Depending on the coolant temperature monitored by the temperature sensor 9, the following may occur:
1. when the water inlet temperature of the heater 3 is lower (example: 40 ℃), the heated coolant flows out from a water outlet A shown in figures 1, 3 and 4 after passing through the three-way electromagnetic control valve 4 and returns to a water inlet of an engine water pump 15 to rapidly heat the water jacket of the cylinder body of the engine 1, and the coolant does not enter the air heating device 2 at the moment, namely, the coolant is all used for heating the engine 1;
2. when the water inlet temperature of the heater 3 is higher (for example: >40 ℃), the heated coolant passes through the three-way electromagnetic control valve 4 and then flows out from the water outlet B in figures 1, 3 and 4, the high-temperature coolant flows to the compartment heater 2 to heat the passenger compartment or the compartment, the coolant flowing through the heater 2 enters the engine 1 through the hot air outlet pipe 8 and participates in the whole large circulation, namely the coolant at the moment is divided into two lines, one line enters the engine 1 from the heater 3 and then returns to the heater 3 for circulation, and the other line enters the heater 2 from the heater 3 and then enters the engine 1 and then returns to the heater 3 for circulation; even if the engine is not started, the heater 3 can supply heat to the carriage air heater 2, and the practicability of the heater 3 is greatly improved.
