Abstract

PURPOSE:To reduce the space for installing a heat exchange unit by providing an air duct which, when the suction space on one side is blocked, leads air from the suction space on the other side into the opposite suction space. CONSTITUTION:Where there is no obstruction (for example, a wall of a house) around a heat exchange unit 1 installed, air is sucked into the heat exchanger unit 1 from two sides and discharged upward by rotation of a blower 4. In the case of the heat exchange unit 1 being installed with its right side close to a wall 25 of a house, the suction space 11 on one side is blocked by this wall 25. but air sucked in through an inserted inlet 3 as well as the suction space 10 on the other side is led through an air duct 18 into the opposite suction space 11 and passed through the heat exchanger 9 on the right side so that the effectiveness of the heat exchanger is prevented from declining. Thus this heat exchange unit 1, even if installed with its left side or right side close to a wall 25 of a house or the like, performs its function without hindrance.

Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a heat exchange unit incorporating a heat exchanger, a blower, etc.

(b) Conventional technology As shown in Japanese Utility Model Publication No. 57-59904, an example of the structure of a conventional condenser type heat exchange unit is a combination of two flat heat exchangers in a V-shape, and The blower was placed in a space surrounded by a heat exchanger.

As the blower rotates, air is sucked in from each side of the two heat exchangers and discharged upward.

(c) Problem to be solved by the invention Since air is sucked in from each side of the two heat exchangers, a suction space is required on the sides of the heat exchangers, that is, on the sides of the heat exchange unit. However, the side surface of the heat exchange unit cannot be brought very close to the wall of the house, and there is a possibility that the space of the heat exchange unit 7 cannot be saved.

The present invention aims to solve the above-mentioned problems.

(d) Means for solving the problem In order to solve this object, the present invention arranges a heat exchanger with suction space secured on both sides of the fuselage, so that when one suction space becomes full, the other An air guide path is provided to guide air from the suction space of the two suction spaces to the one suction space. A connection part for a refrigerant pipe connected to a heat exchanger is arranged in this air guide path, and an insertion port for a refrigerant pipe connected to the connection part is provided in the exterior body forming this air guide path. .

(*) Operation When one suction space of the heat exchange unit is vacated, air sucked in from the other suction space is guided to this one suction space by the air guide path. Moreover, the refrigerant pipe insertion port also acts as a suction port.

(f) Embodiment In FIGS. 1 and 2, 1 is a remote condenser type heat exchange unit, 2 is the left and right exterior plates of this unit, and an insertion port 3 is provided at the bottom. 4 is an electrical equipment box attached to the front edge of the right exterior plate 2. Reference numeral 5 denotes an upper plate attached across the left and right circular exterior plates 2, and two nozzles 6 are provided on the upper plate. 7 is a wire guard that covers this nozzle 6. Reference numerals 8 and 9 indicate plate-fin type heat exchangers that act as condensers, and are arranged in a substantially square shape when viewed from the left and right substrates 2. And these heat exchangers 8
, 9 are fixed to the inner surfaces of the left and right exterior plates 2. By arranging the heat exchangers 8.9 in this way, a suction space 10.11 is secured around the heat exchangers 8 and 9. Reference numerals 12 denote left and right side plates, the upper ends of which are fixed to the upper plate 5, and the lower horizontal pieces 13 fixed to the upper end of the heat exchanger 8, respectively. 14
1 is a blower housed in a nozzle, 15 is a motor for driving the blower, and 16 is a support plate for supporting the motor 15, which is attached across the upper ends of the heat exchangers 8 and 9. Therefore, the load of the blower 14, motor 15, etc. is borne by the two heat exchangers 8 and 9. The rotational speed of the blower 14 can be adjusted using equipment inside the electrical box 4.

17 is a wind guide plate that connects the lower ends of the heat exchangers 8 and 9. The air guide plate 17 is thus provided to form an air guide path 18 below the heat exchangers 8, 9 that communicates with the suction space 10.11. The height dimension a of this air guide path 18 is set to about 174 times the height dimension of the heat exchangers 8 and 9.

Therefore, the suction area of the air guide path 18 is also approximately 1/4 of the suction area of the heat exchangers 8 and 9.

FIG. 3 is an explanatory diagram showing the state of the heat exchangers 8 and 9 and the piping connected to the heat exchangers. Reference numerals 19 and 20 are refrigerant inlet headers and outlet headers, respectively, of the heat exchangers 8 and 9. They are arranged in a substantially V-shape along the end plate. The inlet ladder 19 and the exit ladder 20 are connected via refrigerant pipes (broken line arrows) 21 extending in parallel. 22 is a connecting pipe that connects the outlet header 20 of one heat exchanger 8 and the inlet header 19 of the other heat exchanger 9. 23 is an inlet pipe connected to the inlet of one heat exchanger 8 at the bottom of the ladder 19. 24 is an outlet pipe connected to the outlet header 20 of the other heat exchanger 9. These inlet pipes 23 and outlet pipes 24 have their connection parts 26 connected to the insertion ports 3 of the right board 2.
The refrigerant pipe 3 connected to this connection part can be connected to the refrigerant pipe 3.

Then, as shown in Fig. 4, when the heat exchange unit 1 is placed in a place where there are no obstacles (walls of houses, etc.) around it and the blower 4 is rotated, the air flows into the heat exchange unit 1. It is sucked in from both sides and ejected upward. On the other hand, as shown in Figure 5, connect the right side of the heat exchange unit 1 to the wall of the house.
5, one suction space 11 is aerodynamically affected by this wall 25. However, the air sucked in from the other suction space 10 and the insertion port 3 passes through the air guide path 18 and closes to one suction space 11. Guided to the right (I
Air is also allowed to flow through the heat exchanger 9 to suppress a decrease in heat exchange efficiency. In this way, this heat exchanger.

This heat exchange unit 1 can be used without any problem even if the left or right side of the unit 1 is brought close to the wall 25 of a house.

In other words, this heat exchange unit /to 1 can be placed on the left or right side
Since we have made it so that there is no problem in operation even if air is not sucked in from only one side, when installing multiple heat exchange units 1 (for example, 2 or 3 units), please refer to Fig. 6. By connecting the side surfaces of the heat exchange unit 1 as shown in FIG. 7, the installation space for the heat exchange unit 1 can be kept small. In particular, by setting the lateral dimension C of one of the heat exchange units 1 to about half of the lateral dimension of the other, the installation space can be made into a substantially rectangular shape when three units are installed as shown in FIG.

In FIGS. 6 and 7, solid arrows indicate the flow of suction air, and thick lines indicate the insertion port 3, respectively.

(g) Effects of the invention As described above, the present invention provides a guide for guiding air from the other suction space to the one suction space when one suction space of the heat exchange unit is used. Since the air passage is provided, even if the heat exchange unit is placed close to the wall of the house, the operation of the heat exchange unit can be prevented from being hindered. Furthermore, the heat exchange unit can be installed so that its sides are connected, thereby reducing the installation space.

In addition, the insertion port for the piping connected to the refrigerant pipe of this heat exchange unit is provided on the exterior plate that forms the air guide path, so if this heat exchange unit is placed close to the wall of a house, this outlet will also be used for air intake. It acts as a vent and can prevent ventilation resistance from increasing.
