Abstract

PURPOSE:To suspend a heat exchanger unit from a ceiling by a method wherein the inside of a cabinet of the heat exchanger unit is divided into a machine room at one end, a heat exchanger compartment in the middle and a heating compartment at the other end, and a horizontal type compressor is installed in the machine room, a heat exchanger and a fan in the heat exchanger compartment, and a heater for heating medium in the heating compartment. CONSTITUTION:Because the heat exchanger compartment 20 being in the middle, a heating compartment 21 is arranged on the left side and a machine room on the right side, the position of the gravity center of a heat exchanger unit 2 is located at nearly the middle of the unit 2, so that the unit is easily kept horizontal without a tilt when the unit is raised with hands held both right and left sides of the unit. As for a horizontal type rotary compressor 29 employed, the vibration due to rotation of a rotor (operation of the compressor) is larger in the vertical direction than in the horizontal direction because a rotating shaft of a rotor is horizontally laid. However, in this heat exchanger unit 2, rather heavy equipment such as a boiler 34, pump 35 and others are arranged on the opposite side of the machine room 19 in which the compressor is installed, so that the vibration is diminished by the boiler 34, the pump 35 and others even though the machine room is forced to be vibrated by the operation of the compressor 29.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a heat exchange unit that combines a heat medium heater with an outdoor unit of a separate air conditioner.

(B) Prior Art Conventionally, an example of the structure of this type of heat exchange unit has been disclosed in Japanese Utility Model Publication No. 60-38118.

According to this content, a heating unit incorporating a heater is combined on the side of a rectangular parallelepiped-shaped outdoor unit.

(c) Problems to be solved by the invention As described above, when a heating unit is combined on the side of an outdoor unit, the size of this heat exchange unit increases as a whole, and when this heat exchange unit is installed on the floor. However, the present invention has the problem that the space required for the heat exchange unit becomes large.
The purpose is to avoid providing installation space for the heat exchange unit on the floor.

(d) Means for Solving the Problems In order to achieve this object, the present invention divides the inside of the casing of the heat exchange unit into a machine room on one end side, a heat exchange room on the center side, and a heating chamber on the other end side. A horizontal compressor is installed in the machine room.
A heat exchanger and a blower are disposed in the heat exchange chamber, and a heat medium heater is disposed in the heating chamber.

(E) By arranging the horizontal compressor in the working machine room, the height of the heat exchange unit can be kept low. In addition, since the machine room where the compressor is placed on one side of the heat exchange room and the heating room where the heat medium heater is placed on the other side, the center of gravity of this heat exchange unit is Located approximately in the center,
This unit becomes difficult to tilt when lifted and installed on the ceiling.

(F) Embodiment The drawings show an embodiment. In FIG. 4, 1 is a balcony of an apartment or the like, and 2 is a heat exchange unit of a separate air conditioner attached to the ceiling of the balcony. This heat exchange unit 2 and an indoor unit (not shown) in the room 3 are connected by a refrigerant pipe and a hot water pipe (described later). A descending wall 5 is provided on the ceiling 4 of this balcony 1.

The upper plate 6 of this heat exchange unit 2 is provided with a suction port, the lower plate 7 is provided with a discharge port covered with a discharge grille 8 approximately on the left and right sides, and the front plate 9 is provided with an exhaust pipe 10. There is. When the heat exchange unit 2 is operated, the outdoor air flows as indicated by the solid arrow.

FIG. 3 is a perspective view of this outdoor unit 2, and its exterior body includes an upper plate 6 on which the fixture 11 is arranged, a rear plate 12, left and right side plates 13, 14, a front plate 9, and a lower plate 7. It is composed of a cabinet 15 in the form of an abbreviated character. 16 is a piping cover attached to this right side plate 14. After installing this outdoor unit 2 on the ceiling 4, the piping cover 16
By removing only the refrigerant pipe and hot water pipe, you can connect the refrigerant pipe and hot water pipe. On the other hand, the cabinet 15, left and right side panels 13.
14 can be removed for service inspection of the heat exchange unit 2, if necessary.

FIG. 1 shows the heat exchange unit 2 with the front plate 9 of the cabinet 15 cut away, and FIG. 2 shows the heat exchange unit 2 with the right side plate 14 removed. Inside this housing are two vertically extending partition plates 17 and 18.
It is divided into a machine room 19 on one end (right) side, a heat exchange chamber 20 on the center side, and a heating chamber 21 on the other end (left) side. 22
is a suction port provided on the upper plate of this heat exchange chamber 20, 23 is a heat exchanger arranged along this suction port, the left end is fixed to the left side partition plate 17, and the right end is fixed to the right side partition plate 18, respectively. There is. 24 is a blower, and 25 is a mounting piece of the blower 24, whose rear end is fixed to the rear plate 12 of the heat exchange chamber 20, and its tip is fixed to the front flange piece 26 of the upper plate 6, respectively. As the blower 24 rotates, outside air is sucked in through the suction port 22 and discharged from the discharge grille 8. 27 is a bottom plate of the machine room 19, to which a horizontal rotano compressor (horizontal expansion compressor) 29 is fixed via a support 28. 30 is a refrigerant pipe which connects this compressor 29, heat exchanger 23 and right end plate 3.
It is connected to the service pulp 32 of No. 1. Note that the refrigerant pipes are omitted in FIG. 33 is the bottom plate of the heating chamber 21, which includes a boiler 34, a pump 35, and a pressure tank 36.
is fixed.

The reason for arranging the heating chamber 21 on the left side and the machine room 19 on the right side of the heat exchange chamber 20 in this way is to maintain the overall balance of the heat exchange unit 2, and also to prevent vibrations during operation of the compressor 29. This is also to make it smaller.

To be more specific, heavy equipment such as the compressor 29, boiler 34, pump 35, etc. is distributed to the left and right sides of the heat exchange unit 2, so the center of gravity of the heat exchange unit 2 is approximately near the center of this unit, and the heavy equipment such as the compressor 29, boiler 34, pump 35, etc. It is easy to keep this unit horizontal without tipping when you lift it with your hand.

Moreover, as this compressor 29, what is called a horizontal rotary compressor is adopted. Here, in the horizontal rotary compressor 29, the rotation axis of the rotor is set in the horizontal direction as shown in FIG. direction is greater. However, in this heat exchange unit 2, heavy equipment such as a boiler 34 and a pump 35 are placed opposite to the machine room 19 in which the compressor 29 is housed.
Even if the machine room 19 attempts to vibrate in the vertical direction due to the operation of the compressor 29, this vibration is suppressed to a small level by the boiler 34, pump 35, etc.

37 is a hot water pipe connected to the pump 35, and the left side partition plate 1
7 into the heat exchange chamber 20 , after which this hot water pipe 37 extends along the lower rear edge of the heat exchange chamber 20 .

The hot water pipe 37 passes through the right partition plate 18 and is connected to the hot water valve 38 on the right end plate 31 of the machine room 19 of the heat exchange unit 2.

Here, the reason why the service valve 32 is provided behind the hot water valve 38 is that the service valve 32 is first provided with a refrigerant pipe 39.
This is to connect the hot water valve 38 to the hot water pipe outside the heat exchange unit 2. This is -
This is to secure a working space around the service valve 32 because a tool such as a spanner is used when connecting a refrigerant pipe to the service valve 32 for boat fishing.

When connecting a hot water pipe (not shown) to the hot water valve 38, it is sufficient to simply insert a plug attached to the end of the hot water pipe into the valve 38. Since the service valve 32 and the hot water valve 38 are assembled on the right end plate 31 of the heat exchange unit 2 in this way, these operations can be performed in one place.

A lead wire 39 is connected to the boiler 34 and extends along the upper front edge of the heat exchange chamber 20 through the front edge of the left partition plate 17. The lead wire 39 is guided into the machine room 19 through the front edge of the right partition plate 18 and connected to a terminal 41 of the electrical equipment board 40. In this heat exchange chamber 20, the hot water pipe 37 is placed along the lower rear edge of the heat exchange chamber 20, and the lead wire 39 is placed along the front flange piece 26 of the heat exchange chamber 20. This is to prevent the hot water pipes 37 and lead wires 39 from creating ventilation resistance as much as possible, and also to prevent the lead wires 39 from receiving heat radiation from the hot water pipes 37 as much as possible. Furthermore, even if a portion of the hot water pipe 37 is damaged and water leaks, this is also to prevent water from getting on the lead wire 39.

Reference numeral 42 denotes an inspection lid provided on the left partition plate, which covers the maintenance/inspection opening 43 of the left partition plate 17 as shown in FIG.

That is, reference numeral 44 denotes a latch piece of this inspection lid 42, which is inserted into a notch 45 of the maintenance inspection opening 43. The area around this inspection lid 42 is placed around the maintenance inspection port 43, and the screw (
This inspection lid 42 is fixed to the left side partition plate 17 with a screw (not shown).

The reason why the maintenance inspection opening 43 is provided in the left partition plate 17 and the inspection opening 43 is covered with the inspection lid 42 is that the internal state of the heating chamber 21 can be checked with the heat exchange unit 2 installed. This is to enable confirmation. That is, when performing this check (see Figure 1), first remove the discharge grille 8 or cabinet 15 so that the heat exchange chamber 20 can be seen from below, and then insert your hand into the heat exchange chamber 20 and inspect it. Remove the screw that holds the lid 42, and then remove the lid 42.
If it is removed from the left side partition plate 17, the equipment inside the heating chamber 21 (the boiler 34
, pump 35, etc.).

FIG. 6 shows the combination of the upper plate 6 and the front plate 9.
Reference numeral 6 indicates a reinforcing frame (a part of the front plate) fixed to the lower surface of the upper plate, and 47 indicates the upper edge of the front plate 9, which is bent rearward. The upper edge 47 of the front plate 9 is inserted between this reinforcing frame 46 and the front flange 47 of the top plate 6, and the upper edge 47 of the front plate 9 is discharged forward than the front edge 48 of the top plate 6. That's what I do. This is to prevent rainwater that has adhered to the upper plate 6 and fallen from entering the inside of the heat exchange unit 2.

FIG. 7 is a perspective view of the bottom plate 33 attached to the heating chamber 21 (boiler, pump, etc. are omitted), and a vertical attachment piece 49 is fixed to the front part. This mounting piece 49 is provided with a mounting hole (temporary fixing part) 50 and an opening 51 (
Note that this mounting piece 49 is omitted in FIG. 1). 54
is a screw hole (fixing part) provided in the mounting piece 49, and the mounting hole 50
is inserted into the bent piece 53 of the reinforcing frame 46, and a screw (not shown) is screwed into the screw hole 54.
A mounting piece 49 is fixed to the reinforcing frame 46. When removing this bottom plate 33, as shown in Fig. 8 (boiler,
(Pumps, etc. are omitted) The mounting portion 55 of the bottom plate 33 is connected to the lower edge 52 of the rear plate 12, and the mounting hole 50 of the mounting piece 49 is connected to the reinforcing frame 4.
6, the heat exchange unit 2 is removed from each bent piece 53.
With the unit installed, the bottom plate 33 can be removed from the unit. In this way, since the bottom plate 33 is detachably attached to the heat exchange unit 2, the bottom plate 33
Service inspection of equipment fixed to the machine can be easily performed.

The bottom plate 27 of the machine room 19 described above is also provided with a mounting piece similar to the bottom plate 33 of the heating chamber 21, and this bottom plate 27 is also detachably attached to the heat exchange unit 2.

(g) Effects of the Invention As described above, according to the present invention, the center of the inside of the housing of the heat exchange unit is a heat exchange chamber, one end is a heating chamber, and the other end is a machine room, and a horizontal compressor is installed in this machine room. By arranging the heat exchange unit, the height of the heat exchange unit can be kept low and the head space can be increased when the heat exchange unit is installed on the ceiling.

In addition, by distributing relatively heavy parts (compressor, boiler, etc.) at both ends of the heat exchange chamber and locating the center of gravity of the heat exchange unit approximately in the center of the unit, it is possible to lift the heat exchange unit. When the unit is installed on the ceiling, the unit is less likely to tilt, making the installation easier.
