However, due to the low temperature of the outdoor unit, the condenser will frost. When the air conditioner works for a certain time, there will be a defrosting process, and the frost of the outdoor unit will melt. At this time, there will be water flowing out from the bottom outside, as long as you pay attention.
Of course, the premise is that the air conditioning refrigeration and heating effect is good.
The drain pipe of the air conditioner is the drain pipe of the indoor unit. During refrigeration, indoor air will form condensed water when it meets the condenser of indoor unit. When heating, there will be no condensed water in the indoor unit, and after defrosting, it will freeze outdoors to produce dripping water.
When the air conditioner is heating, there is no water flow in the drain pipe? No, because the indoor air contains moisture and condenses on the refrigeration pipe of the air conditioner when it is cooled. When heating, absorb outdoor heat and blow hot air indoors. The water vapor in the room is not condensed, so there will be no water flowing out.
I hope my answer can solve your problem ~ ~
When the air conditioner is heating, the external machine drains a lot, not the internal machine drain pipe, so it drains water. Why? There is an electromagnetic valve in the air conditioner. When cooling, the external machine is like the radiator behind the refrigerator, and the internal machine is like the condenser in the refrigerator, so it is the internal machine that drains water. When heating, the solenoid valve works in reverse, so it is the water of the external machine. Heating is like the heat from outdoor machines in summer. If there is no electric auxiliary heating in the machine, the heating effect can be basically ignored.
Why doesn't the drain pipe come out when the air conditioning main engine is cooling? There is no condensed water in refrigeration.
Why doesn't air conditioning and heating drain water? When heating, there is condensed water in the external machine, but not in the internal machine.
When the outdoor temperature is low, the outdoor unit may frost, and the air conditioner will frost automatically.
Does the air conditioner keep the hot drain pipe from draining? In summer, when the refrigeration drain pipe is opened, water comes out. This is because the indoor air is hot. When the air conditioner is cooling, water flows out of the evaporator drain pipe of the indoor unit. Refrigerate and absorb the hot air in the room, so that the air becomes water and flows into the water receiving tray, so that water comes out of the drainage pipe.
When they installed the air conditioner, they poured some water into it. That is, do a drainage test after installation to see if there is water or water leakage in the air conditioning drainage pipe. So there is no need to add water.
There will be no water discharged when the heating drain pipe is turned on in winter.
Because the evaporator of the indoor unit of the air conditioner emits hot air, I explain in plain English "changing the phase through the control system;" The air conditioner is cold outside and cold inside. (Water is in the outdoor unit) In summer, the indoor unit is cold and the outdoor unit radiates heat.
Why doesn't Yangzi air conditioner cool? There are many reasons why the drain pipe doesn't come out and the air conditioner doesn't cool. If it is not cooled, users can eliminate it through the common factors that air conditioners are not cooled. If you still can't find the reason within your cognitive range, then you must find professional maintenance personnel to repair it in time. There are several reasons why air conditioners don't cool in summer:
1, insufficient refrigerant
Generally, air conditioners are prone to lack of refrigerant when used for a long time, which is a normal situation. It will not cause the air conditioner not to cool, but will only affect the cooling effect. As long as the refrigerant is added, the problem that the air conditioner does not cool can be solved.
2. The compressor starting capacitor is damaged.
When the outdoor fan is running, the compressor is blocked, that is, the compressor cannot be started. If the voltage is normal (between 200 V and 240 V), it is possible that the starting capacitor of the compressor is broken, so just change it. This kind of failure usually happened the day before, and the refrigeration is not bad, but it will not work today.
3, the power supply voltage is not enough
If the power supply voltage is unstable, it often fails to reach the normal voltage, especially at the peak of electricity consumption, and it is easy for the air conditioner not to cool. Of course, this is not a technical problem, and it does not need professionals to solve it. What is needed is to maintain a normal power supply voltage.
4, the external environment temperature is too high will also lead to air conditioning refrigeration.
This kind of uncooled situation is common when our outdoor unit is installed in a relatively closed space or the temperature around the outdoor unit is too high, which makes the air circulation in the narrow space where the outdoor unit is located insufficient, which easily causes the air conditioner to be uncooled. There is also a common saying that when the outdoor temperature exceeds 43 degrees, it is difficult for most air conditioners to transfer the indoor heat to the outdoor through the radiator of the outdoor machine, which will also cause the air conditioner to be uncooled. The use environment of the outdoor unit can be changed.
5. The air conditioner is not cleaned and maintained for a long time
Failure to clean the air conditioner for a long time may also lead to the air conditioner not cooling. Because the outdoor unit is installed outdoors, after a long period of use, the radiator will absorb a lot of dirt such as dust and garbage, so the radiator has poor heat dissipation effect and the air conditioner will not cool; In addition, long-term neglect of air conditioning maintenance will make indoor air unsanitary, more prone to air conditioning diseases, increase power consumption, shorten the service life of air conditioners, and so on. Clean and maintain the air conditioner so that the clean outdoor unit can dissipate heat later.
6. The copper tube between the outdoor unit and the indoor unit is too long.
Some air conditioners are too long because of the need of installation or unreasonable installation, and the low heat transfer efficiency will also cause the air conditioner not to cool. Try to shorten the length of copper pipe between outdoor unit and indoor unit of air conditioner.
What is the reason why the air conditioner doesn't cool in summer? Besides the six reasons mentioned above, there are many other reasons. When choosing a maintenance company, residents should choose a regular company with a certain reputation. It's best not to trust the phone number and company on the small advertisement. You can call the after-sales service directly. Now domestic brand air conditioners are generally guaranteed for 6 years.
When the air conditioner is cooling, it can't discharge water. Is it because the drain pipe blocked the drain pipe of the air conditioner? 1. See if the cooling mode is set and it starts normally. If the startup is abnormal, the water will not be drained.
The reason why the air conditioning drain pipe does not drain water 2. See if the filter screen is dirty, otherwise it may not drain.
The reason why the air-conditioning drain pipe does not drain water 3. When the temperature is more than 2 degrees lower than the ambient temperature, water will be discharged.
When the temperature difference between indoor and outdoor reaches a certain level, drainage can be formed.
The reason why the air conditioning drain pipe does not drain water 4. The air conditioning drain pipe is blocked. First, open the shell and check one by one to see if there is water flowing out of the joint. If not, open the shell again and see that the hole in the drain is the drain hole. Use a pressurized water pipe or gas pipe to flush or blow air at the water hole. It's really no good, please ask professional maintenance personnel to handle it.
The reason why the air conditioning drain pipe does not drain water 5. There is not enough refrigerant in the air conditioner.
