The modulation of heat in cold sky is not effective.

In the cold wind in winter, how to prevent cold has become a key issue. But many people know that the air conditioner we often turn on in summer has the function of heating besides cooling. Some people often have some doubts about heating. Today we will analyze seven problems, hoping to help you.

1, why the colder the weather, the worse the heating effect?

A: The main reason is that the colder the weather, the lower the outdoor temperature, and the more difficult it is for the air conditioner to absorb the heat of the outdoor air environment, resulting in relatively poor heating effect.

2. Why is it recommended to use other equipment for heating when the temperature is below -5 degrees?

Answer: In winter, when air conditioner heats, it absorbs the heat of outdoor air through the heat exchanger of outdoor unit, and then transfers the heat to the room through the heat exchanger of indoor unit. Meanwhile, when heating, the outdoor heat exchanger is used as an evaporator. When the outdoor temperature is lower than -5 degrees, the temperature difference of heat exchange between condenser and outdoor air will be close to 0. Therefore, there is no heat exchange effect, which leads to poor thermal effect of the air conditioning system and even no heating. Therefore, it is necessary to turn on the auxiliary electric heating function of the air conditioner or adopt other heating equipment.

3. How to judge whether an air conditioner is heating normally?

Answer: The standard of air conditioning refrigeration and heating inspection: After starting 15-20 minutes, measure the temperature at a distance of 10-20 mm from the indoor air inlet and outlet. The temperature difference between the air inlet and outlet should not be less than 65438 00℃ during cooling and 65438 05℃ during heating (heat pump air conditioning).

4. Why can't the temperature of the air outlet represent whether there is something wrong with the machine?

A: The temperature of the air outlet of an air conditioner cannot be used to judge and measure whether an air conditioner is normal. The standard to judge and measure whether the air conditioner is normal or not is mainly based on the temperature difference between the air inlet and the air outlet of the indoor unit when the air conditioner is heating. As long as the temperature difference between the air inlet and the air outlet reaches the standard, it can be judged that there is no problem with the air conditioner.

5. Why is the air conditioner on all the time? To a certain extent, why is it difficult for the temperature to rise?

A: The room temperature is low, so the improvement of room temperature by air conditioning and heating is more obvious. With the increase of room temperature, the difference between indoor temperature and outdoor temperature increases, so the more heat is transferred from indoor to outdoor, and the increase of indoor temperature will slow down. When the temperature difference reaches a certain level, the heat generated by the air conditioner is just transferred to the outside and neutralized, so at this level, the temperature will not rise again.

6. Why is the indoor unit not running and the outdoor unit running when heating?

A: Heating and cooling are just the opposite. The work of the indoor unit and the work of the outdoor unit are interchanged. When cooling, it is indoor running water, but when heating, it is just the opposite, that is, the outdoor unit produces water, but the produced water does not form condensed water to flow down the condenser fins, but forms frost attached to the fins (mainly caused by too cold ambient temperature), which can only flow down after defrosting and melting for a certain time.
