In this simulation, we created an analysis model that imitated the 9th and 10th floors of the Kawasui building. Based on the results of the droplet analysis that visualized the route and ventilation status of the droplets generated from the human body, we took antibacterial and antiviral measures in the building. In addition to installing an air purifier "Airdog" equipped with a US patented "TPA filter" at the airflow retention point, the effect of inactivating the new coronavirus by photocatalyst and silver ions was confirmed (* 1). We have introduced "Isave Antibacterial CCFL Light", which has anti-virus functions, in the hall. Kawasui will continue to reduce the risk of infection and build a safer and more secure environment by combining various new epidemic prevention efforts. (* 1) Source https://aisave.asia/test/
We created a 3D analysis model based on the 3D scanning point cloud data of the target location, and simulated the diffusion status of droplet particles generated from the human body and the purification status of air. The analysis contents were (1) indoor temperature and air flow field, (2) indoor air purification degree, and (3) splash diffusion analysis, and steady and unsteady analysis was carried out for 40 minutes in real time. [Analysis details] (1) Conducted indoor temperature and air flow field / steady analysis (analyzed by defining it as not changing with the passage of time) (2) Degree of purification of indoor air-Based on the calculation results of (1), pollutants Calculation of the process of purification by air conditioning ・ Analysis of the transition for 40 minutes as unsteady analysis (analyzed by defining it as fluctuating with the passage of time) ・ The pollutant is a passive scalar (the pollutant itself does not affect the flow field) ) ・ Definition ・ After calculation in the current environment, the purification effect after installing the air purifier is also verified by simulation ③Splash diffusion ・ Based on the calculation result of ①, the splash diffusion path is calculated ・ 40 minutes as unsteady analysis (Assuming that the splash generation time is about the first 10 seconds) ・ Visualize the diffusion path at each particle size
Kawasui is the first aquarium to carry out airflow and splash simulations using the "3D splash visualization system" so that customers can enjoy the building safely and securely. Analysis video: https://www.youtube.com/watch?v=qFfP_tADOU4 "3D splash visualization system" visualizes the place where the air in the hall is stagnant. It was confirmed that the air was replaced once every 10 to 15 minutes. (Excluding some zones out of all 6 zones of Kawasui) The result was that measures such as an air purifier were required for the zones where the purification level value did not improve after 40 minutes had passed. Based on the above results, we will take measures against the air retention point for further purification of the air in the building. Antibacterial and anti-virus measures based on the analysis results . High-performance air purifiers "Airdog X5s" and "Airdog X8 pro" are installed in the zone where there is no change, and they have functions such as anti-virus by photocatalyst and silver ion. We have introduced "Antibacterial CCFL Light" and "WARP Air" with built-in "Eye Save Antibacterial CCFL Light". Installation location: 10F Ticket Counter, 10F Tama River Zone, 10F Kawasui Hall 10F Restaurant AOW, 9F Komorebi Cafe ~ Sweets & Cafe ~▲ "Airdog X5s" installation image

As a result of verification, diffused substances such as viruses and droplets are replaced once every 10 to 15 minutes by air conditioning at the restaurant AOW on the 10th floor of Kawasui and the Komorebi Cafe on the 9th floor so that you can spend your time safely and securely at restaurants. I was able to confirm that. However, in addition to the infectious disease spread prevention measures that we have taken so far, "I Save Antibacterial CCFL Light" is placed on the buffet table and in the seating space so that visitors can spend their time at the restaurant even more safely and securely. , And also installed "Airdog X5s" in the store, and took additional measures.▲ Image of setting up Komorebi Cafe

The "Airdog X5s" and "Airdog X8 pro" are air purifiers equipped with the proprietary technology "TPA filter" developed in Silicon Valley, which has been patented in the United States (US patent number: US9868123B2 / US9735568B2). "TPA filter" is a filter that charges harmful substances with positive ions by creating an electromagnetic field and adsorbs dirt like a magnet. This removes 99.8% or more * 1 of fine particles of 0.0146 μm, which are finer than 1/6 of the virus. Currently, it has been introduced in more than 10,000 medical institutions and educational facilities nationwide, as well as the Imperial Household Agency and space-related business facilities.

Airdog Official Homepage: https://airdogjapan.com Eye Save Antibacterial CCFL Light is a type of fluorescent lamp called Cold Cathode Fluorescent Lamp (CCFL). It is an epoch-making lighting fixture that can sterilize, antibacterial, deodorize, and prevent molds such as airborne bacteria, molds, and viruses by the action of the photocatalyst and silver ions (Ag +) that are generated just by lighting. WARP Air is a space sterilization lighting device that maximizes the effect of eye save. The same laminar flow process as in a sterile operating room, maximizing the effect of eye save, photocatalytic effect and releasing charged silver ions into the space are effective for space sterilization.

Eye Save Antibacterial CCFL Light / WARP Air Official Homepage https://aisave.asia/ * Eye Save Antibacterial CCFL Light does not completely prevent virus infection. Kawasui is operating with the following measures to prevent infection with the new coronavirus. Video URL that summarizes infection prevention measures in the Kawasui building: https://youtu.be/c-V470XxFYo ● Requests to customers 〇 Wearing a mask * Excluding children under 3 years old 〇 Ensuring intervals between customers 〇 Transfer of money using coin trays ● Efforts at facilities in the building 〇 Restrictions on admission during congestion 〇 Prevention of droplet infection at the counter / cash register 〇 Ventilation / cleaning / sterilization in the building 〇 Temperature measurement with a thermography camera at the time of admission 〇 Admission Occasionally thorough hand disinfection 〇 Antibacterial and anti-virus treatment with air catalyst 〇 Air circulation in the building with air purifier “Airdog” 〇 Antibacterial anti-virus treatment with “eye save antibacterial CCFL light” ・ Antibacterial with silver ions ● Kawasui crew's efforts 〇 Wearing a mask 〇 Daily temperature measurement / physical condition management 〇 Thorough garment / hand washing / sterilization ● Introduction of “congestion lamp” We have introduced a “congestion lamp” service that notifies customers of the congestion status in the building in real time. We will deliver the congestion status of 3 stages of "vacant", "slightly crowded" and "crowded" in real time on the official website and Kawasui app. For details, please refer to the Kawasui official website.
