Title:
SYSTEM AND METHOD FOR RECOVERING FIRE-EXTINGUISHING AGENT
Document Type and Number:
WIPO Patent Application WO/2013/180520
Kind Code:
A1
Abstract:
The present invention provides a system for recovering a fire-extinguishing agent, comprising: a cooling system for receiving the fire-extinguishing agent stored in a cylinder and lowering the temperature and pressure of the fire-extinguishing agent to below those of the fire-extinguishing agent when it was stored in the cylinder, cooling system including a heat exchanger and a compressor; a storage tank connected to the cooling system so as to recover the lower-temperature, lower-pressure fire-extinguishing agent from the cooling system and storing the fire-extinguishing agent; a sensor unit for sensing the temperature of the cooling system and the temperature and pressure of the storage tank; and a control panel for controlling the operation of the cooling system on the basis of the signal sensed by the sensor unit. The liquid fire-extinguishing agent stored in the cylinder is fed to the heat exchanger by means of a pressure difference occurring when the cooling system operates so as to maintain the evaporative temperature of the heat exchanger at a level lower than a preset level, and then the temperature and pressure of the fire-extinguishing agent is lowered below those of the fire-extinguishing agent when it was stored in the cylinder, and the fire-extinguishing agent is recovered in the storage tank.
