Is done.

When the frost control device 1 is operated, the internal and external air valves 16 are opened to allow the inflow of internal air through the inlet pipe 14.

At this time, the room temperature sensor 60 of the inlet pipe 14 detects the internal air, and detects the external air by the external temperature sensor 62. When the intake air temperature sensor 64 detects the temperature of the internal and external air introduced in this way, The controller 12 recognizes and controls the first motor 20 to control the inflow of air.

In addition, the electronic control apparatus 12 rotates the blower 24 by driving the fan motor 26 to blow air intake air.

When the air pressurized by the blower 24 is below a predetermined temperature, the third motor 34 is driven to block the direct passage 28 and the heating passage 30 is opened. Let's do it.

Air passing through the heating passage 30 is heated by the heater 38 to discharge the warmth.

The heater 38 is connected to the coolant line 36 to be heated by the coolant heated while circulating the engine, and the water temperature sensor 40 is installed in the coolant line 36 to sense the temperature of the coolant. This will detect the warming up of the engine.
