On te Improvement of the Thermal Environment under Air Conditioning at Homes for the Aged

本研究的目的是通过对养老院空调和供暖系统的热环境调查，探讨空调和供暖系统的管理和改进。1997年，我们对他们的空调和供暖方式做了一次访谈调查，在冬天，我们对供暖家庭的热环境进行了调查。在1998年。我们在夏季对有空调的家庭进行了调查。我们在不同气候地区的6个家庭进行了调查；新泻县有4户，爱知县有2户。结果总结如下。家里的空调都是风机盘管，安装在房间中央的天花板上。至于供暖系统，新泻市有三户人家安装了地暖系统。他们根据外面的天气情况使用空调。在爱知县的家庭中，空调断断续续地打开和关闭，在调查过程中，温度计在许多天内都超过了30‰。暖气房的温度有点高。爱知县家庭当天的平均气温较低。新泻市的四所房屋都进行了加湿处理。其中两人在客厅里使用超声波加湿器。在另外两个家庭，空调安装了加湿器。然而，两个家庭中的一个家庭的加湿功能有一些工作的可能性，但在检查后工作。在所有的家庭中，工作人员都担心供暖时湿度低。为了防止流感等疾病的感染，有必要通过降低温度来提高相对湿度，并重新研究加湿方式。

The purpose of this study is to examine the management and improvement of the air-conditioning and heating system based upon the survey on the thermal environment under air-conditioning and heating at homes for the aged. in 1997, we did an interview survey about their ways of air-conditioning and heating, and in winter, we conducted a survey of the thermal environment at heated homes. In 1998. we conducted a survey at air-conditioned homes in summer. We did our survey at 6 homes in regions of different climate ; 4 homes in Niigata prefecture and 2 homes in Aichi prefecture. A summary of the results is as follows.1. The air-conditionings of the homes are all fan-coil units and they were installed in the center of the room on the ceiling. As for heating systems, three homes in Niigata had floor heating installed.2. They were using air-conditionings according to the weather conditions outside. At the homes in Aichi, air-conditions were turned on and off intermittently, and the thermometer registered over 30ﾟCC on many days during the survey.3, The temperature of the heated rooms was a little high. The average temperature of the day was lower at homes in Aichi.4. All the four homes in Niigata were humidified. Two of them were using ultrasonic humidifier for domestic use in their living rooms. At the other two homes, humidifiers were installed in the air-conditionings. However, the humidifying function at one home of the two had some possibilities to work but worked after checking.5. At all the homes, the staff worried about the low humidity while heating. In order to prevent the infection of disease such as influenza, it would be necessary to raise relative humidity by setting up the temperature lower and to reexamine the ways of humidifying.
