Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention relates to an air conditioning ceiling equipment unit in a line ceiling system.

``Prior Art'' Line ceiling systems in buildings, underground malls, etc. usually use automatic variable air conditioning equipment. In this equipment, a ceiling frame arranged in a lattice pattern supports an equipment plate with an air outlet and an equipment plate with an inlet, and these are connected to an air supply duct and an exhaust duct arranged in the ceiling. communicate with each other,
Further, an air volume variable device is provided in the middle of the air supply duct, and the air volume variable device is automatically controlled by a temperature detector placed in the room or in the passageway.

Note that the air outlet and suction port may be incorporated into lighting equipment (for example, Utility Model Publication No. 53-125320).
issue).

``Problem that the invention attempts to solve'' However, in recent years, from the perspective of earthquake resistance, it has become common to fix equipment plates, ceiling panels, etc. with anti-floating metal fittings, and therefore, even though it is a system ceiling, However, it is necessary to provide a dedicated inspection opening for inspecting equipment such as an air volume variable device in the ceiling, which is undesirable from both a design and cost standpoint. Additionally, the number of inspection ports has increased in recent years due to the minimization of floor heights, especially in the attic space.

Therefore, the present invention aims to eliminate the need for dedicated inspection ports by making it possible to directly inspect equipment and equipment, and also to facilitate construction and inspection.

``Means for Solving Problems'' This invention consists of stacking an air supply cylinder that closes the upper end on the outer periphery of an exhaust cylinder that opens vertically, and providing an intake port at the lower end of the exhaust cylinder. has an air outlet at the bottom end,
In addition, an air inlet is provided at a proper location, and a damper equipped with an actuator for automatic temperature control is attached to the air inlet.

``Function'' It has the above configuration, and when used, it is installed and fixed in one of the squares of a lattice-like ceiling frame.
Connect the air supply duct to the air inlet. in this case,
The entire area under the attic is also used as part of the exhaust duct, and the exhaust duct in the attic is omitted.

The conditioned air supplied from the air conditioner enters the air supply cylinder from the air inlet through the air supply duct, and is supplied to the room, passage, etc. from the outlet. Furthermore, air from the room, passageway, etc. is sucked into the suction port, flows into the attic through the exhaust cylinder, and is returned to the air conditioner through the exhaust duct.

At this time, in the exhaust cylinder, the actuator works according to the temperature of the air flowing in from the room, passage, etc., and the damper is actuated by this to optimally adjust the flow rate of the supplied air, and the temperature environment of the room, passage, etc. is always kept constant.

Next, perform inspection directly from the air outlet and suction port.
