What is the use of Toyota Highlander heating and air conditioning system accessories?

According to its functions, the air conditioning system of GAC Toyota Highlander can be divided into several main components, such as refrigeration system, heating system, ventilation and air purification system and control system. The main components are condenser, air-conditioning pump, air-conditioning control panel, warm air water tank, air-conditioning filter screen, water tank, air-conditioning radiator, drying bottle, air conditioner, pump pulley, air-conditioning compressor, warm air motor, air-conditioning pipe (evaporator-air-conditioning pump), blower motor, front heater and air conditioner. Compressor bearing, electromagnetic coil of air-conditioning pump clutch, air-conditioning controller, heater resistor, air-conditioning switch, dryer, evaporator assembly, air-conditioning pipe (air-conditioning pump-condenser), blower electrical and mechanical resistor, blower resistor, air-conditioning grille (air-conditioning filter), turbocharger, evaporator core, expansion valve, air-conditioning pump clutch, air-conditioning pressure switch, compressor, condenser electronic fan assembly and evaporation box assembly. Blower assembly, etc. The refrigeration system of GAC Toyota Highlander adopts the principle of vapor compression refrigeration to cool or dehumidify the air inside the car or the fresh air entering the car from the outside, so that the air inside the car becomes comfortable. The heating system adopts hot water heating device, and the engine cooling water is used to heat the air in the car or the fresh air from the outside, so as to achieve the purpose of heating and dehumidification. You can also defrost and defog the front windshield in winter. The centrifugal blower of the ventilation device sucks fresh air from the outside into the car to replace the air in the car, thus achieving the effects of refrigeration, heating and ventilation. Besides the blower, the ventilation device also has a filter, an air inlet, an air duct and an air outlet. The air purification system removes the dust smell in the air inside the car and makes the air clean. The simple way is to install a dust filter in the vent. Advanced cars are also equipped with air quality sensors. When the air quality is poor, the air flow after preliminary filtration will be further purified through the activated carbon valve. When the air temperature is cold, the humidifying device humidifies the air inside the car to make the relative humidity of the air inside the car reach 40%-50%. Manipulation and control system This system is mainly composed of electrical components, vacuum mechanism and manipulation mechanism. On the one hand, the temperature and pressure of refrigeration system and heating system are safely controlled and protected, and at the same time, the air temperature, air volume and air outlet direction in the car are controlled. Automatic air conditioning system refers to the automation of control system.
