A Review on Airflow and Temperature Distribution in A Residential Building with an under Floor Air Distribution System

This paper presents the investigation to evaluate an under floor air distribution (UFAD) system existed in a Residential building. Despite the fact that UFAD systems are being applied in the field in increasing numbers, there is a strong need for an improved fundamental understanding of several key performance features of these systems. Recent trends in today's Residential environment make it increasingly more difficult for conventional centralized systems to satisfy the environmental preferences of individual persons using the standardized approach of providing a single uniform thermal and ventilation environment. Under floor air distribution (UFAD) is an air distribution strategy for providing ventilation and space conditioning in buildings as part of the design of an HVAC system. UFAD systems use an under floor supply plenum located between the structural concrete slab and a raised floor system to supply conditioned air through floor diffusers directly into the occupied zone of the building. Thermal stratification is one of the featured characteristic of UFAD system, which allows higher thermostat set points compared to the traditional overhead systems (OH). CFD models have been used to study indoor air quality (IAQ) problems, pollutant distributions, and performance of UFAD systems. The increasing developments of computational fluid dynamics (CFD) in the recent years have opened the possibilities of a low-cost, yet effective, method for improving UFAD systems in design phase, with less experiment required.
