Description

[Detailed Description of the Invention] The present invention relates to an improvement of an integrated air conditioner in which a refrigeration cycle is housed in a single case, and is capable of achieving high efficiency and low noise.

Conventionally, this type of integrated air conditioner has been constructed as shown in FIGS. 1 and 2. That is,
In the figure, an integrated air conditioner a has a board b,
An indoor ventilation system path c and an outdoor ventilation system path d are placed on the board b.
It is constructed by providing a partition wall e, an outer box f, etc. that separate the two parts. The outdoor ventilation system path d includes an outdoor heat exchanger b installed facing the back surface g, a motor i installed with its rotation axis perpendicular to the partition wall e,
an axial fan j that blows air toward an outdoor heat exchanger b attached to one end of this motor i;
Compressor k etc. are installed. Further, in the indoor ventilation system path c, there is an indoor heat exchanger m attached facing the front, which is attached to the other end of the motor i and blows the wind passing through the indoor heat exchanger m to the wind tunnel part n. Multi-winged fans were installed.

Here, the configuration of an ideal ventilation system path for this type of integrated air conditioner will be explained. Needless to say, the lower the resistance of the ventilation system path, the better, but to achieve this, the area through which the air passes through the heat exchanger (hereinafter referred to as the front area), which is the element that makes up the resistance, must be wide and the depth through which the air can pass. (hereinafter referred to as the number of rows) is short, and the ventilation system path is wide and smooth with few bends. Only when these conditions are met will a ventilation system path with low ventilation resistance be constructed, making it possible to realize an integrated air conditioner that can blow a large volume of air with low noise using a small-capacity motor.

However, conventionally, this type of integrated air conditioner is installed through a wall or installed in a window, so the front area is limited to the amount of light from the window, etc., so that there is no need to make a large hole in the wall. It was made as small as possible to avoid significant damage.

In addition, conventionally, this type of air conditioner was first designed to reduce costs by making it smaller.
As shown in Figures 2 and 2, since the focus is on driving the multi-blade fan o on the indoor side and the axial flow fan j on the outdoor side simultaneously with one motor i, the front side of the integrated air conditioner a The indoor heat exchanger m and the outdoor heat exchanger h have to be placed along the back surface g, and therefore the indoor and outdoor ventilation inevitably flows through these heat exchangers m and h. Routes c and d are narrow and curved routes, and in order to secure these routes c and d, the front and rear g
The structure was such that the distance between them could not be made very small. Therefore, in the end, a fairly large capacity motor i is required for ventilation, and each heat exchanger m, h
Since the front surface area of motor i and heat exchangers m and h must be made smaller, it becomes necessary to increase the number of rows of each heat exchanger m and h to increase the depth dimension.
Both were expensive, had a long body depth, and were heavy. This results in the opposite of the original purpose of making the fan motor i cheaper, and it cannot be said to be a good ventilation structure. In other words, as mentioned above, priority is given to installing two fans o and j at both ends of one motor i inside a limited box, so the multi-blade fan o, the blowing side of the axial fan j, and It was not possible to make the shape of the air outlet side such that these fans o and j could be operated with low noise. Therefore, the conventional structure inevitably had major problems such as generating a large amount of noise, requiring a large-capacity motor, and being bulky. In addition, a compressor k is installed in the outdoor ventilation system path d to block the ventilation of the axial fan j, which increases the resistance of the outdoor ventilation system path d, ultimately reducing the air volume and increasing noise. , which was increasing the cost of the motor.

The present invention eliminates the above-mentioned drawbacks of the prior art, and the present invention will be described below as shown in the attached drawings showing an embodiment thereof.
The explanation will be given with reference to FIG. 4, FIG. 5, and FIG. 6.

Reference numeral 1 designates the main body of the integrated air conditioner, which is composed of a base plate 2, a partition wall 3 provided on the base plate 2 and separating an indoor ventilation system path A and an outdoor ventilation system path B, an outer box 4, etc. ing. The indoor ventilation system path A includes an indoor heat exchanger 6 installed facing the front surface 5, a multi-blade fan 7 for sucking indoor air from the front surface 5 side and supplying ventilation to the indoor heat exchanger 6; An indoor fan motor 8 for driving the multi-blade fan 7 and a wind tunnel section 10 for guiding the wind blown from the multi-blade fan 7 into the room from an air outlet 9 at the upper part of the front surface 5 of the main body 1 are provided. . Furthermore, the outdoor ventilation system path B includes the top surface 11 of the outer box 4 and the left and right suction ports 23, 24.
It forms a substantially V-shape from the ridges 14 and 15 where the left and right sides 12 and 13 intersect, respectively, to the vicinity of the center of the board 2, and is arranged to fit inside this center part 16 and the edge H of the board 2. The outdoor heat exchanger 17 is positioned so that its rotating shaft is approximately perpendicular to the substrate 2, and its rotating surface is aligned with the top surface 11 of the outer box 4.
An axial fan 18 provided nearby, an outdoor fan motor 19 that drives the axial fan 18, an outlet 20 that sends out air blown by the axial fan 18, and a central portion 16 of the outdoor heat exchanger 17. A horizontal high-pressure type rotary compressor 22 is provided, which is located substantially above the substrate 2 so that a part of the outer shell 21 covers the edge H of the substrate 2. Note that the portion of the board 2 located in both ventilation system paths A and B is the partition wall 3.
The two are connected through a hole (not shown) cut out at the lower end of the two, so that condensed water generated in the indoor heat exchanger 6 can be stored together.

The operation in the above configuration will be explained. In the indoor ventilation system path A, a multi-blade fan is rotated by the rotation of the indoor fan motor 8, and the air that is sucked in from the room, passes through the indoor heat exchanger 6, and undergoes heat exchange is sent to the wind tunnel section 10 and further blown out. It is blown out from the mouth 9 into the room. Here, the indoor fan motor 8 is different from the case of a conventional integrated air conditioner, and the outdoor fan motor 1
9 and is designed exclusively for indoor use, so a unique rotation speed can be selected so as to optimally ventilate the indoor ventilation system path A. Furthermore, when selecting the position of the indoor fan motor 8, there is no need to take into account the position of the outdoor fan or the indoor fan, so the indoor ventilation system path can be selected independently from the outdoor ventilation system path B. Therefore, it is possible to make the indoor ventilation system path A as small as possible, and at the same time to downsize the indoor heat exchanger 6 and reduce costs. If the indoor side ventilation system path A can be made smaller in this way, the depth dimension of this compartment outside ventilation system path B can be made considerably wider than before. That is, in the outdoor ventilation system path B,
The outdoor heat exchanger 17 has both ends 25, 26 close to the ridges 14, 15 of the outer box 4, and the center part 16 is located near the center of the board 2, forming a so-called approximately V-shape to increase the ventilation area. This makes it possible to improve the performance of the outdoor heat exchanger 17, reduce ventilation resistance, and reduce costs.

Furthermore, since the area of the portion of the outdoor ventilation system path B that corresponds to the top surface 11 can be increased, the large diameter axial flow fan 18
In addition, when the air sucked in from the left and right side surfaces 12 and 13 is blown out from the air outlet 20 on the top surface 11, the air flow becomes almost linear, which reduces the resistance of the outdoor ventilation system path B. be able to. As a result, a large amount of air can be blown with low noise, and as in the case of the indoor ventilation system, the input to the outdoor fan motor 19 can be small, so the outdoor heat exchanger 17 and the outdoor fan motor 19 can be made smaller. , it becomes possible to reduce costs. In addition, the center portion 16 of the outdoor heat exchanger 17 is exposed to condensed water generated by the cooling action of the indoor heat exchanger 6 located within the edge H of the substrate 2, and the indoor heat exchanger is cooled and its efficiency is increased. improves. In particular, the V-shaped outdoor heat exchanger 17 is very effective in improving efficiency because the portion with poor ventilation (near the central portion 16) is exposed to condensed water. Further, the condensed water warmed by the outdoor heat exchanger 17 reaches a temperature at which it can easily evaporate, and natural evaporation of the condensed water is promoted. In addition, the horizontal high-pressure type rotary compressor 22 is located directly above the center part 16 of the outdoor heat exchanger 17 so that a part of its outer part 21 is immersed in condensed water, so it is not exposed to ventilation. In addition, the heat from the outside is dissipated into condensed water, which improves the efficiency of horizontal high-pressure rotary compressors.
Another advantage is that the center of gravity is low, making it difficult for the body to vibrate.

In this way, the present invention provides a partition wall in the outer box to form indoor and outdoor ventilation system paths, and also installs an indoor fan and an indoor heat exchanger in the indoor ventilation system path, and an indoor ventilation system path in the outdoor ventilation system path. Each of the indoor and outdoor blowers is equipped with an outside blower, an outdoor heat exchanger, and a compressor. The outdoor side blower is disposed adjacent to the outdoor side heat exchanger, and the outdoor side heat exchanger has a substantially V-shape with both ends located at the ridges where the left and right sides and the top surface of the outer box intersect, and the center part located on the board. The compressor is arranged directly above the central part, and both the compressor and the central part are located in condensed water stored on the substrate, and there are suction ports on the left and right sides of the outer box, and air outlets on the top surface. Since the openings are formed separately, each indoor and outdoor blower is independent, so that each indoor and outdoor ventilation system path can be optimally selected without being influenced by one ventilation system path.
In other words, by making the indoor ventilation system path smaller, the width of the outdoor ventilation system path can be increased, and as a result, the outdoor heat exchanger can be formed into a substantially V-shape and have a large area, reducing ventilation resistance. For example, a large-diameter axial fan can be used to blow a large amount of air with low noise. In addition, the central part of the outdoor heat exchanger is cooled by being placed in the condensed water collected on the substrate, which makes it possible to further improve the efficiency of the heat exchanger and to warm the condensed water to promote natural evaporation. Furthermore, since the compressor is located directly above the central part of the outdoor heat exchanger and in the condensed water on the board, the resistance of the outdoor ventilation system can be reduced and noise can be lowered, and the efficiency of the compressor itself can also be improved. can be increased.
