Indoor aerosol transport and deposition for various types of space heating

Original language description

Computational modelling of aerosol transport under various heating systems in a room was conducted with the goal to understand and evaluate a regional deposition and to assess an optimum position for air cleaning device. Three heating systems are taken into account, namely radiators, floor heating and ceiling radiation panels in ventilated room. Thermal diversity is simulated by varying the ventilation air and outdoor temperatures. Aerosol entering the room has a discrete size spectrum 1, 2.5 and 10 umof particle diameters. The room is divided into several regions where the deposition is evaluated for individual aerosol sizes and outdoor and incoming air temperatures. Also the air velocity and temperature fields in the room are drawn to support the analysis of deposition patterns. The void fraction of the aerosol phase also shows the space distribution inside the room and provides us with an overall view of the aerosol transport.

Transport a depozícia aerosólu pri roznych typoch vykurovacích systémov

Czech description

Bol vytvorený počítačový model miestosti, na ktorom bol simulovaný transport a depozícia aerosólu. Prípady sa líšili použitým vykurovacím systémom a parametrami vetracieho vzduchu. Bolo skúmané správanie sa častíc aerodynamických priemerov 1, 2.5 and 10um pri použitom podlahovom, stropnom a radiátorovom vykurovaní. Analýza bola vykonaná na základe štúdie teplotných a rýchlostných polí vzduchu v miestnosti v súlade s poliami koncentrácií častíc. Výsledky transportu častíc boli zobrazené v príslušných obrázkoch miestnotsti, zatiaľ čo hodnoty depozície boli vynesené do grafov pre príslušné povrchy miestnosti.
