Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a configuration of an indoor unit for a separate air conditioner of a heat pump that performs air conditioning.
[0002]
[Prior art]
As shown in FIG. 9, a general air conditioner indoor unit is attached in a state where the indoor unit body 1 protrudes from the wall surface of the room. FIG. 10 is a vertical cross-sectional view taken along the line DD, and the configuration thereof is a cross flow fan 6 disposed in a place surrounded by a front grill 2, a heat exchanger 3, a casing 4 and a stabilizer 5 in order from the windward side. It consisted of a blowout port having a wind direction changing blade 7. The cross flow fan 6 is rotated by a motor (not shown) to produce a blowing action, and air flows and is dehumidified by flowing air as indicated by the arrows in the order described above.
[0003]
[Problems to be solved by the invention]
However, the indoor unit of the separate type air conditioner having the above structure is originally designed on the condition that it is installed on the central wall surface of the room, but it is installed on a business trip on the wall of the room. There was a problem in the fusion with the room interior as well as giving the room a sense of pressure. As a result, about 70% of the actual market is located in the corner of the room. In addition, it is often arranged for large living rooms and building conference rooms using the wall surface of the room. At this time, there is a limit to how much the wind direction changing blade can be devised in the conventional indoor unit structure, and the entire large room It was impossible to quickly heat and cool the air without temperature unevenness.
[0004]
Therefore, we have already proposed a quarter-arc fan-shaped indoor unit for heating and cooling that has excellent interior characteristics and allows sufficient airflow control even from the corner of the room. This is designed on the assumption that the indoor unit body 10 is attached to the corner of the room as shown in FIG. FIG. 12 is a view of the air-conditioning indoor unit having a fan shape of a quarter arc as viewed from the lower surface, FIG. 13 is a longitudinal sectional view taken along the line EE, and the configuration thereof includes the suction grill 11 on the lower surface. And has a blowout port 12 in the arc portion. The air outlet 12 is provided with wind direction changing blades 13 along a circular arc. When the cross-flow fan 14 rotates and blows air, the air is sucked from the suction grill 11 on the lower surface, and heat is exchanged via the heat exchanger 15 constituted by two parts, and the arc-shaped outlet 12 Air flows into the air and acts as a blower. 16 is a water tray for processing the condensed water of the heat exchanger, and 17 is a toy for processing the condensed water of the heat exchanger in the inclined portion and guiding it to the water tray.
[0005]
The blowout port 12 composed of the stabilizer 18 and the rear guider 19 blows out substantially horizontally as shown in FIG. 13 in the cross section of the arcuate central part, and blows out downward in the cross section of both ends. The I part of FIG. 13 is completely horizontal, and the I part gradually recedes from the EE cross section of the outlet 12 toward the FF cross section. Further, near the FF cross section, the air outlet is directed substantially downward, and gradually changes in three dimensions to keep the height of the air outlet horizontally. With such a configuration, the air flowing along the vicinity of the wall faces downward, the air flowing toward the center of the room faces in the horizontal direction, and the air flow easily reaches the entire room without unevenness, and comfort is also improved. .
[0006]
On the other hand, in the commercial air-conditioning field, there are cases where ceiling built-in type or ceiling-suspended type are arranged in the middle of the room or in several places, but further improvement has been demanded for air flow distribution control. The ceiling-suspended type was not very well-designed. In recent years, there is an increasing need for such an air conditioner that requires a full-fledged air cleaning function.
Therefore, the present invention solves such a problem, and combines the conventionally proposed indoor unit for cooling and heating with an air purifying unit having an equivalent shape, so that it can be integrated with the interior property in a large room, In addition, it proposes a sufficient air blowing capacity and air flow control in an indoor unit suitable for being arranged in a corner, and also provides a sufficient air cleaning function.
[0007]
[Means for Solving the Problems]

The indoor units 101 and 103 for air conditioning and heating suck air from the suction grill on the lower surface, and through a turbo fan in which dust is sufficiently removed and deodorized through a high-performance HEPA filter and a light regeneration adsorption filter through a turbofan installed at the rear. It is blown into the room.
[0019]
In addition, in the indoor units 100 and 102 for cooling and heating, air is sucked from the suction grill on the lower surface, heat is exchanged via the heat exchanger constituted by two parts, and the air flows to the arc-shaped outlet, thereby cooling and heating. The air blowing action that contributes to. As a result, a comfortable air-conditioning effect and a sufficient air cleaning function can be provided. Moreover, about the case where it comprises in such a substantially circular shape, it is desirable to arrange | position an air purifying unit so that it may become alternate.
[0020]
The light regenerating adsorption filter in the above example could be regenerated with sunlight, an ultraviolet lamp or the like by highly dispersing fine particle anatase type titanium dioxide with zeolite having a high silica ratio as a main adsorbing component. Although it does not specifically limit as a cycle to reproduce | regenerate, What is necessary is just to implement suitably in the level which a user is not dissatisfied with adsorption | suction performance. Specifically, although it depends on the amount of adsorbent supported, approximately 6 months is a standard. The high-performance HEPA filter is a general term for filters having an ability to remove 99.97% of particles of 0.3 μm at usually 25 mmAq or less.
[0021]
Moreover, in the said Example, when not carrying out air conditioning, only the air cleaner unit can be made to operate independently.
[0022]
In the above embodiment, the light regeneration adsorption filter is used. However, in the present invention, a heat regeneration filter can also be used. In heating regeneration, combustion oxidative decomposition is performed without desorbing odors by dispersing and supporting an adsorbent such as high silica zeolite and catalytic metals such as Pt and Pd and heating to about 300 ° C. In order to obtain sufficient adsorption performance in terms of shape, a corrugated honeycomb type is desirable.
In the examples, a high-performance HEPA filter was used, but the filter that can be used in the present invention is a high-performance dust collection filter, which is a type that has a large pressure loss even if it conforms to HEPA, specifically, a filter that is 10 mmAq or more. Is preferably a separate air blowing circuit.
[0023]
Moreover, in the said Example, although the turbo fan was used as a ventilation fan for an air purifying function, if it is a fan with a high static pressure, it will not be limited to this. Other sirocco fans can also be used. However, there are no other products that can perform without any problems even if the current pressure loss is 5 mmAq or more.
[0024]
In the above embodiment, the air-conditioning indoor unit blower circuit for air-conditioning has no air purifying function. However, if the pressure loss is small, the air-conditioning performance is hardly affected. It is also possible to arrange.
[0025]
