Description:

The present study is aimed at seeking a better understanding of the thermodynamics involved with the air distribution strategies associated with UFAD systems and its impact on the energy saving dynamics.
Thus objectives are:

• Experimental investigation of (a) Under Floor Air Distribution (UFAD) plenum heat gain, (b) solar heat gain inward flowing fraction and (c) radiation-convection split of internal heat gains (with and without occupants) on the cooling load dynamics in a UFAD system,
• Development of a better understanding as to how each of the above factors impact the load dynamics during design of buildings with UFAD systems as opposed to conventional systems,

Approach :

Survey of Operational Buildings
A test will be performed on an UFAD system installed in a commercial or a residential building. The goal is to identify buildings that represent a cross section of the UFAD systems currently in operation. Measurements will be taken in these buildings to allow the airflow and temperature conditions to be generally understood. The primary focus will be temperature measurements, performed with portable recording and hand held instruments or gathered from the existing DDC systems and trends. The measurements at the under floor supply grilles will be carried out in a manner that can determine the general temperature distribution to a level that would allow some conclusions to be drawn on the heat gain pattern. A similar approach will be taken for return plenum measurements.
