What is the function of the evaporator in a car air conditioning refrigeration system?

Car air conditioning evaporators are effective in cooling the interior of the vehicle. Below is more information about interior cooling: 1. The evaporator is a heat exchanger. High-pressure liquid refrigerant enters the evaporator through the expansion valve. Due to the atomization effect of the expansion valve, the liquid refrigerant turns into a mist, which then transforms into a gaseous state under low-pressure conditions. During this transformation process, heat is absorbed, making the evaporator very cold. When air passes through it, it turns into cool air, achieving the purpose of refrigeration. 2. Evaporators come in tube-fin, tube-belt, and laminated types. Currently, passenger cars in China mainly use all-aluminum laminated and tube-belt evaporators, while large buses primarily use copper tube-aluminum fin evaporators. Medium-sized buses may use any of these types, with tube-belt being the most common. The refrigerant channels in air conditioning heat dissipation evaporators are formed by two aluminum plates stamped into complex shapes, layered together to create sandwich plates that form the refrigerant channels. Between every two sandwich plates, corrugated heat dissipation strips are placed, and these layers are stacked together, providing excellent heat dissipation effects. 3. The air conditioning evaporator is located inside the evaporator box, which is inside the dashboard, usually in the middle of the dashboard. It is connected by nothing more than high-pressure and low-pressure pipes. It is important to ensure that the sealing rings are properly installed. The evaporator has a long service life and can generally last until the car is scrapped.

What is the Chinese meaning of 'service' in vehicles?

The 'service' indicator on a vehicle signifies that the car requires maintenance. Here is more information about 'service': 1. When a car reaches a certain mileage, the 'service' indicator or a small wrench symbol will appear on the dashboard to remind the user that the vehicle needs inspection or replacement of certain worn parts. 2. Generally, car manufacturers specify maintenance intervals within certain mileage ranges, commonly at 5,000, 7,500, or 10,000 kilometers. Following the maintenance schedule outlined in the owner's manual is highly recommended as it is very reasonable. Therefore, it is advisable to perform each maintenance item as specified in the manual. 3. Different cars have different dashboard designs, but common gauges include the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, and charging gauge.

What does it mean when the Volkswagen EPC light comes on?

There are two possible reasons for the EPC light to come on. 1. The throttle body is dirty and needs cleaning. 2. The brake lights are not working, requiring inspection of the brake switch and wiring. 3. The EPC warning light may also illuminate due to fuel quality issues. Here is some relevant information: 1. The EPC indicator light is quite common in Volkswagen vehicles. After turning the ignition key, the vehicle begins self-diagnosis, and the EPC light will illuminate for a few seconds before turning off. If it remains on after starting the vehicle, it indicates a fault in the mechanical or electronic systems. 2. Traditionally, drivers controlled the throttle opening via accelerator pedal through a cable system. In the EPC system, the mechanical throttle cable is replaced with pedal position sensors. The engine control unit (ECU) calculates the optimal throttle opening based on data from these sensors and sends signals to the throttle actuator motor to achieve this position. 3. This electronic throttle control is superior to the cable system because it processes input signals from the accelerator pedal to determine engine power requirements and converts this information into engine torque through various actuators.

What Causes the Abnormal Noise When Reversing?

Possible causes include incomplete retraction of the brake pads, looseness in the driveshaft CV joint, or abnormal wear of internal transmission components. It could also be due to particles detaching from the surface of the brake pads, which accumulate on one side of the pad as the brake disc rotates. Below is a detailed explanation of abnormal noises during reversing: 1. The noise during reversing is actually a normal backlash sound. Since the vehicle is moving in the opposite direction, there is a certain gap between the brake pad and the rear end of the bracket. When braking, the brake pad impacts the rear surface of the bracket, producing a clunking noise. This is normal and not a cause for concern. However, if abnormal noises occur, it's important to promptly visit a 4S shop for inspection and repair. 2. Related to torque. Due to the principle of physical torque, the friction pressure at the front and rear ends of the brake pad differs. The front-end pressure is generally significantly lower than the rear-end, which is why in some "multi-piston" caliper products, the pistons closer to the front end of the friction surface are smaller. This torque causes the brake pads to develop a slight difference in thickness between the front and rear ends after wear, meaning a certain degree of uneven wear has occurred. When you suddenly reverse, this balanced uneven wear is abruptly "twisted," leading to abrupt brake engagement during reverse braking and accompanied by squealing noises due to torque imbalance.

How Long Until a Private Car is Mandatorily Scrapped?

For domestic 5-seat sedans and 7-seat SUVs, as well as non-commercial small and micro vehicles, there is no usage period limit. When the normal mileage reaches 600,000 kilometers, the state will guide the vehicle to be scrapped. Apart from the above-mentioned vehicles, small and micro non-commercial passenger vehicles, large non-commercial cars, and wheeled special machinery vehicles also have no usage period limit. Commercial vehicles have scrapping periods, as follows: Small and micro taxi passenger vehicles have a scrapping period of 8 years, medium-sized taxi passenger vehicles have a scrapping period of 10 years, and large taxi passenger vehicles have a scrapping period of 12 years. Public bus passenger vehicles have a scrapping period of 13 years, other small and micro commercial passenger vehicles have a scrapping period of 10 years, and large and medium-sized commercial passenger vehicles have a scrapping period of 15 years. Micro commercial trucks have a scrapping period of 8 years, light and large commercial trucks have a scrapping period of 10 years. The vehicle scrapping process is as follows: The car owner applying for scrapping and renewal must fill out the "Motor Vehicle Change, Transfer, Modification, Suspension, and Scrapping Approval Application Form" in duplicate and stamp the owner's seal. The registration office will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping period. For vehicles that have not reached the scrapping period, after inspection and verification by the motor vehicle inspection office, if they meet the scrapping standards, a "Vehicle Scrapping Notice" will be issued. The owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The owner must submit the "Change Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the motor vehicle inspection office for verification and signature. The license plates and certificates will be reclaimed, and the scrapping registration will be processed according to regulations. Special Notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if the vehicle is damaged and cannot be driven back to the registration location, the owner can sell the scrapped vehicle to a local motor vehicle recycling company. If a commercial vehicle is converted to a non-commercial vehicle, it must be scrapped according to the original commercial vehicle's scrapping period. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation of a motor vehicle's registration, the original owner can apply to use the original license plate number when registering a newly purchased motor vehicle. The application must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation of registration; (2) The owner must have owned the original vehicle for more than three years.
