However, some problems are found in the application process, through the individual for outstanding problems in floor heating system used in the process of research, from design, material, construction and use of the process, find out the reasons and put forward specific requirements and measures, so that we better understand the warm, warm better choice.Keywords: floor; heating; research; Water Leakage1the distribution of water to warm in the marketThe 2009 year, in addition to the northeast water source heat pump market slightly down, all the other regions are growing by over 20%, central China has almost doubled, and in which, Henan became an important basis for the rapid growth in Central China, the product water source heat pump in this area, the growth rate reached 101.7%, which is due to many domestic traditional chiller enterprises are strengthened in Henan water source heat pump market promotion caused by, in the Henan market, including traditional cold water machine group company , Don Han Bush, , with a large number of brands, and so on, in this years water ground source heat pump sales accounted for almost half of their share of overall sales. Northeast of the decline in the market expected, the northeast city of Shenyang has long been identified as the Ministry of construction, Application of GSHP pilot city, affected by this, the entire northeast key area to develop water source heat pump products since 2004, the peak construction period appeared in 2007 and 2008, the year affected the overall the development of the market, the development of water source heat pump products of northeast area tends to be rational thinking, declined sharply to the future water source heat pump can be more mature application in various projects. Different development in the two regions, but also directly affects their share of changes in the market, while other regions share basically unchanged. Northeast because of water source heat pump market decline, directly affect the products in the Northeast market share, in other areas, water source heat pump products share has a certain level of ascension. It is not difficult to see, the water source heat pump products continue to be one of the fastest growing products market in the year 2009, the formation of a sought after in the industry boom, but in the absence of a certain size of the market to support, poured into the water source heat pump market brands will be a severe test.12.Analysis of the development trend of the industry of floor heating and the way outEnvironment, after the baptism of the market, out, integration, the industry of floor heating or grow, or face reshuffle, or already out. For some to innovation, with the core competitiveness of enterprises, regardless of strength, size, or professional ability is strengthened and improve. Due to fierce competition in the industry, changes in external environment, some can not adapt to the industry began to transition, or from the industry of floor heatingSome enterprises began to warm and warm association or around the heating and air conditioning, heat pump, solar energy and other new energy for the development, or to a comfortable living environment, energy saving aspects of development; and in part to product development, production and direction; some enterprises have began to develop energy-saving and contract energy management direction, specializing in energy saving project. To seek change, to seek a breakthrough the bottleneck, heating enterprises through various methods breakthroughs in the development of practical heating industryFuture, may simply heating companies will be less and less, the comprehensive type such as heating, heating and air conditioning, heat pump and other forms of professional heating company, they will be able to provide and satisfy customers various forms of heating, heating and cooling demand, and can provide a more scientific, perfect system and energy saving the solution.Heating enterprises should establish itself and the local industry the road of reform, and strive to be the traditional heating in conjunction with the new social environment and the direction of industrial development, promote enterprise professional level, improve the access threshold for the industry, enhance the industry technical standards, to maintain the industry a reasonable profit space, to ensure that industry, enterprises can be sustained, healthy developmentFirst: floor heating industry development space is very greatAt present, the warm is listed as key national construction projects, because the floor heating than radiator heating, energy saving, environmental protection, health, save the project cost, occupation area saving, simple construction, short construction period, warm tube longevity advantages for 50 years, at the same time to meet the human physiological feet hot head cool requirements, is one of the most advanced heating mode.Floor heating in Canada, Russia, Japan, South Korea and other countries has been widely popular, relatively speaking, floor heating technology is common in China is relatively low. But with the improvement of living standards and the concept of environmental protection in recent years, warm, gradually into the homes of ordinary people, energy saving and environmental protection and health heating mode is more and more families. Floor heating more and more people were like, consistent with national energy-saving emission reduction policies, it is in Chinas flooring market development space is enormousSecond: Requirements for energy saving, environmental protection, comfort, health development of floor heatingChina is a developing country, per capita energy resources are relatively scarce resources, energy and environmental issues has become the restriction factor of urban development, to fully understand the development of energy-efficient type of residential and public buildings, building energy saving, water saving, section, section, is to implement the scientific concept of development, adjusting the economic structure, important content the transformation of economic growth mode, is an important measure for the construction of a conservation oriented society and saving towns, effective from the savings in development resources, seek development from the Protect environment.With the continuous growth of Chinas economy, improve the peoples living level and the level of urbanization and the accelerated, Chinas building energy consumption will further increase. At present our country building housing the annual growth rate of 20%, completed each year an area of 2000000000 m2, of which more than 90% for high-energy buildings; the country has 40000000000 building m2, 95% is high-energy buildings. My unit construction area of energy consumption is 2-3 times higher than in developed countries. Chinese to go the road of sustainable development, the development of energy-efficient construction is very urgent. The Ministry of construction in 2020, the total energy consumption of the whole society to make the building can reach the goal of energy-saving 65%. CO2 emissions reduction of the total energy consumption of the building, is equivalent to the total CO2 emissions in the uk. So the main part of the energy consumption of the building floor radiant heating, energy saving, environmental protection, should be comfortable, health.New energy resources such as the development and utilization of solar energy, heat pump, and the efficient use of traditional energy sources; a variety of energy-saving technologies, energy-saving products such as capillary tube heat exchanger, ice storage technology, storage phase change mature promotion energy technology; to improve living environment, refrigeration, heating comfort dehumidification technology and products; and various related HVAC theory academic exchange activities in the city that the rapid development of domestic construction, the development trend of HVAC industry.Application and promotion of new energy, new products, new technology also increases the power for the development of heating industry. Floor heating, the heating end is combined with various kinds of heat source of the congenital advantage. And, the warm also has the prospect and space applications and the other end forms.Third: Active reference for the development of heating industry in EuropeAs everyone knows that Europe is relatively mature area of global industry of floor heating, heating enterprises in China not long ago to study central heating industry gap, to understand its development is far higher than the China, but as to the market, heating area is the world Chinese heating market in the region - the most potential only three north region is larger than Europe. Half. But at present the north and south of heating the boundaries become increasingly blurred, the area to the south of Huaihe residents heating demand is gradually increasing, but the area and non heating zone, it will warm the personalized heating mode has become the mainstream in these areas. European heating enterprises are optimistic about this point, have vied for Chinese market. The process of warm water China warm market enterprises in Europe, it is our country the same industry to upgrade the good opportunity to warm themselves in learning.23.The application of the south water floor radiant heating In the south the winter temperatures generally within 10 degrees below zero, people think the day is not very cold, that endure winter will pass, but in winter, it makes people feel uncomfortable, out cold, shivering in the home, is to open air conditioning, was not very comfortable, we had the feeling that something warm, but the body (especially the feet) or cold, why? It has a relationship with the air conditioning heating, air conditioning, heating the air inside the room nearby, so that the air convection and heat exchange, continuous cycle. Why it will be a long time, I feel the body will feel warm? Because hot air rises, convection cooling down, the air above the room is always the first heat, only the room all of the air is heated, below the air temperature will make a person feel warm. Only the surface of the human body can feel, but warm to warm foot health philosophy tells us, only the feet warm body can feel comfortable. If the home is the study, the children after school to do homework at home, open air conditioning, first of all is the air conditioner noise buzz sound, and then blowing air convection with the dust breeze, after a period of time after the temperature slowly rising, because the air internal circulation heating can not open the window, when the face warm the air began to feel, turbidity, becomes dry, people appear brain fever foot cold that makes people uncomfortable, so all the phenomena not only let the body uncomfortable, but also affect the child thinking, which influence the effect of learning. In addition people who smoke have experience, if you smoke in an air-conditioned room, as long as a guarantee that no people who smoke are smoked. This method of heating and enjoy a healthy and comfortable living in modern society is extremely disproportionate3Floor heating is low temperature hot water floor radiant heating, especially in our country currently advocate low carbon economy, promotion of household heat metering system and matched by the favor. However, the process of the use of time is not long enough, it is not enough to wide range, especially the design, construction and technical personnel also did not master the skills, operational level should be improved, restrict and affect the promotion of the use of this technology in a certain extent. For the widely used heating technology better, faster, we must understand, analyze related to defects exist, to study and solve the construction, installation, use and maintenance of material quality problem, make use of heating equipment more perfect.4.The floor heating system problems that may ariseBecause of high efficiency and energy saving, the warm comfort of human body strong and so on characteristics, the widespread use of floor heating system in winter housing in Xinjiang area.Heating installed in the floor, does not affect the indoor appearance, no indoor space occupation, convenient decoration and furniture layout, can increase the space for a room, the room is clean and tidy; radiant floor heating household water collector is provided with an independent control switch, each room is equipped with independent set in the water separator, a switch or a temperature by control switch water sets for each room temperature regulation, controllable, and the thermal stability is better.4 However, there are few heating room ground water seepage and even appeared the phenomenon of water, especially in the winter will bring great mental anguish and economic losses to the user, but also to the construction repair units bring certain technical problems; and the more common problem is the floor or hollowing crack, even during use floor crisp produce local collapse; in the housing layout for Cuoceng, housing floor placed furniture or other things more, room of uneven problems.55.Analysis of the problems and solving measuresFloor heating system of the above problems through analysis, the causes are manifold, the system may be unreasonable design, quality materials and equipment is not good, ground cover too much heat can not be dissipated or substandard construction quality and other reasons. Heat supply management and technicians should be aimed at the problems of warm engineering of try to solve seriously, make plan, take measures, and improve the quality of heating. In particular should be strictly in accordance with the technical code for ground radiation heating (JGJl42-2004) and the relevant technical standards of design and construction, to ensure the normal operation of heating facilities. In addition, organize the preparation use the warm sense, so that tenants to master basic knowledge of heating, to remind tenants correctly use the warm.5.1The reason the ground water seepage and measures5.1.1The heating material tube agingThe reason: in particular, individual households directly by external high temperature water radiant heating phenomenon is very common, leading to deterioration of material properties, use a period of time after rupture and leakage of internal and external pressure. Measures: live in purchasing heating material tube, ensure the heating material tube pass. Developers should understand the outside temperature and ensure the use of low temperature water heating in the floor radiant heating; heating material tube should give priority to select high-quality water pipe, PE-Xb pipe, such as, to ensure the pressure resistance, heat resistance, durability. 62.1.2The heating material tube jointThe main reason: heating pipe pre buried before, not in accordance with the drawings accurately calculate each loop length after feeding, produce a joint.Methods: to ensure the construction quality, to avoid the buried pipeline in the joints. Effective measures should be taken to protect the pipe in the process of construction, road laying at the top of the tube, and ensure the stability of the road stand. 75.2The reason of ground cracking and hollowing and measuresReason: in the design of floor radiation heating, usually not on the warm layer of protection setting expansion joint, which makes the floor heating pipe pisolite concrete in after the completion of construction especially the cracks of different sizes in the heating process, the reason, is generally the polystyrene heat insulation layer of the protective layer of concrete the support force is not uniform, resulting in a protective layer cracks, but more is due to thermal expansion of protection layer no leeway and cracked after. In addition, when the length width ratio of the absolute length of floor and the floor of the large floor itself temperature stress, often cracks.8 While the hollowing is due to not take reliable measures of construction, the ordinary concrete, its strength and stability are not up to the requirements of the floor heating system, long time heating situation, some heat accumulation site concrete cushion will have the crack, become one of the common quality of building engineering.Methods: in concrete construction, requires a reliable measure, general requirements of concrete frame wire mesh (for example: 100mm * 100mm20 cold drawing etc.). In addition, concrete variety can using slag concrete or adding expansion agent, in order to increase the stability and heat resistance of the cushion, fine stone concrete pouring, the strength grade of not less than C15, stone size not greater than 12mm, the slag with 30# sieve sieving, curing period of concrete filled layer not less than 48h. At the same time, when the floor area of more than 36 square meters or overall length exceeds 6m, concrete filled layer spacing should be less than or equal to 6m expansion joint, expansion joint width not less than 5mm, slot filling elastic expansion material, at the junction, should be filling soft closed cell foam is equal to or greater than 10mm thickness. The heating coil is arranged flexible sleeve length not less than 100mm across the expansion joint.5.3The temperature uneven reasons and measuresReason: should pass over, water collector will indoor heating pipeline into a plurality of parallel loop of radiant floor heating system, the general should control loop length is appropriate in the 6080m, a maximum of not more than 120m, when the parallel loop length inconsistency especially is more than 20m, prone to disorder because of the resistance difference to water, so that the individual rooms temperature does not reach the design requirements. Especially for Cuoceng housing layout, the situation is more serious; the ground is placed furniture or other things more, covering the ground radiating function.9Measures: Cuoceng housing should cross t
