Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a heat exchange unit of a separation type air conditioner arranged in a room called an outdoor shaft facing a pipe shaft of a housing complex or a condominium. .

(B) Conventional technology As a structural example of this type of heat exchange unit, Japanese Patent Application No.
There is a proposal in 63-88853.

This content is such that the suction port and the discharge port are arranged side by side on the front surface of the housing, and the heat exchanger and the cross flow fan are housed in the ventilation path leading to the suction port and the discharge port. is there.

Then, the rotation of the crossflow fan sucks air from the suction port on the front surface of the housing, and discharges the sucked air from the discharge port on the front surface.

Here, since the opening and the inside of the pipe shaft are narrow, a service valve is provided on the bottom surface of the heat exchange unit to secure a space below the heat exchange unit as a service space.

(C) Problems to be solved by the invention When the service valve is fixed to the bottom of the heat exchange unit in this way, the bottom of this unit cannot be placed directly on the floor, etc. I had to.

The present invention is intended to facilitate the handling during installation and transportation of a heat exchange unit having a service valve fixed to the bottom surface.

(D) Means for Solving the Problem In order to achieve this object, the present invention provides a base having a service valve protruding from the lower surface of the unit body and having a height dimension larger than the protruding dimension of the service valve on the lower surface. The leg and the lower attachment are detachably attachable.

(E) Action When the unit body is placed on the floor, a space is formed between the unit body and the floor by the legs.

Further, by fixing a small lower attachment to the lower surface of the main body, a service space is secured below the main body.

(F) Example In FIG. 1, 1 is an open corridor outside an apartment house (condominium), and 2 is a room facing this corridor (outdoor), which is called a pipe shaft. An electric meter, a gas meter, a gas pipe, a water pipe and the like (not shown) are housed in the pipe shaft 2. 3 is this pipe shaft 2
A service door that covers the lower opening 4 of the electric vehicle has a meter reading window 5 of an electric meter, a meter reading window 6 of a gas meter, and a ventilation port 7. In this way, the pipe shaft 2 and the open corridor (outdoor) 1 are not completely partitioned but are partitioned in an open state in which children cannot enter. Reference numeral 8 is an outdoor heat exchange unit (hereinafter referred to as “unit body”) of the separation type air conditioner, and 9 is a boiler, each of which has a rectangular parallelepiped shape and its front surface is flush with the wall surface 10 of the open corridor 1. It is incorporated in the pipe shaft 2 so that In this way, by making the front surface 11 of the unit body 8 and the boiler 9 flush with the wall surface 10 of the open corridor 1, there are no protrusions in the open corridor 1 to facilitate walking in the corridor.

FIG. 2 is a perspective view showing the mounting state of the unit main body 8. Reference numeral 12 is a mounting frame incorporated in the opening of the pipe shaft 2, and an upper mounting piece 13 is provided on the upper side and a lower mounting piece 14 is provided on the right and left sides (right side mounting section). Each piece is invisible because it is hidden by the unit body 8). Reference numeral 15 is a mounting plate that is mounted across the lower mounting pieces 14. Reference numeral 16 is an upper mounting tool for temporary fixing which is mounted on the upper surface of the unit main body 8 and has a dharma hole 17 formed therein. A screw 18 screwed into the upper mounting piece 12 is inserted into the dharma hole 17.

Reference numeral 19 is a valve arranged behind the lower surface 26 of the unit main body 8, and 20 is an inter-unit pipe extended from the room into the pipe shaft 2 through the through hole 21, and the connecting tool 22 of this pipe is connected to the valve 19. Be connected. Reference numeral 23 denotes a base leg that is attached to the front and rear of the lower surface 26 of the unit main body 8 when the unit main body 8 is shipped from the factory. The height dimension a of the base leg 23 is set to be larger than the height dimension of the valve 19. . Therefore, when the unit body 8 is placed on the floor or the open corridor 1 during transportation or before installation, the base leg 23 does not reach the floor and the valve 19 does not reach the floor, and the unit body 8 is placed on the floor or the like. Can be stably placed. When installing the unit main body 8, the base leg 23 is removed.

Reference numeral 24 is a lower mounting tool that is mounted when the unit body 8 is installed. The lower mounting tool 24 is bent in a substantially L shape and is a horizontal piece.
25 is fixed to the lower surface 26 of the unit body 8 and the vertical piece 27 is fixed to the mounting plate 15 by screws. Here, the dimension b between the mounting holes 28 of the lower mounting member 24, the dimension c between the mounting holes 29 of the leg pieces 23, and the dimension d between the screw holes (fixing portions) 30 of the unit body 8 are the same. . Therefore, the lower attachment 24 can be fixed to the position where the leg pieces 23 are removed from the lower surface 26 of the unit body 8. Further, the height dimension of the lower attachment 24 is set smaller than the height dimension a of the base leg 23.

Reference numeral 31 is a suction port of the unit main body 8, 32 is a discharge port, and a heat exchanger, a blower, a compressor and the like are housed inside the unit.

When installing such a unit main body 8 in the pipe shaft 2, first, the mounting plate 15 is fixed across the lower mounting pieces 14 of the pipe shaft 2. Then, the Daruma hole 17 of the upper mounting member 16 of the unit body 8 is locked to the screw 18 of the upper mounting piece 13.

As a result, the unit main body 8 is placed in the pipe shaft 2 in the state of air fishing. In such a state, the base leg 23 is removed from the lower surface of the unit body 8 (see solid line arrow in FIG. 2), and the lower mount
Attach 24 horizontal pieces 25 to this underside 26. Then, the vertical piece 27 of the lower attachment 24 is fixed to the attachment plate 25 with a screw, and the screw 18 locked in the dharma hole 17 is fixed. After fixing the unit main body 8 in this way, the connector 22 of the inter-unit pipe 20 is fixed to the service valve 19. At this time, since the height dimension of the lower fixture 24 is set smaller than the height dimension a of the leg piece 23, there is little possibility that the lower fixture 24 will interfere (interfere) when the service valve 19 is operated.
After the unit body 8 is thus installed in the pipe shaft, the service door 3 is closed.

(G) Effect of the Invention As described above, according to the present invention, the lower surface of the unit body on which the valve is provided has the leg piece having a height dimension larger than the protruding dimension of the valve. This unit can be stably placed on the floor during transportation and before installation.

Also, the base of the unit body and the fixture for installing the unit body are detachably attached to the lower surface of the unit body provided with the valve, so that the size of the fixture should be reduced. As a result, a large service space can be secured below the unit body, and the valve can be easily operated.
