What does A/C in a car mean?
1 Answers
Car A/C stands for: Car air conditioning device (air conditioning device), abbreviated as A/C. Air conditioning types are divided into the following categories: 1. By driving method: Independent type (driven by a dedicated engine to power the compressor, with large cooling capacity and stable operation, but high cost, large size and weight, mostly used in large and medium-sized buses) and non-independent type (the air conditioning compressor is driven by the car engine, cooling performance is greatly affected by the engine operation, with poor stability, mostly used in small buses and sedans). 2. By air conditioning performance: Single-function type (separate installation of cooling, heating, and ventilation systems, operated independently without interference, mostly used in large buses and trucks) and integrated heating and cooling type (cooling, heating, and ventilation share a blower and air duct, controlled on the same panel, which can be divided into combined type where heating and cooling work separately and mixed temperature adjustment type where heating and cooling can work simultaneously. Sedans mostly use the mixed temperature adjustment type). 3. By control method: Manual type (adjust temperature, wind speed, and direction by toggling function keys on the control panel) and electronically controlled pneumatic adjustment (using vacuum control mechanisms, when the air conditioning function key is selected, temperature and air volume can be automatically controlled within the preset range). 4. By adjustment method: Fully automatic adjustment (using calculation and comparison circuits, controlling adjustment mechanisms through sensor signals and preset signals to automatically adjust temperature and air volume) and fully automatic adjustment controlled by microcomputer (using a microcomputer as the control center to achieve comprehensive and multifunctional optimal control and adjustment of the in-car air environment).
