[Industrial applications]

  The present invention relates to a ceiling concealment type air purifier.

[0002]

[Prior art]

  In the individual distributed air conditioning system such as a ceiling cassette type air conditioner, ventilation is performed using a heat exchanger. In general, indoor air is purified by dilution by introducing outside air. It   Therefore, the conventional individual distributed air-conditioning system can sufficiently purify the indoor air. If you can not purify the indoor air, install an indoor exposed air purifier separately. There is a need.   However, installing a large air purifier creates a problem in terms of space. Jijiru   Therefore, a small air purifier of the electrostatic precipitator type is used relatively often.

[0003]

[Problems to be solved by the device]

However, this type of small air purifier has a problem that it has a small purification capacity and cannot treat odors and toxic gases (NO ₂ , SO ₂ , formaldehyde, etc.). Therefore, in order to purify the air in non-residential spaces such as offices and factories, there is no choice but to install a large-scale air purifier, and the fact is that it is rarely used in terms of space. The present invention has been devised in view of the above circumstances, and an object of the present invention is to have a large purification treatment capacity, can be installed without taking space in a room, and can also treat odors and toxic gases. It is to provide an excellent air purifier in terms of energy saving.

【Example】

  A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.   1 is a sectional plan view of an air purifier according to the present invention, FIG. 2 is a front view of the same, and FIG. The schematic side view of a mounting state is shown.   In the figure, 1 is an air purifier, and the air purifier 1 includes a ceiling 3 and a slab as shown in FIG. The air purifier 1 is installed in a space above the ceiling 3 defined by the slab 5 and the slab 5. It is fixed by an attached stay 7.   The air purifier 1 includes a substantially rectangular parallelepiped housing 9, and a left side surface 9 of the housing 9 An inlet 11 and an outlet 13 are opened at A, and an inlet 15 is provided at the right side surface 9B. And the exhaust port 17 is opened.   The inlet 11 and the outlet 13 are the inlet 3A and the outlet 3B provided on the ceiling 3. Are connected to each other by ducts 19, and the intake port 15 and the exhaust port 17 are connected to the supply / exhaust gallery. The ducts 21 are connected to each other.

[0006]   The inside of the housing 9 has a first wall extending in parallel with the left and right side surfaces 9A and 9B. Due to the part 23, the space on the left side is the air purification chamber 25, and the space on the right side is the heat exchanger. It is defined in chamber 27.   The air purification chamber 25 has an air passage 29 extending from the suction port 11 to the air outlet 13, The air passage 29 is a second wall portion that extends in parallel with the front and rear surfaces 9C and 9D of the housing 9. The first passage 29A from the suction port 11 toward the first wall portion 23 and the first passage It is partitioned into a second passage 29B extending from the wall portion 23 toward the outlet 13 and is divided into the first and second passages. The passages 29A and 29B are communicated with each other by the opening 31A at the end of the second wall portion 31, A damper 31B for adjusting the air volume is attached to A so that it can be opened and closed.

[0007]   Air flows from the inlet 11 to the outlet 13 in the first passage 29A and the second passage 29B. Fans 33 and 35 are attached so as to move, respectively. The openings 23A and 23 are provided in the portion facing the passage 29A and the portion facing the second passage 29B, respectively. B is formed, and dampers 23C and 23D for adjusting the air volume are provided in the openings 23A and 23B, respectively. Is attached so that it can be opened and closed.   A pre-filter 37 is attached to a portion of the first passage 29A near the suction port 11. In addition, an afterfill is provided in a portion of the second passage 29B near the outlet 13. A filter 39 and the after filter 39 and the fan 35. In between, medium performance filter 41, chemical adsorption filter 43, activated carbon filter 4 A unitized filter 47 consisting of 5 is attached.

[0008]   A heat exchanger 51 is disposed in the heat exchanger chamber 27, and the damper 23C is provided. A wall portion 53 is formed so as to partition the space facing the intake port 15 from the space facing the intake port 15, A wall separating the space facing the damper 23D from the space facing the exhaust port 17. The part 55 is formed.   Openings 53A and 55A are formed in the wall portions 53 and 55, respectively. , 55A are provided with dampers 53B, 55B that can be opened and closed, respectively.

[0009]   Next, the operation will be described.   First, the case where the dampers 53B and 55B of the heat exchanger chamber 27 are open will be described. Then, the rotation of the fans 33 and 35 causes the air in the room to move to the suction port 3A of the ceiling 3 and the duct. The first passage 29A enters from the inlet 19 and the suction port 11.   Then, in the first passage 29A, the dust is removed by passing through the pre-filter 37, A part of it goes through the opening 33A to the second passage 29B through the fan 33, and the remaining part From the opening 23A to the heat exchanger chamber 27.

Part of the air that has reached the heat exchanger chamber 27 is discharged from the exhaust port 17 through the heat exchanger 51 to the supply / exhaust gallery through the duct 21, and part of the air is taken in through the opening 53A. It reaches the space on the side of the port 15 and reaches the second air passage 29 through the heat exchanger 51 and the opening 23B together with the outside air from the intake port 15. Then, together with the air from the opening 31A, it passes through the fan 35, the filter 47 and the after filter 39. At this time, the medium-performance filter 41 removes dust, the chemical adsorption filter 43 removes toxic gases such as NO _X and formaldehyde, and odorous components, and the activated carbon filter 45 does not remove SO _{2 and} other chemical adsorption filters 43. Toxic gas and odorous components are removed, and dust is removed by the after filter. Then, the purified air is blown out into the room through the air outlet 13 and the duct 19 through the air outlet 3B of the ceiling 3.

[0011]   Also, adjust the opening / closing angle of the air volume adjusting dampers 23C, 23D, 31B. The air volume is adjusted by.   It is also possible to save energy by closing the dampers 53B and 55B during cooling and heating. Becomes   That is, if the dampers 53B and 55B are closed during cooling, the heat exchanger is opened from the opening 23A. The temperature of the room air that enters the chamber 27, passes through the heat exchanger 51, and is discharged from the exhaust port 17 From the intake port 15 through the heat exchanger 51 to the opening 23B and the second air passage 29B. The outside air introduced into the room can be cooled, and the In addition, it becomes possible to warm the outside air by the temperature of the room air and introduce it into the room.

[0012]   As described above, according to the present embodiment, since the ceiling concealment type air purifier 1 is used, the indoor space There is no pace problem, and a large dead space between the ceiling 3 and the slab 5 is used for large An air purifier 1 having a clean purification capacity can be obtained, and odors and toxic gases can also be removed. It is possible to leave.   Further, since the air purifier 1 is configured by using the heat exchanger 51, it is possible to save the time when cooling and heating. It is also possible to plan energy.   Furthermore, the air purifier 1 is connected to an already installed ceiling cassette type air conditioner. It is also possible to use.

[0013]

[Effect of device]

  As is clear from the above description, according to the present invention, the purification capacity is large and It can be installed without taking up space, can handle odors and toxic gases, and saves space. An air purifier that is also excellent in terms of energy can be obtained.
