住宅房間空调器運行冷負荷實測:傢具等釋放之潛熱与控制模式之关糸

於晚上約9時啟動睡房空調器,並量度了房间温度丶相对濕度変化丶压縮机啟丶佇時间及送风温度.以此計算了顯熱及潛熱冷負荷之変化.發現压縮机運行時傢具降温時所散發之潛熱為压縮机佇運時丶傢具升温時之多倍丶约8至9倍.分析及計算推論:若控制為modulating模式,傢具散濕量大幅下降約28%,5小特總耗冷量下降約8.2%.

Room air-conditioner was started at approx.9 p.m.in the evening.Then,room temperature and relative humidity variations,supply air temperatures,and the time of com-pressor start and stop were recorded.Variation of the sensible and latent cooling loads were then calculated.It was found that latent load from fur-nishing is much higher(approx.8 to 9 times)during compressor ON periods than that during OFF periods.Further calculation analysis was done which suggests that modulating control would give 28%less latent load from furnishing,and total 8.2%less in total cooling consumption for 5 hrs operation in the隌evening.
