Water heating heating system The heat source comes from the engine coolant. The water heating heating system is mostly used in cars, large trucks and buses with low heating requirements. Water heating heating system is mainly composed of heater, hot water regulating valve, blower, control panel, etc. Among them, the blower is composed of DC motor with adjustable speed and squirrel cage fan. Its function is to blow cold air to the heater. After heating, the cold air is sent into the vehicle. Adjusting the speed of the motor can adjust the air supply to the compartment. Air heating system The heat source comes from the engine exhaust system. Air heated heating system is mostly used in air-cooled engine vehicles. Heat exchanger heating system: when heating, the exhaust valve 4 is turned to the position shown in Figure 2, the hot air in the exhaust pipe is introduced into the heat exchanger 5, and the cold air blown by the blower absorbs the heat after the heat exchanger and is introduced into the vehicle for heating or defrosting. Heat pipe heating system: the heat pipe heat exchanger is vertically installed in the floor of the carriage. The condensation and heat release section is above the floor and the exhaust gas heating section is below the floor. The exhaust gas discharged from the exhaust pipe of the automobile engine is introduced into the heat pipe exchanger, which is equipped with liquid ammonia. After being heated, the liquid ammonia vaporizes and rises to the upper part of the heat pipe exchanger for heat exchange with the air to heat the air coming in from the vent. After the air is heated, it is blown into the compartment by the blower for heating. Once the heat is released, the ammonia condenses and flows back to the lower part, and then completes the next working cycle. Fuel air heating system: a heating system that directly heats air with fuel is called fuel air heating system. Independent combustion heating system The heat source comes from the heat of special fuel combustion. Independent combustion heating system is mostly used on buses. Integrated preheating heating system The heat source comes from the heat of engine coolant and the heat of special fuel combustion device. The integrated preheating heating system is mostly used on buses.
