Automotive air conditioning air purification system: the general use of air filters, exhaust vents, electrical dust collectors and anionic generators, etc. Heat load of automobile air conditioning refrigeration system: ventilation heat load, conduction heat load, radiant heat load, occupant heat load Ventilation heat load: In order to ensure that the occupant can breathe fresh air, the car needs a certain amount of ventilation, because there are gaps in doors and Windows, there are also fresh air exposed, will inevitably bring a lot of heat, so that the temperature inside the car rises.
Conduction heat load: Because the temperature inside the car is higher than the air temperature inside the car, solar radiation will also make the body temperature rise, heat must be conducted into the car through the body, Windows and floor, and the heat of the engine compartment is also conducted into the car through the wall. Therefore, it is required that the temperature insulation performance of the car compartment is better to reduce the conduction heat load.
Radiant heat load: The heat of the sun enters the car through the glass window in the form of radiation, and the reflective glass or sunshade film can reduce the power consumption of the engine.
