Supply airflow control algorithm of a floor-standing room air-conditioner to achieve thermal comfort for residential housing in summer

A review of human thermal comfort in the built environment

“…Other studies in climatic chambers, involving an individually/personally controlled system were performed in Denmark (with mechanisms for facial ventilation and heating [123] and ventilation, heating and cooling [124], radiant and convective cooling [125] and another system using a ductless personalized ventilation in conjunction with displacement ventilation [126]), in Hong Kong (chair-based personalized ventilation -PV-system) [127], in Lebanon (low-mixing ceiling-mounted personalized ventilator system) [128], in Hungary (a novel PV system with air flow coming alternatively from three different directions) [129,130], in the United States (heated/cooled chair [131], ceiling fans [132] and floor fans [133]), in South Korea (floor-standing room airconditioner) [134], in China (electric fans were placed in front of subjects, directed at their faces) [135] and in Japan (chair equipped with fans) [136]. Results of the personalized conditioning systems with regard to thermal comfort were equal or better than conventional cooling systems [122][123][124][125][126][128][129][130][131][132].…”

Indoor physical field estimation from sparse sensor observations

“…On the other hand, the indoor temperature observed from sensor networks was used as feedback information for indoor temperature control [18][19][20][21]. Indoor thermal maps and air velocity fields can be used to analyze indoor airflow for localized air-conditioning [22][23][24][25],…”
