2. Description of the Related Art A conventional direct expansion multi-air conditioning system has one
Multiple outdoor units are connected to the outdoor unit with refrigerant pipes to perform cooling and heating, and outside air treatment, that is, introduction of outside air, dust removal of the outside air, heat treatment, heat recovery and humidification, is performed on the ceiling pipe connected to the same refrigerant pipe. It was carried out with a built-in type outside air treatment device. Figure 8
9 and 9 are diagrams of a conventional direct expansion multi-air conditioning system.
Reference numeral 1 is an outdoor unit installed on the roof of a building or on a tower, which is composed of a compressor, a four-way valve, a condenser, a refrigerant control opening (not shown), etc., and 2 is an evaporator, a throttle device (not shown), etc. The indoor unit is constructed and installed behind the indoor ceiling, and is connected to the outdoor unit 1 through the pipe shaft 4 by the refrigerant pipe 3. The outdoor air processing device 61 is also connected to the outdoor unit 1 through the refrigerant pipe 3, is installed in the indoor ceiling, and is configured as shown in FIG. That is, 7 is an outdoor air suction port, 8 is a first filter for removing dust contained in outdoor air, and a high performance filter is used. Reference numeral 9 is a total heat exchanger unit, 10a is a blower for sucking in and discharging outdoor air into the room, 11 is a heat exchanger connected to the outdoor unit 1 through the refrigerant pipe 3, and evaporates via the throttling mechanism 11a. The function as a heater can be generated and the heat as a condenser can be released, and the function as a heater can be generated. 12 is a humidifier for humidifying the air passing through the condenser 11 during heating, 13
Is an outdoor air outlet for discharging the treated outside air into the room, and the intake path A is configured from the above. Reference numeral 14 is an indoor air suction port, and 15 is a second filter for removing dust in the indoor air, which is a medium performance filter.
Reference numeral 9 is a total heat exchanger unit, 10b is a blower for sucking indoor air out of the room, 16 is an indoor air outlet, and an exhaust path B is configured from the above, and the total heat exchanger unit 9 is , Heat exchange is performed between the air flowing through the intake passage A and the air flowing through the exhaust passage B. Reference numeral 17 denotes the outdoor air outlet 13 of the outside air treatment device 6.
The indoor unit 2 at the branch duct 17a with the air supply duct connected to
It is connected to the. An air duct 18 is connected to the indoor air intake port 14 of the outside air processing device 61 and is connected to the indoor air intake box 19. The outdoor air intake port 7 and the indoor air outlet port 16 of the outdoor air treatment device 61 are communicated with the outdoor air by penetrating the outer wall 22 by the intake duct 20 and the exhaust duct 21.
Reference numeral 23 is a ceiling material, and 24 is an inspection port provided on the ceiling material 23.

Next, the operation will be described. Outside air is sucked into the outside air processing device 61 through the outdoor air suction port 7, dust is removed by the high-performance filter 8, and flows into the total heat exchange unit 9.
On the other hand, the indoor air is sucked from the indoor air suction box 19 and passes through the recirculation air duct 18 to be sucked from the indoor air suction port 14 to the outside air processing device 61. Then, dust is removed by the medium-performance filter 15 and flows into the total heat exchanger unit 9, where the outdoor air and the indoor air are heat-exchanged, and the indoor air passes through the indoor air outlet 16 and the exhaust duct 21 by the blower 10b. It is released to the outside of the outer wall 22. Further, the outdoor air is cooled (heated during heating) by the evaporator (condenser in the case of heating) by the blower 10a,
Outdoor air outlet 13, air supply duct 17, and branch duct 17a
And is discharged to the primary side of the evaporator (condenser during heating) of the indoor unit 2. It goes without saying that the air humidified by the humidifier 12 is released during heating. On the other hand, the indoor unit 2 has a built-in high-performance filter 8 at the same time as the cooling or heating operation.
At the same time, the dust removal operation of the indoor air is also performed, and the outdoor air processed by the outdoor air processing device is simultaneously discharged into the room from the outlet of the indoor unit 2 to totally air-condition the room.

[0004]

Conventionally, the direct expansion multi-air conditioning system can realize the total air conditioning as described above, but the outside air treatment device having many functional parts that require regular maintenance is a ceiling-embedded type. Yes Due to the layout of functional parts, multiple inspection openings were required, and there were problems in maintenance and interior design. Therefore, a floor-standing type outside air treatment device was developed, but there were problems such as poor maintenance workability of a blower for heavy objects.

The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to obtain a floor-standing type outside air treatment apparatus having good maintainability.

[0006]

A floor-standing type outside air treatment apparatus according to the present invention is adapted to be fitted and detachably held by a mounting member provided on a blower and a supporting member provided on a top plate of a main body frame. .

[0007]

In the floor-standing type outside air treatment apparatus according to the present invention, the blower is provided with the mounting member and fitted with the support member provided on the top plate of the main body frame, so that the blower can be attached and detached while sliding.

[0008]

EXAMPLES Example 1. An embodiment of the present invention will be described below with reference to the drawings. Figure 1
In FIG. 2, reference numeral 2 is an indoor unit incorporating the high-performance filter 8, and 62 is a floor-standing type outside air treatment apparatus of the present invention installed in the pipe shaft cover 5, which is constructed as shown in FIG. That is, 7 to 16 are the same as those of the conventional outside air treatment apparatus shown in FIG. 10, and 27 is a table having a floor fixing hole 27a.
25 and 26 are collective intake ducts and collective exhaust ducts installed in the ceiling above the corridor, which penetrate the side wall of the building and communicate with the outside air via a weather cover (not shown), etc., and are installed on each floor of the building. Has been done. 4 is a waist enlarged view showing a mounting structure of a blower of the floor-standing type outside air treatment apparatus shown in FIG.
FIG. 5 is a perspective view showing a mounting structure of the blower. In FIG. 4, the mounting member 10d of the blower 10b has a substantially U-shaped cross section having a hypotenuse forming an angle θ ₁ with the horizontal plane, and the supporting member 6b has a slope forming an angle θ ₂ with the horizontal plane. Is attached to the top plate. This mounting structure is for blower 10a
The same applies to the mounting member 10c and the supporting member 6a.
It is composed of.

Next, the operation will be described. Outside air is sucked into the floor-standing type outside air treatment device 62 through the intake duct 20 and the outdoor air suction port 7 through the collective intake duct 25. In addition, the room air is sucked from the room air suction port 14 to the floor-standing type outside air treatment device 62 through the room air suction box 19 and the air circulation duct 18, and the heat is recovered by the total heat exchanger unit 9, and the room air outlet is formed. 16. Exhaust duct 21 discharges outside the building through collective exhaust duct 26. Other functions are similar to those of the conventional direct expansion multi air conditioning system. Next, at the time of maintenance of the floor-standing type outside air treatment device, open the inspection panel provided on the side wall of the corridor and remove the side panel (not shown) of the floor-standing type outside air treatment device 62. ,humidifier
12. Blowers 10a and 10b are possible from the corridor without using a stepladder. Especially for the blowers 10a and 10b, mounting screws are shown in FIG.
When 28 is loosened, the state shown in FIG. 6 is obtained, and it can be slid and removed as shown in FIG. That is, it is not necessary to work while supporting the blower, which is a heavy object, when attaching and detaching.
