As a supplement to thermal cameras, a sniffer system with alarm, can be installed, to monitor small gas leaks from battery in early stage of overheating.
If one of the cameras triggers alarm due to rising temperature, a person with an infrared thermal handgun will be sent to the scene for closer monitoring of the situation. This will only be done if evaluated to be safe.
If the situation escalates into an fire scene:
- Sprinkler system on car deck will be started.
- If possible start to ventilate the smoke out of the car deck.
- Remote operated Brine inject system procedure will start.
The closed circuit comprises a compressor 30 which compresses the ammonia which hereby increases the temperature of the ammonia.
The heated vapor ammonia enters a cold condenser 32 which absorbs the heat from the ammonia which is converted into liquid. The condenser 32 is preferably connected to a cooling tower (not shown) which water cools the condenser.
The liquid ammonia enters a receiver where it accumulates, in order to deliver a continues amount of ammonia to the following components. After the receiver, the high-pressure liquid ammonia enters an expansion valve 36 where it expands, and the pressure decreases whereby the temperature falls and the ammonia is a very cold liquid.
The liquid and very cold ammonia then enters the evaporator 38 where the refrigerant effect occurs. The evaporator 38 is connected to the tank 12 by conduits, such that the brine 22, which is stored inside the tank 12 can be pumped, by a pump 40, through the evaporator 38 where the brine is cooled down to the desired temperature. Preferably, the pump 40 continuously pumps the brine through the evaporator 38 to keep a constant cold temperature of the brine inside the tank 12.
From the tank 12, the brine 22 is delivered to the car (not shown) through the delivery system, which in the shown embodiment is illustrated by the second flexible delivery system 18. The delivery system may consist only of the second flexible delivery system 18.
The diagram shows a cooling system for cooling the brine. The illustrated cooling system is one possible embodiment but it should be understood that the cooling system may be arranged differently.
The system comprises a closed circuit having a refrigerant such as NH3 (ammonia). The system is not limited to ammonia, it may use any freezing method like e.g. CO2.
Alternatively, the second flexible part may be coupled directly to the storage medium for delivering to the fire extinguishing medium without using the first stationary part. It is hereby achieved that the system can deliver fire extinguishing medium outside the area of the first stationary part.
The idea includes the option, that the tank can be disconnected from the cooling unit. This option makes it possible for the fire departments to be better equipped, in case of a “fire” in electrical cars.
