The Performance Verification of the Air-Conditioning System of the Architecture & Environment Building and the Comfort Evaluation of the Provided Thermal Environment : A Study on Winter Measurements Taken in the Large Drawing Room

Abstract

In July 2014, the construction of the Architecture & Environment Design building(No.5 Building)was completed at Kanto Gakuin University. This report aims to verify the performance of the air-conditioning system that was operated during winter time in the large-space drawing room on the top floor of the building, and to evaluate the thermal environment provided in the drawing room by the air-conditioning system. The air-conditioning system is configured with a duct system that employs a heat pump air conditioner, a floor type air-conditioning system that employs a gas heat pump(GHP)and ceiling fans. The vertical temperature distribution and the predicted mean vote(PMV)of the room atmosphere, which were obtained during operation, are used as indices, while the results of a questionnaire about warm/cold feelings are also taken into consideration, to evaluate the comfort
