In the winter, the temperature is getting lower and lower, but it is better to concentrate heating in a week. At present, most communities use geothermal heating, and there are some misunderstandings about the use of floor heating that require our attention.
Myth 1:
When the floor heating is on, it will rise sharply.
The correct way: the floor heating will be heated after 24 hours, and the temperature will rise by 1 °C for one hour.
The heating is coming, isn't it hot? Some owners have been rushing to turn the thermostats high on the first day of the heating. The owners without the thermostats are anxious to call the property. "They are still not hot, and they are heating up quickly." ". Liu Mingyu, head of Shaanxi Tianxin HVAC Equipment Co., said that the floor heating should not be too fast, especially in the early stage of heating.
The floor heating temperature suddenly rises, which will bring certain adverse effects: First, it will cause great pressure on the floor heating equipment and affect the service life of the pipeline; second, the ground temperature will rise too fast, which will affect the floor material, and the wooden floor may appear locally. If it is deformed, the floor tiles may have cracked enamel. Third, the furniture on the ground may also be affected by high temperatures. It is recommended to gradually warm up after 24 hours of warm-up, and the adjustment of 1 °C in one hour is the safest.
Myth 2:
The higher the indoor temperature, the better.
The correct way: the most suitable temperature is 18 ° C ~ 25 ° C, if it is too high, you have to lower
Floor heating can not be heated quickly, and the temperature can not be adjusted too high, too high temperature is not conducive to human health. The optimum temperature for winter indoors is 18°C~25°C, and the relative humidity is 40%~70%. At this time, the human body feels most comfortable.
According to Chu Zhongming, the head of Shaanxi Ruimei HVAC Equipment Co., Ltd., the temperature standard for winter heating in China is based on people's physiological needs. The national standard GB50019-2003 "Design Code for Heating Ventilation and Air Conditioning" stipulates The standard indoor temperature for heating is 18 °C ± 2 °C. Related medical research has also shown that if the surface temperature is too high, it may cause blood vessels to dilate, leading to a variety of diseases.
If the indoor temperature in winter is higher than 25 °C for a long time, it is recommended to lower the temperature. For example, if the room temperature cannot be adjusted, it is recommended to open the window to dissipate heat, and pay attention to indoor moisturizing.
Myth 3:
No pressure test before heating
The correct approach: the pressure test should be carried out before heating every year.
Many owners believe that after the renovation, the floor heating pipeline has been subjected to pressure suppression experiments, or that it has been over pressed last year and will not be used this year.
In fact, after the temperature changes in the four seasons, some physical changes will inevitably occur in the equipment. Chu Zhongming recommends that the floor heating pipe be tested before the heating every year. After the heating is finished, drain the water from the heating pipe.
The specific steps of the pressure test include: the first step, slowly injecting water through the water separator, and discharging the air in the pipeline; the second step, after filling with water, performing watertightness inspection; the third step, using manual pump to slowly boost; fourth Step, after boosting to the specified test force, stop the pressure and stabilize the pressure for 1 hour to observe whether there is water leakage. In the fifth step, after 1 hour of voltage regulation, the pressure is applied to the specified test pressure value, and the pressure drop within 15 minutes does not exceed 0.05Mpa is not leaking qualified.
Myth 4:
Furniture has no effect on the floor heating
The correct way: furniture attached to the bottom plate will affect heat dissipation, try to place leg furniture
Many owners believe that the floor heating is mainly related to the ground, and the furniture on the ground should not affect the operation of the floor heating.
Mr. Yan, an engineering staff member of Xi'an Longhu Property Company, said that many owners use a lot of legless furniture at home, and the furniture is directly attached to the floor. In fact, this has a certain impact on heating.
If the interior is heated by floor heating, do not make fixed decorative parts or legless furniture with a large area on the floor. Because the floor heating floor is a cooling surface, the hot air circulates from the bottom to the top, producing a greenhouse effect. If the legless furniture is placed on the floor, the heat dissipation surface in the room will be reduced, which not only causes the heat effect to be weakened, but also does not allow the heat to be sufficiently dissipated.
