Should You Use Hot or Cold Air to Defog in Summer?

[VonGarrett]

Both cold and hot air are equally effective for defogging, but using cold air is more comfortable in summer while hot air is preferable in winter. Here's an introduction to automotive air conditioning systems: 1. Introduction: The automotive air conditioning system is a device that cools, heats, ventilates, and purifies the air inside the vehicle compartment. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety. 2. Classification by Drive Method: Divided into independent type (uses a dedicated engine to drive the compressor, offering large cooling capacity and stable operation, but with higher costs, larger size and weight, mostly used in large and medium-sized buses) and non-independent type (the air conditioning compressor is driven by the vehicle engine, with cooling performance significantly affected by engine operation, less stable, mostly used in small buses and cars).
