| Abstract |
This study aims to present the basic data for the establishment of indoor optimal thermal environment in housing for the aged by thorough field and subject response survey and experiment in model living room. As the first pace of study, the thermal-environment factors were defined by the measurement of physical thermal environment element (dry bulb temperature, radiative temperature, relative humidity, and air velocity) and the environmental needs of the residents was investigated through the questionary survey of the response to thermal environment in welfare facility with radiation heating for the aged in Teagu during winter in 2001. As a result of it, a model living room was designed and structured as a actual domestic room. Physical thermal-environment factors and environmental needs of the occupants in radiative heating space were examined thoroughly by measuring physical thermal environment element and investigating subjective response according to varied condition. The result of study can be summarized as follows; The value of the floor temperature in model living room was 30～34℃ according to temperature control of a constant temperature water tank. In particular, the value of the floor temperature was 33～34℃ and air temperature was 27～28℃ when the constant temperature water tank was 70～80℃. At this point, the value(38～42%) of indoor relative humidity was in the standard(37～48%) of relative humidity for comfort. And also, occupants felt somewhat warm at the body on the whole as well as at the lower part of the body. However, the response of occupants was uncomfortable comparatively at the upper part of the body. The reason of that was seemed to be lack of ventilation and stifling atmosphere of the spot. |
