冬季空调不加湿对室内参数的影响

基于质量守恒方程导出了冬季空调系统不加湿时房间内的含湿量计算式,综合考虑影响室内含湿量的主要因素,得出冬季空调可以不加湿时应满足的条件,考察了中国典型气候区代表性空调房间冬季空调不加湿时室内相对湿度能否满足设计要求。研究表明:中国各地区的商场,夏热冬冷地区的餐厅及三星级及以下酒店多功能厅,夏热冬暖地区的影剧院、办公室、酒店客房及多功能厅、餐厅,温和地区的办公室、三星级及以下酒店客房、酒店多功能厅及餐厅空调系统不加湿即可达到设计湿度要求;严寒地区及寒冷地区的影剧院、办公室、酒店客房、酒店多功能厅及餐厅,夏热冬冷地区的影剧院、办公室、酒店客房、四星级及以上酒店多功能厅以及温和地区的影剧院、四星级及以上酒店客房等房间的空调系统必须加湿才能达到设计要求。

Humidity analysis of air-conditioned rooms without humidification in winter

Based on the mass conservation equation, the calculation formula of the moisture content in the air-conditioned room without humidification in winter are deduced. Synthetically considering major influencing factors of the indoor moisture content, the criterion used to estimate the relative humidity of air-conditioned rooms without humidification in winter are established. Furthermore, the relative humidity in typical air-conditioned rooms without humidification in typical climate regions in winter is checked against the criterion. The main conclusions are as follows:the relative humidity of air-conditioned supermarket all around our country, restaurants and the multi-purpose halls of 3-star and below 3-star hotel in the "hot summer and cold winter" climatic region, movie theaters,office, the bedrooms and multi-purpose halls of hotel, restaurants in the "hot summer and warm winter" climatic region, and office, the bedrooms of 3-star and below 3 star hotel, the multi-purpose halls of hotel and restaurants in the "mild" climatic region can meet the required value without humidification. But, the relative humidity of air-conditioned movie theaters, office, the bedrooms and multi-purpose halls of hotel and the restaurants in the "cold" and "severe cold" climatic region, movie theaters, office, the bedrooms of hotels, and the multi-purpose halls of 4 star and over 4 star hotels in the "hot in summer and cold in winter", and movie theaters, the bedrooms and multi-purpose halls of 4-star and over 4-star of hotels in the "mild" climatic region can not meet the required value without humidification.
