2.4 Purpose of the System / Customer Needs

- The purpose of the system is to increase the indoor oxygen concentration for preventing altitude sickness of tourists who are unfamiliar with the high mountain environment.

- For the urgent need of oxygen, it is possible to inhale 5LPM of oxygen by connecting a cannula on the bottom of the product.

- Once the target oxygen concentration is set, automatic control is possible, and no additional operation of the equipment is needed.

- In addition to the oxygen supply, real-time monitoring of indoor air quality and air cleaning functions have been secured.

3. Installation Information

The hotel equipped with the system is located in Shangri-La, Chinawhere the altitude of the region is 3500m so that the oxygen density is extremely low. (35% lower air density compared tothe average level)

In general, the installation place for an oxygen generator is considered from the early construction stage of the building, but in this case, since the installation was done to the nearly completed hotel building, it was unavoidable to install the device on the rooftop.

 (Shangri-La region of China located on the altitude of 3,500m)

4. Product Effects (quantitative effect) – Increase in the indoor oxygen concentration by 2%

From the test operation of the product after installation, the target oxygen concentration was set by 23%, and the target oxygen concentration was achieved about 2 hours after operating the product from the initial average oxygen concentration of the hotel room which was 20.3%.

It is common that most of the tourists visiting this region from other areas suffer from various symptoms of altitude sickness due to lack of oxygen, but in case of this hotel, it was confirmed that majority of the guests had comfortable relaxation without experiencing any altitude sickness symptoms from the aid of the oxygen generator.

According to a worker from the hotel, this oxygen generator would be able to create a luxurious image of the hotel compared to other hotels around it, and it is also highly satisfactory that such feature can be actively applied to the promotion and marketing of the hotel.
