What is central heating emptying and how to use radiators correctly?

For the central heating system with series connection, there is a very big defect, that is, the heating "emptying" problem, every year when the heating period comes, the downstairs users will have a quarrel with the users on the top floor, because of this problem. So what is heating "emptying", and how to use radiators, let's follow the golden flagship flag brother to find out.

What is central heating "emptying".

The heating period has started again, and the problem of affecting the heating of the radiator for residents downstairs due to the poor "emptying" has begun to appear again, and at this time, not only the downstairs neighbors, including the heating unit, the property company, the residential community, and even the public security department of the jurisdiction can receive help from residents. As for the reason why the "emptying" is not in place, some are empty houses and no one is in charge, and some are "hidden" by the emptying valve during the decoration.

How to use radiators.

First things first: keep the space for heat dissipation.

In order to dissipate heat well, try to maintain a certain amount of space for heat dissipation near the radiator in the room. Do not add a heating hood, do not pile up sundries, and do not get too close to tables, cabinets, sofas and other furniture, one will affect heat dissipation, and the other is easy to burn the furniture.

Secondly: do not open and close the valve at will.

The valve on the heating pipe cannot be opened and closed at will, and when the heating system is first run, the general HVAC company will debug it. The user should adjust the valve to the appropriate position in time, open the manual release valve of the radiator, discharge the air accumulated in the radiator, or open the exhaust valve installed at the top of the system to exhaust until the radiator is warmed up, and the debugging is completed. Once the commissioning is complete, the valve should be fixed and cannot be opened and closed at will.

Again: the temperature should not be too high at rest.

After resting at night, the temperature of the room should not be too high, usually keeping it at 16 -18 is appropriate, so that people will feel more comfortable. During the night break, the temperature of the radiator needs to be adjusted, and the heating system and water supply system of the room can be maintained for anti-freeze.

After the heating is renovated normally, the air inside must be drained for him, so that the radiator can be warmed.

When encountering radiators.

If it is not hot or there is a sound, you need to vent the radiator. So, how to exhaust the air from the radiator, five steps to easily get the radiator to deflate, let's follow Jin Jin to find out.

The first step is to see if the pipe inlet valve is open.

The second step is to close all the valves in your home.

In the third step, when the upper and lower valves are closed, the user gently loosens the gas release valve, and immediately stops twisting the exhaust valve after hearing the sound of gas discharge, so that the gas can be discharged by itself. Since the gases in the radiator are piled up at the top of the radiator, the atmospheric pressure.

Under the effect, it is easy to release the gas.

Step 4: Gently loosen the inlet valve until there is a steady flow of water out, and then close the release valve. You must be patient in this step, just unscrew it a little and hear the sound of water, otherwise the gas will not be easy to discharge.

Step 5: Repeat the action in step 4 several times until all the gas is exhausted. Some users have a lot of gas in the pipes of the radiator system in their homes, which requires repeated exhaust to ensure the stability of heating supply.

In the process of deflating the radiator, many residents accidentally unscrewed the exhaust valve, and the water in the pipes gushed out, and the floors and furniture in their homes were flooded. If the user accidentally breaks the exhaust valve, you can immediately find a wooden chopstick, sharpen the end, and insert it into the exhaust hole to avoid a large amount of water leakage. Then, find a professional to repair it.

The radiator we are talking about is different from the electric radiator or oil tincture, this kind of radiator is mainly through the wall-hung boiler to heat the high-temperature water for heat dissipation, to achieve the effect of heating the indoor temperature, the heat transfer medium flowing in the radiator is injected from the tap water, we will find a lot of small bubbles in the water when we use the basin to connect the tap water, it is conceivable that the radiator system will also bring a lot of bubbles, especially the newly installed radiator, in the initial stage of commissioning, the air in the pipe and the radiator is more, and the air will block the water circulationIt will also occupy the heat dissipation space of the radiator, resulting in the radiator not being able to heat up, so the air needs to be exhausted to heat the radiator, which is one of the reasons why the radiator needs to be debugged.

Radiator air exhaust method:

The radiator comes with a vent valve safety that we can open with a screwdriver by counterclockwise rotation and prepare a small bucket underneath. When a sound is heard, there is water flowing out and accompanied by deflation. When the sound stops, it means that the deflation is complete, and we can just screw it back on.

Precautions: 1. Distinguish between "water discharge" and "gas discharge". Many people confuse radiator deflation with water deflation, but this is actually a false perception.

Putting water on the radiator is a wrong thing to do, not only will it not work accordingly, but it will also cause water to be wasted, leaving the hot water in the heating pipe to be stored insufficiently, which will affect the heating. If there is too much water, it can even cause the entire building to be underheated.

2. Quickly remove the exhaust valve and sakura flush the door. Some people feel that the slow discharge is too slow, so they simply remove the exhaust valve, which will cause the water in the pipes to spray out, flooding their own home and affecting the heating effect of other homes in the same heating system. If this happens, you can use a tool to temporarily block the exhaust valve to avoid a large amount of water outflow, and then call a professional to repair it.

Precautions for the use of radiator round dust

1. The radiator is heated and then transmits hot gas, which requires a certain amount of space. Therefore, when choosing the location for the installation of the radiator, it is not possible to choose a small area. We want to keep the radiator space for heat dissipation.

Do not add a radiator hood to the radiator and do not accumulate debris in front of the radiator. Otherwise, it will affect the heat dissipation efficiency of the radiator.

2. When using the radiator for the first time, the owner should pay attention to the use of details, try to avoid random switching, and carry out a debugging first. Specifically, each household adjusts the valve of each riser to the appropriate position, opens the manual bleed valve of each radiator, and discharges the air stored in the radiator, and then the valve cannot be opened and closed at will after it is fixed.

3. Generally speaking, the installation position of the warm orange song Zen gas piece cannot be changed, and the location should be selected before installation. We give preference to locations that are conducive to air flow, so as to ensure that the overall temperature of the room is uniform. If you change the position without permission, the room temperature may be unstable.

Radiator air exhaust method:

1.Close the valves of all radiators.

2.After making sure that all the valves are closed, gently twist the exhaust valve to expose a gap to expel the tomato gas, you need to be careful not to open it too much, as long as the gas can be discharged, stop twisting the valve, and then wait for the gas in the pipeline to be discharged.

3.Next, open the water inlet valve gently, and you can close the exhaust valve when you see a stable water flow overflowing, and you must also pay attention not to open the water inlet valve too much, otherwise it is easy to flow out a large amount of water and cause waste, which is not conducive to gas discharge.

4.Follow the above steps and repeat the operation to remove all the gas from other pipes of the radiator at home to solve the problem.

Notes:

Exhaust does not solve all the problems of radiators, it can only solve the problem of gas accumulation in the radiator pipes, and problems such as pipe blockage cannot be solved by degassing.

Of course, don't try to deflate lightly, because if the radiator is exhausted in normal operation, it is easy to damage the hardware of the radiator. Finally, when deflating, we must pay attention to opening the valve gently, do not use too much force, it is easy to make the valve fall, which will discharge too much water from Qi Chan, which will have a bad impact on the entire radiator heating system.

Causes of radiator exhaust:

During the operation of the radiator system, there will be gas inside the pipeline continuously, these gases are stored at the highest point of the system, and when these gases are accumulated to a certain extent, the appearance of "gas blockage" will occur, which hinders the activity of water in the system pipeline, and the heat conduction radiator presents the appearance of not heating or heating unevenly, so it needs to be deflated.

Method of exhausting radiators:

Material Required: Rubber tubing.

1. First find the exhaust port of the radiator, which is generally located in the upper right corner of the radiator.

2. Cut a hole in one side of the rubber tube along the red line. (The size should be just enough to be able to put in the heating exhaust vent state Yunshan).

3. After picking the hole, open the exhaust port and quickly hang the exhaust pipe, as shown in the figure. The water and gas will be drained down the pipes. A bucket in the book below is sufficient. Put more gas in the first deflate in winter until the heating is completely hot.

Encyclopedia - Air Blockage.

Radiator exhaust is to alleviate air blockage. The method of venting the radiator is: close the radiator valve, twist the air release valve, and exhaust the gas.

In the whole radiator system operation process, there will be gas inside the pipe continuously, these gases are stored at the highest point of the system, and when these gases accumulate to a certain extent, there will be a "gas blockage" phenomenon, hindering the flow of water in the system pipeline, and the heat conduction radiator is not hot or unevenly heated, therefore, exhaust is an indispensable part of the radiator heating system.

After exhausting, the water flow of the heating system will be smoother, the noise will be lower, the radiator will not form a gas bet, the heating effect will be better, and the water pump will run safer and quieter.

Exhaust method: first determine whether the inlet valve of the heating pipeline is in the state of opening the bucket, close the inlet and outlet valves of the radiator, and gently loosen the gas release valve when the upper and lower valves are closed.

1.Close all valves of the radiator.

2.Open the vent valve to the gap where only the gas can be discharged.

3.Open the inlet valve, wait until there is water coming out, and close both the inlet and bleed valves.

4.Use the same method to drain gas from other pipes.

In order to heat in winter, many families in the north will install heating equipment at home and remove common radiators, which is a device with good heating effect. Anything can go wrong during use, and radiators are certainly no exception. So when there is a problem with the radiator and it needs to be solved by exhausting, how to exhaust the right one?

1.If all the valves of the radiator in your home are open, close all the valves first.

2.Using a tool, gently open the vent valve a little bit, you can expel the gas and then stop the opening, and then wait for the gas to come out on its own.

3.Then open the water inlet valve, but also gently open a gap to observe whether there is water flowing out, when you see a steady flow of water, you can close the valve for air release, and then close the water inlet valve.

4.Since many families have more radiator pipes, you can repeat the above method at this time, and carefully discharge the water from each pipe, so that the radiator heating can be more stable.

Deflating radiators is not a particularly difficult task, you just need to be careful and patient. Of course, the radiator should be based on the cause of the pipe gas accumulation, if it is a heating problem caused by other reasons, then do not use the method of venting at will, because it is easy to damage the radiator. If the heating effect is not improved after the pipeline gas is exhausted, then it is best to find a professional to repair it as soon as possible.
