Abstract

Increased air velocity improves thermal sensation in warm humid climate under certain conditions. In halls and enclosed public zones, a great volume of room air needs to be exchanged with fresh air. This is crucial to keep the air quality up to a desired degree. Air conditioning requires relatively high amount of energy for cooling and dehumidification, especially by high moisture content. Although fresh air can be provided by exposing the space to the outdoor environment via windows or moving partitions, improving thermal sensation and air quality in such space will not take place in calm wind conditions due to the lack of air movement. This paper investigates the effect of inducing outdoor air via ceiling confluent high velocity air supply to mix it with and eventually replace existing air in the semi-outdoor space. The generated results from the conducted CFD simulations indicate high air change rate, low air velocity at human height and increased thermal comfort without the need for cooling or dehumidification. The presented method of room conditioning suggests a low energy solution for spaces in adjacent location to the outdoor context that can generate new and more urban spaces.
