Video Tutorial Link How to Drain Water from Geothermal Heat: Web Link
How to Drain Water from Geothermal Heat is as follows:
1 . First we prepare one. plastic pipe and insert it into the purge valve, then open the water inlet valve and close all other valves.
2. Open the water dispenser deflation valve and enter the water pipe, then deflate it for the first time until the released water no longer contains bubbles and close it.
3. Open one of the water inlet and return valves of the water dispenser, then open the air discharge valve of the inlet pipe of the water dispenser until the released water does not contains more bubbles.
Fourth, follow the above operations until all the branches are deflated. After deflation, we open the ventilation valve of the geothermal return pipe to discharge the water.
Precautions forr release geothermal water before heating
1. It is not recommended to release too much geothermal water. In principle, only drainage is permitted and water must not be released. However, the exhaust will release a small amount of water, this is a normal phenomenon. Generally speaking, you will hear a “vacuum” sound as soon as you unscrew the valve. This means there is air in the geothermal pipe. If you continue to let it in, you will see water coming out "puch-plop-plop". " until there is no more plop-plop sound. Just let the tap water flow like this.
2. The number of drains can be from one to twice per heating period The number of evacuations is directly related to the heating Geothermal valves are usually found in the kitchen or living room, the heating and when the heating stops quickly. , the heating time is short and the pumpcirculation pe and the heat exchange station are also stopped, which can easily cause air blockage. Therefore, you usually need to expel more air. , just exhaust the air completely once. When using underfloor heating later, the air should only be released once or twice during the entire heating period.
The damage caused by underfloor heating is not real. Thermal radiation from underfloor heating will not cause damage.
The reason why the word "radiation" appears in underfloor heating is to emphasize that its main method of heat transfer is "radiation heat transfer", which is different from radiation to which people pay attention every day. Thermal radiation is a very common natural phenomenon, including heat dissipation of human body temperature by radiation. Radiationt thermal underfloor heating in your home is not harmful.
Detailed information:
Underfloor heating is short for “underfloor heating radiant through the ground.” At present, the market There are two types of floor heating on the market: electric floor heating and water floor heating, and most of them use hot-water floor heating. water.
Water underfloor heating is low temperature hot water radiant underfloor heating. It uses hot water with a temperature not exceeding 60°C as heat transfer fluid. It circulates through the heating tube to heat the soil and transfer it. heat by radiation and convection through the ground. A heating method that provides heat to the room.
“To use a popular analogy, the water underfloor heating method is like using a hot water bottle. It only radiateshas water temperature in the room, so it does not harm the human body. Additionally, water underfloor heating uses radiation. The statement is not particularly accurate. It is more accurate to say that thermal conduction is more precise”
Objects in nature will emit thermal radiation into space and indoors. at the same time, continuously absorbs it.Thermal radiation emitted by other objects allows heat transfer between objects. It can be seen that thermal radiation is only a means of heat transfer, and only thermal radiation can propagate through a vacuum. Sunlight is also transmitted to the earth by thermal radiation.
