The use of night cooling ventilation in addition of phase change materials (PCMs) is a very powerful strategy
for reducing the cooling demand of buildings. Nevertheless, there are inherent drawbacks in the way
things have been doing so far: (a) The limited area of contact between PCM and the air; (b) the very low
convective heat transfer coefficients which prevents the use of significant amounts of PCM and (c) the
very low utilization factor of the cool stored due to the large phase shift between the time when cool
is stored and time when it is required by the building. In this paper, we present innovative solutions using
PCM to overcome the above situation. Compared with existing solutions, innovative solutions proposed,
increase the contact area between PCM and air by a factor of approximately 3.6, increase the convective
heat transfer coefficient significantly, and improve the utilization factor due to the inclusion of active
control systems which allow the cold stored be actually used when required. |
