Cooling potential of heating-cooling wall panels

This paper presents the technological part of activities executed in the framework of MUSEUMS Project Slovene Ethnographic Museum, Ljubljana, Slovenia. To assure thermal stability of exhibition rooms and to achieve optimal relation between air temperature and walls surface temperature a combined thermal insulation and heating-cooling wall system was designed as a low temperature large surface heating and cooling vertical system. The thermal comfort is improved because of surface temperature air temperature relation lateral radiation effect. Optimal relation between air temperature and surface temperature is achieved with the use of heating/cooling wall panels. System is connected to district heating system for heating purposes in winter and to cooling plant for cooling purposes in summer. Wall cooling system starts to work if outside conditions do not enable cooling of the building with ventilation.
