Problems solved by technology

[0007] However, in the conventional oxygen enrichment device described above, if the sending passage of the oxygen-enriched air is exposed to the low-temperature outdoor air, there is a problem that the dew condensation water freezes inside the sending passage and blocks the flow passage. Oxygen-enriched air cannot be sufficiently delivered to the room
[0008] In addition, if dew condensation water is generated in the delivery path, there is also a problem that the flow of the enriched air may cause air vibration or cracking sound, which propagates to the indoor side where the user lives, giving the user an uncomfortable feeling.
[0009] In addition, if the dew condensation water flows into the decompression pump as the enriched air delivery device in the oxygen enrichment device, there is also a problem that while the service life of the pump parts is greatly affected, if the decompression pump A large amount of condensation water is compressed, and the compression mechanism will be damaged due to liquid compression

Embodiment approach 1

[0018] Regarding the oxygen enrichment device and the air conditioner in Embodiment 1 of the present invention, refer to figure 1 described as follows. The air conditioner 1 is composed of an indoor unit 11 arranged in an indoor space as a first space and an outdoor unit 10 arranged in an outdoor space as a second space; the indoor unit 11 and the outdoor unit 10 are composed of connecting pipes for circulating refrigerant gas. (not shown) is connected. The indoor unit 11 is provided with an indoor fan 13 , an indoor heat exchanger (not shown), and an air outlet 14 . On the other hand, the outdoor unit 10 is provided with a compressor 20 , an outdoor heat exchanger 22 , and an outdoor fan 21 that blows air to the heat exchanger 22 .

[0019] The oxygen enrichment device 30 is composed of a decompression pump 3 built in the indoor unit 11 as a decompression unit and an oxygen enrichment membrane 2 built in the outdoor unit 10 as an oxygen enrichment unit for enriching high-co...

Embodiment approach 2

[0028] Next, regarding the oxygen enrichment device and the air conditioner according to Embodiment 2 of the present invention, refer to figure 2 , 3 Be explained. However, the same reference numerals are assigned to the same structural elements as those in Embodiment 1, and description thereof will be omitted.

[0029] In the embodiment of the present invention, such as figure 2 As shown, the oxygen enrichment device 30 installed in a separate room in the outdoor unit 10 has an oxygen enrichment membrane 2, a decompression pump 3, and a flow passage 4 that can ventilately connect the oxygen enrichment membrane 2 and the decompression pump 3. , At the same time, there is an air introduction pipe 5 branched from the flow path 4 . In addition, a fan (not shown) and the like for removing stagnant nitrogen-enriched air are disposed on the primary side (atmosphere side) of the oxygen-enriched membrane 2 , and these structures are the same as those in the first embodiment. In ...

Abstract

The invention provides an oxygen enrichment device and an air conditioner, comprising an oxygen enrichment membrane for enriching the oxygen concentration, a decompression pump for reducing the pressure on one side of the oxygen enrichment membrane, and connecting the oxygen enrichment membrane and the decompression The flow path of the pump: the decompression pump is arranged on the indoor unit that emits air enriched in oxygen concentration, and at the same time, the oxygen-enriched membrane is arranged on the outdoor unit, thereby depressurizing the flow path and suppressing the generation of condensation water .

Description

technical field [0001] The present invention relates to an oxygen enrichment device which relatively increases the concentration of oxygen in air compared with other gases, and an air conditioner equipped with it. Background technique [0002] In recent years, devices that use gas enrichment mechanisms such as oxygen enrichment devices or nitrogen enrichment devices to relatively increase the concentration of specific gases have been used in equipment such as medical oxygen enrichment devices, air conditioners, and air cleaners. [0003] For example, there is a device in which an oxygen enrichment device for increasing the oxygen concentration is installed in the outdoor unit of a separate air conditioner, and oxygen-enriched air is sent to the indoor unit through a delivery pipe and released to the indoor side, so that it can be used as Oxygen concentrations in rooms using conditioned spaces are increased for occupant comfort. [0004] In the oxygen-enrichment operation us...
