BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filtering and air conditioning equipment in which an air filter and an air conditioner installed downstream thereof are directly connected.

[0002]

2. Description of the Related Art An air filter called an air filter (hereinafter referred to as a filter) and an air temperature controller called an air conditioner (hereinafter referred to as an air conditioner) are well known, and are also connected through a connecting casing. Filtration and air conditioning equipment in which both are connected in series to perform both filtration and air conditioning are also known, and are widely used in buildings, factories, hospitals and the like that require clean air.

The filtration air conditioning equipment in which the filter and the air conditioner are connected to each other is formed by connecting a connecting flange around the downstream side of the filter and a connecting flange around the upstream side of the air conditioner via a connecting member. However, when it is installed in a building, etc., it is necessary to store it in a partition wall or a duct, so the connecting flange cannot use an outer flange protruding outward, and an inner flange is used. .

Further, since the filter has a filter medium and its supporting member immediately upstream of the connecting flange, and the air conditioner has a heat exchange coil immediately downstream of the connecting flange, the inner flange for connection is directly bolted. Since it cannot be connected with a nut or the like, as shown in FIG. 4, the connection is made through a connecting casing 13 in order to secure a space for an operator to enter and work.

This connection casing 13 has a door on its side surface, and a worker has a depth of at least about 400 mm as a work space for entering the inside and connecting the front and rear filters A and B. Direction length) is required.

As described above, conventionally, in order to connect the filter and the air conditioner to constitute the filter air conditioning equipment, a large connecting part called a connecting casing that a person can put in is required, and the connecting casing is also required. No. 13 has a problem that it becomes a useless dead space after connection.

[0007]

SUMMARY OF THE INVENTION The present invention is intended to solve the above problems, and enables a filter and an air conditioner to be directly connected to each other without using a connection casing, and a connecting part. It is intended to provide a filter air-conditioning system which saves the cost and has no dead space between the filter and the air conditioner.

[0008]

The present invention provides means for solving the above-mentioned problems, and is an air conditioner B
The channel-shaped spacer 3 is connected to the upstream connection flange 10 of the filter via the flange gasket 2 by the first bolt / nut 11, and the downstream connection flange 1C of the filter A is also connected to the spacer 3 via the flange gasket 2. A filter air-conditioning facility is characterized in that the filter A and the air conditioner B are directly connected to each other by connecting them with a second bolt / nut 4.

[0009]

EXAMPLE FIG. 1 shows an exploded view of a joint portion between a filter A and an air conditioner B. In the figure, reference numeral 1 denotes a casing of a filter A, which has a rectangular frame body composed of an upstream flange 1A for connecting a duct (not shown), four side plates 1B, and a downstream flange 1C.

Reference numerals 2 and 2 denote flange gaskets, which are located between the downstream flange 1C of the filter A and the upstream flange 10 of the air conditioner B with the channel-shaped spacer 3 interposed therebetween.
It is inserted between and to perform air sealing.

The channel spacer 3 is connected to the upstream side flange 10 of the air conditioner B by a first bolt / nut 11 via a flange gasket 2 as shown in FIG. 2, and also as shown in FIG. It is adapted to be connected to the downstream side flange 1C of the filter A by a second bolt / nut 4 via a flange gasket 2. Note that, in FIG. 1, the positions of the bolts and nuts 11 are shown in a slightly downward position to facilitate understanding.

In the first bolt / nut 11, the bolt 11a is fixed to the flange 10 side of the air conditioner B, and the nut 11b is tightened from the spacer 3 side, while the second bolt / nut 4 is the spacer. Nut 4b on 3 side
(Or bolt 4a) is fixed and the flange 1C of the filter A is fixed.
It is preferable to tighten the bolt 4a (or the nut 4b) with the wrench 5 from the side.

In the figure, 6 is a filter medium, 7 is a filter medium backing wire mesh, 8 is a pressure medium pressure loss receiving support, 9 is a filter medium peripheral sealing plate, and 12 is a heat exchange pipe of an air conditioner.

[0014]

The procedure for connecting the filter A and the air conditioner B will be described with reference to FIGS.

First, as shown in FIG. 2, the spacer 3 is attached to the upstream side flange 10 of the air conditioner B via the flange gasket 2. At this stage, since the space on the upstream side of the air conditioner B is wide, the bolts 11a fixed to the flange 10 are inserted through the mounting holes of the gasket 2 and the spacer 3, and the nuts 11b are tightened from the channel-shaped spacer 3 side. Attaching work can be performed easily.

Next, as shown in FIG. 3, the spacer 3 attached to the upstream connecting flange 10 of the air conditioner B.
Then, the downstream side flange 1C of the filter A is connected via the flange gasket 2. At this stage, the space between the upstream side of the air conditioner B and the downstream side of the filter A is closed so that a tool cannot be inserted, but the nut 4b fixed to the spacer 3 is bolted from the back side of the flange 1C. 4a can be screwed in and a tightening operation can be performed with a wrench 5 as shown in FIG. The same effect can be obtained by reversing the positional relationship between the bolt 4a and the nut 4b.

[0017]

According to the present invention, the channel-shaped spacer 3 is attached to the connection flange 10 on the upstream side of the air conditioner B via the flange gasket 2 and the first bolt / nut 11 (11a,
11b), and the connecting flange 1 on the downstream side of the filter A is also connected to the spacer 3 via the flange gasket 2.
By connecting C with the second bolt / nut 4 (4a, 4b), it is possible to directly connect the filter A and the air conditioner B without using the connection casing 13 that has been conventionally required. Therefore, it is possible to save the connecting parts and provide the filter air-conditioning equipment with no dead space between the filter and the air conditioner.
