Description

Title: Door Entrance System

The present invention relates to a door entrance system for connecting a first area and a second area with a low energy transfer between the areas. It specifically relates to a revolving door entrance system for connecting a first area and a second area.

Background of the invention

A door entrance system typically is used for allowing people to enter and leave public buildings such as stores, offices, garages and museums etc., where a large number of persons pass through each day. Buildings in areas with high pollution can have problems with polluted air entering into the buildings and the door entrance system is one of the openings in the buildings where pollution enters, since the doors of the door entrance system is opened and closed frequently.

The pollution can for instance relate to buildings in cities with general smog problems, building located next to roads with high traffic or buildings located close to areas with a high concentration of allergenic particles (or other particles) that enters into the building. To create a sustainable environment for the people working and living in such buildings there is thus a need for such polluted air to be kept out of, or at least reducing the amount entering the building via the door entrance system.

Further, buildings in areas with a temperature difference between the indoor temperature of a building and the outdoor temperature, colder or hotter, can have problems with that energy in the air from the outdoors is mixed with the indoor air, i.e. the indoor air is heated or cooled, and the door entrance system is one of the openings in the buildings where the energy is transferred since the doors of the door entrance system is opened and closed frequently. To reduce the energy consumption of buildings that is used to temper the air in the buildings, the energy transferred from the outdoor air to and from the indoor air should be as low as possible. To create a sustainable environment for the people working and living in such buildings and to reduce the energy consumption, there is thus a need to reduce the energy in the air that is transferred between the indoors and outdoors of the door entrance system of a building.
