Researchers by the Polytechnic University of Madrid (UPM) have performed a study which reveals that the use of high efficiency air curtains results in significant improvements in efficiency and energy savings.
The study, published in the journal Energy and Buildings, analyzes in depth the energy savings and hygrothermal conditions improvement due to installation of air curtains in commercial doors with heavy pedestrian traffic.
It has been used as object of study a shop located in Eastern Spain air-conditioned with direct expansion cassette splits and outdoor conditions of heat and high humidity.
In this study the energy costs and air conditions are analyzed in three different situations; without an air curtain, with conventional air curtain and with a high efficiency air curtain
Finally, it proves that the use of high efficiency air curtains means higher energy savings over 30% of the entire HVAC Store.
