The performance of the developed treatment device and control program was evaluated. The building was covered with air-tight and thermal isolation walls and a roof consisting of double-layered polystyrene boards sandwiched by 12 ㎜ thick plywood and PVC film. Four treatment units consisting of a fan, a heater, and a steam sprayer were installed in the covering house, from which the humidity-controlled warm air was generated and circulated. Another duct conveying the cooling and dehumidifying air was attached in front of the fun. The volume of the treatment space was about 700 ㎥ . According to the measurement of the moisture content of the wooden building, it was clarified that the target moisture content to be kept constant in the treatment should be 17%. In order to keep the equilibrium moisture content of 17%, the temperature and relative humidity of 27℃ and 83% at the start of the treatment was increased gradually up to 60℃ and 89% in the period of four days, then kept constant at these values for about two days, and finally decreased down to the initial values for four days. The temperature and relative humidity in the insulation house were correctly controlled, so that the difference between the scheduled temperature and relative humidity and the actual measured ones was small. The consumed electric power and the noise level in and outside of the house were also measured and found to be under acceptable limit values.}, pages = {13--33}, title = {〔報文〕 湿度制御した温風処理による木造建造物加害甲虫類の殺虫(1) ―温湿度制御性能の評価―}, year = {2023} }
