Does the poor refrigeration effect of Gree air conditioner have anything to do with the small room??

Causes and treatment methods of air conditioner not cooling and poor refrigeration:

1.Insufficient refrigerant. When the refrigerant circulating in the refrigeration system is insufficient, the pressure values on both the high and low pressure sides will be lower than normal, and the bubble flow can be seen from the observation window. At this time, after checking that the air conditioner does not refrigerate the system without leakage, an appropriate amount of refrigerant should be added.

2.Too much refrigerant. If the refrigeration dose charged exceeds the normal capacity of the refrigeration system, the liquid refrigerant in the condenser will inevitably increase, thereby reducing the heat dissipation area and reducing the cooling efficiency.

The main manifestations are: the pressure value of the high and low pressure side of the system is higher than normal, touch the high-pressure pipe with your hand, feel hot and disconnect the air conditioning switch for about 45s, and still see the refrigerant flowing in a foamy state from the observation window. In this case, the appropriate amount of refrigerant needs to be discharged from the low-pressure side to bring it to the normal discharge pressure and temperature.

3.The refrigeration system is dirty. Due to the long-term operation of the compressor, impurities from mechanical wear can cause the reservoir dryer or expansion valve to clog slightly, resulting in insufficient cooling output.

The low pressure value of the system is too low, the pipes before and after the reservoir dryer have obvious temperature difference or frost at the expansion valve, and the reservoir dryer needs to be replaced or the refrigeration system needs to be cleaned.

4.Electronic control circuit failure: the electronic control computer board is also relatively easy to damage, as well as the work parts, compressor internal and external fan damage. When encountering such air conditioning non-refrigeration faults, most of them are repaired with minor faults; Major failure replacement.

All the refrigeration effect of air conditioning is related to the refrigeration area, we often see the air conditioning marked how many horses, is the meaning of refrigeration, this refrigeration capacity to meet the area of the room, generally speaking:

If it is a fixed-frequency air conditioner, the small room with a high-power air conditioner will lead to the frequent opening of the air conditioner, the high-power air conditioner can quickly reach the set temperature, at this time it will be shut down, and then the temperature will naturally rise, the gap between the doors and windows will enter the heat, and the air conditioner will be restarted. In determining the environment. In winter, the wall back to the ground to pull the bricks, the ground to the ground to pull the bricks, 16 square words, 35 hang-up will definitely not work, the general customer said that the area can only be referenced, the key installation master site should pay attention, to explain to the customer, and then determine the installation.

<> use of air conditioners to pay attention to matching. Choose an air conditioner based on the size of the room, which is both comfortable and energy-efficient. In fact, it is okay to choose a large air conditioner to start cooling!

But the cooling is fast, and the heat is also fast! This is a disadvantage of fixed-frequency air conditioners! Temperature-based!

If you set it to 24 degrees, then the compressor will stop after the air conditioner reaches 24 degrees, and only the fan will run idle. I'm a little white electrical appliances, I think it's good to be an expensive cow, a small room is equipped with a beautiful air conditioner, I don't know how many horses, I don't understand, I only know to open dehumidification and refrigeration 30 degrees to sleep on the frozen, awake at noon and make do. Square peg.

Buy a big one, but the reality is that the problem is that it will stop after a while in the summer, and 25 degrees is basically a frequent start-up and shutdown, but it doesn't feel cool, so I have to lower the temperature now, but I feel a little cold, it's really not easy to do. How sensitive are the temperature probes and control systems of the air conditioner that cause the air conditioner to turn on frequently? Frequent start-up and stop of the air conditioner will only occur if the air conditioner is used in a large room.

Generally speaking, the cooling capacity required for every 1 family room is 220W, for example, room 10, choose 22 type air conditioner, or you can use the simplest way, every additional 5, air conditioning to increase the horse, 15 rooms to choose horse. Air conditioning is actually to adjust the temperature and humidity of the room, and the air conditioning ability of Dapi is stronger, provided that the control is accurate. It should not stop, and it should not be able to get up, all of which are control problems.

Of course not. Choosing a large-sized air conditioner for a small apartment will consume more electricity, and the cooling effect is the same, there is no difference at all.

It should be very good, because the area itself is not very large, but taking a large range of air conditioners can have a good cooling effect.

Although this effect will be very good, but it is completely unnecessary, small rooms should choose small size air conditioners, which are not only sufficient, but also lightning.

This effect will be a big improvement, it will also allow us to experience better cooling results, and it will make the home especially comfortable in the summer.

The cooling effect is very, very good, it can quickly lower the temperature in the room, and can be kept at the corresponding temperature for a long time, which is very in line with people's lives.

If the room is smaller, will it be better to choose a larger model of air conditioner for refrigeration?

The cold air sinks heavily, and the hot air gently rushes upward. Therefore, in summer, the air conditioner should be blown upwards and the air conditioner should be blown onto the ceiling, so that the air conditioner will slowly sink from top to bottom. In winter, don't blow the wind upwards, but blow hot air towards the height where the people below are sitting.

Because the hot air can rise upwards, after mastering these two secrets, the small temperature difference in the room will spread unevenly, so it can solve a problem of diligent switching on and off compressors. If the room is not working well, the first thing to do is to confirm whether there is a problem with the air conditioner. According to this logic, what to do with the choice of freezer?

In order to achieve a lower water temperature, the air cooler temperature will be very low.

In fact, the problem is that the indoor wall unit has a temperature regulation system that cannot detect the temperature at a distance diagonally. Only the temperature of the air conditioner wall unit can be detected. When you set it to 26 degrees, the more frequent the start-up and the more balanced the temperature of the whole room, the faster its temperature changes because of the small space.

This is the same as the hot and cold diffusion of pots and small waters. To reduce frequent start-ups, be sure to close the window next to the air conditioner. No leakage with the outside world, no air leakage.

In the summer, shake your head and blow indoors for a few minutes to diffuse the cold air throughout the room, and the number of turns on will also be reduced. It is unreasonable to mention the composition of a large air conditioner in a small room. In order to save electricity, it is generally not advisable to close the door of a small room and turn on the air conditioner.

But the indoor temperature is out of place. It is also possible to open the door and spread outward. In this way, the variable speed air conditioner can continue to run at high frequency for a period of time, saving electricity.

The inverter air conditioner outputs high-frequency voltage, and the high-frequency motor uses a small current), so the decoration should consider the composition of the room and the number of air conditioners.

The heat in the room is constant, which is actually cold. So, choose an air conditioner. If the heat or load of the room is 3500w, I want a 3500w air conditioner, generally.

Choose 1p and choose the small one, the problem is that the room can't be cooled down or it takes a long time. If you choose a large one, choose 5p, this one will choose a large one, if you choose a large one, the room will cool down quickly, reach the set temperature, and then stop immediately, or change the operation of the device. The effect does not go bad, but for the better.

But this can also become a problem. That is, the air conditioning adjustment range is narrower. The family's choice is usually not too outrageous, and you can't fit an oversized air conditioner in a small room.

If the room is small, there is no need to choose a large rear air conditioner. Generally, the room is small and chooses a medium-sized air conditioner, and its cooling effect is also very good.

If your room is smaller, choose a large model of air conditioner, of course, the cooling effect will be better, it will be more comfortable, and it will feel more in summer.

It wouldn't be better, because a small room with a large air conditioner is wasteful, and it's easy to shut down.

No, and using such an air conditioner will also make your home more power-intensive, and it will also make your home look smaller, and it will also take up a very large area.

The effect will be better, but it is not necessary at all, because it will consume more electricity.

Dear, hello, I'm glad to answer for you, why is the cooling effect worse if the air-conditioned room of the same size is smallA: The air-conditioning is big, the room is small, will the refrigeration effect be bad? The question you raised is about the principle of thermal diffusion, just like half a basin of hot water and half a cup of hot water should be cooled down to 26 degrees, a large basin of water will last after cooling, and a small cup will be close to the room temperature.

Do you know? In summer, the air conditioner should face upwards and let the cold air blow above the ceiling, so that the cold air will slowly sink from above. In winter, don't turn the tuyere door up, but blow hot air at the height of the people sitting below, because the hot air will float upward, so if you master these two tips, you can solve one aspect of the problem of turning the compressor on and off frequently because of the uneven diffusion of temperature difference caused by the small room.

You put forward the difference between the size of the room and the size of the air conditioner, in fact, the problem is that there is a temperature control system in the indoor wall unit, it can not measure the temperature diagonally far away, it can only sense the temperature in the air conditioner wall unit, when you set it to 26 degrees, whether it is heating or cooling, the temperature transmitted into the wall machine outdoors is sensed by the temperature control head and it conducts the shutdown (I have a lot of experience when designing the temperature control device), this time is not the same 26 degrees as the indoor space, the smaller your indoor space, the more frequent the start of the start, When the temperature of the whole room is balanced, its temperature change will also be faster due to the small space, which is the same as the cold and hot diffusion of large basins and small cups of water. In order to reduce the frequent start-up of the machine, you need to close the window next to the air conditioner tightly, so that there is no gap with the outside world, if there is a moving head fan in the room in the summer to blow for a few minutes, so that the air conditioning spreads throughout the room, it will also reduce the number of start-ups. You mentioned that the configuration of the large air conditioner in the small room is unreasonable, in order to save electricity, it is generally advocated that the small room is closed and the air conditioner is opened, and the outer room is not opened, but the indoor temperature is very uncomfortable, and the door can also be opened to spread to the outer room, so that the inverter air conditioner can persist in high-frequency operation for a period of time to save electricity.

The inverter air conditioner outputs a high-frequency voltage, and the small current is supplied to the high-frequency motor), so the decoration should consider the configuration of the room and the number of air conditioners.

Not only is it not bad, but on the contrary, this cooling effect is indeed the best. It can reduce the temperature of the room very quickly, and the ability to heat is also very strong.

It will definitely be better, because the room is smaller, the cooling effect will be more obvious, and the power of the air conditioner will also decrease.

I don't think so, because it's easier to cool down if the room is small.

Theoretically, the air conditioner has a large room and a fast cooling or heating rate, but the compressor of the air conditioner may start relatively frequently, but it will consume more electricity! As for the statement that the refrigeration effect is not good, it feels a bit two!

This is also the case in my family, and the air-conditioning master said that the large air conditioner and the small room are the reasons for the lack of refrigeration, but this is the first time I have heard of it.

Air conditioners have sizes, rooms also have sizes, if they match will be more comfortable, the sense of experience is stronger, big is not good, small is not good. It's as simple as that.

The air conditioner is big, the room is small, the refrigeration speed of the air conditioner is very fast, and when the indoor temperature is adjusted, the duration is relatively long, and the outdoor unit will not always rotate.

I don't think that the cooling effect will be very good with a large air conditioner, we can consider some air conditioners with less power and can cool well, so as to have a strong cooling effect

If the mode setting is incorrect, and the temperature and wind speed settings are unreasonable, select the mode again and set the appropriate temperature and wind speed.

The filter screen is dirty, the air inlet and outlet of the indoor unit are blocked, and the angle of the air deflector is too small: clean the filter screen, remove the obstruction of the air outlet, and adjust the angle of the air deflector.

Doors and windows, exhaust fans, etc. are not closed, resulting in poor room insulation: close doors, windows, exhaust fans, etc.

The room area is large, and the air conditioning type is small: it is recommended to increase the wind speed.

When heating, the electric auxiliary heating function of the air conditioner is not turned on: Turn on the electric auxiliary heating function of the air conditioner.

The various reasons for the poor cooling effect of air conditioners are as follows:

1. The refrigerant of the system is insufficient.

2. The system is slightly blocked.

3. The internal fan network is blocked.

4. The heat dissipation effect of the external unit is poor.

6. The temperature control circuit is faulty.

7. The speed of the internal fan is too slow.

8. The room is too large or has poor thermal insulation performance.

9. Too much refrigerant liquid.

10. The exhaust is not enough when the air conditioner is installed.

11. Four-way valve string.

12. The power supply voltage is unstable.

If it is a problem with the air conditioner, it should be repaired in time.

Domestic brands will be worse, and the best is still Japanese.
