室内温度或将根据人体需求完成自动调节

2017-04-20              中国环保网

芬兰国家技术研究中心(VTT)日前主导了一项新的研究,该项目名为HumanTool,是一种新型的室内温度控制概念,通过HumanTool,室内空间温度可根据个人需求进行自动调节。这样一来,在无人的房间内,关闭无用的加热装置或者制冷装置,就可有效实现室内节能。该项目的结果将最终形成一个新的室内温控节能产品。

据统计,人类在室内与室外所用时间的占比大概在9:1,因此,我们对室内温度的冷热感知会在很大程度上影响着我们的生产力和舒适度。基于这点考虑,HumanTool项目意在加强室内温控能力,从而提高由温度影响的舒适度,进而提高用户的健康指数和幸福感。

该项目始于去年秋天,涉及内容包括医院和办公室条件下对冬夏两季智能温控制冷和加热情况的实际测试和研发。第一批试点单位为VTT位于艾斯堡的Digitalo办公室、塞伊奈约基中央医院和库奥皮奥大学医院。在医院试点中,测试工作首先从办公区开始,然后才延伸到治疗区。作为HumanTool的终端用户,医护人员和病人的使用体验将会被集中收集并反馈回项目组用于进一步研发。

“我们将利用VTT研发的人体温度模型(HTM)对各类用户群体的温度感知情况进行评估,而后再将这些评估结果纳入舒适节能建筑设计的考量中。鉴于现在设备监测的数码解决方案成本低且效率高,在温控方面,我们将用到最新的技术”,VTT项目经理派卡.托马拉如是说。

据悉,项目结果将于2018年底完成,届时,该项目将被用于办公室、医院、酒店、学校和车辆等各类场所。由VTT协调主导的HumanTool开始于2016年10月,项目赞助方和合作伙伴分别是VTT、塞伊奈约基中央医院、库奥皮奥大学医院、芬兰国有地产企业Senate Properties、西门子、欧博诺、瑞典精密工具制造企业Granlund、Mecastep公司和新北欧工程公司。

关于人体温度模型HTM方法:

对人体热度感知的评估是基于人体解剖学和生理学完成的。HTM方法可用于评估个体特征——性别、年龄、身体质量指数和肌肉组织(骨、肌肉、脂肪和皮肤)等。温度和湿度会在解剖学意义上的人体、服装以及外部环境之间发生转移,借助这些信息,可以有效确定身体组织的局部温度,从而计算出身体不同部位对局部温度的不同感知情况。

原文:Indoor temperatures in buildings of the future will automatically adjust to user needs

The HumanTool project being led by VTT Technical Research Centre of Finland involves the testing of new indoor temperature control concepts for adjusting spaces to individual needs. Energy is saved when unused rooms can be left unheated or uncooled. The final result of the project will be a completely new product.

We spend around 90% of our time indoors. Our experience of thermal sensation is important to productivity and comfort, and is mainly affected by a room''s temperature level. The HumanTool project aims to enhance the comfort level of indoor temperatures, which affects the thermal comfort, health and well-being of a facility’s users.

Begun last autumn, the project will involve the practical testing and development of a smart temperature control concept in hospital and office conditions during two heating and cooling seasons. The first pilot sites will be VTT’s main office, Digitalo, in Espoo, the Seinäjoki Central Hospital and Kuopio University Hospital. In the hospitals, testing will begin in office premises and then proceed to patient facilities.

The experiences of various end-users of the rooms, such as staff and patients, will be gathered.

“We will use the Human Thermal Model (HTM) method developed by VTT. We will evaluate the thermal sensations of various user groups, which will be taken into account in the design of comfortable and energy-efficient buildings. Because digital solutions for facility monitoring are now cost-efficient, we will use the latest technology for temperature control,” says project manager Pekka Tuomaala of VTT.

The results will be ready at the end of 2018 and can be applied in places such as offices, hospitals, hotels, schools and in vehicles.

VTT is coordinating the HumanTool project, which began in October 2016. The project sponsors and partners are VTT, the Seinäjoki Central Hospital, Kuopio University Hospital, Senate Properties, Siemens, Uponor, Granlund, Mecastep and New Nordic Engineering.

Further information on the Human Thermal Model HTM method:

People’s evaluation of thermal sensation is based on individual anatomy and physiology. The HTM method is used to assess the impact of individual characteristics – gender, age, body mass index and muscularity – on the volumes of various tissue types (bone, muscle, fat and skin). The transfer of warmth and moisture between a person''s anatomy and clothing and the environment can help to determine the local temperature of body tissues. This can be used to calculate local thermal sensations in different parts of the body.
