The humidification capacity and thermal comfort of the heating room in winter

Abstract

This paper briefly describes the lower relative humidity of the heating room in winter in northern China than in southern China and discusses the relationship between the indoor relative humidity and the thermal comfort. Meanwhile, the required humidification of indoor air is calculated in this paper when it reaches to the indoor comfort zone, and the curve of the relative humidity is drawn with humidification changing. This paper also introduces the common household humidifiers and selection principles and gives the way how to control the indoor relative humidity. Furthermore, it shows how to calculate the humidification of indoor air for the comfortable design condition with heating technology. Consequently, several conclusions are reached. © Springer-Verlag Berlin Heidelberg 2014.
