 note = {One problem in the museum environment is air pollutants in airtight display cases, some of which cause adverse effects on artifacts inside.Their gases,especially acetic acid gas, are mainly emitted from interior materials used in display cases. There are two systems for reducing the level of pollutants inside the enclosure.One is an active adsorption filter fan system and the other is a ventilation fan system that takes the clean air from the exhibition room.The present paper reports on the test using these systems to control acetic acid gas pollutants in a display case.
 Several measurements were conducted to see air distribution, air exchange rate and acetic acid gas concentration in a display case. The display case used in the experiments was made for environment test. Performance of active adsorption air filter within enclosures and ventilation effect by the fan were also measured.
 As a result it was found that acetic acid gas concentration in the display case decreased to 30% by using an adsorption filter fan system and it became of equal level to that in an exhibition room by using a ventilation system. Effects of control of pollutants
by each system were evaluated by using ventilation volume with clean air (i.e. equivalent ventilation volume). Changes of gas concentration in the display case were estimated through prediction formula using factors of equivalent ventilation amount and operating period of the fan. From the results it was estimated that good air environment in the display case was maintained by operating an adsorption filter fan system for about two hours a day.},
