1. "Is the name of the dedicated geothermal floor right?"
In the current floor circulation market, the floor for floor heating is not only a wide variety, but also has a more chaotic name: such as “heat-resistant floorâ€, “resistance to floor heating floorâ€, “ground heat-resistant floorâ€, etc., the most shouted is “heating floorâ€. "Ground heating floor", "heat-resistant floor", "geothermal floor", "dedicated floor heating floor", etc., we think that some names are unscientific, and some names do not seem to be appropriate. At present, especially the ground radiant heating system is in the early stage of development, the name must be Standardization, it should be said: "floor heating floor" should be defined as: suitable for the floor of the radiant floor heating system, and through the board to the room to transfer heat.
2. “Where is the floor suitable for floor heating?â€
“Your floor can be used to heat the floor?†The purchaser replied: “There is no problem, the geothermal special floor.†Almost every floor sells such a very positive answer, but also takes out user examples, and some still Taking out the test report, the consumer feels, “Where the floor should be used to warm the floor.†It is not known that the floor heating should meet four major factors: ground heating conductivity, dimensional stability, anti-fouling and environmental protection, and durability. The flooring industry is developing floor standards to quantify the four elements, and to develop quality inspection specifications for floor exhibitions and warranty periods, so that the technical indicators for exhibition and maintenance are also quantified.
3. "The thicker the floor, the more insulation?"
The thickness of the wooden floor is a factor in determining whether the foot feels comfortable, so many consumers require a thickness of 15-18 mm when purchasing the floor, especially when purchasing solid wood, multi-layer solid wood flooring or bamboo flooring. Therefore, when purchasing floor heating, they also use this method to select, but it is not known that wood is a poor conductor, usually the thermal conductivity of wood material is between 0.17-0.34, and the water is 0.5. If the thickness of the floor is too thick, it is even more detrimental to the conduction of heat through the floor to the surface of the board, and it is consumed in the conduction process. As for the heat preservation, the temperature difference between the upper and lower floors is very large, which will inevitably lead to a large deformation of the floor. "The thermal expansion and contraction" and "swelling and shrinking" will cause the floor to be scooped, twisted, bent and cracked, and the dimensional stability cannot be guaranteed.
4. “Is the geothermal heating floor specification too wide?â€
Now consumers buy solid wood flooring for the comfort of life, and second, to show their identity. Therefore, when purchasing, it is often preferred to select those with larger specifications, especially in the width direction, and some can reach 180mm. Such a width, in the daily floor display, experts do not recommend the user to buy, so as to avoid the seams due to the swelling and shrinkage of the floor, not to mention the fact that in the case of heating the floor, because the water is emitted faster, it is even more The phenomenon of floor separation is easy to occur. Therefore, experts recommend that consumers should not buy oversized floors when purchasing geothermal heating floors.
5. “Can you only manage the suspension?â€
Due to the special structure of the geothermal heating system, the concrete floor cannot be nailed when the floor is displayed. Therefore, most of the exhibitions of geothermal floor have long been recognized as suspension exhibitions. In fact, with the continuous advancement of technology, there are two other methods of exhibition: floor bonding and keel exhibition. Recently, there has been a kind of quick-loading keel on the market. This keel can be fixed without fixing the keel. The keel can be directly fixed on the concrete floor with glue, and then the floor is fixed by the buckle on the keel. On the keel. This not only increases the feel of the floor, but also allows space to convect the air up and down due to the space between the keels, which is conducive to the circulation of heat, and makes the floor more evenly heated, with less deformation and higher thermal efficiency. This is a highly regarded approach to the current value.
6. “Can I add plywood or blockboard under the floor?â€
First of all, plywood or blockboard is displayed under the geothermal heating floor, which is not conducive to the conduction of heat. Invisibly increases the heat loss during the conduction process and increases the heating cost of the geothermal heating system. Secondly, if the quality of the purchased plates is not good, it will lead to excessive formaldehyde content in the room, or because the water content is not up to standard, the moisture will be absorbed by the floor after the exhibition, causing the floor to become wable and arch. In addition, this substrate board has many disadvantages, and it can be said that it is self-defeating and superfluous! It is not allowed to show the floor under the floor.
7. “Is the floor mat with aluminum film dedicated to the floor heating floor?â€
This is the most typical misleading. Practice has long proved that in the ground-radiation heating system, the heat transfer is mainly radiation, followed by convection, and finally conduction. If the aluminum foil is covered on the heat-dissipating ground, the anti-radiation is formed, and the surface temperature is the same while maintaining the floor heating temperature. Under the foam pad with aluminum film, the thermal resistance is large, while the ordinary foam pad has small thermal resistance. Obviously, the ordinary foam pad has better heat conduction effect than the foam pad with aluminum film, and is more favorable for heat conduction from the floor to the living room. Therefore, when purchasing a floor heating, the user should select a material cushion with small heat resistance, moisture resistance and corrosion resistance.
8. The floor is not finished with the floor heating test.
After the installation of the geothermal heating floor, in addition to the routine acceptance of the inspection, the most important thing is to check the temperature of the floor. After the floor display is completed or warmed after winter, the first time the floor heating system is warmed up, it should be slowly warmed up. When the base floor is heated to 25 ° C, it should be kept at a constant temperature of 12-24 hours. After that, slowly increase the temperature to 1 °C / h to the required indoor temperature (14-22 ° C), the temperature should not be too high, the wooden floor surface temperature should be ≤ 28 ° C. In a short time, the limit temperature ≤ 32 ° C, the higher the temperature, the thermal energy loss is too large, the shorter the thermal system life, easy to occur hidden danger, and the floor is prone to scoop, twist, bend, crack and other deformation.
9. The floor is not finished with environmental protection.
Since the floor used as the floor heating system is mostly composite floor (solid wood composite, reinforced and bamboo wood floor), it has the problem of formaldehyde emission, and when it is used as a geothermal floor, after heating, the formaldehyde is more played. freed. Therefore, after the installation of geothermal heating floor, it is necessary to carry out environmental protection acceptance, to ensure that the release of free formaldehyde reaches the standard (1.5mg/L national standard), in order to make the floor can be used normally, be sure to do two when purchasing Point: 1 Before the floor heating floor should be used for environmental testing, the general test is free, management should be charged, and then tested for environmental protection. 2 Floor and accessories environmental indicators must meet the standards. You can't buy cheap bargains that are not environmentally friendly, or you will endless troubles!
10. Place a legless combination of furniture or carpet on the floor to destroy the floor cooling surface.
With the continuous improvement of the living standards of modern people, people are increasingly pursuing individualization for home decoration, so many personalized assembly furniture have emerged, which can be assembled according to the owner's preferences. However, these pieces of furniture are often legless furniture with the bottom layer directly in contact with the ground. If the indoor exhibition is equipped with geothermal heating floor, the large area of ​​furniture and carpet will be directly covered by the floor, which will make the floor cannot be scattered due to heat, and the floor will be unevenly heated, resulting in uneven deformation of the floor. Waste heat energy to lower the temperature of the living room.
