Title:
LOW OXYGEN ENVIRONMENTAL CONTROL SYSTEM
Document Type and Number:
Japanese Patent JP2020180449
Kind Code:
A
Abstract:
To provide a low-oxygen environment control system which can maintain low oxygen concentration in an indoor environment of a training room or storage room at an arbitrary predetermined oxygen concentration, can be restored to predetermined oxygen concentration in a short time if an abnormal value is measured in the oxygen concentration or carbon dioxide gas concentration, and is safe for human bodies and inexpensive with easy configuration.SOLUTION: A low oxygen environment control system includes: nitrogen gas generating means; a compressor; a flow rate adjusting valve for adjusting a flow rate of nitrogen; oxygen concentration measuring means; carbon dioxide gas concentration measuring means; nitrogen gas concentration measuring means; exhaust means for discharging indoor air; air blowing means for supplying outside air to a room; an air conditioner for circulating the air in the room; and control means. The low oxygen environment control system can solve a problem by: acquiring oxygen concentration information from the oxygen concentration measuring means, carbon dioxide gas concentration information from the carbon dioxide gas concentration measuring means, and nitrogen gas concentration information from the nitrogen gas concentration measuring means; and controlling operations of the nitrogen gas generating means, the compressor, the flow rate adjusting valve, the exhaust means, the air blowing means and the air conditioner by the control means.SELECTED DRAWING: Figure 1
