The function of the evaporator in a car's air conditioning system is to exchange heat with the outside air, absorbing heat through liquefaction to achieve a cooling effect. The evaporator is a component within the air conditioning system where high-pressure liquid refrigerant passes through the expansion valve into the evaporator. The atomization by the expansion valve turns the liquid refrigerant into a mist, which then transforms into a gaseous state under low-pressure conditions. During this transformation process, it absorbs heat from the air, turning it into cool air, thereby achieving the cooling effect. The car air conditioning system is designed to cool, heat, ventilate, and purify the air inside the vehicle cabin, providing a comfortable environment for passengers.

How to Use Lights When Driving at Night?

When driving at night, the correct use of lights is as follows: 1. When meeting another vehicle, switch to low beam when the oncoming vehicle is more than 150 meters away. Use low beam when meeting non-motorized vehicles on narrow roads or bridges. 2. When driving at night without streetlights, poor illumination, or in low visibility conditions such as fog, rain, snow, dust, or hail, turn on the headlights, position lights, and tail lights. 3. When passing sharp curves, slopes, arched bridges, pedestrian crossings, or intersections without traffic lights at night, alternately use high and low beams to signal. 4. When turning left, turn from the left side near the center of the intersection, activate the turn signal, and use low beam when driving at night.

Should You Use Hot or Cold Air to Defog the Car in Winter?

In winter, both hot and cold air can be used to defog the car. The fogging inside the car is caused by the condensation of moisture in the car when it meets the relatively cold glass. A common method is to turn on the air conditioning and blow cold air directly onto the front windshield. The cold air quickly disperses the fog, providing a fast and direct effect. Alternatively, using warm air can dry out the fog, and if the interior of the car is relatively dry, it can prevent the windows from fogging up again for a long time. For regular car use, it is recommended that owners periodically clean the air conditioning system. Prolonged use of the air conditioning system can lead to the breeding of many bacteria inside, which can affect human health if not cleaned for a long time. When cleaning the air conditioning system, it is necessary to visit a professional shop and use formal cleaning agents for the process.
