Résumé

In the paper a new concept of phase change materials (PCMs) integration with building envelope is presented. These materials due to high thermal capacity when integrated with the building structure lead to the stabilization of interior temperature. The idea is to build a ceiling in the form of thick board with parallel internal channels for air flow. Such a ceiling would be a part of a building ventilation system - air taken from the environment flows through the channels and exchange heat with a the construction material. Due to increased thermal capacity, resulting from the content of PCM, the panel works as a regenerative heat exchanger. When a melting point of PCM is properly chosen it is possible that air temperature flowing into the building reach a level corresponding to thermal comfort conditions, regardless the temperature at the intake. Warm air (during a day) release the heat basically to PCM causing its melting. During night time cool ambient air is heated up while it takes back heat accumulated in PCM. An experimental set-up based on the above concept was developed. A series of tests in different conditions (inlet air temperature, air flow rate) were performed. Information on thermal performance of the ceiling panel as well as detailed data on heat transfer process were obtained and discussed in the paper.
