Warm laying pay attention to what [Date: 2014-5-27 Author: admin Hits: 9] [Return] Q: to warm the laying pay attention to what? A: According to Special to the Jedi tube warm years of construction experience, whether it is warm water or electric floor heating, should pay attention to are: 1, the ground must be dry, flat, larger uneven cement mortar chipping and required to be corrected tolerance is not greater than 0.5cm. 2, the site of debris, construction waste has been cleared. Consolidation and warm it is not within the line independent heating zones. 3. All wet work inside the building have been completed and fully dry after; carpentry cleared after recommendations were warm laying, carpentry avoid damage to the warm parts. 4, insulation to ground floor flat on the ground, overlap closely. Pawn shop when a single layer of aluminum foil veneer layer can not be damaged. 5, floors and some have thermal expansion and contraction phenomena laying surface coverings, should set aside a certain amount of expansion joints. 6, ground sheet if the choice of flooring, it must be resistant to heat dedicated floor or laminate flooring, we recommend ceramic stone wood floors, wood floors should not be used, so easily deformed. 7, home improvements carried out considering the overall design and determine the location of the thermostat. Each specific location of the room thermostat can be determined based on the owner's preferences. In general, the thermostat installation height with indoor light switch same as about 1.2 to 1.4 meters. Q: to warm the laying pay attention to what?

Each specific location of the room thermostat can be determined based on the owner's preferences. In general, the thermostat installation height with indoor light switch same as about 1.2 to 1.4 meters. What warm considered good warm? Q: What constitutes a good warm warm? A: Good to warm should be like this: First, look at the heating effect: heating up fast, uniform horizontal temperature gradient perpendicular to the direction of temperature, to give the most comfortable feeling better warm. If the half-day warming up, or the temperature East hot sirloin, seriously affecting the heating comfort, this is not acceptable. Second, look simple handling operations, the best smart thermostat, you can freely adjust the temperature in each room; if not free to regulate the temperature of each room, which will increase the use of fees. Third, look at the cost thermal efficiency conversion rate, saving energy to warm the product better and better products cheaper energy costs. Fourth, look at maintenance costs and maintenance costs are too high, people do not worry product. Such as how to maintain product every year, some for decades without maintenance, better, a comparison came out. Fifth, look at the product structure is simple to install, easy to install floor heating products relatively better because of a complex, installation of complex products will inevitably lead to a certain degree of risk exists, if there are problems, maintenance is very troublesome. Complicated installation, if not handled properly could also security risks. Sixth, to see if the space does not occupy space, does not affect the story or fishes little story to warm the better effect, such as some less than 2.7 m storey house, if you take up warm 10cm, the house is only 2.5 effective layer m multi-point, which will warm the home uncomfortable. Seven, to see whether the environmental pollution, no noise, no emissions, no radiation will not pollute the environment to warm products better. Eight, look good security security, no security risk to warm the product that people can safely use. Nine life terms for warm, a few years on the problem of the product is certainly not good. For instance, some can be used for several decades, and some a few years, who do you think is good? Introduction warm temperature hot water heating and warm water from the hot water temperature no higher than 60c for the hot medium circulating in the heating pipe, heating floor, through the ground to radiation and convection heat transfer to the interior heating heating method. The indoor temperature can be adjusted manually and automatically adjust the heating thermostat reached by set manifold. Commonly used as a heat-resistant polyethylene pipe PE-RT pipes, polybutylene PB pipe. Heating cables heating cables to warm cold warm is electricity for energy, low temperature heating cables for the heater, heating floor, through the ground to radiation and convection heat transfer to the interior of the heating mode. Indoor temperature to achieve through manual control or intelligent control to achieve constant temperature heating thermostat. Thin Thin warm water and electricity, multi-floor heating system is on a general purpose polystyrene by an international special setting high-density insulation board and high thermal conductivity of aluminum as a special groove metal substrate, according to the requirements of the living environment paving using two methods, First, wet installation, the heating pipes or heating cables directly insert into the groove thin floor heating insulation template. Second, dry installation, which in the thin insulation template above pre-laid metal thermal plate, and then heating pipe heating cables combined module inserts into a recess, heating pipelines and storage layer by rapid and uniform heat conduction radiation, so that the indoor temperature in the shortest time to reach the optimum body temperature. Far infrared radiation electric heating film heating film is energized latter can heat a transparent polyester film. The conductive carbon fibers can be a main component of the ink, metal carrier, as amended, processing, hot pressing between the insulating polyester film. Unlike conventional electric heating wire. With electric film heating element, the heat. In order to form a uniform surface emission into space, people feel the warmth of the sun. Far-infrared heating film in the United States and Europe began 20 years ago through the use of proven products. Common sense to warm to warm water leakage it? Warm laying pipelines buried part of the whole pipe, with no joints, all pipe joints are in the trap. General on the toilet trap layers, usually with only one component level villa water heater (for floor area is not great), as long as the proper selection will not have leakage problems. Floor heating system must be replaced every year new water? Warm water is no need to replace the system, if replaced with new water every year, it is easy to produce scale. Because the knot scale water and difficult to continue scaling. Floor heating is easy to use furring? Floor heating is a low-temperature radiant heating, heating water temperature below 60 ℃, general heating water temperature is about 50 ℃, the temperature of the water shortage scaling point, the use of floor heating easy to produce scale. Use warm saving it (for the independent heating customers)? In the case of meet of Thermal load, reasonable design, construction, floor heating energy saving should be at least more than one quarter. This is because the land belongs to the low-temperature radiant heating warm, most of the heat will be concentrated in the region who need ground, the foot of the most warm, cooler head, that is hot on a cold indoors under, which is exactly in line with human needs. Floor heating and air-conditioning mode is exactly the opposite way Convection heating, convection heating heat concentration roof top, the coldest in the region, the heat under the cold. Which floor most energy? Brick, stone most energy, followed by wood flooring (wood flooring), carpets worst heat. What are the advantages of floor heating? Comfort: head cold feet warm without drying, feels like spring sunshine. Health: meet the human needs, and human health theory. Energy: less heat loss, independent heating customers significant energy savings (if it is reasonable to design and installation) Environmental: radiant heating mode dust flow is small, do not smoke wall interior clean. Do not take up space, no noise, the service life of 50 years, an investment lifetime. There are ways to control the temperature to warm? The most basic temperature control methods: sub-valve on the water to warm through, adjust the water flow control indoor temperature of each room. Automatic temperature control: temperature control with room temperature. Remote control: control in advance by phone or computer to warm temperatures in various regions (for life without the law, often away on business customers).

Due to human causes, not resistance, improper operation caused by the failure, the company provides paid services. Warm pipe market application status last year, different brands of electric pipe companies in the fierce market competition, while different types of floor heating pipe itself is undergoing a "self-transformation." From the number of production and PE-RT pipes PE-Xa pipes to warm the pipe mainstream business point of view, the current PE-RT pipes in floor heating pipe production and marketing chain are dominate. PE-Xa pipes early in the last century have been introduced to China. In the following a long period of time, PE-Xa pipes because excellent heat resistance, low price to get the majority of construction companies love to warm, had become the "hegemony" of floor heating pipe market. After a single PE-RT tube into the Chinese market, under the combined effect of various factors, and its development in the Chinese market is very fast warm Meng. Currently PE-RT pipe production and sales in the market have been more than the PE-Xa pipes. This election of 15 companies reporting data, the performance was very obvious. Statistics show that Wang Yue, Kinder, Liansu, Wei Xing, Taurus, army star, gold wave, finite George, love 康保利, Japan and Thailand, said Cheng, Henan RAJ Industry Co., Ltd and Longkou Nanshan Plastic Building Materials Companies 13 to warm the pipe business in 2012 purchased a total of about 180,000 tons of raw materials to warm the pipe. These materials are 35% from LG Chemical, about 31% came from SK Chemical. Statistics show that all the material for the 13 reporting companies purchased in 2012, PE-RT pipe material is about 139,200 tons, accounting for about 77% of these 13 candidate enterprises in 2012 the total procurement of raw materials. According to statistics, the above-mentioned 13 enterprises purchase of PE-RT pipes about 40% of the raw material from SK Chemical, about 30% comes from LG Chem. Statistics show that Liansu, Wei Xing, gold surges and Road-procurement PE-RT pipes more than 59 percent of raw materials from SK Chemical. And Wang Yue, Japan and Thailand, Icahn, Nanshan, military stars and Wingo these six companies purchased PE-RT pipes more than 63 percent of raw materials from LG Chem. In addition, Icahn, George and Kinder procurement PE-RT pipes are also part of the raw material from Dow Chemical (China) Limited. Data show that above 13 run businesses in 2012 purchased a total of about 22,800 tons of raw materials PE-Xa pipes, covering around 13% of heating pipe total procurement of raw materials. In the production of PE-Xa pipes Wang Yue, Raj, said Cheng, Thai and Japanese military satellite that five companies, said Cheng PE-Xa pipes in 2012 all chose the PE-Xa pipe material Honam Petrochemical, the Swiss Chak purchasing raw materials PE-Xa pipes are from Honam Petrochemical and Samsung Star Army, Japan Taihe Wang Yue three companies in 2012 purchased PE-Xa pipe all the raw materials from LG Chem. Analysis of data from the above that, run businesses in 2012 purchased raw material PE-RT pipes PE-Xa is six times more than the tube. In this case the production of the type of candidate to warm tube can also be reflected. In the 13 companies, not to produce PE-Xa pipe with Kinder, George, Liansu, Icahn, Wei Xing, Jin Chao, Nanshan and Taurus 8, which only produces PE-RT to warm the pipe with Kinder Nanshan two companies. (Due to PB pipes and PE-Xb pipes to warm the pipe market also occupy a certain market share. Therefore, in addition to Kinder and Nanshan two companies, and the remaining six companies involved in the PB pipe or PE-Xb pipe business.) In PE-Xa pipe production RAJ, said Cheng, Star Army, Japan Taihe Wang Yue This five companies, PE-Xa pipes to warm the pipe business accounted for more than 60% of the total business, Dao, Cheng and RAJ only two, military satellite, to warm the pipe business, Thailand, Wang Yue of the PE-Xa pipe accounting for about between 17% to 47%. Floor heating floor heating construction process of the construction process: find a floor level flat line - the grass-roots clean up the floor, leveling - laying insulation (polystyrene board, etc.) - plus reflective film, PE-RT pipe laying - adjustment spacing, fixed pipe - installed water separator - and water separator system closed - Corner insulation - pressure test - pouring fine aggregate concrete pad - pressure test to check again - after passing the test do the ground surface (Note: Normally not winter construction) construction procedures and technical requirements: 1) to find a floor level flat line: Clean floor grassroots level, leveling. Uneven tolerances within 8mm. 2) waterproof layer arrangement: Ground damp or first floor of buildings should be laid insulation waterproof material. 3) the laying of the reflective layer: PE-RT pipes should be laid on the insulation board affixed aluminum foil, aluminum foil side up. Requirements ground level laying insulation board, insulation tape firmly affixed seams. 4) the laying of PE-RT pipe, adjust the spacing, fixed pipe: insulation board, PE-RT pipes from far to near by ring laying pipelines using special plastic card (or template) is fixed insulation board, plastic staples spaced not more than 500mm, the corner is not more than 250mm. 5) Install the sub-catchment, sub-catchment system and closed: wall installation at the manifold handle to advance plastering, sub-catchment fixed in the wall or a dedicated box, from the ground should be greater than 350mm, and away from the heating furnace close and easy communication with the room hall location. 6) corner insulation: with special insulation strips were corner corner insulation construction. 7) pressure test: the test pressure shall be 1.5 times the working pressure of not less than 0.6MPa. Under test pressure regulator 1 hour, the pressure drop should not exceed 0.05MPa. 8) pouring fine concrete pad: After passing the test pressure should be pouring concrete cushion season stone ground beans, artificial TROWELING dense, then the pipeline should maintain not less than 0.4MPa pressure. 9) pressure test to check again. When the floor heating system should pay attention to what? Author: Date: 2011-06-15 17:10:40 Views: 3722 low temperature radiant floor heating system is based on low-temperature hot water as heat medium, buried in the ground through pipes to warm the floor heating, uniform radiation to the interior heat, hot microclimate of room to adjust the energy-saving heating system, a comfortable heat balanced, easy energy saving, maintenance, management, etc., is a highly desirable way of heating. Use the following method for your reference: First, if the ground is not decoration, concrete floor may be a slight cracking is normal, it will not have any impact on your future renovation ground. To avoid accidentally destroyed water customers renovation, so forbidden to enter on the ground or nail cutting nail, drill nails, concrete nails and other hard metal material, if not playing is not, by reference to guide the construction drawings in the construction side operating. Second, if they inadvertently cause damage to underground piping system leaks, the user can first valve on each water trap closed, and promptly ask the property management department. Third, the trap to use: 1, manifold can be divided into channel control of each room (or area) of the heating temperature, such as: any way to turn the diverter valve on the core half closed, this water heating room the temperature will decrease. 2, the manual vent valve manifold: Users can own the gas pipeline in order to ensure that the entire inside of the exhaust pipe in the heating and hot water circulation normal. 3, the front end of the drain valve manifold: the user can at the end of each year during the heating season or heating clogging the drain valve on the bottom of the sewage network installed after removing the cleaning, in order to ensure the smooth flow of the pipeline clean to prevent clogging. 4, at the bare manifold pipe should avoid contact with organic solvents, such as: alcohol, gasoline, paint, asphalt. Fourth, the consumer who wants to lay the floor, you should try to choose a warm floor or a special bonding formula, spell plug type flooring and artificial flooring. Fifth, if the interior is not heating in winter, it should notify the property of the inner coil water discharge, and dry with a pump, close the supply and return valve to prevent the cracking pipes. On the device to warm to warm mixing water is mixing water means to solve water temperatures warm water sources preferred embodiment is the use of heat to warm the cold after the hot water is mixed with the return water to provide adequate heating water temperature, has a simple, convenient, comfortable temperature stability of outstanding advantages, has been widely used. We usually say to warm "low temperature hot water floor radiant heating system" for short, with traditional radiator heating mode compared with the comfort, energy saving, health characteristics. However, warm water temperature have more stringent requirements: the use of floor tile floor system, hot water maximum temperature 60 ℃; composite wood floor floor heating systems generally require water temperature below 45 ℃; solid wood flooring requires water temperature no higher than 35 ℃. At present, China central heating or district heating systems are mostly designed for radiator heating customers, the general supply to the users of the water temperature at 80 ℃ -90 ℃, much higher than required to warm the water temperature, and therefore can not be directly used to warm. This makes a lot of central heating to warm the user look disappointed, but warm suppliers had to shut out a large number of users. Means for mixing water central heating to warm the user, its main role is to improve the safety and comfort of use of warm, energy-saving effect is secondary; even with energy savings, but also by controlling the temperature does not exceed the required temperature achieved, mixing water temperature mixing device itself is only a means, is a small difference in the temperature of hot water flow into a low temperature difference between the large flow of circulating water system itself does not have any role in energy conservation. After using the mixing water device that can give central heating provide suitable cryogenic large flow to warm circulating water meet warm for the safety and comfort requirements, on the basis from the warm regulations found: "floor radiant heating technology point of order" (JGJ142-2004) in the main water temperature for the following provisions: Article 3.1.1: for low temperature hot water floor radiant heating system, return water temperature should be calculated and determined. Civil water temperature should adopt 35-50 ℃, should not exceed 60 ℃, supply, return water temperature should be less than or equal to 10 ℃. Maximum water temperature should not exceed 60 ℃ warm affecting safe use of the most important parameters, in order to ensure the life of warm, should be strictly adhered to; for floor heating pipe, temperature has a very large impact on their life and aging properties, such as PE-RT Tube life of up to below 60 ℃ 50 years, 70 ℃ reduced to 10 years, 80 ℃ only two years, 90 ℃ only one year. Life curve above the data from the relevant pipe manufacturer provided can be seen, therefore control the temperature has a very important meaning for a long time to warm safety. Water temperature range 35-50 ℃ specific basis for determining the average room temperature and ground temperature, mainly to improve in terms of comfort of use; supply and return water temperature less than 10 ℃ is to keep the ground temperature uniformity and high energy efficiency, with a energy conservation, improve comfort and avoid excessive temperature thermal stress to consider the formation of ground material aspects; according to our experience, many users Central Plains water temperature reaches about 40 ℃ can achieve good results, the water temperature is too high but lead warm temperature is too high, indoor dry and other issues. Article 3.8.4 low temperature hot water floor radiant heating system should be set to adjust the heating temperature control means in the heat. This provision clearly central heating and other users should be used to warm the temperature to warm mixing water devices, conditioning, pay attention, here referred to as "heating temperature control device" instead of "heat flow regulating device", so use flow regulator valve control is not suitable way. The above provisions is a key factor in warm comfort guaranteed to warm you need to open some windows, mainly ground temperature is not well controlled, and the control surface temperature is the best way to regulate the water temperature, not regulate the water flow. In summary, for central heating floor heating systems and radiators and floor heating, shared systems, installation troubled waters means it is very necessary. Then use the gas boiler for users, is not no need to install troubled waters means it? The answer is no! Although the boiler heating water temperature can be adjusted to warm temperature, but its design temperature and flow rate is usually carried out in accordance with radiator heating used directly to warm, it will cause the water temperature is set lower boiler output power decreases, the heat exchanger surface knot Lu affect the life, circulating water flow enough and so on. For example: 24KW boiler, the water temperature 85 ℃ power is calculated directly used to warm, the water temperature was adjusted to 60 ℃, its actual operating power is reduced to 16-18KW, precisely for this reason, cause the boiler and heating system of the "big horse car" phenomenon. After installing the device and mixing water, a good solution to this problem, simply means "small boiler can bring warm earth," so not to increase the burden on the boiler, but the configuration of the entire heating system is more balanced, more stable . Warm construction of pipeline damage treatment program in warm construction, the traditional process is a reflection film carboplatin nail method, this construction method to warm the pipe lack of effective protection measures, and second, and to warm the construction often and houses in the overall renovation together test performed, so that to warm the pipe laying is completed, to warm the pipe to withstand construction workers to and fro stampede and various tools, too easy to cause wear or even damage the pipe. PE-RT pipe can be hot-melt, so for PE-RT pipes for hot-melt approach can be used to deal with leaks and damage. However, this approach operate more trouble, the operator of the hot-melt technology also has a high demand, should be carried out after the completion of the hot melt pressure test before backfilling operation after passing; now have a more convenient, faster, and more safe disposal method - quick connector! qq.jpg quick connector for quick connection PE-RT pipes, plastic composite pipe, PE-X pipes, pipe and other piping oxygen barrier. Since the internal use of the clamp ring and two O-ring structure allows a permanent leak-proof! No rust: All uses imported high-performance resin; non-disclosure: National Chemical Building Materials Testing Center; do not fall off: both ends of the tension can withstand 180KG; construction is simple: do not need any tools, by hand can be fixed. Usage: 1, first cut smooth tube port, do not have the glitch and ramps; 2, with the reamer will scratch the incision Park; 3, the tube inserted into the joint by hand; (! Do not need any other tools) 4, small After the instant the shutter was forced open, and issued a "bang" sound indicates that the connection is successful, through the transparent body with your eyes can also determine the status of construction.
