Överlagrat värmesystem för ett lokomotiv

摘要

A layover heating system ( 89 ) for a locomotive is provided. The layover heating system ( 89 ) is adapted to be used in conjunction with a conventional locomotive cooling systems. The layover heating system ( 89 ) includes a water tank and pump ( 90 ). A layover heater ( 92 ) heats fluid in the layover heating system ( 89 ). An orifice ( 98 ) is provided to control the flow Of fluid in the layover system ( 89 ) to generally balance the pressure on either side of the locomotive radiator. In this manner, fluid flow through the radiator is minimized, minimizing heat loss at the radiator. A variable orifice may be used that is adjustable in response to a signal generated from pressure sensors on each side of the radiator and processed by a central processing unit.
