Benefits of technology

The present invention relates to an improvement in the design of an indoor unit for an air conditioner. The technical effects of this invention include reducing the space required for the liquid-side pipe and the overall size of the indoor unit. Additionally, the invention allows for more efficient cooling of the indoor heat exchanger. This is achieved by placing an expansion valve and a flow divider body in a specific location, allowing for greater installation space for the indoor fan and reducing the space outside the indoor heat exchanger. Furthermore, the invention reduces the installation space for the liquid relay pipe, which connects the expansion valve and the flow divider body, by placing it over the bent tube portion. This allows for further downsizing of the indoor unit.

Problems solved by technology

As a result, in the indoor heat exchanger, the refrigerant absorbs heat from the indoor air, and consequently evaporates.
As a result, in the indoor heat exchanger, the refrigerant dissipates heat to the indoor air, and consequently condenses.

Embodiment Construction

[0026]Embodiments of the present invention will be described in detail below with reference to the drawings. The following description of embodiments is merely an illustrative one in nature, and does not intend to limit the scope of the present invention or applications or uses thereof.

[0027]An embodiment of the present invention is an air conditioning device (10) configured to cool and heat indoor air. As illustrated in FIG. 1, the air conditioning device (10) includes an outdoor unit (11) installed outdoors and an indoor unit (20) installed indoors. The outdoor unit (11) and the indoor unit (20) are connected with each other through two communication pipes (2, 3), which thus forms a refrigerant circuit (C) in this air conditioning device (10). In the refrigerant circuit (C), a refrigerant injected therein is circulated to perform a vapor compression refrigeration cycle.

[0028]

[0029]The outdoor unit (11) is provided with a compressor (12), an outdoor heat exchanger (13), an outdoor ...

Abstract

A gas-side pipe (70) is provided with a header body (71a) extending vertically along a side end portion (32a) of an indoor heat exchanger (32), a vertical tube portion (74) facing the header body (71 a), and a bent tube portion (73) connecting a lower end portion of the header body (71 a) and a lower end portion of the vertical tube portion (74) together. Part of a liquid-side pipe (80) is provided in a space (S1) between the header body (71a), the vertical tube portion (74), and the bent tube portion (73).

Description

TECHNICAL FIELD[0001]The present invention relates to an indoor unit for an air conditioning device, and more particularly relates to a measure to save spaces for pipes around an indoor heat exchanger.BACKGROUND ART[0002]Air conditioning devices for cooling or heating an indoor space have been known. For example, an air conditioning device disclosed in Patent Document 1 includes a casing, an indoor fan housed in the casing, an indoor heat exchanger provided to surround the indoor fan, a gas-side connection port connected to a gas-side communication pipe, and a liquid-side connection port connected to a liquid communication pipe. In other words, its indoor unit is connected with its outdoor unit through the liquid communication pipe and the gas communication pipe.[0003]The gas-side pipe is provided with a header, and the liquid-side pipe is provided with a flow divider. The header includes a header body and a plurality of branch pipes branching from the header body and connected to a...
