Guests are most focused on the cleanliness of the tableware they use and any odours inside the restaurant. They are also concerned about any odours around the chairs and tables where they want to enjoy their meal. Whereas owners tend to be concerned about the cleanliness of the restaurant entrance and surroundings, guests may not share this concern. The best way to enhance customer satisfaction is to resolve odours inside the restaurant.

Results
Odour sensor readings in the room tended to decrease when the nanoe™ X device was operated compared to when it was not operated. When the nanoe™ X device was not operated, the distinct odour of the room was apparent when entering the room, but when the nanoe™ X device was operated, it was not apparent.

Conclusion
When a nanoe™ X device is operated, odour reduction in the room can be expected.

Internal verification
Tested product: CS-P45U4B 4-way cassette air conditioner equipped with nanoe™ X (2 units). Evaluation: October 8, 2019, to October 17, 2019. (1) Verification was performed with the unit installed in a conference room of approximately 47 m². (2) Air conditioner settings: operation mode—cooling; preset temperature—27°C; airflow direction—horizontal; airflow speed— medium (3) Operated nanoe™ X device during the first week, then left nanoe™ X device off during the second week, then operated the air conditioner. Measured the odour intensity for 2 days each with an electric odour sensor (XP-329m) made by New Cosmos Electric Co., Ltd. (4) The air conditioner was operated for 24 hours and verified. Target: Room odour

Odour intensity levels
0 Odourless
1 Hardly noticeable
2 Minimally identifiable
3 Immediately noticeable
4 Strong
5 Intensely disagreeable

Results
After 2 hours there was an odour intensity reduction of approximately 0.7 level more with nanoe™ X than with natural reduction.

(Report No. 27055)

Tested product: 4-way cassette air conditioner equipped with nanoe™ X. Test method: (1) The test air conditioner was installed inside a test chamber measuring approximately 6.02 m x 8 m x 2.9 m, or about 48 m². (2) A predetermined number of pieces of cloth (gauze) were hung in an approximately 1 m³ box and 20 cigarettes were lit and left for five minutes. (3) The pieces of cloth that had absorbed the cigarette smoke odour were placed at a height of less than 1.2 m approximately 1.5 m away from the air conditioner outlet and the air conditioner was operated in fan mode. (4) The pieces of cloth were collected after a predetermined period and a sensory evaluation was implemented (6-level odour intensity indication method). N = 8 subjects. Target odour: Cigarette smoke.
