摘要
Taking the nearly zero energy residence and conventional residence in hot summer and cold winter zone as research objects, the dehumidification capacity in summer and dehumidification period was calculated. The characteristics of angle scale and indoor high humidity of two kinds of buildings were studied comparatively. The results show that: the variation of dehumidification capacity of nearly zero energy residence and conventional residence are mainly determined by the amount of fresh air and infiltration rate. Air exchange rate during uninhabited period have little influence on the dehumidification capacity. Without considering the sensible heat load and moisture load of fresh air, the angle scale of nearly zero energy residence in summer and dehumidification period is reduced to that of conventional residence 45.3% and 38.5% respectively. High humidity period of nearly zero energy residence in summer and dehumidification period is longer than that of conventional residence when indoor temperature is selected as the control parameter. Limiting the air exchange rate during uninhabited period of nearly zero energy residence in summer and ventilating properly in dehumidification period contributes to decrease the indoor high humidity time period. © 2020, Editorial Department of Journal of Tongji University.
