A hygiene management device for an entrance hall includes a fan assembly, a duct and an air discharger that discharges air toward a person at positions around the person in consideration of a person's height or such that an air discharge angle is adjusted upward/downward in consideration of a person's face position or a person's height.

A hygiene management device for an entrance hall includes a fan assembly which generates an air blowing force, a function module which provides a storage space, an air discharger which discharges air toward a person, and an opening/closing unit which selectively stops an air flow. Particularly, the opening/closing unit is configured such that air is supplied into at least one of the function module and a duct unit or simultaneously into both the function module and the duct unit.

A hygiene management device for an entrance hall and the control method of the same are proposed. The hygiene management device may be installed in an entrance space, and when a person is detected at a preset position, distance between an air discharger and the person may be detected. When the detected distance is within a reference distance, air may be discharged. In addition, an air discharge condition suitable for a person may be preset, and when the person enters the entrance hall, the person's face may be detected, and air may be discharged to the person according to the air discharge condition preset for the person.

A hygiene management device for an entrance hall is designed to emit far-UV light from upper and lower sides toward a person by reflecting the far-UV light emitted from the upper side to the person's lower body by a reflector located at the lower side, and reflecting the far-UV light emitted from the lower side to the person's upper body by a reflector located at the upper side. Accordingly, a sterilization effect on the person is improved.

[SUMMARY]

[Problems to be Solved]

To provide an air curtain apparatus that is small and simple, capable of separating a space, and capable of preventing entry of foreign matters such as droplets from one subspace into the other subspace.

[Solution]

An air curtain apparatus 1 includes a plurality of blowers 11 arrayed in an up-down direction and a plurality of second blowers 21 arrayed in the up-down direction. An air inlet port 23 included in the blower 21 faces an air outlet port 14 included in the blower 11. In a pair of the blower 11 and the blower 21, the blower 11 blows out a helical air current SA1 from the air outlet port 14, and the blower 21 sucks in the helical air current SA1 from the air inlet port 23. The air curtain apparatus 1 forms an air curtain AC1 with a plurality of the helical air currents SA1, the plurality of the helical air currents SA1 being blown from the plurality of the air outlet ports 14 and sucked into the plurality of air inlet ports 23.

Systems and methods for limiting infiltration of cabin air into the flight deck of an aircraft, where the systems include at least one upper nozzle disposed adjacent to and above an outer upper edge of a flight deck doorway and directed downwardly, and at least one lower nozzle disposed adjacent to and below an outer lower edge of the flight deck doorway and directed upwardly; a conduit system to deliver air from a flight deck air supply to the upper and lower nozzles; and an airflow controller configured to provide sufficient air flow from the flight deck air supply to the upper and lower nozzles to create directional airstreams across the gaps between the closed flight deck door and the upper and lower edges of the flight deck doorway, so that the airstreams limit infiltration of cabin air into the flight deck via the gaps.

A tabletop laminar flow HEPA filtered air curtain, for use as a bio-safety separation barrier for the personal protection of individuals from a respired aerosol, is provided. The air curtain has a rectangular cabinet. The cabinet is partitioned into a fan housing, in fluid communication, with a HEPA filter box. The fan housing has an air intake. A fan assembly is mounted in the fan housing. The fan assembly has a ducted housing, in fluid communication with the ambient air intake, and a blower. A horizontal HEPA filter is mounted in the filter box so that a blower discharge passes through the HEPA filter, and upwardly and uniformly through an elongated laminar flow nozzle in a top wall of the filter box.

Provided is a cashier station attachment for creating a vertical air curtain between a retailer and a customer. The device includes a substantially planar body with an internal chamber and an open side with a diffuser, an attachment means for attaching the device to a cashier station, and a means for forcing air into the internal chamber and out of the diffuser. The forced air from the chamber creates an air curtain, which is an invisible barrier between a retailer and a customer. The air curtain prevents the spread of contaminants, pathogens, and the like that are expelled from the mouth or nose of a person on one side of the air curtain from contacting a person on the other side. The device can be retrofitted onto any preexisting cashier station and can be readily removed as desired.

A module air curtain and recirculation system that can be incorporated into various tables and workstations that provides 1) an effective air curtain between individuals, 2) a reduction of harmful viruses and 3) the ability for two or more people to be in close proximity without having to wear personal protective equipment such as face masks. The apparatus for indoor air filtration and conditioning creates an air curtain between and around people. The device captures aerosolized droplets expelled from occupants and recirculates cleaned air to operate the air curtain while greatly increasing effective air changes per hour in spaces it is employed. While portable room air purifiers are used to improve the air quality of indoor spaces and reduce particles, allergens, and viruses, they do little to stop the person-to-person transmission of viruses. This device solves these deficiencies. Through applied effort, ingenuity, innovation and testing these issues have been solved by the embodiment of the presently disclosed modular system. Employment of this system can allow businesses, schools and restaurants to resume more normal activity.
