Problems solved by technology

In Patent Document 2, although the air mixing promotion member is installed near the heat exchanger, the temperature and humidity distribution of the exhaust air is averaged, but when the air direction control plate is placed close to the heat exchanger, the air mixing cannot be installed. There is a problem of dew condensation on the wind direction control plate due to the influence of the wake flow of the heat exchanger.

Embodiment approach 1

[0025]

[0026] figure 1 It is a perspective view of the indoor unit 100 of the air conditioner according to Embodiment 1 of the present invention. Such as figure 1 As shown, the indoor unit 100 includes a casing 50 having a substantially rectangular parallelepiped shape. The casing 50 includes a front panel 52 on the front side of the indoor unit 100 . A rear panel 51 is provided on a surface of the casing 50 that faces the front panel 52 . The indoor unit 100 has a structure in which the rear panel 51 is attached to an indoor installation wall surface and fixed. Two suction ports 60 are arranged on the upper surface of the casing 50 . In addition, a discharge port 70 is provided on the lower surface of the casing 50 .

[0027] figure 2 is the same as figure 1 An explanatory diagram of a cross-section AA of the indoor unit 100 perpendicular to the longitudinal direction. Section AA is a section passing through the center of the axial fan 2 . use figure 2 The int...

Embodiment approach 2

[0054] In the indoor unit 200 of the air conditioner according to the second embodiment, the structure of the refrigerant passage 80 of the heat exchanger 1 is changed from the indoor unit 100 of the air conditioner according to the first embodiment. Hereinafter, Embodiment 2 will be described centering on changes from Embodiment 1. FIG. Items not particularly described in the second embodiment are the same as those in the first embodiment, and the same functions and configurations are described with the same reference numerals.

[0055] Figure 4 It is a diagram showing the refrigerant flow path 80 of the heat exchanger 201 according to Embodiment 2 of the present invention. Such as Figure 4 As shown, the refrigerant inlet 281 of the heat exchanger 201 may also be disposed on the rear panel 51 side, that is, the heat exchange block 210d closest to the rear side air passage wall. When the refrigerant inlet 281 and the refrigerant outlets 283 and 284 of the heat exchanger 2...

Abstract

The present invention provides an indoor unit of an air conditioner capable of suppressing dew condensation on a wind direction control plate arranged in the vicinity of a heat exchange block. The indoor unit of an air conditioner according to the present invention includes: a casing; a suction port provided in the casing; a discharge port opened on the lower surface of the casing; and a heat exchanger arranged in an air passage from the suction port to the discharge port a fan, which is arranged on the windward side of the heat exchanger in the air passage; and a wind direction control plate, which is arranged in the air passage from the heat exchanger to the discharge port. The heat exchanger is configured by arranging a plurality of heat exchange blocks in the front-rear direction of the casing, and includes a refrigerant inlet through which the refrigerant flows into the heat exchanger, and a refrigerant outlet through which the refrigerant flows from the heat exchanger. Exchanger outflow. The wind direction control plate is disposed close to one of the heat exchange blocks, the refrigerant outlet is disposed in the heat exchange blocks other than the heat exchange block disposed close to the air direction control plate, and the number of installation locations of the refrigerant outlet is larger than that of the refrigerant inlet. many.

Description

technical field [0001] The present invention relates to a structure of a heat exchanger of an indoor unit of an air conditioner, and an air conditioner including the indoor unit of the air conditioner. Background technique [0002] The indoor unit of a conventional air conditioner is composed of structural equipment such as a heat exchanger, a fan, and a wind direction control panel, and a box-shaped casing in which these are built. The indoor unit circulates a refrigerant between the indoor unit and an outdoor unit connected to the indoor unit through piping. The heat exchanger cools or heats the air by dissipating or absorbing heat between the air ventilating the heat exchanger and the refrigerant flowing through the heat exchanger. Then, the cooled or heated air is discharged from the discharge port, thereby adjusting the temperature of the air in the room. As an indoor unit of such an air conditioner, in order to improve the performance of the air conditioner by improv...
