对马来西亚国家博物馆的热环境和居住者的舒适度进行了实地研究。对博物馆内居住者的热感知进行了测量和表征。居住者的反应表明，博物馆内部的热条件不能令人满意地满足ASHRAE标准55，因为只有78%的居住者对他们的环境感到满意。并对实际平均投票数（AMV）和预测平均投票数（PMV）进行了比较。Fanger模型给出的PMV中性操作温度为22.2°C，而本研究中使用的平均热感觉投票（MTSV）问卷数据给出的中性操作温度更高（22.5°C）。最佳手术温度为22.3℃。三个展厅的最低气温低于澳大利亚维多利亚博物馆推荐的18-22°C温度范围的下限。相对湿度（RH） 55±5%的最佳范围，室内平均湿度过高。每个廊道的平均风速≤0.15 m·s−1，令人满意。研究结果对热带地区博物馆建筑的供暖、通风和空调系统的节能设计具有重要的指导意义。
A field study was conducted to investigate the thermal environment and occupants’ comfort in the National Museum of Malaysia. The occupants’ thermal perceptions in the museum were measured and characterised. The response of the occupants has indicated that the thermal conditions inside the museum did not satisfactorily fulfil the ASHRAE Standard 55, because only 78% of the occupants were satisfied with their environment. Besides, actual mean vote (AMV) and predicted mean vote (PMV) were compared. The Fanger’s model gave a neutral operative temperature of 22.2°C from the PMV, whereas the questionnaire data used in the mean thermal sensation vote (MTSV) of the present study gave a higher value (22.5°C) for the neutral operative temperature. The preferred operative temperature was found to be 22.3°C. The minimum air temperature in three galleries was below the lower limit of the temperature range of 18–22°C as recommended by Museums Australia Victoria. The mean indoor humidity was too high compared to the optimal range of 55 ± 5% relative humidity (RH). The mean air velocity, ≤0.15 m·s−1, in each gallery was satisfactory. Findings of this study are very useful for designing heating, ventilating and air-conditioning (HVAC) systems with energy-saving methodology for museum buildings in tropical regions.
