Problems solved by technology

First, at least on the secondary side of the gas enrichment mechanism, inside the delivery line when the delivery line of the enriched air is exposed to low temperatures (for example, when the delivery line is exposed to the outside atmosphere and the ambient temperature is low), , the dew condensation water freezes when the operation is stopped, and the oxygen-enriched air may not be delivered to the room when the operation is restarted.
Second, even if only dew condensation water is generated in the delivery line, it will become a load when the differential pressure generating mechanism starts, so the differential pressure generating mechanism may not start normally.
In some cases, due to excessive load, there may be cases where the differential pressure generating mechanism does not start smoothly
Third, due to the condensation water generated in the delivery pipeline, when the operation stops, it is easy to produce abnormal sounds like air fluctuations or cracking sounds
In addition, the stop sound of the differential pressure generating mechanism is generated, which gives the user an uncomfortable feeling both indoors and outdoors.

Embodiment approach 1

[0022] First, use figure 1 , figure 2 , image 3 Embodiment 1 will be described. Such as figure 1 As shown, the air conditioner is composed of an indoor unit 11 and an outdoor unit 1, which are connected by connecting pipelines (not shown in the figure) to circulate refrigerant gas. An indoor fan 13 is provided in the indoor unit 11 . On the other hand, the outdoor unit 1 includes a compressor 20 , a heat exchanger 22 , and an outdoor unit fan 21 . Furthermore, an oxygen enrichment membrane is used as a gas enrichment mechanism having a function of increasing the concentration of a predetermined gas component. As a gas enrichment device having an oxygen enrichment film, in this embodiment, an oxygen enrichment device 30 is provided. As the differential pressure generating means, a decompression pump is used. The oxygen enrichment device 30 has: an oxygen enrichment mechanism 2; a diaphragm type decompression pump 3 with a resin diaphragm; the oxygen enrichment mechanis...

Embodiment approach 2

[0036] Second, use Figure 4 , Figure 5 Embodiment 2 will be described.

[0037] Embodiment 1 opens and closes the flow path opening and closing mechanism 8 according to the atmospheric temperature around the decompression pump 3 or the like. In Embodiment 2, the number of driving revolutions is detected as the operating capacity at the time of activation of the instruction differential pressure generating mechanism, and the control device 12 opens and closes the flow path opening and closing mechanism 8 based on the number of revolutions.

[0038] Such as Figure 4 As shown, the rotation speed detection device 16 for detecting the operation state of the decompression pump 3 is arranged. The number of revolutions R detected by the number of revolutions detection device 16 is compared with the number of revolutions R1 set in advance. So, according to Figure 5 The control method shown, as Figure 6 As shown, the opening and closing operation of the flow path opening and ...

Embodiment approach 3

[0040] In Embodiment 3, unlike Embodiments 1 and 2, an electric flow path opening and closing mechanism (not shown in the figure) with a variable opening degree is used as the flow path opening and closing mechanism 8 . The opening degree of the channel opening and closing mechanism can be changed according to the atmospheric temperature, the temperature of the housing of the differential pressure generating mechanism, or the operating capacity. The opening and closing mechanism of the flow path can continuously change the opening degree, and can also adjust the opening degree step by step. For example, when the opening degree of the flow opening and closing mechanism is controlled based on the atmospheric temperature detected by the temperature sensor 10, the lower the atmospheric temperature, the greater the opening degree of the flow opening and closing mechanism to activate the device. In order to blow off at least water droplets that may remain in the air supply passage 4...

Abstract

A gas enrichment apparatus containing gas enrichment means and differential pressure generating means, and an air blowing apparatus, having following advantages: The differential pressure generating means makes a reliable startup, and the apparatus can purge the wet air and the dew drop coming from gas enrichment means out of gas flow channel. For implementing the above advantages, it is provided with control unit which operates flow channel gating means linking with startup of differential pressure generating means. And, flow channel gating means is kept to be open for a certain specific time after instruction to suspend the operation is delivered.

Description

technical field [0001] The present invention relates to a gas enrichment device for increasing the concentration of a predetermined gas in the air relative to other gases and a blower using the device. Background technique [0002] Conventionally, devices that relatively increase a specific gas concentration, such as an oxygen enrichment device and a nitrogen enrichment device using a gas enrichment mechanism, are known. [0003] Among them, there are oxygen enrichment devices for medical use, air conditioners, air cleaners and other equipment. Among them, JP-A-5-113227 discloses an example of increasing the oxygen concentration. The outdoor unit of the split air conditioner is equipped with an oxygen enrichment mechanism, which sends the oxygen-enriched air to the indoor unit through the delivery pipeline, and then releases it to the indoor side. In this way, the oxygen concentration in the room of the air-conditioned space can be increased, giving the occupants a sense o...
