To provide.

Hereinafter, the present invention will be described in more detail with reference to one embodiment of the present invention and an air conditioner for cooling. However, the scope of the present invention is not limited by the following examples and drawings, and the scope of the present invention will be limited only by the contents described in the claims below.

1 to 4 show the structure of an outdoor unit for a front suction type air conditioner according to an embodiment of the present invention.

An outer frame 4 is fixedly installed on a rectangular inner wall of a rectangular space formed on the outer wall 2 of a residential and / or commercial building, and an inner frame 6 inside the outer frame 4, and the outer frame 4. It is fixed to the installation. In some cases, the inner and outer frames 4 and 6 may be integrally formed. The inner region of the inner frame 6 is divided into a suction region 7a and a discharge region 7b, and a plurality of louver blades 8 are provided in each region to fill the gap between these louver blades 8. Air is sucked in or discharged through it. The direction of the louver blade 8 may be manipulated to adjust the direction in which air is sucked and / or discharged.

On the other hand, the outdoor unit 10 fixedly installed inside the building exterior wall 2 so as to contact the outer frame 4 and / or the inner frame 6 has an outdoor unit casing, which is the component shown in FIG. 2. In addition, the outdoor unit components shown in FIG. 2 are also installed inside the outdoor unit casing.

First, one side of the outdoor unit casing facing the suction area 7a and the discharge area 7b of the inner frame 6 is opened, and the open side part is divided into the suction part 11a and the discharge part 11b. Separated to correspond to the suction region 7a and the discharge region 7b of the inner frame. The other three side covers 12a, 12b, and 12c, the bottom cover 14, and the top cover 16 are closed to form an overall cuboid shape. In addition, the outdoor unit casing may be classified into a suction casing corresponding to the suction part 11a and a discharge casing corresponding to the discharge part 11b. The bottom cover 16 has a plurality of leg members 18a, 18b, 18c, and 18d protruding outward from the bottom cover 16, and these leg members 18a, 18b, 18c, and 18d are formed on the floor of the building, e.g. Is supported on the floor to support the heavy load of the outdoor unit (10). The number of leg members 18a, 18b, 18c, and 18d may be preferably about four when considering the shape of the bottom cover 14. In addition, a leg reinforcement 19 for connecting and reinforcing these leg members 18a, 18b, 18c, and 18d to each other is formed in the transverse direction under the bottom cover 14. In addition, the leg members 18a, 18b, 18c, and 18d further include a height-adjustable screw (not shown), so that when the flatness of the floor of the building, for example, the floor of the apartment veranda is not correct, the outdoor unit ( It can be used to level 10. In addition, when two of the leg members 18a, 18b, 18c, 18d, for example, the front (building outer wall side) two leg members 18a, 18b further include a moving wheel (not shown), It becomes quite convenient to carry the heavy load outdoor unit 10.

In addition, the compressor 20 is installed on the compressor fastening part 22 in the outdoor unit suction part 11a, and the "cool" air-cooled condenser 30 has the condenser cover 32a, 32b, 32c and the condenser bracket 34a. , 34b are fixedly supported to the side covers 12a and 12b and the bottom cover 14. Air-cooled condenser 30 has a plurality of rows of condenser piping between the many condenser fins has a zigzag shape. The structure and shape of the air-cooled condenser are not shown in detail because they are already known. The compressed refrigerant gas compressed from the compressor 20 flows through the pipe of the condenser 30 and is condensed by taking heat of condensation into air supplied from the outside. In this case, the condenser covers 32a, 32b, and 32c and the condenser brackets 34a and 34b form an air path so that air introduced from the outside is not supplied to the discharge part 11b without passing through the condenser 30. As a result, the outside air sucked in through the gap between the louver blades 8 of the intake area 7a is “bounced” along the air path formed by the condenser covers 32a, 32b, and 32c and the condenser brackets 34a and 34b. Heat exchange with the refrigerant gas flowing through the condenser pipe while passing through the magnetic condenser (30).

In particular, unlike the outdoor unit of the type in which the outside air is sucked into the three side surfaces and the air heat-exchanged to the upper surface is discharged, the suction surface is limited in the present invention employing the front suction discharge method, so the suction resistance is large in the system. Thus, in a preferred embodiment of the present invention a sirocco fan is used. That is, the sirocco fan 40 supplies external air to the outdoor unit discharge part 11b to the air-cooled condenser 30 through the suction area 7a and discharges heat-exchanged air through the discharge area 7b. Is installed. Such a sirocco fan may be installed so that the suction orifice 36 faces up and down, and the suction orifice 36 may face the side covers 12a and 12b.

In addition, as shown in Figure 2, in order to minimize the vibration caused by the operation of the fan to the system is required a fan support member for fixing the sirocco fan 40 to the outdoor unit casing, these support members as shown The fan frame 42 for reinforcing and supporting the corners of the discharge portion, and the fan bracket 44 for connecting and fixing the side of the sirocco fan 40 to the fan frame 42. The shape of the fan bracket 44 may vary depending on the installation direction of the sirocco fan. In addition, as described above, when the outdoor unit casing is divided into a suction casing corresponding to the suction part 11a and a discharge casing corresponding to the discharge part 11b, the fan frame 42 reinforces and supports the discharge casing. do. Reference numeral 46 denotes a fan front installed in front of the sirocco fan 40, and reference numeral 50 denotes a control box for controlling the outdoor unit operation.

When the outdoor unit having the above configuration is installed in the louver frame fixedly installed on the rectangular inner wall of the space formed on the outer wall of the building, as shown in FIG. 1, the outdoor unit configuration of the front suction method can be obtained. However, in the case of a multi-family house that has been established as a mainstream residential lifestyle with the recent urban development, the structure of adjacent houses is symmetrical with each other, so if the outdoor unit is located on one side of the porch in one house, the outdoor unit is also in the next door. It is placed on one side of the building, but is located adjacent to the outdoor unit of the neighboring house. Figure 3 shows this example schematically, if the high-rise apartment house as shown in Figure 4, the houses facing each other are built symmetrically with each other, as shown in the figure where the outdoor unit is to be installed adjacent to each other, There is no choice but to.

In FIG. 4, the outdoor unit is installed on the right side of No. A on the nth floor. However, if the outdoor unit is installed on the left side of A, the outdoor unit is installed on the right side in No. B, and the outdoor unit is installed on the left side in No. C. Will be installed, so that the outdoor units of B and C are similarly adjacent to each other.

In this case, if the discharge direction of the air from the sirocco cooling fan is toward the nearest outdoor unit, the air discharged after the heat exchange is sucked into the suction unit of the nearest outdoor unit or the upper layer (that is, the n + 1th or n + 2th layer). It is sucked into the suction unit of the outdoor unit of the to reduce the heat exchange efficiency of the neighboring outdoor unit. That is, the fresh air is not sucked through the suction unit, and the high-temperature waste air discharged from the outdoor unit below is sucked through the suction unit, which inevitably reduces heat exchange efficiency.

In order to solve this problem, the present invention is characterized by discharging the air heat exchanged from the cooling fan in a direction away from the nearest outdoor unit. 3 shows this discharge direction with an arrow. As can be seen from the partially cutaway perspective view shown in Fig. 3, the discharge direction of the sirocco fan of No. A is opposite to the discharge direction of the sirocco fan of No. B. As shown in FIG. In the example shown in FIG. 3, the rotational direction of the sirocco fan motor and the rotational direction of the sirocco fan motor B in FIG. However, this assumes that an orifice is used as a cooling fan with a sirocco fan facing up and down, and as described below, if other types of fans and air guides are used, the nearest outdoor outdoor can be adjusted simply by adjusting the direction of the air guide. The discharge direction of the period can be adjusted to be opposite to each other. In this case, in order to reduce the discharge resistance of the waste air discharged from the discharge portion, the louver of the discharge portion may be formed in the vertical direction.

As described above, when the discharge direction is controlled by the neighboring outdoor unit, as shown in FIG. 4, the waste air discharged from one outdoor unit (eg, outdoor unit B) is adjacent to the outdoor unit (eg, outdoor unit A or C). However, it is less likely to be sucked into the suction part of the neighboring outdoor unit upstairs (for example, outdoor units of No. D, E or F), thereby improving the heat exchange efficiency of the outdoor unit installed in the whole apartment.

In the above description, the present invention has been described using the sirocco fan having an orifice formed up and down for convenience of description, but for implementing the technical idea of the present invention within the scope described in the following claims. Fans or guide tubes (for example, the use of axial fans and air guides) can be used.

As described above, according to the present invention, in a multi-unit house in which a large number of outdoor air conditioner air conditioner outdoor units can be installed, the reduction of heat exchange efficiency of the outdoor unit by the neighboring outdoor unit is minimized, and the neighboring outdoor unit by the outdoor unit is provided. It is possible to provide an outdoor unit structure that can minimize the reduction in heat exchange efficiency. Accordingly, it is possible to minimize the interference of the outdoor period of the front suction system is installed in individual households in a large multi-family house.
