Description

The present invention relates to a heat exchange unit containing a compressor, a heat exchanger, a blower and the like.

(B) Conventional technology Conventionally, an example of the structure of this type of heat exchange unit is disclosed in Japanese Utility Model Publication No. 60-39722.

According to this content, the exterior body of the heat exchange unit is provided with a bottom plate, a peripheral panel attached to the bottom plate and serving as the upper surface and left and right side surfaces of the unit, and a front panel and a rear panel opening of the peripheral panel. The front panel was provided with a discharge port, the peripheral panel was provided with a suction port, and the rear panel was provided with a blower. In addition, compressors, heat exchangers and electrical components were arranged on the bottom plate. The rotation of the blower sucks air from the inlet of the peripheral panel, and heat-exchanges the sucked air with the refrigerant flowing in the heat exchanger, and then blows out the heat-exchanged air from the outlet of the front panel. I was trying to make it.

(C) Problems to be Solved by the Invention As described above, in the heat exchange unit, the blower is attached to the rear panel. This blower is connected to electrical components mounted on the bottom plate by lead wires or the like. Therefore, when the rear panel is removed to perform a service check of the compressor or the like, care must be taken so as not to break the lead wire, and it is difficult to perform a service check.

SUMMARY OF THE INVENTION An object of the present invention is to facilitate service inspection of components built in a heat exchange unit.

(D) Means for Solving the Problems In order to achieve this object, the present invention arranges a blower and a compressor in a front-rear direction within a housing of the unit, and attaches a front opening of the housing to a detachable front panel. Thus, the rear openings are each closed with a rear panel.

Further, the inside of the housing is divided into front and rear by a casing of the blower, and a heat exchanger and a blower are arranged in a front chamber closed by a front panel, and a compressor is arranged in a rear chamber closed by a rear panel.

(E) Operation The blower and heat converter can be inspected by removing the front panel of the heat exchange unit, and the compressor can be inspected by removing the rear panel. Further, since the inside of the housing is partitioned into a front chamber and a rear chamber by the casing of the blower, a dedicated partition plate for partitioning the two chambers is not required.

(F) Embodiment The drawings show an outdoor heat exchange unit of the separation type air conditioner of the present invention, and this heat exchange unit is arranged on a vip shaft of a high-rise building (house). This vip shaft is the air (room) through which gas pipes and the like pass through each floor of the high-rise building. This space faces the corridor of the high-rise building and is open to the extent that children cannot enter by doors and the like. Partitioned from the outside in a state.

In FIG. 1, the heat exchange unit 1 has a housing composed of a bottom plate 2, a top plate and a cabinet 3 serving as left and right side plates, and a front panel 4 is provided at a front portion of the cabinet 3 and a rear panel is provided at a rear portion. 5 are detachably attached. A fixing piece 7 is provided on the upper plate 6 and the bottom plate 2. Reference numeral 8 denotes a mounting frame installed inside the vip shaft and facing the corridor. A mounting piece 11 is formed on the upper piece 9 and the left and right pieces 10 of the frame 8. And this mounting frame 8
Then, the heat exchanging unit 1 is inserted into the unit, the fixing piece 7 of the unit 1 is brought into contact with the mounting piece 11 of the mounting frame 8, and the fixing piece 7 is mounted on the mounting piece 11 with a screw. When the heat exchange unit 1 is mounted on the mounting frame 8 in this manner, the front panel 4 of the heat exchange unit 1 faces the corridor of the high-rise building. Reference numeral 12 denotes a service valve attached to the bottom plate 2 of the heat exchange unit 1, and an interunit piping 13 is connected as shown in FIG. In FIG. 2, reference numeral 14 denotes an inter-unit cable extending from the bottom plate 2 and extends rearward along the bottom plate 2 together with the inter-unit piping 13.

FIGS. 3 and 4 show the structure of this heat exchange unit. Reference numeral 15 denotes a heat exchanger which is set up obliquely with respect to the depth direction of the bottom plate 2 (the direction of the solid arrow A). 16 is this bottom plate 2
An electric box arranged near the front edge 17 of the electric motor is a fan motor arranged behind the electric box. A cross-flow fan 20 is mounted on a rotating shaft 19 of the motor.
The fan 20 and the motor 18 constitute a blower 43. Reference numeral 21 denotes a compressor disposed behind the fan 20, which is located near the rear edge 22 of the bottom plate 2. Reference numeral 23 denotes a casing of the cross flow fan 20, which is disposed between the fan 20 and the compressor 21. Reference numeral 24 denotes a nozzle plate, which is attached to a front edge 25 of the heat exchanger 15. In this manner, the cross flow fan 20 and the compressor 21 are arranged on the bottom plate 2 in the front-rear direction, and such a refrigerating device is covered by a cabinet, and the upper part and both right and left sides thereof are covered.

The rear panel 5 is provided in the rear opening 41 of the cabinet 6.
The front panels 4 are attached to the front openings 40, respectively. By removing the front panel 4 and the rear panel 5, the front opening 40 and the rear opening 41 of the cabinet 6 are opened. Therefore, by removing the front panel 4, the cross flow fan
The service check of the compressor 20 and the heat exchanger 25 can be performed, and the service check of the compressor 21 can be performed by removing the rear panel 5.

A ventilation grill 29 is provided on the front panel 4 described above, and this grill 29 is divided by a vertical bar 30 into a left suction portion 31 and a right discharge portion 32. And cross flow fan 20
, The air flows as shown by the solid arrow in FIG. This cross flow fan 20 and front panel 28
The relationship with the ventilation grill 29 is as shown in FIG. That is, the blade 33 of the cross flow fan 20 is inclined obliquely upward with respect to the front panel 4. Further, the ventilation changing blades 34 of the ventilation grill 29 are inclined upward.
Therefore, the wind discharged from the cross flow fan 20 changes the direction and velocity distribution of the wind discharged from the ventilation grill 29 as shown by the solid line in FIG. 5 due to the inclination of the wind direction changing blades 34 of the ventilation grill 29. Even if the heat exchange unit 1 is installed so that the grill 29 is positioned at the level of the face of the person, the amount of air hitting the face of the person is reduced.

(G) Effect of the Invention As described above, the present invention arranges the blower and the compressor in the front-rear direction in the housing, and has a detachable front panel provided with a ventilation opening at the front opening of the housing. In addition, since the rear opening of the housing is closed with a detachable rear panel, the blower can be seen by removing the front panel, and the compressor can be seen by removing the rear panel. Therefore, if both panels are removed as required, service inspection in the unit can be easily performed. Further, since the inside of this unit is divided into front and rear by the casing of the blower, the structure can be simplified without using a dedicated partition plate, and the number of parts can be reduced.
