When crew module needs heating, when the water temperature that cooling-water temperature sensor 6 is detected is less than 45 DEG C, electric heater 10 and electricity
Sub- water pump 11 is run, and air blower 15 is opened, and crew module is heated；Meanwhile, the A mouths of triple valve 4 and C mouthfuls of conductings, dynamical system
The cooling water of system is circulated by second heat exchanger 14.When the water temperature that cooling-water temperature sensor 6 is detected is higher than 45 DEG C, close
Electronic water pump 11 and electric heater 10 in PTC HVACs loop, the cooling water of dynamical system still all flow through the second heat exchange
Device 14, and by the rotating speed of electronic water pump 18, to adjust the heat that dynamical system is delivered to crew module, maintain crew module's temperature.
When the constant temperature of power system components rises, when the temperature of cooling-water temperature sensor 6 is higher than 55 DEG C, then by triple valve
A, B, C mouthfuls all turn on, and part coolant is flowed through radiator 16, reduce the temperature of dynamical system.When the temperature of cooling-water temperature sensor 6
When degree drops to 55 DEG C, the radiating of radiator can't be stopped immediately, but persistently radiated, until the temperature of cooling-water temperature sensor 6
When dropping to 50 DEG C, then by the A mouths of triple valve and C mouthfuls of conductings, and close cooling fan.The used heat of dynamical system again will be completely sharp
Use in crew module's heating.This measure is to prevent the frequent movement of triple valve 4 and cooling fan 17, extend it and use the longevity
Life.
