2. Project idea
Finnish Forest Research Institute contacted Mikkeli University of Applied Sciences, Building Services Programme, in June 2006
The Institute studies the growing of forest and trees and the suitability of foreign trees to Finnish climate
There is a regional research laboratory in Punkaharju in Eastern Finland
There they have a research chamber for cones
The reason for the phone call: to develop the thermal conditions of the research chamber for cones
 Visit to Punkaharju during the summer 2006

5. Existing research chamber for the cones
Dimensions: width about 3 m, depth about 3,8 m, height about 3 m
Metal door, width about 0,9 m
Inner walls of the chamber are covered with building board
One single air conditioning unit serves the research chamber
No humidity control
There are several shelves in the chamber
Cones are put into boxes on the shelves

10. This is what they would like to have:
About 10 different research chambers for the cones (volume 1-2 m3)
Each chamber could be controlled individually, as well as monitored for:
Temperature
Humidity
THE NEW SYSTEM SHOULD OPERATE WELL AND BE CHEAP TO INSTALL!

11. The future use of the research chambers
Year round use
For the studies of small amounts of cones
The cones of different types of trees could be studied in different thermal conditions
At the same time, they could run several different tests in different research chambers
Marianna Luoma

12. Requirements for the new research chamber
About 10 different research chambers
Temperature range +20 … +60 oC
Temperature rise +2 … 5 oC per hour, when the temperature of +60 oC should be reached
Relative humidity %RH …. 60/70 %RH.
When the desired temperature is reached, it should keep the desired relative humidity, for example +50 oC ja 70 %RH for three hours
Each chamber has to be individually programmed
The information of the thermal conditions of each chamber should be monitored and controlled automatically by a computer

13. Heat source
In the neighbourhood, there is a small power plant using woodchips, and it produces hot water
Hot water could be used as a heat source for the air conditioning unit
The water is temperature oC

15. The Forest Research Institute asked us to propose for a preliminary study
Contents of the proposal:
Prelimary study about HVAC and building automation solutions that would be capable of meeting the requirements set for the test chambers
Preliminary drawings about different solutions
Preliminary estimation of costs
Marianna Luoma

16. Starting to prepare the proposal
What kind of background information would we need to get from the Forest Research Institute?
Principle solutions for an HVAC system, in which the thermal conditions (temperature and humidity) could be controlled individually for each research chamber
What kind of other issues should we take into account?
What kind of expertise is needed in the project group?
The preliminary study would consist of several phases. What would they be?
Marianna Luoma

17. Doing this exercise
The purpose of this exercise is to get an idea of the principles of the solutions; detailed drawings and dimensions are not needed
You will work in groups of 3 persons
You should explain your solutions in written form
The group has to prepare a written answer and present it with the help of a slide show
You could draw some sketches of the principal solutions
Put the names of the group members to your answer
The oral presentations are held on Tuesday the 27th of September 2011
