Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a membrane-covered ceiling panel and a ceiling air conditioner that are applied to buildings such as ordinary houses, apartment houses, and buildings.
[0002]
[Background Art and Problems to be Solved by the Invention]
As an air conditioner in a house, a wall-mounted air conditioner is generally installed, and a ceiling built-in air conditioner is also used in some cases.
However, these air conditioners are all convection types in which the temperature-adjusted air is simply circulated in the indoor space, resulting in uneven temperature distribution in the room and uncomfortable feeling due to local winds. There are many cases.
In order to solve such problems, the present applicant partitions the indoor space and the ceiling space with a breathable ceiling membrane, and supplies fresh air or blows out temperature-controlled air from the back of the ceiling through the ceiling membrane. Tried what to do. The ceiling membrane may be directly stretched on a ceiling base such as a field edge, but if it is configured as a ceiling panel with a ceiling membrane stretched on a panel frame, it is convenient for construction and maintenance. When the ceiling membrane is stretched on the panel frame, it should be moistened to prevent wrinkles and slack.
However, even if the ceiling membrane is stretched as described above, it is expected that slack and wrinkles will occur over the years and the appearance of the ceiling will deteriorate.
[0003]
The present invention solves the above-mentioned problems, and uses a membrane-clad ceiling panel that allows the ceiling membrane not to sag for many years, or to easily eliminate sag even if sag occurs, and the ceiling panel. It aims at providing the ceiling air conditioner which can perform comfortable air conditioning.
[0004]
[Means for Solving the Problems]
The membrane-clad ceiling panel of the present invention is obtained by stretching a breathable ceiling membrane using a shape memory material such as a shape memory resin or a shape memory alloy on the outer peripheral frame. This membrane-clad ceiling panel is used in a ceiling air conditioner that allows air to enter and exit between the ceiling back space and the indoor space via the breathable ceiling membrane.
Since the shape memory material is used as the material of the ceiling membrane, the ceiling membrane is always kept in tension without causing slack due to secular change, and a good appearance can be maintained. Alternatively, even if the ceiling membrane is slack, it can be stretched to the original state by performing a process such as heating.
In the membrane-clad ceiling panel having the above-described configuration, the ceiling membrane may be made of a material that can transmit heat and / or water vapor in addition to air.
By using such a material, it is possible to control the movement of heat and water vapor, or the amount of movement, as well as the entry and exit of air, between the ceiling back space and the indoor space partitioned through the membrane-coated ceiling panel.
[0005]
In the ceiling air conditioner of the present invention, the membrane-covered ceiling panel is arranged in parallel to partition the indoor space and the ceiling back space, and an air outlet is provided in the ceiling back space.
According to this structure, the air blown out from the air outlet goes to the ceiling back space, or this air is blown into the room through the ceiling membrane. At this time, since the blowing speed is controlled by the ceiling membrane and blown out from the range of the ceiling surface, the blowing of air from the ceiling back space to the indoor space is slow, and the indoor space is not exposed to the wind. Comfortable air conditioning is possible.
The air blown out from the air outlet may be air whose temperature is adjusted by an air conditioner, or may be fresh air simply supplied for ventilation. When the temperature-adjusted air is blown out, the temperature-adjusted air is distributed not only in the indoor space but also in the ceiling space, so that comfortable air conditioning without temperature unevenness can be performed. The space behind the ceiling may be an undivided space in which the air blown out from the air outlet naturally flows, or a space in which the air blows out forcibly through a predetermined path provided with a meandering partition. It is also good. This ceiling air conditioner is more effective in the case of a highly insulated and airtight building.
In the ceiling air conditioner, in the ceiling space, a plurality of functional chambers whose bottom surfaces are opened are provided, each functional chamber contains at least one of a dehumidifying device, a cooling / heating device, and an air purifier, and the air outlet is connected to the air outlet. Each functional chamber may be opened, and the lower surface opening of each functional chamber may be covered with the membrane-clad ceiling panel.
According to this configuration, dehumidification, air conditioning, and air cleaning can be selectively performed for each indoor location.
In the ceiling air conditioner, an air suction port may be opened in any of the functional chambers.
By providing the suction port in this way, air can be circulated between the plurality of functional chambers, and the air circulation flow path can be freely selected and set.

The outer peripheral frame 8 is formed as a metal frame such as light iron or aluminum having a groove-shaped cross section to be an engaging groove 8a on the outer periphery, or a resin frame. The ceiling membrane 4 is preferably made of a material having a selective permeation function that allows heat and water vapor to pass with an appropriate permeability in addition to air.
When a shape memory resin is used for the ceiling membrane 4, it may be a cloth woven with a thread made of the resin fiber, or a cloth woven with the resin as a thread.
When using a shape memory alloy, for example, a cloth woven with a TiNi shape memory alloy formed into a coil shape, or a TiNi shape memory alloy formed into a coil shape into a normal cloth, and the shape recovery temperature of the shape memory alloy Is set to a high temperature, for example, about 30 °.
[0007]
A plurality of the membrane-clad ceiling panels 9 are arranged side by side by being supported by the lifting tool 10 in the ceiling air conditioner 5 of FIG. 2A, and the ceiling membrane 4 of the ceiling panel 9 allows the ceiling back of the living space 1 to be installed. The space 2 and the indoor space 3 are partitioned. The living space 1 represents a room provided in the building B, and is partitioned from the adjacent room by a wall 40 to the back of the ceiling. A plurality of air conditioning ducts 6 are piped in the ceiling back space 2, and the outlet 6 a is opened in the ceiling back space 2. The air conditioning duct 6 is connected to an air conditioner 7 installed outside the living space 1. For example, the air conditioner 7 branches into a large number of rooms and supplies temperature-adjusted air, and a peat pump type or the like is used.
[0008]
As shown in FIG. 2 (B), the lifting tool 10 includes a suspension bolt 12 suspended by a height adjustment nut 13 on a lower flange 11a of an upper floor beam 11 made of H-shaped steel, and a bottom of the suspension bolt 12. It consists of a panel locking bar 14 having an inverted U-shaped cross section that is locked to the temporal region.

Reference numeral 16 denotes a floor panel.
[0009]
The operation of the ceiling air conditioner 5 having the above configuration will be described.
Temperature-adjusted air obtained by heating and cooling by the air conditioner 7, that is, cooling and warming air, is blown out from the air outlet 6 a of the air conditioning duct 6 and reaches the entire ceiling space 2. In parallel with this, air is transmitted between the ceiling space 2 and the indoor space 3 through the ceiling membrane 4 having ventilation resistance, which is induced by forced air movement in the ceiling space 2. Is called. Thereby, the blowing of cool / warm air from the ceiling back space 2 to the indoor space 3 is performed gently. For this reason, the indoor space 3 is comfortably ventilated and uniformly cooled / heated without locally cooling / heating. The air conditioning duct 6 may be connected to a fan or the like that simply ventilates instead of connecting to the air conditioner 7.
This ceiling air conditioner covers the ceiling with a ceiling membrane 4 having a selective transmission function capable of controlling ventilation, moisture transmission, radiation (radiation), etc., so that the ceiling pocket portion, that is, the entire ceiling space 2 is a kind. The chamber (partition space) structure is used to create a breathing action of air between the chamber and the indoor space 3 to realize non-aggressive ventilation. Here, “non-aggressive” refers to creating a base environment in which ordinary residents in the indoor space 3 can spend without being aware of the indoor environment. If you feel uncomfortable, you can adjust it according to your comfort zone.
[0010]
The ceiling membrane 4 of the membrane-covered ceiling panel 9 becomes loose with the passage of time due to its own weight and material deterioration, but when the room temperature exceeds the shape recovery temperature (for example, about 30 °) of the shape memory alloy in summer. The ceiling membrane 4 is restored to its original tension state. Therefore, the slack of the ceiling membrane 4 does not proceed due to secular change, and the ceiling surface can be maintained with a good appearance forever. In addition, when the air conditioning is set to the heating mode in winter, the ceiling membrane 4 is also used when the temperature of the warm air that passes through the ceiling membrane 4 from the ceiling back space 2 and blows out to the indoor space 3 exceeds the shape recovery temperature. The original tension is restored.
[0011]
In the ceiling air conditioner 5, since the membrane-covered ceiling panel 9 is supported by being engaged with the suspension tool 10, it is easily constructed in a state where the ceiling back space 2 and the indoor space 3 are partitioned by the ceiling membrane 4. The maintenance of the air conditioning duct 6 in the ceiling space 2 can be easily performed.
[0012]

In the ceiling air conditioner 15, as shown in FIG. 3A, a plurality of functional chambers 21 whose bottom surfaces are opened are provided in the ceiling back space 2. The air conditioning duct 6 is divided into an air supply duct and an exhaust duct, and is piped on an upper floor beam 11 made of H-shaped steel. The outlet 6a branched from the air supply air conditioning duct 6A is opened to some selected functional chambers 21A, and the suction port 6b branched from the exhaust air conditioning duct 6B is opened to another partial functional chamber 21B. It is.
[0013]
Each of the functional chambers 21, 21A, 21B is supported by a support bar 23 spanned on the upper floor beam 11 via a suspension bolt 22, and the lower surface opening of the functional chamber 21 is formed by the membrane-clad ceiling panel 9. Covered. That is, as shown in FIG. 3B, the suspension bolt 22 is locked to the support bar 23 by the height adjusting nut 13, and a chamber support bar 33 and an inverted U-shaped cross section are formed on the lower head of the suspension bolt 22. And the opening edges of the functional chambers 21, 21 </ b> A, 21 </ b> B are fixed to the chamber support bar 33. In addition, the engagement groove 8a of the outer peripheral frame 8 is engaged with the panel locking bar 14 as in the case of FIG. 2B, and the lower surface openings of the functional chambers 21, 21A, 21B are membrane-coated ceiling panels. 9 is covered. Thereby, the ceiling back space 2 and the indoor space 3 are partitioned by the ceiling film 4. Each functional chamber 21, 21A, 21B accommodates at least one of functional units 26 such as a dehumidifying device, a cooling / heating device, and an air purifier.

4A and 4B show a longitudinal sectional view and a bottom view of a functional chamber 21 in which a cooling / heating device is accommodated as the functional unit 26. FIG. In this figure, the membrane-covered ceiling panel 9 is omitted. In this case, a ceramic heater is used as the air conditioner. This ceramic heater is formed by extruding a conductive ceramic material into a mesh shape, and the heating temperature can be variably set by voltage control. In the functional chamber 21A where the air outlet duct 6a of the air supply air-conditioning duct 6A is opened, the air passing through the gap of the ceramic heater mesh is heated and becomes warm air from the lower surface opening of the functional chamber 21A. The air is gently blown into the indoor space 2 through
[0015]
In the case of this ceiling air conditioner 15, air blown into the functional chamber 21 from the air outlet 6a of the air supply air conditioning duct 6A is heated by a cooling / heating device accommodated as a functional unit 26 in the functional chamber 21A. The heated warm air is gently blown out from the functional chamber 21A to the indoor space 3 through the membrane-coated ceiling panel 9. Further, since the air in the indoor space 3 is exhausted from the other functional chamber 21B through the suction port 6b of the air conditioning duct 6B, warm air circulates in the indoor space 3 and ventilation is performed.
