The cooling effect of the car air conditioner in summer is slow, what is going on?

Hello, the car air conditioner is not well refrigerated in summer, first check the air conditioner filter. When the air conditioner is turned on, the air blown out by the blower is sent to the cab through the air conditioning filter, if the air conditioning filter is dirty, the wind will be blocked, the air volume is small, and the refrigeration effect will be worse. You can remove the filter element for inspection, and if it is too dirty, replace it.

Open the inner loop. When turning on the air conditioner, adjust the internal and external circulation buttons on the air conditioning control mechanism to internal circulation, so that there will be no outside hot air to exchange with the inside of the car, and the cooling effect will be better. Also, do not smoke in the car when the internal circulation is open.

Adjust the wind direction. Because the air conditioner is heavier than the hot air, it should be upward when choosing the wind direction, and when the cold wind blows on the face, people feel cooler, so when turning on the air conditioner, the wind direction should be adjusted to the position of blowing the face.

It may be due to a failure of the air conditioning and refrigeration system, or it may be caused by a lot of dust accumulation, or it may be that the corresponding parts have not been replaced.

It may be that the air conditioner filter is dirty and the air outlet is blocked, and the cooling effect of the air conditioner is not good, so the air conditioner filter should be replaced or cleaned up.

It may be caused by a problem with the filter element, if the filter element is particularly dirty, the air will be blocked, and the cooling effect will be very slow.

It may be that the air conditioning and refrigeration system is faulty, or it may be that there is a lot of dust accumulation, or it may be that the corresponding parts are not replaced.

The heat dissipation is not good, the refrigerant is not enough, and there is a problem with the pressure sensor.

Lack of fluorine, the air conditioning filter is dirty, and the internal circulation is not opened!

You can write an article about the reasons why the refrigeration effect is not good. If your air conditioner has been used for several years, it is recommended to add some fluoride. Direct fluoride. Otherwise, you see that the maintenance personnel will have to slaughter you, if the effect is still not good after adding fluoride, it is recommended to have to pay for maintenance.

Summary. Hello, master, in this case, the first thing you need to check is whether the air conditioner refrigerant is normal. Check the pressure of the air conditioner, the low pressure is around 30 40, the high pressure is 120 150, and use the high-pressure water gun to flush the condenser of the air conditioner.

If it is too dirty, it will cause the air conditioning system to dissipate heat poorly, and use the diagnostic computer to read whether the request signal of the air conditioner pressure sensor is on when the AC is turned on. Check whether the air conditioner tank fan is working properly? In this case, if you repair and deal with it, it will be about 3 400 yuan, and there may be differences in each place**.

What is the reason why the car air conditioner runs at high speed and does not refrigerate at low speed?

Hello, master, in this case, the first thing you need to check is whether the air conditioner refrigerant is normal. Check the pressure of the air conditioner, the low pressure is around 30 40, the high pressure is 120 150, and use the high-pressure water gun to flush the condensation gear of the air conditioner. If the bureau is too dirty, it will cause the air conditioning system to dissipate heat poorly, and use the diagnostic computer to read whether the request signal of the air conditioning pressure sensor is turned on when the AC is turned on.

It can't be that the air conditioner compressor is broken.

Freon just added.

In this case, it may be that there is a problem with the compressor, first check whether there is any air leakage in other places.

How much does it cost to replace the air conditioning compressor of the old Besturn B50.

If it is determined that it is a problem with the compressor, the replacement cost is about 800 yuan, and there may be differences in each place.

Is there a high chance that the compressor will break? I'm worried about being fooled by the repair shop.

If there is no air leakage in other pipes, the point is that there is a problem with the compressor.

Can I test if there is an air leak in the area and how to check it? Excuse me?

Use the air conditioner pressure gauge to put pressure in. Wait an hour or two to check if the pressure gauge has dropped.

1.The vehicle has just started, the engine temperature has not yet risen, and it is OK after the car is warmed up2Lack of coolant, insufficient coolant will also cause the car air conditioner not to heat, add coolant can be 3

The water pump is damaged, resulting in the failure of the coolant circulation system, and it will also cause the car air conditioner to not heat, so the water pump can be replaced.

4.The warm air water tank is blocked, and the hot water inside the engine cannot be circulated in the water tank, causing the air conditioner to not heat up, and the warm air is cleaned.

5.If the radiator fan fails, the radiator fan will continue to dissipate heat, which will make it difficult for the coolant inside the water tank to heat up, and the air conditioner will not heat.

The reason may be that the refrigeration system causes the heating mode to start slowly, and before the heating mode of the air conditioner officially starts, it needs a period of preheating, that is, waiting for the air sent by the outdoor unit to reach a certain temperature, and the air supply outlet of the indoor unit will start to operate. The warm-up time of different air conditioners is different, generally between 5 minutes and 10 minutes. Hope it helps, dear.

Car heater is the cooling system of the engine in the process of dissipating heat from the engine, and the heat is introduced into the car by a small fan; When the heating is turned off, the fan stops and the hot air vent is turned off, and the heat is dissipated into the atmosphere.

The vehicle heating system is not hot can be divided into two reasons, one is caused by the engine cooling system, and the other is caused by the poor work of the heating control mechanism.

Tips for turning on the heater in winter: The heater needs the heat of the engine or the exhaust gas to be filtered for heating. If the engine temperature is too low at the beginning, turning on the heater will increase fuel consumption on the one hand, not to mention the slow arrival of the heater.

If you don't have a water temperature meter installed, it is recommended that the water temperature will go up in 5-10 minutes after you start. You can turn on the heater (if you have installed OB

Set the air conditioner to the heating state, select high air indoors, and measure the temperature of the air outlet of the indoor unit after 2 minutes of air outlet, if the temperature reaches more than 38 degrees, then there is basically no problem with the air conditioner.

The general reasons for insufficient air temperature are:

1. Lack of fluorine: 2. The outdoor environment temperature is too low or the humidity is too high.

3. The installation position of the outdoor unit is the tuyere, which is always blown by the cold wind.

4. No auxiliary electric heating or auxiliary electric heating is bad.

Law steps.

The outside temperature will affect the heating effect of the air conditioner. If you are in a cold winter, and the outside temperature is too low, the heating effect of the air conditioner will also be affected, and the indoor heat is not enough, which will affect the heating effect of the air conditioner.

The filter will also affect the heating effect of the air conditioner. In fact, many people will be more aware of the cooling effect than heating, if there is a problem with your filter, the cooling will be affected, and the same is true for heating, so check your filter regularly.

The third point is that the area of the room is too large, and the heating will be slower. If your room is very large, then the heating effect of the air conditioner will definitely not make your room warm up immediately, but will only slowly increase the temperature.

The fourth point may be that the heating power of the air conditioner is too low, resulting in slow heating. If you don't want to match the heating power of the room and the air conditioner, it will be difficult for your room to heat up, so pay attention to the size of your room when buying an air conditioner, which will better meet your needs.

The fifth point is that the air conditioner is slow to heat up due to your voltage being too low. If your air conditioner is a high-power air conditioner, and your voltage is not so big that it cannot meet the voltage of the air conditioner, the heating effect of your air conditioner will be relatively poor.

And one last point, it may be that your room is not tightly closed. Many people will easily forget this reason, always think that their room is tightly closed, but in fact, it is not, so remember to close their room when turning on the air conditioner, so that the heating will be faster.

The following are the reasons for the slow refrigeration of automobile air conditioners: 1. Too little refrigerant causes insufficient refrigeration. 2. There is water infiltration in the air-conditioning and refrigeration system, resulting in insufficient refrigeration.

3. The condenser is too dirty, resulting in a decrease in heat dissipation capacity, which leads to a decrease in the refrigeration capacity of the air conditioner. 4. The slippage of the air conditioning belt leads to the lack of compressor power digging, resulting in slow refrigeration of the air conditioner. The following are the maintenance methods for car air conditioning and refrigeration:

1. Do not adjust the direction of the air outlet of the air conditioner at will, according to the principle of cold air sinking and hot air rising, the correct approach should be to turn on the air outlet upwards when the air conditioner is turned on, and the air outlet is downward when the heating is turned on. 2. The air conditioner should be started regularly, and the air conditioner should be started regularly to allow all parts to accept the lubrication of the lubricating oil and maintain a good state, so it is best to start the air conditioner once a week in winter. 3. The use of air conditioning for a long time should not be too long, as the use of air conditioning for a long time will cause excessive pressure in the condenser and cause loss to the refrigeration system.

The solution to the slow refrigeration of automobile air conditioner is as follows: 1. The radiator needs to be cleaned. When the heat exchanger is covered with a large amount of dust, cobwebs and other garbage, it cannot effectively dissipate heat, resulting in poor refrigeration effect of air conditioning, and the heat exchanger of the internal and external units needs to be cleaned; 2. The outdoor temperature is too high.

If the outdoor temperature is too high, you should pay attention to the surrounding environment when using the outdoor unit, which can make the surrounding air circulate more in an environment far from high temperature, and also help the refrigeration of the air conditioner. If the air conditioner is placed in an environment with too high temperature, the heat will not be dissipated, resulting in no refrigeration; 3. There is no cleaning and maintenance. There is no cleaning and maintenance because the outdoor unit is installed outdoors, it is easy to be ignored, and if it is used for a long time, there will be some dust, garbage and other dirt on it, which will affect the heat dissipation effect, so that the air conditioner is not refrigerated.

If the air conditioner is regularly maintained, it will be of great help to the cooling effect of the air conditioner. Therefore, when using the air conditioner, it is necessary to carry out various maintenance of the air conditioner.
