1.8 HEATER FLOW CYCLE
Heating circuit components furnished by Carrier
Transicold include heater cores and evaporator heat
valves for each evaporator assembly. Components
furnished by the bus manufacturer include auxiliary
heater and engine water pumps. The controller
automatically controls the heat valves during heating and
reheat cycles to maintain required temperatures inside
the bus. Engine coolant (glycol solution) is circulated
through the heating circuit by the engine and auxiliary
water pumps. When the evaporator heat valve solenoid
is energized, the valve will open to allow engine coolant to
flow through the heater coil (see Figure 1-4). The valve is
normally closed so that if a failure occurs, it will be able to
cool.
