Warm this heating method favored by people like, especially in the North region, Inner Mongolia, the three provinces in Northeast China, including Beijing, since 2006 in the building and the new community and 60% chose warm. The technology not only in foreign countries is used extensively for residential and various medical institutions, swimming pool, gym, shopping malls, office buildings and other public buildings, and is used extensively for workshop, hangar, flower bed, football field and greenhouse, building systems and thermal insulation, even for outdoor road, roofs, stairs, airport runway snow melt and various industrial pipeline insulation. At present in Europe and developed more than 50 per cent of the new buildings are radiant floor heating system. With a deeper understanding on floor heating, the editor has collected some knowledge related to warm for reference.
Warm and comfortable home
The advantages of a, floor heating
Warm comfort is one of its greatest strengths, it's comfort the indoor surface temperature mainly comes from the bottom up as at a uniform height increases the temperature gradually declining, this temperature curve fits the needs of human physiology, feet warm head cold comfort. Chinese medicine believes that "the heat from the ground, cold from the foot-in". Modern medicine has also demonstrated that the body's internal organs and only in appropriate temperature conditions, in order to maintain normal physiological functions. When the outside cools automatically adjust the functions of the human body, in order not to make the body heat loss, his blood will flow back to maintain the internal organs, the desired temperature. When the foot temperature low, foot vasoconstriction, blood flow is blocked, causing systemic blood circulation is not smooth, so that the people of the whole body will feel cold. So warm people have to warm feet, feet warm, and the whole body will feel warm.
Traditional heating way, room of approximately 30 ° c at the top, and body position especially foot only 15 ° c or even lower, sitting over time you will feel feet cold cold cold, thigh and leg increases cold leg disease, arthritis diseases. Floor heating can promote occupant foot blood circulation, thus improving systemic blood circulation, promote metabolism, and to some extent, increase immunity. "Foot thermal head cold" environment can avoid sleepy, conducive to enhanced memory, learning and working efficiency. The elderly and children in the family would have no hesitation in choosing floor heating.
At present, China's floor general use prefabricated or slab, its noise is extremely bad, people walk upstairs, downstairs, affecting the floor heating increased insulation, with a very good sound insulation effect, reduces noise pollution; floor heating process is silent, quiet indoor environment, no air conditioning noise, which helps children to focus on learning, thus it¡¯s helpful for improving the efficiency of learning.
II. origin of floor heating
Radiant floor heating is not mysterious, early in the year 1300 b.c., Turkey Royal palaces in the embryonic form of radiant heating, BC 80 years, the famous Roman bathroom floor heating to "fire" in the form of, in the Northeast still in use by the application the huokang is floor heating the principle of
In the 1930s, the famous United States architectural design master Mr. in its design of a large number of works with radiant floor heating, greatly promoted the application of floor heating, but because at that time you can only use copper tube as a heating coil, not only expensive, but corrosion caused by leakage of maintenance cost is high, resulting in application of radiant heating was very limited. Until the beginning of the 1960s, anti-aging, high temperature, high pressure, easy bending of the plastic tubing to practical application, this situation will be changed. Cheap, underground tube no interfaces, the tube wall is not easy to scale, long life and other advantages of the plastic tubing, greatly facilitated the radiant floor heating technology promotion and application.
