Studies concerning indoor thermal conditions are very important in defining the satisfactory comfort range in health care facilities.
This study focuses on the evaluation of the thermal comfort sensation felt by surgeons and nurses, in an orthopaedic surgical room of a Portuguese hospital.
Two cases are assessed, with and without the presence of a person. Computational fluid dynamic (CFD) tools were applied for evaluating the predicted mean vote (PMV) index locally.
Using average ventilation values to calculate the PMV index does not provide a correct and enough descriptive evaluation of the surgical room thermal environment. As studied for both cases, surgeons feel the environment slightly hotter than nurses. The nurses feel a slightly cold sensation under the air supply diffuser and their neutral comfort zone is located in the air stagnation zones close to the walls, while the surgeons feel the opposite. It was observed that the presence of a person in the room leads to an increase of the PMV index for surgeons and nurses. That goes in line with the empirical knowledge that more persons in a room lead to an increased heat sensation.
The clothing used by both classes, as well as the ventilation conditions, should be revised accordingly to the amount of persons in the room and the type of activity performed.
关于室内热环境条件的研究对于确定医疗保健设施中令人满意的舒适范围非常重要。
本研究聚焦于评估葡萄牙一家医院骨科手术室中外科医生和护士所感受到的热舒适感。
评估了两种情况，有人在场和无人在场。应用计算流体动力学（CFD）工具局部评估预测平均投票（PMV）指数。
使用平均通风值来计算PMV指数并不能对手术室热环境提供正确且充分的描述性评估。对两种情况的研究均表明，外科医生感觉环境比护士感觉的略热。护士在送风扩散器下方会感到稍有凉意，且其舒适中性区位于靠近墙壁的空气停滞区域，而外科医生的感受则相反。观察到室内有人会导致外科医生和护士的PMV指数增加。这与经验认知相符，即室内人数增加会导致热感增强。
应根据室内人数和所进行活动的类型，相应地对外科医生和护士这两类人员的着装以及通风条件进行调整。
