Abstract

In this paper, we proposed a plan to maintain comfortable indoor air quality in nursing homes by suggesting ways to reduce items temporarily exceeding the reference values through real-time concentration variation analysis of indoor air quality. Five items including PM10, CO2, CO, VOC, and Radon are measured at nursing homes in spring (April) and autumn (September) was carried out and all of the measured items were analyzed to satisfy the criteria set by the Indoor Air Quality Control Act. As a result of the analysis of the real-time concentration change, the concentration of CO2 was close to the reference value based on the number of occupants in the sick room. Due to the disinfectant (alcohol) used to disinfect and the auxiliary tools (adhesive) used in the operation of the program such as making and coloring, it was analyzed to temporarily exceed the standard value in the hall. In conclusion, it is possible to provide pleasant indoor air quality and contribute to securing the nursing home's competitiveness if periodic ventilation, natural disinfectant and eco-friendly product are used in consideration of the thermal environment.

본 연구는 실내공기질의 실시간 농도변화 분석을 통하여 일시적으로 기준값을 초과하는 항목에 대하여 원인 분석을 통하여 요양원의 쾌적한 실내공기질을 유지하기 위한 방안을 제안하고자 실시하였다. 요양원에서 미세먼지(PM10), 이산화탄소(CO2), 일산화탄소(CO), 휘발성유기화합물(VOC), 라돈(Radon) 등 5개 항목에 대하여 다목적 홀에서 봄(4월), 가을(9월)에 각1회 측정을 실시한 결과 측정 항목 모두 실내공기질 관리법에서 정한 기준을 만족하는 것으로 분석되었다. 실시간 농도 변화에 대한 분석 결과 병실의 경우 이산화탄소의 농도가 재실자 수에 의하여 기준치에 근접하는 수준을 보였으며 다목적 홀의 경우 이산화탄소 및 미세먼지는 주간보호 대상 어르신 및 근무자의 프로그램 활동과 휘발성유기화합물의 경우 식탁을 소독하기 위하여 사용하는 소독제(알코올) 및 만들기, 색칠하기 등의 프로그램 운용시 사용되는 보조도구(접착제)로 인하여 일시적으로 기준치를 초과하는 것으로 분석되었다. 결국 측정 대상 요양원에서는 온열환경을 고려하여 주기적인 환기, 천연소독제 사용 및 친환경 접착제 사용 등을 실시한다면 쾌적한 실내공기질 제공이 가능하고 요양원의 경쟁력 확보에도 기여할 것으로 판단된다.
