Sensitive Analysis for Excessive Dryness During Heating and Prediction of Hygrothermal Environment

In order to improve the indoor air quality (IAQ) problem caused by microbes such as mold and mites, and the decrepitude of buildings, desiccant air-conditioning systems have been adopted in buildings. However, conventional desiccant air-conditioning systems are mainly adopted for large-scale buildings, such as offices and hotels. They have rotors for desiccant and sensible heat exchange and therefore require a rather large machine room for air-conditioning. However, detached houses rarely have enough spaces for air-conditioning systems. In addition, little research in passive methods utilizing a desiccant or natural ventilation has been reported.Sometimes passive methods are affected by outdoor conditions and are not feasible for stable correspondence to indoor loads.In this paper, a batch-type desiccant air-conditioning system placed in the floor cavity was proposed which is able to operate perennially in both cooling-dehumidification and heating-humidification modes with ventilation. In order to estimate the heating-humidification performance of the proposed system, a small-scale model experiment was conducted and a numerical analysis model was developed. By using the developed numerical analysis model, a sensitivity analysis was conducted with performance-parameters such as air flow rate, quantity of desiccant, mass flow rate of hot and cold water, temperature of hot and cold water and transposed interval.

Many residences with high thermal performance are equipped with sensible-heat type heating equipment that generates no moisture. To preserve air quality, therefore, such residences require ventilation at scheduled intervals, resulting in the problem of dry room interiors. Humidifiers used for simple hygrothermal regulation require approximately 150 W of electricity, encouraging additional energy consumption. In this study, we simulated a hygrothermal distribution that does not consume energy, using moisture generated by drying wet laundry in a room. There was no damage due to condensation formed on windows or other moisture condensation in the room next to the heated room.
