[Problems to be solved by the invention]
However, in the configuration of the air conditioner having the oxygen enrichment means of the above-described conventional technique, there is a problem that the size of the outdoor unit inevitably increases in the height direction. For example, when an outdoor unit is attached to the ceiling, there is a possibility that a problem such as having to use a dedicated installation tool may occur. In particular, the decompression means provided in the oxygen enrichment means is usually a decompression pump or the like, and requires an appropriate height due to the structure of the casing. Therefore, in the conventional technology, the oxygen enrichment means is disposed under the restriction. The height of the space can be determined. Furthermore, the power supply unit including the control board and the like arranged in a plane provided in the outdoor unit is usually arranged in the upper part of the blower circuit, and the electrical wiring with the component parts provided in the outdoor unit is between the power supply units. Although it is convenient that the upper part of the power supply unit is open in order to facilitate the connection of the wiring to the control board, etc. When the oxygen enrichment means like the above technology is arranged on the upper part, the oxygen enrichment means is temporarily removed at the time of maintenance, or the connection part position of the wiring is concentrated on the front surface of the outdoor unit of the power supply part. Design considerations may arise.
[0007]
The present invention has been made in view of such problems of the prior art, and maintains the height and volume of a conventional outdoor unit of an air conditioner, and is suitable for maintaining a high degree of oxygen and maintaining and assembling. It is an object of the present invention to provide a separation-type air conditioner equipped with a unit.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a separation type air conditioner of the present invention comprises an indoor unit and an outdoor unit, and at least one of an oxygen-enriched membrane and an oxygen-enriched membrane that selectively separates oxygen from the air. A separation-type air conditioner having an oxygen enrichment means having a decompression means for decompressing the side of the compressor, wherein the space in which the compressor is arranged and the blower circuit are separated by a partition wall, and the oxygen enrichment The membrane and the decompression means are fixed to the installation member and attached to the outdoor unit, and the air intake surface of the oxygen-enriched membrane is connected to the blower circuit while the installation member is attached to the partition unit on the partition wall. A notch is formed so as to face, and the decompression means is disposed above the compressor inside the outdoor unit.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
The separation type air conditioner according to claim 1 of the present invention is composed of an indoor unit and an outdoor unit, and at least an oxygen-enriched membrane for selectively separating oxygen from the air and one side of the oxygen-enriched membrane. A separation type air conditioner having an oxygen enrichment means having a decompression means for decompressing, wherein a space in which the compressor is disposed and a blower circuit are separated by a partition, and the oxygen enrichment film and the decompression The means is fixed to the installation member and attached to the outdoor unit, and the partition wall is attached to the outdoor unit so that the intake surface of the oxygen-enriched membrane faces the air blowing circuit. A notch is formed, and the pressure reducing means is disposed above the compressor in the outdoor unit.
[0010]
According to this configuration, the oxygen enrichment means can be incorporated in the outdoor unit without significantly changing the configuration of the power supply unit from the conventional one, so that the assemblability of the outdoor unit is not impaired. In addition, since the oxygen enrichment means can be disposed with the outdoor unit having a volume approximately the same as that of the conventional unit, the apparatus can be made compact. In addition, since the power supply unit is substantially adjacent to the power supply unit, it is easy to route the wiring from the oxygen-enriching means. Furthermore, since the unit can be configured integrally as an oxygen enrichment means and attached to the main body, the assemblability is improved. Then, the nitrogen-enriched air that can stay on the primary side ( upstream side ) of the oxygen-enriched film is scavenged so that the efficiency of oxygen enrichment is not reduced as much as possible.
[0011]
The separation type air conditioner according to claim 2 of the present invention is characterized in that the pressure reducing means is arranged so as to be able to ventilate from the space in which the compressor is arranged. According to this configuration, for example, when the outdoor unit is exposed to a low temperature state in winter and the decompression means is also at a low temperature, the load may increase at the time of startup, but the space where the compressor is arranged Since the pressure reducing means is operated for a while after the compressor is operated, the housing temperature is also slightly increased by receiving some heat generated by the compressor. It becomes easy to start.
[0012]
The separation type air conditioner according to claim 3 of the present invention is characterized in that the decompression means is fixed to an installation member configured to be detachable from the outdoor unit. Thereby, the maintainability of the decompression means and the mounting property in the outdoor unit are improved, and the upper structure can be easily removed even when maintaining the compressor located in the lower part.
[0013]
In the separation type air conditioner according to claim 4 of the present invention, the space in which the compressor is disposed and the blower circuit are separated by a partition wall, and the oxygen-enriched membrane and the pressure reducing means are fixed to the installation member. In addition to being attached to the outdoor unit, the partition wall is formed with a communication hole so that the intake surface of the oxygen-enriched membrane faces the blower circuit in a state where the installation member is attached to the outdoor unit.
[0014]
