【摘要】：人类的生活水平不断提高,人们对健康的关注程度逐渐增加,医院又是预防疾病和管理健康最主要的机构,所以医院对人们越来越重要。近年来关于医院建筑的研究较多,但是关于医院病房内病人热舒适的研究相对较少。本文依托国家自然科学基金项目《医疗建筑热湿环境对人体健康影响研究》(No.51278506),对病人新陈代谢及病房人员热舒适展开研究。国内关于医院病房病人热舒适的研究主要以Fanger教授的PMV模型为基础,得到病人的热中性温度等参数,没有考虑病人患病的特殊性。已有研究表明病人的新陈代谢率与健康人不同,所以将健康人的新陈代谢率直接应用到病人热舒适研究是不妥的。首先,本文通过对国内外人体能量预测研究成果的分析整理,找到了14个现在应用广泛的能量预测公式,通过综合分析预测公式在准确率、偏差等方面性能,发现Ireton-Jones1992公式可以较为准确的预测病人能量代谢。因此本文用该公式计算病人的能量代谢,将其代入Fanger教授的PMV模型对病人的热舒适进行研究。然后,对重庆某所三级甲等医院普通病房进行了冬季和夏季的现场实验,了解病房热环境及病人热舒适的情况,共获得有效问卷1078份。根据调研数据,用Ireton-Jones1992公式计算得到的得到的冬、夏季病人平均新陈代谢率分别为42.63 W/、42.56 W/,均大于《民用建筑室内热湿环境评价标准》推荐的40.71 W/。采用Bin法,得到了病房病人实测和预测热中性温度,将此结果与规范给出的新陈代谢率得到的热中性温度进行比较,发现两种方法得到的结果差异不明显。将病房科室分为内科和外科,发现内、外科疾病对热舒适的影响较小。最后,根据病人和陪护人员的热感觉投票,分别得到了病人和陪护的可接受温度区间,取20%不满意率的交集部分,得到了病房人员的可接受温度。冬、夏季的病房可接受温度区间分别为20.4℃~22.4℃和24.6℃~26.5℃。
[Abstract]:With the improvement of human living standard, people pay more and more attention to health. Hospital is the most important organization to prevent disease and manage health, so hospital is more and more important to people. In recent years, there are more researches on hospital buildings, but there are few researches on the thermal comfort of patients in hospital wards. Based on the project of National Natural Science Foundation of China (No.51278506), this paper studies the metabolism of patients and the thermal comfort of ward staff. The domestic research on the thermal comfort of hospital ward patients is mainly based on the PMV model of Professor Fanger. The parameters such as thermal neutral temperature of patients are obtained without considering the particularity of patients' illness. Studies have shown that the metabolic rate of patients is different from that of healthy people, so it is inappropriate to directly apply the metabolic rate of healthy people to the study of patients' thermal comfort. First of all, by analyzing the research results of human body energy prediction at home and abroad, 14 widely used energy prediction formulas are found in this paper. It is found that the Ireton-Jones1992 formula can accurately predict the energy metabolism of patients. In this paper, the energy metabolism of patients is calculated by this formula, and the thermal comfort of patients is studied by inserting it into Professor Fanger's PMV model. Then, the field experiments in winter and summer in general ward of a Grade 3A hospital in Chongqing were carried out to understand the thermal environment and thermal comfort of the patients, and 1078 valid questionnaires were obtained. According to the investigation data, the average metabolic rate in winter and summer was 42.63 W / r and 42.56 W / r, respectively, calculated by Ireton-Jones1992 formula, which was higher than the 40.71 W / r recommended by the Standard for evaluating the Indoor Thermal and humid Environment of Civil buildings. The thermal neutral temperature was measured and predicted by the Bin method. The results were compared with those obtained by the standard metabolic rate. There was no significant difference between the two methods. The ward departments were divided into internal medicine and surgery, and the effect of surgical diseases on thermal comfort was found to be small. Finally, the acceptable temperature range of patient and attendant is obtained according to the heat sensation of patient and attendant, and the acceptable temperature of ward staff is obtained by taking the intersection part of 20% dissatisfied rate. The acceptable temperature ranges in winter and summer are 20.4 鈩，
