ANTI-EXPLOSION POSITIVE PRESSURE AIR SUPPLY AIR CONDITIONING DEVICE FOR DRILLER ROOM

摘要

Disclosed is an anti-explosion positive pressure air supply air conditioning device for a driller room, comprising a host refrigeration system, an internal air circulation channel, an air exhaust channel, a positive pressure detection and control system, and a control system (31). The host refrigeration system is a dual system. The internal air circulation channel comprises an air processing channel (15), an air returning channel (22) and an air supplying channel (21). The air exhaust channel (27) comprises a decompression air valve (29) and a switching air valve (28). The positive pressure detection and control system comprises a differential pressure gauge (25) and a communication pipe (26). The control system (31) is used for controlling the temperature and the positive pressure inside the room so as to meet anti-explosion requirements.
