Bachelor\'s Thesis Presentation

  1. 2. Maintaining thermal conditions in exhibition of Russian Museum and in Archive of Mikkeli Student: Natalia Ladygina Supervisors: Marianna Luoma, Heikki Salomaa 14.12.2009
  2. 3. Background <ul><li>Material of exhibit determines storing conditions </li></ul><ul><li>Conditions in museums and archives vary </li></ul><ul><li>Requirements are defined by the Standards </li></ul><ul><ul><li>Air temperature </li></ul></ul><ul><ul><li>Relative humidity </li></ul></ul><ul><ul><li>Air velocity </li></ul></ul><ul><ul><li>Air change rate (in some cases) </li></ul></ul><ul><li>Climate control by air conditioning system and automation system </li></ul>
  3. 4. Aims <ul><li>Studying air conditioning systems in Russian Museum and Archive of Mikkeli </li></ul><ul><li>Finding out whether they provide required conditions or not </li></ul><ul><li>If not, giving the reasons why and recommendations about improving the indoor climate </li></ul>
  4. 5. Methods and materials <ul><li>Literature review </li></ul><ul><ul><li>Influence of conditions on the materials </li></ul></ul><ul><ul><li>Standards and requirements </li></ul></ul><ul><ul><li>Air conditioning systems and equipment </li></ul></ul><ul><li>Russian Museum </li></ul><ul><ul><li>Exhibition of wooden furniture and fabric </li></ul></ul><ul><ul><li>Interview with the head of Climatology Department </li></ul></ul><ul><ul><li>Drawings of AC-systems </li></ul></ul><ul><ul><li>Diagrams of temperature and relative humidity </li></ul></ul><ul><li>Archive of Mikkeli </li></ul><ul><ul><li>Archives of books and microfilms </li></ul></ul><ul><ul><li>Drawings of AC-systems </li></ul></ul><ul><ul><li>Measurements of temperature and relative humidity </li></ul></ul>
  5. 6. Results 45 35,5 ± 0,3 38,2 ± 0,5 18 18 ± 0,1 17,6 ± 0,4 Modern archive of books #2, Archive of Mikkeli (December) 45 43 ± 0,6 45 ± 0,6 18 16 ± 0,1 15,7 ± 0,1 Archive of books #1, Archive of Mikkeli (December) 30...40 31 ± 6 16...18 or lower 14 ± 1 Archive of microfilms, Archive of Mikkeli (December) 50…55 47 ± 3 18…22 24,5 ± 1 Exhibit of wooden furniture and fabric, Russian Museum (June) 50…55 48 ± 3 18…22 23,5 ± 1 Exhibit of wooden furniture and fabric, Russian Museum (May) Required RH, % Average RH, % Required T, ºC Average T, ºC Place (month of measurement)
  6. 7. Analysis of the results <ul><li>Reasons why the required conditions were not provided: </li></ul><ul><li>Exhibit of wooden furniture and fabric, Russian Museum </li></ul><ul><ul><li>Heat gains from solar radiation </li></ul></ul><ul><ul><li>Heat gains from visitors </li></ul></ul><ul><ul><li>Low capacity of humidifiers </li></ul></ul><ul><li>Archive of books #1, Archive of Mikkeli </li></ul><ul><ul><li>Inability of AC-system to maintain constant indoor conditions </li></ul></ul><ul><ul><li>Location inside the rock </li></ul></ul><ul><li>Modern archive of books #2, Archive of Mikkeli </li></ul><ul><ul><li>Drying effect of the radiators </li></ul></ul>
  7. 8. Conclusions and recommendations <ul><li>To improve the indoor conditions I would recommend: </li></ul><ul><li>For exhibit of wooden furniture and fabric, Russian Museum </li></ul><ul><ul><li>To apply Venetian blinds </li></ul></ul><ul><ul><li>To buy more movable humidifiers or replace them with more efficient ones </li></ul></ul><ul><li>For archive of books #1, Archive of Mikkeli </li></ul><ul><ul><li>To apply movable heat emitters with the low output </li></ul></ul><ul><li>For modern archive of books #2, Archive of Mikkeli </li></ul><ul><ul><li>To reduce the output of the radiators and increase the heating output of the AC-system </li></ul></ul><ul><ul><li>To add a humidifier to AC-system </li></ul></ul>
  8. 9. Thank you for your attention!
