Independently-circulating explosion-proof air conditioning system and control method

Abstract

The invention discloses an independently-circulating explosion-proof air conditioning system and a control method. The air conditioning system is matched with a closed room without air convection withthe outside, the independently-circulating explosion-proof air conditioning system comprises an air conditioning device, a purifying device, a monitoring device and an explosion-proof device, and theair conditioning device comprises an air conditioning unit, an air pipe, an air inlet and an air outlet. The purifying device and the explosion-proof device are arranged on the air pipe, and the monitoring device is in signal connection with the air conditioning device, the purifying device and the explosion-proof device. The air conditioning system does not communicate with the outside and formsan independent circulating closed circulating system with the sealed room, the temperature and humidity adjusting function is achieved under the condition that it is guaranteed that the production environment is closed, an explosion-proof gas storage bin is arranged, when the oxygen content in the closed environment is higher than the required value, explosion-proof gas is filled into the environment for protection, and the explosion-proof effect is achieved. A purification bypass channel is additionally arranged, so that the purification efficiency is improved when the purification pressureis high, it is guaranteed that the explosive content is lower than a required value, and the production safety is guaranteed.

Description

technical field [0001] The invention relates to the field of industrial explosion-proof technology, in particular to an independent circulation explosion-proof air-conditioning system and a control method. 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 humid...

[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
