Abstract

In this paper we examine the computational speed and accuracy of the computational fluid dynamics used within our proposed AC-Guide. Our previously proposed AC-guide improves air quality in a way that is not possible with the air conditioning features already installed in offices and residences. It prompts users to open and close windows and doors and operate switches on appliances other than air conditioning using voice and cell phone notification functions. Within this system, the key technology is to quickly predict how indoor temperature, humidity, air velocity, and CO2 concentration will change when certain actions are taken. As an initial step in our research, we built a small air-conditioning experimental setup and compared the results of experiments with a simplified model with those predicted by computational fluid dynamics.
