Abstract
In winter, low humidity often occurs in offices even in operation of humidification. It is necessary to reveal the humidification rate of each case and to consider ways to deal with low humidity. In this study, we estimated the humidification rate of air conditioners at the office room based on the air moisture balance equation with acquired or estimated values (indoor/outdoor temperature and humidity time series data for the office, ventilation rate, moisture generation rate from human body, etc.). Then, we confirmed the validity of estimation using measured absolute humidity of the air outlet of the outdoor air conditioner. Finally, we analyzed parameter sensitivity for estimated humidification rate. The result showed that the number of occupants and ventilation rate had a relatively larger effect on the estimated results, while the quantity of moisture absorption/desorption from the porous materials affects at the starting of humidification and had a smaller effect on the trends of the whole day.
