Floor heating has a few problems that need attention, you know? With the arrival of cold weather in winter, many people are going to choose to install floor heating, have a warm room in their home environment. Heating a system, covers all aspects of the problem.
1. Select the heating pipe problems: select will directly affect the life of the floor heating system heating pipes, floor heating system is a system of long-term covert use, choose what kind of heating pipe directly affects the life of the whole system. When selecting a heating pipe can select imported pipe or joint-venture companies, no province during an initial installation cost, select the pipe too cheap at a later stage, maintenance costs or even in early times, and a construction boom. So choose good quality pipes, is the high cost is worth it.
2. Select water-divide problem: water-divide is the main material of the floor heating system, quality, directly related to the operation of the whole system, and may not match the corresponding temperature, causing budget overruns. In this regard, importing diversity has great advantages in quality and uneven domestic products, and applied for a short time, the quality varies greatly, so choose carefully, suggested the use of products from well-known manufacturers.
3. install floor heating engineering problem: accurate should be strictly in accordance with construction drawing design, due to warm is a system, when installed, must be good and home improvement, and must not be installed on the warm floor random construction work, has the potential to cause damage to the heater. And cannot be opened without permission to warm the device, if it will affect the construction, you must get in touch with installing floor heating supplier, in time.
4. There is no need to install temperature-controlled Central: some type of heating area is big, generally recommend installing temperature-controlled Central, so that each can be individually set the heating temperature of the room, or you can set the temperature of the room to a minimum, keep running. By temperature-controlled central control, significantly saving energy profligacy; and easier centralized management control.
Different from those used to electronics and solar cells, monocrystalline silicon, is also different from amorphous silicon thin-film devices and solar cells, polysilicon is made up of tiny silicon materials. Major polysilicon producer Hemlock Semiconductor, OCI, WACKER (Wacker Chemie), GCL-poly energy, and REC, LDK Solar, MEMC, and some smaller producers.
Polysilicon industry is developing rapidly, and levels above 1000t polysilicon production plant were built. However, polysilicon production process, hydrogen, chlorine, trichlorosilane and silicon and other harmful substances, and there are fire, explosion, poisoning, suffocation, electric shock injuries and many other risk factors.
Harmful substances produced in the polysilicon production process of chlorine gas, hydrogen, Silicon, hydrogen chloride, trichlorosilane, main risk characteristics are:
1. hydrogen gas: mix can form explosive mixtures with air, heat or open flame or explosion. Gas is lighter than air, when indoors use and storage, leakage increased stranded roof difficult to discharge, when Mars will cause an explosion. Halogens such as fluorine, chlorine, bromine and hydrogen will react violently.
2. oxygen, combustible materials, combustible matter combustion and explosion of one of the essential elements and oxidation of most active substances. And combustible (such as acetylene and methane) forms explosive mixtures.
3. chlorine: a pungent odor and can be generated with a number of chemical explosions or explosive material. Almost all metallic and non-metallic corrosion. Are highly toxic. Is a strong irritant gases.
4. hydrogen chloride: anhydrous hydrogen chloride is non corrosive, but when in contact with water, are corrosive. Can react with reactive metal powders, releasing hydrogen gas. Cyanide can produce highly toxic hydrogen cyanide gas.
5. three hydrogen Silicon chlorine: open flame burning strongly. Subject to high thermal decomposition may produce toxic chlorine gas. Reacts with oxidants, are a fire hazard. Very volatile and fumes in the air, in contact with water or water vapour can generate heat and toxic corrosive smoke. Combustion (decomposition) products: hydrogen chloride, silica.
6. Silicon tetrachloride: heating or hot water liberation, release toxic corrosive smoke.
7. hydrofluoric acid: corrosive, very strong. H vesicant immediately burned. Can react with bare metal and releases hydrogen with air to form an explosive mixture.
8. a nitric acid: strong oxidizing. And combustible (such as benzene) and organic matter (such as sugar, cellulose) exposure will react violently, even cause fire. With alkali metals react violently. Has strong corrosion resistance.
9. the nitrogen: in case of high fever, increased pressure within the container. Cracking and danger of explosion.
10. hydrogen fluoride: highly corrosive. In case of high fever, increased pressure within the container, is in danger of cracking and exploding.
11. sodium hydroxide solution: this product is non-combustible, with strong strong corrosive, irritant can cause the human body burns.
Second, electric shock, other risk factors such as mechanical damage
Fire, explosion, poisoning is polysilicon projects in major danger and harmful factors in production, in addition, there is electric shock, mechanical damage, corrosion, dust and other hazardous and harmful factors. Are:
1. preparation of hydrogen: electrolyzer, hydrogen, and oxygen tanks, fire and explosion, electric shock and mechanical damage.
2. hydrogen chloride synthesis: synthesis furnace of hydrogen chloride, chlorine and hydrogen gas buffer tanks, fire and explosion, poisoning, electrocution.
3. the three Silicon-hydrogen chloride synthesis: three Silicon-hydrogen chloride synthesis furnace, synthesis gas scrubbers, feeding machine, fire and explosion, electric shock, poisoning, corrosion, mechanical damage and dust.
4. the synthesis gas separation: mixed gas scrubber, hydrogen chloride absorption tower, Tower, the mixed gas compressor hydrogen chloride resolved, fire and explosion, electric shock, poisoning, corrosion, mechanical damage.
5. separation of chlorosilanes: distillation, reboiler, condenser air, fire and explosion, electric shock, poisoning, corrosion, mechanical damage.
6. the three hydrogen Silicon chlorine reduction: three hydrogen Silicon chlorine carburetor, reduction furnace, reduction furnace cooling water circulation pumps, fire and explosion, electric shock, poisoning, corrosion, mechanical damage.
7. restore gas separation: mixed gas scrubber, gas compressors, hydrogen chloride absorption towers, fire and explosion, electric shock, poisoning, corrosion, mechanical damage.
8. hydrogen-Silicon tetrachloride: Silicon tetrachloride carburetor, hydrogen furnace, fire and explosion, electric shock, poisoning, corrosion, mechanical damage.
Based on the above analysis, it is the main potential risks of fire and explosion, chemical poisoning, harmful factors in terms of technology, equipment, facilities and protection problems and defects, is very likely to occur, it should be for reasons that may occur and take preventive measures to actively exclude.
Primary prevention measures are: automatic control system for production use, and improve the standard of control; in chlorine, hydrogen chloride, trichlorosilane Silicon Silicon chloride, hydrochloric acid, easy to leak part of fresh air and sets flammable and toxic gas detection and alarm system; personnel issued qualified for the job for antivirus, dust-proof and burns and other protective equipment to avoid risks of polysilicon.
Warm radiator pros and cons about starting from the first House until now, is constantly learning, a little dizzy, the problem with this is the benevolent.
Just finished decoration and immediately renovated a House, through practice, comparison, I still want to try change: simple or primitive style last time and, more recently, of simple pastoral grasses begin to grow, my husband says I’m too fickle, and alas! Say say it right, maybe a couple of days and changed my mind about it?
Floor heating is much better than radiator. In fact, heating technology and materials is very mature and has decades of history in China, just about enough to know it will have to be worried. Floor heating does not occupy the indoor space relative to the radiator, more comfortable than radiator heating, heating customer will save money. As long as the heating of underground pipelines during construction is impossible to protect late may cause a problem, much more security than the radiator, the radiator’s interface is very easy to leak, and relative to the life of the radiator to warm to much shorter. To warm the fault rate is much smaller, and maintenance is simple.
So I think now is sure to open your eyes and select a trustworthy shop, doing well to warm! Maybe ten years after, renovation, demolition, think are terrible, renovation is tiring!27455
Air conditioning in some counters, sales staff said the air conditioning in a level 4 grade 1 efficiency energy efficiency is equivalent to other brands, in fact here, the salesperson is constant-frequency air conditioning inverter air conditioner efficiency ratings and mixed with the energy efficiency levels of contrast, he means a level 4 of variable frequency air conditioning energy efficiency equivalent to level 1 of another fixed-frequency air conditioning energy efficiency.
In interviews, reporters also found a citizen is the selection of air conditioning was a little confused and asked: “energy efficiency standards for national unity, don’t you? why are 4 levels of energy efficiency, the air conditioning energy efficiency ratio is 3.4, but that air conditioning is just 2.8? what about this air conditioner can save much electricity?” At least once a month, 60~70du. “The sales staff said, pretty sure. “Can save so much? ‘ how was this data out?” ” Calculation method is complex and involves a lot of expertise, I don’t know specifically, but buying it must deal, put up energy efficiency labeling of a simulated? ” Ultimately, the customer is befuddled and left.
In the course of visits to, the reporter noted, some outside sales personnel, in addition to greater efficiency than the vague, is also alleged to have misled consumers. In another air conditioning counters, sales staff even told customers, just labeled as “China energy efficiency labeling” air conditioners are energy-saving products. In fact, air conditioner “energy label” consists of 1, 2, 3, 4, 55, only energy efficiency for level 1, level 2, products can be called energy-efficient products, like 5 levels represent energy-intensive products, market access indicators and, therefore, not “energy label” equate the and saving energy.
B simple formulas to help you count the air conditioning energy saving accounts
In fact, to count the air conditioning energy saving accounts, must first figure out air conditioner “energy efficiency ratio”, because it is a measure of an air conditioner is energy efficient or low energy-efficiency standards.
The so-called “energy efficiency ratio” is the ratio of air conditioning refrigeration and cooling power, in other words, is 1-kilowatt how many kilowatt of electricity generated by an air conditioner with a cooling capacity, for example a 2P air conditioner cooling capacity is 5000W, cooling power is 1785W, so its energy efficiency ratio is 5000/1785=2.8, EER, the greater, shows air conditioning energy efficiency rating, the higher energy the better.
At present, the State aiming at constant speed inverter air conditioner and air conditioning, and enactments of two corresponding to the energy efficiency standards, among them, the constant-speed air conditioner 1~5-level energy efficiency ratio was 3.4, 3.2, 3.0, 2.8, 2.6 and 5.2 per cent of variable frequency air conditioning, 4.5, 3.9, 3.4, 3.0.
Then, on a daily basis, high level energy efficiency ratio EER air conditioning is better than low level air conditioning how much electricity it? gree electric appliances sales co marketing Dragon Minister told reporters that settled this account, it’s really quite simple, or as a cooling capacity up to 5000W 2P air conditioning, for example:
Grade 1 efficiency of the electricity consumption of 5000W/3.4=1471W, namely, power consumption per hour 1.471
2 energy-efficient electricity consumption of 5000W/3.2=1563W, 1.563 per hour electricity
At current electricity charges 0.62 Yuan/degree calculation, if a family uses 4 months in a year (about 120 days), power on 8 hours a day, the grade 1 efficiency ratio 2-level energy efficiency can save a year for electricity: (1.563-1.471) x8x120x0.62=54.76 ().
Summer, the home of the meter just like mounting the motor, go fast, coupled with a rise in electricity prices, and energy conservation awareness is becoming more and more strong, air conditioning in some air conditioning consumers to figure out how to make the family’s electricity-saving, studying air conditioning not only open to a few degrees of electricity. Constant temperature air conditioning experts in Hunan told the secret of your air conditioning costs, hopes to use air conditioning at a later time more wisely.
The heat of the summer, usually turn on the air conditioning back home, transferred to the extreme low temperature, is also sweating on the outside, entered the House as it as if we were into the Icehouse, cool is cool, but this is likely to cause the common cold, but electricity has many. Watch air conditioning remote control, refrigeration can be up to 16 degrees Celsius, what should the thermostat to how many degrees do better? Tell you that air conditioning set at 26 degree Celsius is best and why?
This is because the impact on human health of comfort in addition to lighting, air conditioning, color perception, as well as temperature and humidity. Statistics showed that the best human comfort when the temperature is between 24~28℃. Another point, set the air conditioner at 26 ° c has an economic benefit. Taking the city of Changsha as an example, if an air conditioner temperature increases of 1.5 HP split air conditioner 1 c, 0.4 kWh of electricity savings from run for 6 hours a day, calculated according to 4 months in the summer, you can power-saving 48 degrees, is around 70, in fact, value is much greater than this value.
To sum up, household air conditioning up to 26 ° c is the most comfortable, most without electricity!
