a operating set point for temperature which is given as 20 for day and 16 for night but I do not know whether its initial condition for temperature or not. Can anyone please guide me that what kind of equation is it and how can I solve it with these...
