Abstract

Due to the high energy consumption of the air conditioner (AC), the desk fan usage is a common thermal adaptation that promotes energy saving and provides indoor comfort. However, the occupants tend to demand a cooler environment as the comfort level is still low even in the presence of a personal desk fan. The question on whether the wind direction from a desk fan is meaningful or not towards the thermal comfort of office occupants remains vague. Similarly, the direction of the wind preferred by occupants to maintain their comfort has not been investigated. Therefore, this paper aims to propose a research idea to study the indoor thermal comfort of office occupants and determine the suitable wind direction from the desk fan that can potentially mitigate the thermal sensation of the occupants. This research will be a combination of field measurement and subjective thermal questionnaire study involving around 10 respondents and several fan configurations. There are three stages of the measurement, namely Stage 1 (no-fan configuration), Stage 2 (single fan configuration), and Stage 3 (dual fan configuration). The pre-measurement result conducted on two students showed that the respondents may have a different preferable wind direction affecting on their comfort.
