Historic buildings are very thick solid walls, it can rely on its internal walls absorb the heat. Similarly, in the design of modern architecture can also be extensive use of high comfort, energy saving building structure heating / cooling system. Building structure heating / cooling system through various forms through the combination of cold and heat source, flexible, adaptable to be used in various buildings. Whether used in hot summer or cold winter use, whether in the dry north or in the humid south, this structure heating / cooling system, available through our carefully designed, and is widely used in all the buildings appropriately in. Lai Heng Industrial mainly engaged in environmental science and technology research and product development, currently the world's leading Swiss introduced the structure constant heating / cooling system, set floor heating, cooling and indoor air-handling floor in one pipe through the same set of radiant floor In the summer cooling, heating in winter, and intelligent control and provide a new regional wind, to achieve the most comfortable air environment and saving energy. Ruiheng structure heating / cooling system as a high-tech products, relying on its own merits, is becoming the world's technology leader in air conditioning has become a symbol of fashion honorable life, is widely used in senior housing, villas, and other public places. Ruiheng structure heating / cooling system is a new interpretation of the central air conditioning has to rely on the existing air-based air-conditioning could not match advantage. Ruiheng structure heating / cooling system and the common central air conditioning, the fundamental difference lies in the sense that they regulate the temperature has a fundamentally different starting point. Ordinary central air conditioning through a variety of heating or cooling means the air, and then into the room in the form of strong winds, to the purpose of regulating the ambient temperature; and Ruiheng structure heating / cooling system, means of regulation is to create a cold surface or the floor hot surface of the floor, the floor surface by means of radiation directly to hot and cold and human exchange, but also to all the objects in the room and air heat exchange occurs, eliminating potential cold or heat; in order to achieve the purpose of regulating the ambient temperature. The so-called radiant heat exchange, as we accept the principle of it, like the sun, the sun is a hot object emits infrared energy is passed over beyond, the same hot or cold floor, the floor also have this effect; this heat exchange process is over millions of years of human existence were proven, is accepted by the process of human existence up to the most primitive of the heat exchange process, is the most suitable, the most natural and most comfortable. Although the majority of environmental scientists have recognized the structure of heating / cooling system has the advantage, but because of the floor control condensation and regional technical limitations, has not been successfully developed.
