EVALUATION OF THE MOISTURE APPEARENCE IN THE ICE RINK FACILITIES BASED ON OBSERVATION STUDIES AND PERFORMED SIMULATIONS IN HYGROTHERMAL SOFTWARE

Sammanfattning: In the paper, there are presented issues related to the ice rink venues. These widely known objects,all around the world,are one of the most complex types of the public buildings. It is caused mainly by the thermal conditions, which prevails in such objects but also energy demand needed for operational processes. Range of indoor temperatures may vary from -5oC in place of ice pad and close to it, up to +20oC in dressing rooms, offices or tribunes for the spectators. Like any other buildings, the same ice rink venues should meet the conditions and provide proper indoor environmental quality (IEQ) for every user of the object. It is mainly performed by the appliance of the newest technology, which is taking care and control aspects like: temperature, relative humidity, energy usage, lighting etc. In this document, there are presented 5 ice rink facilities,which were taken into account, in order to check if there are providing comfortable and proper conditions indoors. All the investigated halls were in the City of Stockholm. In order to obtain require data, some professional tools were used including infrared camera and moisture meter. The registered data was including the average temperature of the indoor air and level of relative humidity. Based on this data, the dew point temperature has been calculated. Another aspect of the work was carrying out simulations of the typical ice rink wall construction and finding the best possible placement for the vapour barrier. In these case, the simulation had been performed in the different cities located in Sweden. Function of this layer is mainly to inhibit the migration of the water vapor and to protect the thermal insulation layer from dampness. However, installed in wrong place in the wall composition may give rise to serious problems related to moisture and humidity. By using WUFI software, it was possible to present hygrothermal conditions like: relative humidity, dew point temperature and water content of the individual component of designed wallin relation to different placement of damp proofing material.
