The outside temperature is cooler than the temperature of an air conditioned room3

In refrigeration mode, when the temperature set by the air conditioner is high, the fan of the indoor unit of the air conditioner works to circulate indoor air; Because the temperature detected by the air conditioner is lower than 26 degrees, it is considered that there is no need for refrigeration, so the outdoor unit stops working, but the fan does not stop running, and the power consumption is not large, but it will affect the life of the working electrical appliances.

In the automatic mode, the temperature detected by the air conditioner is lower than the set temperature of 26 degrees, in order to maintain the indoor temperature, the air conditioner will automatically switch to the heating mode and start working, at this time, the air conditioner is in a full load state, and the power consumption is naturally large for the rated power of heating.

If the use environment needs to be maintained at 26 degrees, the working mode should be set on the automatic, if there is no temperature requirement, it is recommended to shut down: 1. Extend the service life of the equipment 2. Save power although there is very little, reduce noise 3. Respond to the national call to contribute to national energy conservation and emission reduction.

1. In this case, you don't need to turn on the air conditioner, just open the window.

2. Be sure to turn on the air conditioner (it has the effect of changing the indoor air flow), then only when the fan is in use, it does not consume much electricity, and there is no damage to the air conditioner, but the premise is that it is turned on in the refrigeration state, not in the automatic state, otherwise it will be heated.

The same is turned on to 26 degrees, and the lower the outdoor temperature, the more power saving. This does not cause too much damage to the compressor. Whether the air conditioner runs depends on the indoor temperature, you turn on 26 degrees, if the indoor temperature is lower than 26 degrees, the air conditioner is not allowed to heat up, and if it is above 26 degrees, it is cooling.

The outdoor temperature of the refrigeration is lower than the indoor temperature, and the air conditioner can also cool the air. The cooling function of an air conditioner has little to do with the outside temperature. As long as the room temperature is higher than the set temperature of the air conditioner, the compressor of the air conditioner will run.

It's just that the outdoor temperature is lower than the indoor temperature, so the inverter compressor will reduce the frequency and the power consumption will be lower. As the air conditioner works, the indoor temperature gradually decreases. When it is lower than the set temperature, the air conditioner compressor will turn off.

The answer applies to air conditioners of brands such as Midea, Gree, and Haier. When the outdoor ambient temperature is above 0, most air conditioners can operate normally. And when the outdoor ambient temperature is below 0 and below minus 7, many air conditioners cannot work normally, and only special air conditioners can continue to work, such as air conditioners specially designed for steel mill steelmaking workshops.

The principle of air conditioning refrigeration refers to the principle of air conditioning and refrigeration operation. After the air conditioner is energized, the low-pressure steam of the refrigerant in the refrigeration system is sucked in by the compressor, compressed into high-pressure steam, and then discharged into the condenser, and the indoor air is continuously circulated and flowed, so as to achieve the purpose of cooling. Therefore, the operation of the air conditioner mainly depends on the relative difference between the set temperature of the room and the actual indoor temperature, and has nothing to do with the indoor and outdoor temperature.

It's just that when the outdoor ambient temperature is lower than the indoor temperature, the power consumption of the air conditioner is relatively low.

1. In this case, the general air conditioner will still refrigerate. 2. The work of air conditioning mainly depends on the relative difference between the indoor set temperature and the actual indoor temperature, and has nothing to do with the indoor temperature. 3. It is just that when the outdoor ambient temperature is lower than the indoor temperature, the power consumption of the air conditioner for refrigeration is relatively low.

Relevant knowledge expansion: 1. After the air conditioner is energized, the low-pressure steam of the refrigerant in the refrigeration system is sucked in by the compressor and compressed into high-pressure steam and discharged to the condenser, and the indoor air is continuously circulated to achieve the purpose of reducing the temperature. 2. The outdoor air inhaled by the axial fan flows through the condenser, taking away the heat released by the refrigerant, so that the high-pressure refrigerant vapor condenses into a high-pressure liquid, and the high-pressure liquid is sprayed into the evaporator after passing through the filter and throttling mechanism, and evaporates under the corresponding low pressure to absorb the surrounding heat.

3. At the same time, the cross-flow fan makes the air continuously enter the ribs of the evaporator for heat exchange, and sends the cooled air to the room after heat release, which is the principle of air conditioning and refrigeration, so when the outdoor temperature is lower than the indoor temperature, the air conditioning and refrigeration will not be affected, and the outdoor temperature will not be low without refrigeration.

Take beauty as an example:

The outside temperature is lower than the indoor temperature, and it is still possible for the air conditioner to cool down. The cooling function of the air conditioner has little to do with the outdoor temperature, as long as the indoor temperature is higher than the temperature set by the air conditioner, the compressor of the air conditioner will run. It's just that the outdoor temperature is lower than the indoor temperature, and the inverter compressor reduces the frequency, and the power consumption will be lower.

As the air conditioner works, the indoor temperature gradually decreases, and the air conditioner compressor will only turn off when it is lower than the set temperature.

This answer applies to air conditioners of Midea, Gree, Haier and other brands.

If the outdoor ambient temperature is above 0 degrees, most air conditioners can be refrigerated and operated normally. However, when the outdoor ambient temperature is below 0 degrees and below minus 7 degrees, many air conditioners cannot operate normally, and only special-purpose air conditioners can continue to work, such as air conditioners specially designed for steelmaking workshops in steel mills.

It's just that when the outdoor ambient temperature is lower than the indoor temperature, the power consumption of the air conditioner is relatively low.

Summary. It should be caused by the abnormality of the control circuit, and you should contact the after-sales service or ask professionals for maintenance. The emergency treatment is to check whether the temperature probe of the indoor unit is displaced or too dirty, otherwise it can be adjusted to the dehumidification mode for refrigeration and cooling.

The outside temperature is lower than the indoor temperature, and the air conditioner doesn't feel cool.

The principle of air conditioning refrigeration: the liquid refrigerant is used to absorb heat during vaporization, and the absorbed heat is transferred from low temperature to high temperature, that is, the direction of transfer is from low temperature to high temperature. In nature, the direction of heat transfer automatically occurs from a place with a high temperature to a place with a low temperature, and there is no need to consume other forms of energy.

For example, the natural flow of water is the conversion of gravitational potential energy into kinetic energy from high to low under the action of the earth's gravity (gravity), without the need to consume other forms of energy. Conversely, water flows from a low place to a high place, which cannot occur automatically, and must consume chemical or electrical energy. The directionality of energy transfer or conversion determines that heat transfer can only occur automatically from a place with a high temperature to a place with a low temperature.

If the outdoor temperature is low and the indoor temperature is high, the heat transfer can automatically occur and the indoor temperature drops, and there is no need to consume electricity, so the air conditioner will stop cooling. Only when the indoor temperature is higher than the outdoor temperature, and the heat transfer is reversed, the air conditioner starts to operate, and it consumes electrical energy to absorb the indoor heat and is in a cooling state. <>

There will be no problem with the outside temperature being lower than the air conditioner. Whether the air conditioner is refrigerated or not has nothing to do with "the outdoor temperature is lower than the set temperature of the air conditioner", but has something to do with the indoor temperature.

Air conditioner not cooling reasons:

1. The refrigeration capacity of the air conditioner is certain. When the air conditioner is on and cooling and the ambient temperature is more than 5 degrees different, the air conditioner will only be able to reduce the temperature after the constant temperature reaches a certain value, because the capacity of the air conditioner is certain.

2. The power of the air conditioning compressor is "horse" to a certain extent, and at the same time, because the insulation effect of the room is limited, (just like the ice box, when the set temperature is unchanged, the socks reach the set temperature in the winter refrigerator is very fast, and the refrigerator needs to reach the temperature conditions and time of the next start-up is also very long, but in summer, the refrigerator also needs to reach the same temperature as the winter base filial piety, and the start-up time is very long and the refrigerator reaches the temperature insulation time is also very short, therefore, This has something to do with the ambient temperature) <>
