ACTUAL MEASUREMENT OF THE HUMIDIFICATION EFFECT OF CENTRAL AIR-CONDITIONING SYSTEM EQUIPPED WITH A DESICCANT DEVICE AND CONSTRUCTION OF A CALCULATION MODEL

Central air-conditioning systems are expected to provide high-quality thermal environments that contribute to improving the health and comfort of residents. However, in winter, a high room temperature is maintained, which decreases the indoor relative humidity. To combat this dryness, water-supply humidifiers may be used, but this carries the risk of microbial growth. Another method is a desiccant device. Therefore, in this study, we performed actual measurements of a residential central air-conditioning system equipped with a desiccant device. In addition, we constructed a numerical simulation model capable of reproducing actual measurements in order to quantify the humidification effect.
