Why does the stove pour smoke when the window is closed

The use of air conditioners to close windows and doors is to make the room with air conditioning form a relatively closed space, the operation of the indoor unit fan of the air conditioner makes the air in this space circulate through the indoor unit, and in the process of circulation, the refrigerant of the air conditioner absorbs the heat in the air and blows out the cool air that has lowered the temperature, and the temperature in the room continues to drop due to the continuous circulation of this process. Until the equilibrium point (the temperature you set) is reached, the compressor stops (or the speed is reduced for inverter air conditioning compressors). But because this room is relatively closed, there will be some outdoor hot air into the room and the heat emitted by the people in the room and some other reasons make the temperature of the room slowly rise, when the temperature is higher than the temperature you set, the compressor will run again (inverter air conditioner is the compressor running at high speed), and then circulate the air in the room to cool down. This repetition allows the room to be controlled within the temperature range you set.

However, if the windows and doors of the room are open, the indoor and outdoor will form an open space, and the cold air blown out by the air conditioner will quickly absorb the heat in the air, because the window or door is open, the outdoor hot air will continue to enter the room, so as to form a large circulation, and the outdoor hot air you can not be able to cool down, so it will cause the temperature of the room using the air conditioner to drop to the temperature you set. As a result, the compressor cannot be stopped (running at high speed) and is always in working condition. The most power-consuming component of an air conditioner is the compressor, and the compressor works non-stop and is doing "reactive" work, and the electrical energy consumed by it is also consumed in vain, that is, it is wasting electricity. Oh.

It has something to do with the direction of the wind, just install crooked foil.

Most of the reasons why the stove pours smoke into the house are that the outlet circulation is not smooth, and if the furnace barrel is not blocked, it is a problem with the outlet. You can press a tee at the mouth of the bright potato to prevent air backflow; Or the furnace drum with a heightened outlet, and one or two more furnace bobbins above the tee of the outlet are conditionally added, so that they are not disturbed by wind or reverse air. The indoor bobbin installed from the stove upwards should not be higher than the outdoor outlet, and the outlet must be higher than the height of the indoor vertical bobbin.

In the case of smoke from the furnace, you can pay attention to the following points to keep the coal stove unobstructed:

1. The ash under the furnace must be cleaned to allow it to circulate well.

2. Check whether the flue is blocked and dredge the flue in time.

3. Check whether the chimney mouth is windward. Smoke guess the key chimney facing vertically upwards and use the chimney cap appropriately (30cm high).

4. Check whether there is a baffle at the chimney mouth, and if so, it should be cleaned up in time.

5. Check whether the vertical height of the chimney is up to standard, if the chimney is too thin or not high enough, the chimney should be replaced in time.

6. Check whether other equipment that can reduce extraction is installed on the chimney, such as range hood. If there is, dismantle.

There are two situations when the raw stove pours smoke back: one is because the flue of the bridge is not smooth, and the other is windward, the wind is blowing to the flue, and when the stove pours smoke, you can check whether the smoke is blocked, dredge the flue in time, and you can also check whether the chimney mouth is windward, and the chimney should be vertically upwards and use the chimney cap properly.

The stove can check whether there is a baffle at the mouth of the chimney, if there is one, it should be cleaned up in time, and you can also check whether the vertical height of the chimney is up to standard, if the chimney is too thin or not high enough, the chimney should be replaced in time.

Factors such as smoke leakage from residents' chimneys, poor sealing of coal stoves, and wind backfilling are easy to lead to carbon oxide poisoning, and the chimneys should be cleaned frequently, to avoid blockage, to prevent smoke from backing, and the stove should avoid communication with the bedroom.

The flue gas of the gas burning appliance should be discharged to the outside through the flue, and when multiple equipment share one flue gas discharge, the flue should have a good anti-backing smoke and anti-string smoke function, and the horizontal flue should not pass through the bedroom.

Summary. Why is there smoke when the stove is closed? Everyone knows this, and when the door is open, there will be a lot of oxygen, and the air will come in.

The combustion is more sufficient. There is basically no smoke. Close the door, and the oxygen won't come in later.

Burning becomes slow. It will cause a lot of smoke.

Why is there smoke when the stove is closed? Everyone knows this, and when the door is open, there will be a lot of oxygen, and the air will come in. The combustion is more sufficient.

There is basically no smoke. If you close the door, you won't be able to get oxygen in the future. Burning becomes slow and balanced.

It will cause a lot of smoke.

When the stove is closed, there is smoke, and the door is not opened.

If you want to solve the problem of smoke coming from the stove, the only way to do this is to add a chimney to him. Increase the pumping force of the chimney. This will completely solve his smoking situation.

Stove chimney smoke back-up situation solution:

1. The smoke exhaust of the noisy coal grate is carried out by "chimney extraction". The magnitude of the pumping force is equal to; "Severity of cold air" minus "severity of flue gas" and then multiply by "height of chimney", normally the chimney is able to exhaust the flue gas.

2. Causes and corresponding methods of smoke inflow:

a. The height of the chimney is not enough, and the suction force generated is small, especially when the air pressure is low, the advection wind may fall back from the chimney. The solution is to add a pure high chimney or a windshield that can be adjusted with the wind direction.

b. The chimney air leakage will reduce the suction force, and the corresponding method is to wipe a liter of cover to close the gap and block the air leakage;

c. When the furnace is ignited, the smoke is poured because the chimney suction has not yet been formed, the more horizontal the flue is long, the slower the chimney is formed, and the horizontal flue will be made into an upward slope.

d. Increase the induced draft fan in the exhaust flue.
