JP2551426Y2 - Floor-distributed air outlet with ceiling outlet - Google Patents

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to improvement of air-conditioning equipment with a floor-blowing ceiling.

[Conventional technology]

In general air conditioning for buildings, the most common method is to blow out conditioned air from the ceiling surface and suck it in from the ceiling surface. According to this,
The space above the ceiling can be effectively used as a duct facility space, and in some cases a package type air conditioner or fan coil unit can be stored behind the ceiling, which is advantageous in terms of effective use of space and aesthetics. The occurrence of uneven temperature is inevitable. For this reason, the floor blowing method has recently begun to be adopted, albeit only slightly.

[Problems to be solved by the invention]

In the conventional floor blowing method, air at a set temperature is blown from the floor through a pre-positioned outlet.
On the same floor, it was virtually impossible to start and stop air supply and set the temperature for each zone. Also, the location of the outlet could not be changed arbitrarily according to the indoor use conditions and the arrangement of the equipment and the desk. An air-conditioning floor structure proposed in Japanese Patent Application Laid-Open No. 62-169955 is known as an example of constructing a duct capable of supplying and exhausting air with a three-dimensional floor surface. There is a problem that the floor structure proposed in this gazette cannot cope with floor wiring for OA equipment accompanying new office equipment. Also, the floor structure uses the building floor as the bottom of the duct,
Heat loss from the building floor and dew condensation on the floor surface are likely to cause problems.

The present invention is intended to solve such a problem.

[Means to solve the problem]

In the present invention, the conditioned air treated by the air conditioner is blown upward into the room from the air outlet on the floor, and the room air is sucked into the space above the ceiling from the air inlet on the ceiling, and this air is circulated to the air conditioner as return air. In the air-conditioning equipment of the floor blow-off ceiling suction type, the floor of the zone to be air-conditioned is floated off the skeleton floor, and the space under the floor between the floating floor and the skeleton floor has sufficient capacity to handle the load of each air-conditioning zone. An air conditioner is arranged in each zone, and a blow-out floor unit having an air blow-out surface and a blind floor unit having almost the same shape as this are installed at the same height level so that they can be removed. The floor of the zone to be air-conditioned is formed, and a floating floor is formed by combining the blow-out floor unit and the blind floor material unit with air outlets distributed on the floor, and air supply of the air conditioner is supplied to the blow-out floor unit. In the underfloor space And wherein the guiding through the block ducts location the flexible duct or the bottom is arranged floated from precursor bed.

[Action]

According to the air conditioner of the present invention, the room temperature distribution is made uniform because air is supplied into the room from the floor surface. Almost independent air conditioning can be performed for each zone, and the set temperature can be changed for each zone, and the air conditioner can be started and stopped freely. In particular, since the position of the air outlet on the floor can be freely changed, it is possible to freely respond to changes in the indoor layout such as OA equipment installation and desk layout, and to perform the desired air conditioning with energy saving.
In addition, since it is a floating floor, wiring under the floor can be performed freely, and since the air conditioner is installed under the floor, maintenance is easy and it is safe against drain water leakage, heat loss from the building floor and heat loss. Dew condensation on the floor can also be prevented.

The arrangement of the outlet floor unit 8 and the flexible duct 17 can be arbitrarily provided as shown in FIG.

On the other hand, the air in the room enters a space above the ceiling 12 through a suction port 11 provided in the ceiling 3, and the air in the space above the ceiling 12 is taken into the air conditioner 6 through the vertical duct 13 as return air. By providing the exhaust port 14 and the outside air inlet 15 at appropriate points in the air circulation path, ventilation can be performed. When an air heat source heat pump unit is used as the air conditioner 6, the outdoor unit 16 is installed at an appropriate place as shown in FIG.

FIGS. 3 and 4 are substantially the same as the examples of FIGS. 1 and 2 except that the conditioned air processed by the air conditioner 6 is sent through the block duct 20. 1 shows an embodiment of an air conditioner according to the present invention. The block duct 20 itself is a constituent member of the floating floor 4, and connects a unit block formed of a hollow cube or a rectangular parallelepiped from the skeleton floor 1 with the support rod 21. At that time,
The blow-out floor unit 8a is also formed of a hollow cube or a rectangular parallelepiped like the duct block.
