Design and Testing of An Evaporative Cooling System using An Ultrasonic Humidifier


File Size: 1.31 Mb

Description
This paper topic was chosen at the behest of the course coordinator, Dr. Raghavan, who wanted work to be performed with a client’s (Plastique Frapa Inc.) humidifying technology in relation to part of his research interest area: postharvest storage.

This paper was part of a senior year design project and reports the results of the experiment work that was performed in analyzing the effectiveness of the designed setup. Aside from the topic definition, the project was self-directed in terms of methodology and analysis. Although it should be noted that research associates of the department were instrumental in solving problems that occurred throughout the experimentation.
