Abstract

This research project presents a study on performance of walk-in-stability chamber. The purpose of this study is to determine the chamber characteristic and performance before any experimentation were carried out in this chamber. Data collection was taken starting on December 2006 until April 2007. The physical measurement includes air temperature, relative humidity, the concentration of carbon monoxide (CO) and carbon dioxide (COz) gases including the level of noise that occur inside the chamber. The chamber was operated daily, minimally from eight (8) to ten (10) hours. The experiment was set on the range of air temperature between 10 "C to 40 OC and relative humidity is between 60%rh to 90%rh. These parameters were measured by four (4) sensors that were installed in the ceiling of the chamber at three (3) meter heights. The actual data h m the measurement were compared and validated with the setting parameter. During the operation, normaIly the air temperature and relative humidity will fluctuate from the actual setting. The concentration of gases was measured using Indoor Air Quality (IAQ) probe and the level of noise was measured using Sound Level Meter (SLM). Data was collected at least for two (2) hours. A few standards such as Code of Practice on Indoor Air Quality ASHRAE Standards 55-2004 and 62-2004 have been used to validate the collected data. The expected results were on the actual air temperature and relative humidity compared to the setting parameters where a linear regression equation can be formulated to find the characteristics of the chamber.
