Suddenly he appeared again today, anxious to get on and complete the dissertation. It is obvious from the conversation that he has been reading this blog quite thoroughly, so I was willing to discuss it further and with some urgency. Let's hope it's a good one - the hand in is near the end of May.
The earlier dissertation, by Robert the B.A student, has already been printed and handed in, so I look forward to seeing a copy of that.
The PhD student, Blaise sent me three revised drawings of the circuit (in different operating modes) that he intends to use in our co-authored write up on the project. I made some small corrections and returned them for his approval. They show:
- the heatpump working without the sunboxes,
- the heatpump working as a hybrid system with both ground and sunboxes, and
- the sunboxes working when the heatpump is 'sleeping'.
