What s going on with the Chery E5 air conditioner internal circulation not working

The internal circulation of the car air conditioner does not work, first look at whether the exhaust pipe is disconnected, and the solenoid valve pipe of the carbon canister is loose, which is generally the problem of the exhaust pipe.

The automotive air conditioning and refrigeration system consists of a compressor, a condenser, a liquid storage dryer, an expansion valve, an evaporator and a blower. Copper pipes (or aluminum pipes) and high-pressure rubber pipes are connected into a closed system between the components. When the refrigeration system works, the refrigerant circulates in different states in this closed system, and each cycle has four basic processes:

1. Compression process: The compressor sucks in the low-temperature and low-pressure refrigerant gas at the outlet of the evaporator, compresses it into high-temperature and high-pressure gas and discharges it out of the compressor.

2. Heat dissipation process: the superheated refrigerant gas at high temperature and high pressure enters the condenser, and due to the decrease of pressure and temperature, the refrigerant gas condenses into liquid and discharges a large amount of heat.

3. Throttling process: The volume of the refrigerant liquid with higher temperature and pressure becomes larger after passing through the expansion device, and the pressure and temperature drop sharply, and the expansion device is discharged in the form of mist (fine droplets).

4. Endothermic process: the mist refrigerant liquid enters the evaporator, so the boiling point of the refrigerant is much lower than the temperature in the evaporator, so the refrigerant liquid evaporates into gas. During the evaporation process, a large amount of surrounding heat is absorbed, and then the refrigerant vapor at low temperature and low pressure enters the compressor.

This process is repeated to reduce the temperature of the air around the evaporator.

The functions of automatic air conditioning include automatic adjustment of temperature and humidity in the vehicle, automatic control of return and supply air modes, and control of operation mode and air exchange volume. The electronic control unit will make the air conditioning system run automatically according to the settings made by the driver or passengers through the buttons on the air conditioning display control panel, and adjust the air supply temperature and air supply speed in time according to the signals input from various sensors, so that the air environment in the car can be kept in the best condition.

The maintenance of fixed-frequency air conditioners is mainly divided into three functional modules: 1. Inspection and maintenance of electronic control system; 2. Inspection and maintenance of refrigeration system; 3. Detection and maintenance of installation faults;

Inspection and maintenance of electronic control system: it is divided into monitoring and maintenance of indoor side electric control board and electrical parts; Monitoring and maintenance of outdoor electrical components.

Monitoring and maintenance of refrigeration system: it is divided into monitoring and maintenance of shut-off valves, heat exchangers, connecting pipelines, four-way valves, compressors, capillaries, refrigerants, etc.;

Monitoring and maintenance of installation faults: divided into abnormal faults caused by assembly, installation and maintenance factors such as noise, water leakage, and wind deflector jitter;

Necessary maintenance tools;

Basic knowledge of air conditioning;

basic operational skills;

Cleaning the air conditioner is actually very simple, go to the supermarket and buy a bottle of air conditioner disinfectant, and you can do it yourself! First remove the filter, rinse it with water, then spray the disinfectant evenly on the heat sink for disinfection, and finally install the filter and turn on the refrigeration mode......I use Jia'an at home, the effect is very good, and the sprinkler head is also very good. You can also clean the air conditioner yourself

The maintenance of the air conditioner includes the maintenance during the service life and the maintenance during the shutdown period. The main maintenance during the use period is as follows: 1. Clean the filter regularly, generally once every two weeks, and more frequently in dusty areas.

If the air conditioner is equipped with deodorization and dust removal filters, it should be cleaned and replaced regularly according to the instructions in the manual; 2. If the voltage in the area is unstable for a long time (manifested as difficulty in starting the fluorescent lamp, slower fan speed, etc.), it will affect the normal use and life of the air conditioner, and the user should better configure the voltage regulator by himself; 3. There should be no heat source near the internal unit of the air conditioner, otherwise it will affect the performance of the air conditioner, and the plastic parts of the internal unit will be deformed, which will not only affect the appearance but also increase the noise; 4. For dust removal on the surface of the air conditioner, the power supply should be cut off first, and then wiped with a dry cloth, and it should not be washed with water. The maintenance during the shutdown period mainly includes the following points: 1. Before long-term shutdown, the ventilation shield should be opened to dry the moisture in the indoor unit; 2 Unplug the power supply and remove the battery in the remote control; 3. If possible, cover the inner and outer units with a cover to keep the indoor and outdoor heat exchangers clean.

Before the season of use, the air conditioner should be inspected. First of all, remove the covers on the internal and external units, remove the obstacles on the indoor and outdoor air inlets and outlets, then install the remote control battery, turn on the power of the air conditioner, and observe whether the air conditioner is running normally after turning on the machine.

It should be broken, go find someone to fix it, don't mess around if you don't understand.

That's broken, look for after-sales.

If the Chery E5 car has frequent on-time interruptions when using the air conditioner, it may be caused by the following reasons:

1.The refrigerant pressure is too low: when the refrigerant pressure in the air conditioning refrigeration system is too low, the electromagnetic clutch will automatically disconnect the power supply and stop working.

2.Air conditioning compressor failure: The air conditioning compressor is the core component of the air conditioning and refrigeration system, if there is a failure or damage, it will cause the air conditioner to be unable to refrigerate normally, and the air conditioner compressor needs to be replaced.

3.Electromagnetic clutch failure: The electromagnetic clutch is a key component in the air conditioning compressor, if there is a failure, it will cause the refrigeration system to not work normally, you can measure the resistance value on the electromagnetic clutch to judge.

4.Failure of the air conditioning control system: The failure of the air conditioning control system will cause the air conditioner to work normally without opening the method, including sensors, computer boards and other components.

If the above methods cannot solve the problem, it is recommended to go to a car repair shop or 4S shop for repair. It should be noted that air conditioning system repairs usually require professional equipment and technology, and it is not recommended for individuals to carry out self-repairs.

Summary. Hello, the steps related to turning on the heater of the vehicle are as follows, first, the prerequisite for the heater to turn on is that the water temperature must rise before the heater, because the heater of the vehicle is heated by the temperature of the engine and the coolant. Second, the vehicle generally, idle in situ for about ten minutes, or drive for about ten minutes, the water temperature will slowly rise third, after the water temperature rises, directly turn on the wind speed in the air conditioning panel area, adjust the temperature up, adjust the position of the air outlet to the position of blowing the face or blowing the feet, under normal circumstances, the warm air will come out Third, in winter, it is not recommended to open the separate button of the front windshield defogging, because after this button is lit, the AC light will also be on, and the cold air conditioning of the vehicle will also start.

In winter, this forced start is no good for the compressor!

Chery E5 how to turn on the rear seat heater.

The front row of the vehicle is adjusted to the position of blowing the face, and the rear row is heated by the heater.

The old blockage of the automobile air conditioning system is a problem that the refrigerant pipeline system has not dealt with, 1. The vacuum must be accurate, otherwise the moisture contained in the air in the pipeline will freeze at the expansion valve, leading to the blockage of the system.

2. Or other foreign substances are mixed into the refrigerant pipeline system, forming a blockage in the expansion valve or compressor.

There are other possible causes of the spine, and it is recommended to find a professional to carefully evaluate and check it.

Hope it can help you, satisfied. If you have any other questions, please feel free to ask them. Thank you.

We recommend that you perform the following steps for troubleshooting and troubleshooting:

1. Determine whether the anti-theft system is locked;

2. Determine whether the starting system is working (whether the starter is running);

The starting system is normal, check whether the ignition system is normal;

The starting system is abnormal, rotates slowly, check the battery voltage, whether the starter is faulty, and whether the engine resistance is too large; If the starter is not running, check the circuit and solenoid switch of the starter.

The ignition system is normal, check whether the fuel supply system is normal.

If the ignition system is abnormal, check the circuit of the ignition system, check whether the crankshaft position sensor and camshaft position sensor are normal, and check the power supply and grounding of the ECU.

The car runs long distances, and the engine drives the compressor to refrigerate at high speed, and the refrigeration effect is particularly good.

The refrigeration efficiency is high, the lower the temperature in the car, and finally the circulating airflow in the car has no heat to exchange heat with the refrigerant, resulting in the refrigerant can not be completely vaporized into gas back to the compressor, so the liquid refrigerant returns to the compressor to form liquid compression, the return gas pipe begins to freeze, and finally the evaporator also begins to freeze, the antifreeze switch jumps, the compressor does not refrigerate, the fan is blocked by ice and cannot circulate the airflow, the wind is getting smaller and smaller, and it is not cold.

In addition to the low temperature in the car, there is also the possibility that there is too much refrigerant, or the heat exchange efficiency is low due to the dust accumulation and dirt of the evaporator fins, and the heat cannot be absorbed.

It may also be due to high pressure, poor heat dissipation, etc., resulting in a decrease in refrigeration effect; Even overheating load protection trips out of stops.

There are other possible causes, and it is advisable to find a professional to evaluate them carefully.
