本文介绍了医院热舒适性研究的结果。对热带地区医院的热舒适温度范围进行了实地调查。热可接受性评估是为了检查热带地区的医院是否符合ASHRAE标准-55 80%可接受标准。共有四家医院的114名住客参与了这项研究。现场研究的结果显示，只有44%的受检地点符合ASHRAE标准55中规定的舒适度标准。调查还检查了医院不满意的预测百分比。结果显示，49%的人对医院内的热环境感到满意。现场调查分析表明，马来西亚医院的中性温度为26.4摄氏度，满足90%居住者的舒适温度范围在25.3-28.2摄氏度。现场研究结果表明，与ASHRAE标准(2003)中规定的温度标准相比，马来西亚人在医院环境中需要更高的舒适温度。此外，实际平均投票和预测平均投票(PMV)之间的显著偏差强烈地表明，PMV在热带医院的应用中不可能没有错误。实际意义热带医院热舒适温度范围的新发现可以作为建筑服务工程师和研究人员的重要指南，他们打算在热带运营的热舒适水平可接受的医院将供暖、通风和空调系统的能耗降至最低，并改善其工作人员的工作表现和幸福感。
P>This article presents findings of the thermal comfort study in hospitals. A field survey was conducted to investigate the temperature range for thermal comfort in hospitals in the tropics. Thermal acceptability assessment was conducted to examine whether the hospitals in the tropics met the ASHRAE Standard-55 80% acceptability criteria. A total of 114 occupants in four hospitals were involved in the study. The results of the field study revealed that only 44% of the examined locations met the comfort criteria specified in ASHRAE Standard 55. The survey also examined the predicted percentage of dissatisfied in the hospitals. The results showed that 49% of the occupants were satisfied with the thermal environments in the hospitals. The field survey analysis revealed that the neutral temperature for Malaysian hospitals was 26.4 degrees C. The comfort temperature range that satisfied 90% of the occupants in the space was in the range of 25.3-28.2 degrees C. The results from the field study suggested that a higher comfort temperature was required for Malaysians in hospital environments compared with the temperature criteria specified in ASHRAE Standard (2003). In addition, the significant deviation between actual mean vote and predicted mean vote (PMV) strongly implied that PMV could not be applied without errors in hospitals in the tropics.Practical ImplicationsThe new findings on thermal comfort temperature range in hospitals in the tropics could be used as an important guide for building services engineers and researchers who are intending to minimize energy usage in heating, ventilating and air conditioning systems in hospitals operating in the tropics with acceptable thermal comfort level and to improve the performance and well-being of its workers.
