| Summary: | 碩士 === 東南科技大學 === 機械工程研究所 === 101 === This article is aimed at the effectiveness improvement and costs reduce on the air conditioning of hospital by interchanging rotating disk module of a blower motor to match the different speed. The experimental models are formed by different main wind drum and motor rotating disc to be model A (rotating disc 150 mm, wind drum 300 mm), model B (rotating disc 140 mm, wind drum 300 mm), model C (rotating disc 150 mm, wind drum 280 mm), and model D (rotating disc 140 mm, wind drum 280 mm). The data of measured points are tested and got at the different models to analyze the variation of the flowrate and CO2 concentration . It shows that model D is more economical of 3 % power saving than model A because of flowrate increase 9 % and CO2 concentration decrease 0.75 % at model D. Model D can improve the overall performance by slightly cost increase and be recommended more economically for this medical air conditioning.
