COMPACT COOLING AND EXTINGUISHING SYSTEM

Abstract

The compact cooling and extinguishing system is designed to be placed in a protected device, in particular an electrical switchboard with a DIN rail, wherein the compact automatic cooling and extinguishing system consists of a carrier (14) located inside a pressurized cooling and extinguishing medium, wherein the medium is based on chemical extinguishing agents which are characterized by their temperature during initiation, upon exiting the carrier, being in negative values, i.e.temperature below 0° C, below the reference freezing point, the system is additionally provided with a pressure indicator for monitoring the state of the cooling and extinguishing medium, wherein the compact cooling and extinguishing system is additionally equipped with a first temperature, pressure or smoke switch (15) and a valve (5) which is connected to the coolant carrier and the extinguishing medium by a connection (18), wherein the valve is additionally equipped with a nozzle (6) for releasing the cooling and extinguishing medium into the protected device space, and the valve (6) is further connected to a relay (7). The system has an external power supply (13). The first switch (4) is arranged to open the valve (5) when the temperature setpoint is reached in the protected device. In a preferred embodiment, the compact cooling and extinguishing system is equipped with a compact cover (2) for mounting on a DIN rail.The compact cooling and extinguishing system is designed to be arranged in a protected device, in particular electrical switchboards with a DIN rail, wherein the compact automatic cooling and extinguishing system consists of a carrier (14) containing inside a pressurized cooling and extinguishing medium, wherein the medium is based on chemical extinguishing agents, which are characterized in that during initiation their temperature, when escaping the carrier, is in negative values, i.e.temperature below O °C, below the freezing reference point, the system is further provided with a pressure indicator for monitoring the condition of the cooling and extinguishing medium, wherein the compact cooling and extinguishing system is further provided with a first temperature, pressure or smoke switch (15) and a valve (5), which is connected to the carrier of the cooling and extinguishing medium by connection (18), wherein the valve is further provided with a nozzle (6) for release of the cooling and extinguishing medium into the space of the protected device and the valve (6) is further connected to the relay (7). The system is provided with an external power supply (13). The first switch (4) is set to open the valve (5) when the given temperature value is reached in the protected device. In a preferred embodiment, the compact cooling and extinguishing system is provided with a compact cover (2) for mounting on a DIN rail.
