Review exercise4

[lucasverleyen]

@jelgerjansen @JavierArroyoBastida @Mathadon I finished the review of exercise 4.

• Minor details
• New plots
• Adapted explanation for reference results in chapter 1 as the plots changed
• !! I calculated the COPs again.
• --- Chapter 1, Reference results: COP = 2.9 (in stead of 2.7 before)
• --- Chapter 2, Reference results: COP doesn't change significantly anymore. Only from 2.9 (without control, cf. chapter 1) to 3.1 (with control, cf. chapter 2).
• Qcon,without = 33.51 kWh, Pwithout =11.56 kWh
• Qcon,with = 29.69 kWh, Pwith = 9.64 kWh
• !! I added a schematic of the model of the last chapter. I remember from last year that is was difficult to do everything in time and that it is quite challenging to develop the last model. I think it will be beneficial that the participants have an overview of the final model to know where to go to.

I will create an issue for next years to adress the 'problem' of the overdimensioned heat pump, but merge the changes for this year.
