Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an air conditioner with a ventilation function, and particularly relates to reducing pressure loss in a ventilation duct.

[Prior Art 1] FIGS. 4 and 5 are a perspective view and a cross-sectional view of an air conditioner with a ventilation function and a piping structure shown in, for example, Japanese Utility Model Publication No. 62-40259.

The ventilation duct (18) and the sleeve (6) are equipped with a refrigerant pipe (lO) and a drain hose (full) that are connected to the indoor unit of the air conditioner, as well as an electrical communication line (16) that electrically connects the indoor unit and the outdoor unit. ), and a ventilation air passage (13) is inserted separately.

Next, the operation will be explained. In Figures 4 and 5,
The air sucked in from the room by the back fan on the indoor side, or the air that flows through the ventilation duct 1- (181) connected to it, and then passes through the ventilation air passage (17) in the sleeve (6) to the outside. It is discharged.

[Problem to be solved by the invention] In the conventional -F device, the refrigerant pipe (
10), drain hose (11), electrical connection line (1)
All of the spaces except for the space in 6) are provided with ventilation air passages (
17), the absolute cross-sectional area of the air passage is small, and the pressure loss in this area increases by approximately 25%, which has a large effect on the exhaust air passage. Furthermore, there were other problems such as large air blowing noise due to this high pressure loss.

The air conditioner with a ventilation function according to the present invention has less pressure loss in the ventilation air path, can reduce the load on the ventilation blower, and has less influence on the exhaust air volume.

The purpose is also to reduce the noise level on the indoor side.

[Means for Solving the Problems] The air conditioner with a ventilation function according to the present invention is one in which a sleeve through which refrigerant piping, electrical wiring, and a drain hose connecting an indoor unit and an outdoor unit are inserted also serves as a ventilation duct. , a pipe bundle that integrates the refrigerant pipes, electrical wiring, and one hose.

[Effect 1 The air conditioner with ventilation functions A'-J in this invention is as follows.

By bundling the pipes, an air path can be secured, and by reducing pressure loss in this area, the load on the ventilation blower can be reduced, and indoor noise can be reduced.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. 1st
In Figures 2 and 3, (io) is a refrigerant pipe;
(11) is the 1~len hose, and (16) is the electrical connection line. (6) is a sleeve that leads these out of the room.
It has a ventilation air passage (17) and serves both roles. (7) is a ventilation blower, (5) is a duct 1~ that passes through to the front side of the indoor unit, and is integrated with the sleeve (6) to form a ventilation air passage; (8) is an intake/exhaust port on the indoor unit side of the ventilation part; (9) is
This is an air intake/exhaust port on the outside of the room. (12) is the refrigerant pipe (10)
, a drain hose (11), and an electrical connection line (16) are integrated within the sleeve (6), and this includes a guide (13) to ensure an air path within the sleeve (6). ) or are having trouble installing it.

In the case of exhaust, indoor air is sucked in by the ventilation blower (7) through the intake/exhaust port (8) on the indoor unit side, and then the air is sucked into the duct (5).
, through the sleeve (6), and is blown out from the outdoor intake/exhaust port (9). Conversely, in the case of intake, the ventilation blower (7) rotates in the opposite direction, and outdoor air is sucked in through the outdoor intake/exhaust port (9).
It passes through the sleeve (6), the duct 1-(5), and is blown out from the indoor unit side intake/exhaust port (8).

When air flows inside the sleeve (6), the cross-sectional area that can be secured as an air path is approximately 10% compared to the conventional example.
(That is, the wind speed for the same air volume is reduced by 10%. If we consider this in terms of pressure loss, it is thought to be reduced by about 25%, and the noise value can be reduced by about 10%.

Furthermore, piping tabs (12) with guys 1 to (I3)
By using this, it is possible to avoid the 40% difference in performance that sometimes occurs during installation, that is, the difference in performance between the maximum and minimum, without causing any discomfort.

In addition, in the above embodiment, since the purpose is for intake and exhaust, a reversible axial fan is used, or if only exhaust is used, an axial fan or a turbo fan is used.

It is also possible to use a sirocco fan.

[Effect of the invention 1 As described above, according to the air conditioner with ventilation function of the present invention, the sleeve through which the refrigerant piping connecting the indoor unit and the outdoor unit, the electrical wiring, and the drain hose are inserted can also be used as a ventilation duct. Since the refrigerant piping, electrical piping, and drain hose are configured to be integrated into a pipe bundle, a ventilation air path is secured, pressure loss is reduced, and the load on the ventilation blower can be reduced. At the same time, indoor noise can be reduced.
