The air conditioner will not be cooled at noon when the sun is shining, what should I do?

The outdoor unit is not refrigerated after being directly exposed to the sun, which is mainly due to the following reasons:

First, the installation position is not suitable, resulting in poor ventilation and heat dissipation of the outdoor unit. A sun visor can be added if convenient.

The second is that the speed of the external fan motor is too slow, such as the capacitor capacity decreases, and the new capacitor of the same capacity should be replaced. If the motor bearing is seriously worn or the lubricating oil is dry, such as the motor is noisy, it should be replaced with a new bearing or lubricating oil.

The third is that the external unit is too dirty, which hinders ventilation. The temperature exchanger (finned foil heat sink) should be cleaned thoroughly, either directly with a tap water hose or with a soft brush dipped in water and brushed up and down. Or find an empty bottle, drill a hole in the cap, fill it with water and spray it up and down.

The inner unit should also be kept clean and clean, and the filter screen should be cleaned regularly.

If it is not possible after the appeal is processed, it is recommended to contact the after-sales service or ask a professional for maintenance.

First of all, consider whether the outdoor unit of the air conditioner is directly exposed to the sun, if it is directly exposed to the sun during the time period when it is not cooling, it may be the exhaust temperature or exhaust pressure protection; (Outdoor units need to be properly shielded).

Secondly, find a professional maintenance personnel to check whether the amount of refrigerant in the refrigeration system is appropriate.

If the air conditioner is not refrigerated, it may be that the refrigerant in the air conditioning system is leaked, resulting in no refrigerant, you can check whether the parts in the air conditioning system are damaged and cause the leakage of refrigerant, if the leakage needs to be supplemented; It may be that the internal damage of the air conditioner pump makes it impossible to start refrigeration, it is recommended to check the air conditioner pump, if it is damaged, it needs to be replaced; It may be that the condenser heat sink is too dirty, in order to protect the air conditioning system, the air conditioner pump stops working, you can use a high-pressure water gun to clean the condenser heat sink.

There is a way to solve it, hand over a few basins of water to the outside machine, lower the temperature of the outside machine, and refrigerate it when it is turned on, and the new machine is unlikely to have this situation.

Noon is the highest temperature of the day, the outside unit of the air conditioner is limited due to the high temperature, your air conditioner should be a few years ago products, the current ** air conditioner overcomes this, no matter whether the outside temperature is too high or too low will not affect the cooling and heating effect of the air conditioner. You can give a certain cooling measure and install a sun protection device on it.

In this case, you should find a professional master who repairs the air conditioner to repair it, and don't do it yourself, safety is important.

Dust filter, take it out, clean it up.

If you don't refrigerate, you have to find after-sales maintenance.

It is most likely caused by insufficient refrigerant.

Because the external machine is full of heat pipes and heat sinks. If the sun disperses, it will increase the heat dissipation burden of the external unit. This reduces the cooling effect. Refrigeration consumes electricity, the outdoor temperature is high, and the compressor has to work more during refrigeration.

When the air conditioner is not cooling, you should first check whether the various parts of the air conditioner are blocked. Because of the blockage of filters, condensers, gas pipes, etc., the cooling effect of the air conditioner will be reduced. When using the air conditioner, you will always feel that the air conditioner is not cooling.

1. The reason why the air conditioner is not refrigerated is that the air conditioner is not refrigerated --- blocked.

2. If the condenser of the outdoor unit or the filter of the internal unit is blocked and the situation of no refrigeration is caused, the solution is very simple. Just clean up the clogged stuff by hand. In fact, the air conditioner should be cleaned every once in a while to achieve a good use effect.

3. The condenser is also known as:"Liquefiers"It is one of the main equipment in the refrigeration unit, in the refrigeration process, it is the heat exchanger for the refrigerant to release heat to the outside of the system, and the superheated steam of the refrigerant from the compressor enters the condenser, and the heat is transferred to the surrounding medium water (or air), and it itself condenses into a liquid state (i.e., liquefaction) due to the release of heat (mainly latent heat).

4. When the chiller passes through the condenser, there is a high-pressure vapor state that changes to a high-pressure liquid state at about 1 3 places in length. During this transition, there is a slight change in temperature, depending on the ambient temperature.

Reasons why the air conditioner is not cooling:

1.First, see whether the refrigerant of the air conditioning mechanism is sufficient, if there is no sufficient refrigerant, it should be added, first use a button ammeter to measure the amount of current required by the air conditioner itself, so that it is filled with refrigerant not to be excessive, if the effect is not good, it depends on whether the setting value on the control board is correct.

2.If the connecting copper pipe and capillary pipe of the unit are not blocked, then we should analyze whether the electromagnetic refrigerant control valve is blocked or stuck, or not fully working, we first use the atomic table to test the high pressure, what kind of phenomenon does the low pressure have. If the high pressure is very high and the low pressure is very low, or negative pressure, then it means that the solenoid refrigerant control valve is not fully opened or is completely stuck, first understand the role of the solenoid refrigerant control valve.

3.During refrigeration, the electromagnetic refrigerant control valve is opened to a minimum of 20 steps, a maximum of 480 steps, a minimum of 20 steps for heating, and a maximum of 480 steps.

4.Let's check whether the coil resistance of the solenoid refrigerant control valve is consistent with its technical parameters. If it is unanimously stated that the coil is good, the next thing should be to see whether the computer board gives the output voltage value to the wire, if the output voltage value and technical parameters are the same, it means that the computer board is giving instructions, and the electromagnetic refrigerant control valve has not yet operated, then the mechanical part of the electromagnetic refrigerant control valve is stuck or blocked by dirt, then the electromagnetic refrigerant control valve must be replaced in order to achieve the refrigeration effect.

The outdoor unit does not dissipate heat, resulting in the failure of the air conditioner, and the light lights up, the first to add an awning to the outdoor unit, and a certain distance from the air conditioner, if the conditions permit, the whole set of air conditioning is replaced to the wall that cannot be exposed to the sun in the afternoon, I installed it like this.

Second, when the refrigeration effect is not good, try to sprinkle water on the heat dissipation blades of the outdoor unit of the air conditioner, and sprinkle more points, but this does not cure the symptoms

In addition, the success rate of fan modification of outdoor units is slightly larger, which can be improved, and it is still a symptom rather than a cure.

So it's still an awning, it's best to block the sun all and the air won't be airtight, it's best to type out all the text with one hand, shouldn't you give me extra points?

Does basking in the sun make a difference? Look at the settings of your air conditioner, see if there is a timer or something, I haven't heard that the sun will shut down. It may be that the circuit board is faulty and stops running for a while, so it is recommended to ask a professional to check it.
