摘要:

基于质量守恒方程,导出了冬季空调不加湿时室内空气含湿量的计算公式,综合考虑影响含湿量的主要因素,得出冬季空调不加湿时应满足的条件,并考察了昆明地区具有代表性空调房间冬季空调不加湿时室内相对湿度是否满足设计要求。结果表明:在昆明地区冬季空调不加湿时,商场的相对湿度高于设计要求,需要除湿;酒店多功能厅及餐厅空调系统不加湿亦可达到设计要求;而影剧院、酒店客房的相对湿度低于设计要求,空调系统必须加湿。

Abstract:

Based on the mass conservation equation, deduces a calculation formula of the indoor air humidity ratio when air conditioning system without humidification operating in winter. Generally considers the major influencing factors of the humidity ratio, obtains the conditions used to estimate the relative humidity. Furthermore, investigates whether the indoor relative humidity meets the design requirements in typical air conditioning rooms without humidification in winter of Kunming region. The results show that in the air conditioning rooms without humidification in winter of Kunming region, the relative humidity of the mall exceeds the required value and needs to dehumidify, and the relative humidity of multi-purpose halls and restaurants in the hotel can meet the required value. But the relative humidity of movie theaters and hotel guestrooms can not meet the required value without humidification.
