Heating of residential buildings in hot summer and cold winter zone

Stresses the necessity of heating in residential buildings in this zone, and presents main heating modes currently adopted. Records and analyses the vertical distribution of temperature and relative humidity of indoor air after the split air conditioner operating for two to three hours in a residence unit in Chengdu. The result indicates that the stratification of the temperature and relative humidity is obvious, the heating effect and thermal comfort are not desirable in a short time(two to three hours). Discusses the practicable scheme of heating in this zone.
