Ground heating is the abbreviation of floor radiation heating. It takes the whole ground as radiator, heating the whole ground evenly through the heat medium in the floor radiation layer, and conducts heat from the bottom to the top by using the heat storage of the ground itself and the rules of heat radiation upward, so as to achieve the purpose of heating. So will the ground warming be uneven? Now let's get to know it together.
The floor heating system will be designed according to the heat preservation, heat dissipation, room function, furniture placement, choice of ground laying, and adjustable heat source of different rooms. Therefore, the floor heating system will not be subcooled or overheated in general. Additionally, the control system of different equipment will make different rooms reach comfortable temperature.
But when many users do floor heating, they are worried about the future temperature and ask the company to reduce the distance of buried pipes. Many companies cater to users'ideas blindly. As a result, the heating pipes are laid too densely and the whole or part of the room temperature is too high.
Now all kinds of qualified solid wood flooring, solid wood composite flooring, reinforced wood flooring, stone, tile, linen carpet, wool carpet, cement brick, rubber floor and floor leather can be used for floor heating. Only the thermal conductivity of different floor materials is different, so we should inform the heating company of the decoration materials to be selected before the heating device, so as to take into account the heat load calculation.
The filling layer of the floor heating device plays the primary role of accumulating heat to balance the surface heat, maintaining the heating pipe, heating fast, together with good effect on floor maintenance. Because different customers install different filling layers of floor heating, many people think that the primary reason why floor heating is not hot is that the filling layer of floor heating is not thick. So, what is the specific reason? Let's understand the relationship between the heating effect of the floor heating and the filling layer.
Filling layer has a certain thermal insulation effect, so it is necessary to have a certain thickness. The thicker the filling layer, the greater the heat storage, the greater the thermal inertia, the better the thermal stability, while the initial temperature rise is slightly slower. The study shows that the heat stored in the filling layer is related to the thickness of the filling layer. Because the thickness of the filling layer not only affects the normal heating function of the floor heating system, but also directly affects the net height of the room, the load of the structure and the initial investment cost of the building, so the filling layer should not be too thin or too thick.
Of course, the time when the filling layer reaches the required temperature is also related to the thickness of the filling layer: the thicker the filling layer, the longer the time when the filling layer reaches the required temperature.
Therefore, the thickness of filling layer in Geothermal Engineering is closely related to the time of heat storage: the thicker the heat storage layer is, the longer the heat transfer journey upward, and the longer the time required to reach the indoor design temperature, that is, the slower the temperature rise; but from another point of view, the thicker the filling layer is, the larger the volume of backfilling layer is, the greater the heat storage of the heat storage layer is, and the ground temperature is inert. The bigger the property, the longer the delay time and the better the thermal stability.
