Solutions For The Future (3)

Just to add some insights on the DH topic without being misunderstood of making a scientific article. About the high temperature system (110/90 or 90/70) and the use of a low temperature scheme (50/30).
In the current operation of high temperature DH systems the return line (70-90C) can be used in heating houses at a relatively lower temperature scheme. Of course these houses heating system needs to be designed on that basis. In addition, another possibility of combining the system for individual group of houses with a ground heat pump may be thought of to cover the peaks for the domestic hot water. The integration of that is expected to be energy efficient. In Finland cooling is not needed for a common residential building (no glass facades) but with the climate change they might need to simply pass the fresh air over the heat pump evaporator and deliver the fresh air mechanically. The cost is not big for having extra openings, a suitable duct work plus a fan. The extracted energy in that case won't be of a big concern but more the aim is to utilize the existing machinery. The delivered heating energy is the crucial task and the covered/demand needs to be 100% guaranteed.

Next time let's talk more about ground source heat pump :)

TOOMAS TIIKMA

Toomas Tiikma was a special man full of great manners. Yesterday, I knew that he passed away more than 3 years ago. July 2004 I sent him last mail asking how is it going? he answered wishing me the best in my new job… I thought he’s busy and I got busy myself after that, but it was always in my mind that he’s there and I’ll visit him someday(maybe I needed to apply for visa).

Yesterday I don’t know how I ended up looking TTU, (thermal engineering dept.) webpage… I didn’t find Tiikma’s name in the personnel list and by searching on net I found that he died 12.09.2004.

Professor Tiikma was a different kind of people... he was a genius scientist but very modest. He was a very respectable man and full of kindness. What I can say... I really lost my Estonian father. I’ll pray for him and I’ll miss him.

Do you feel you are smarter than your friends?

My answer to the above question was NO.
Because I have no friends :)
But in general I really don't believe that I'm smarter than anybody because this cannot be generalized. I might be smarter in a certain thing and they might be in others.

Back to my friends, it's really bad thing when you realize that you have no friends maybe I have couple of them but they are quite far and busy in life. Good friends are important but you never find them that easy... You might get shocked when you find the people you thought they are friends or colleagues have been simply doing their job nothing more!

The person is called a good friend if and only if he always goes in parallel to you and you never intersect with him. You might get near just for critical points but always come back to the previous offset line.

What I want to say is that, in lifetime we may meet the good friends but most probably we may not so try to build your resistance to the so-called friends because their troubles are much more than their benefits.
