Claims (20)

  1. An air shower system that has a function to determine the number of people entering the room, and adjusts the airflow, duration, or both of the air shower's fan based on the result of this determination.
  2. The air shower according to claim 1, which has a function to notify the number of people allowed to enter the room.
  3. The notification function uses one of the following: numbers, colors, lights, images, pictograms, or sounds. (Air shower according to claim 2)
  4. The air shower according to claim 1, wherein the number of people entering the room is determined by using either an actual measurement, the number of air shower users per unit time, or the air shower operating time per unit time.
  5. The aforementioned determination is made based on whether the value is greater than or less than a specified value, as described in claim 1 of the air shower.
  6. The air shower according to claim 5, wherein if the number of people entering the room exceeds the specified value, the airflow of the air shower fan is increased, the duration is extended, or both are performed.
  7. The air shower according to claim 5, wherein if the number of people entering the room falls below the specified value, the airflow of the air shower fan is reduced, the duration is shortened, or both are performed.
  8. The air shower according to claim 1, wherein the determination of the number of people entering the room is performed using one of the following methods: person identification using a camera, person identification using an infrared sensor, person identification using an ID authentication function, or person identification by weight.
  9. The air shower according to claim 5, wherein the aforementioned specified value is determined per unit time.
  10. The air shower according to claim 9, wherein the aforementioned specified value is set by referring to past specified value information.
  11. The air shower according to claim 9, which overwrites the registered default value information if the value exceeds or falls below the aforementioned default value.
  12. The air shower according to claim 10, which schedules and manages the aforementioned specified value.
  13. The air shower according to claim 12, wherein the aforementioned specified value can be set from an external monitoring device via a communication line.
  14. The air shower according to claim 12, wherein the aforementioned specified value is set based on the specified value information for each time period of the previous day.
  15. The air shower according to claim 12, wherein the specified value is set based on the specified value information for each time period of the previous week.
  16. The air shower according to claim 4, wherein, instead of the number of people entering the room, X1 is the cumulative air jet operating time per unit time for each time period in the past, and Y1 is the average cumulative air jet operating time per unit time in the past, and for time periods when X1 exceeds Y1, multiple people are allowed to pass through, and the airflow of the air shower fan is increased, or the duration is extended, or both.
  17. The air shower according to claim 16, wherein the determination of the time period in which X1 exceeds Y1 is made by comparing it with a value obtained by adding a constant to or multiplying Y1 by a constant, and then reversing the result.
  18. The air shower according to claim 16, wherein the settings for the air jets for each time period are created in advance using the aforementioned X1 and Y1.
  19. The air shower according to claim 18, wherein during the time period when multiple people are passing through, the fact that multiple people can enter is notified using one of the following: numbers, colors, lights, images, pictograms, or sounds.
  20. The air shower according to claim 19, wherein X2 measures the cumulative air jet operating time per unit time for each time period, and Y2 calculates the average cumulative air jet operating time per unit time based on X2, and one or both of X2 and Y2 can be set as a new X1 or Y1.
