Abstract
A push through conditioned air vestibule unit includes an air vestibule having a top side, a first lateral side, and a second lateral side forming a passage through the unit. Movable barrier members are attached to the unit to reduce external air flow through the passage. Return air ducts are configured to circulate air to an air moving device and a temperature conditioning device. Thermal and humidity sensors measure temperature and humidity of the passage and an external room, and a system controller controls the temperature of air moved into the passage using the temperature conditioning device if the partial pressure of moisture vapor internal to the passage is not greater than or equal to the partial pressure of moisture vapor external to the passage.
