A control method of explosion-proof air-conditioning system with independent circulation

Abstract

The invention discloses a control method of an independent circulation explosion-proof air-conditioning system. The air-conditioning system cooperates with a closed room without air convection with the outside world, and includes an air-conditioning device, a purification device, a monitoring device and an explosion-proof device. The air-conditioning device includes an air-conditioning unit, The air duct, the air inlet and the air outlet, the purification device and the explosion-proof device are arranged on the air duct, and the monitoring device is respectively connected with the air-conditioning device, the purification device and the explosion-proof device. The air-conditioning system is not connected to the outside world, and forms a closed circulation system with independent circulation with the sealed room. The function of temperature regulation and humidity adjustment is realized under the closed production environment, and an explosion-proof gas storage bin is set up. The oxygen content in the closed environment is higher than the requirement. When the value is high, the environment is filled with explosion-proof gas for protection, which plays an anti-explosion role. A purification bypass channel is added to enhance the purification efficiency when the purification pressure is high, to ensure that the content of explosives is lower than the required value, and to ensure production safety.

Description

technical field [0001] The invention relates to the field of industrial explosion-proof technology, in particular to a control method for an independent cycle explosion-proof air-conditioning system. Background technique [0002] Existing air-conditioning air systems generally use air as the cooling and heat transport medium, use fans as the power delivery device, and send the regulated air into the room through filtering devices, surface cooling and heating coils and other equipment to achieve the purpose of temperature regulation. [0003] However, in industrial production, there will be some environments that usually have explosion-proof requirements for production work. These environments will produce explosive gases or explosive dust during production, and some environments with explosion-proof requirements are in contact with the outside world. Closed environment without connection. In this environment, if the production environment requires temperature and humidity, i...

[0003] However, in industrial production, there will be some environments that usually have explosion-proof requirements for production work. These environments will produce explosive gases or explosive dust during production, and some environments with explosion-proof requirements are in contact with the outside world. Closed environment without connection. In this environment, if the production environment requires temperature and humidity, it is necessary to use an air conditioning system to adjust the temperature. The DC air conditioning system is usually used. When there are explosives in the room, this type of air conditioning system Circulating air cannot be processed and must be set as a DC system. If there is a need to adjust the indoor temperature and humidity at this time, it is necessary to cool down, dehumidify, heat or humidify the fresh air. At this time, the operation of the air conditioning system consumes a lot of energy. As well as increasing the capacity of cooling and heating equipment, the cost is relatively high, and it cannot adapt to different operating conditions and cannot cope with many emergencies
