Mounted to the side of the locomotive, this air conditioning system (ACU) supplies 8kW cooling to ensure a cabin temperature of 22°C-25°C max in a 45°C ambient, provided the cabin is thermally insulated. The aircon is a single evaporator design with a single horizontal scroll compressor.
The ACU system does not restrict the standard operational features of the locomotive. The system is designed to be removed from the locomotive within ten minutes with the use of an overhead crane. This ensures quick turnaround times when the system needs to be replaced.
The electrical connections, looms between the aircon, power units, electronic control panels and electrical control gear are designed and selected for operation in the Railway environment, which include adverse temperatures as well as severe shock and vibration.
The aircon is hard wired with no complex electronics or intelligent control. The system can only be switched on and off with 2 fan speed options. The system can however as an option be supplied with an electronic controller which allows Bluetooth login interface and monitoring via smartphone app and/or laptop.
SME can package this system, within limits, in an enclosure which would fit the client’s requirements.
