Q:External wall insulation method of operation There are several combinations of materials
30-150 per square meter has, mainly to see the material, thickness and so on
Q:Space blowing wind is not cold how is it?
Common points are all sandwich panels, with a hard protective layer, the difference is the middle of the different materials, such as polystyrene board, polyurethane board. Polystyrene board which is the most common, because the price is cheap, easy to use so the use of more, but if the temperature is more than the requirements of the chicken inertia glycosylation moxibustion slim faint words, polystyrene board is not satisfied , So there is a polyurethane sandwich panels, polyurethane thermal conductivity of less than 0.. in the existing insulation materials, large quantities of processing, be the best. But because of its process is more complex, and the cost is relatively high, so with less, the common combination of cold storage and the like, I believe that with the economic and technological development, polyurethane sandwich board market share will be more and more High
Q:Air conditioning ventilation when the sound is a big reason
No matter, it is best to cut the distance between the material and the roof, like an arbor. Otherwise it is not foam board with it
Q:The installation method of ordinary air conditioner. The more detailed the better. Please thank you all
2.1.23 step distance liftheight the distance between the upper and lower horizontal axis of the axis of each other. 2.1.24 pole vertical (cross) distance longitudinal spacingofuprighttube Scaffolding vertical distance between adjacent rods. 2.1.25 Vertical distance transversespacingofuprighttube Scaffolding Horizontal distance between adjacent vertical rods, single row scaffolding for the outside pole axis to the wall distance.
Q:HVAC Heating: What are the main components of the air distribution system?
(HS Code) Yes, the tax rebate is 13% (April . 2009 latest data). Floor of the board of the tax number is, the tax rebate is 9% (June . 2009 the latest data), floor board is the inspection of goods, exports need to be checked. There is nothing to understand where to add me MSN: kfwdz@hotmail.com
Q:Air conditioning machine work when the sound is too much reason
This is based on the density of benzene board decision, not what you said, know it buddy.
Q:Air to water heater host and air conditioning host is not the same
This test with a small sample length 127mm, width 12.7mm, the maximum thickness of 3.2mm. In the absence of ventilation test chamber. The top of the specimen (6.4 mm place) is clamped with a clamp on the bracket and the longitudinal axis of the specimen is kept vertical. The lower end of the specimen is 9.5mm from the lamp tip and 305mm from the dry absorbent cotton surface. Bring the Bunsen burner and adjust it to produce a blue flame with a height of 19mm. Place the Bunsen Lights flame at the bottom of the sample for 10s, then remove the flame (at least 152mm away from the specimen) and write down the sample. Burning time. If the flame of the sample within 30s after removal of the flame is extinguished, the original lamp must be moved under the specimen again, re-ignite the sample for 10s, and then remove the Bunsen burner again and note the flame burning And flames burning the burning time. If the sample droplets drip, let it fall into the sample under the 305mm cotton, to see whether it ignited cotton. If the absorbent cotton is on fire, the rating should be taken into account. Specific grading indicators are as follows. Test Item 94V-094V-194V-21 Ten-time ignition Total flame burning time Maximum value (S) Individual flame burning time Maximum value (s) Flameless burning time (s) Yes Flame drop No No Allow only short time Burning general UL yellow card on the thickness of the test strip is divided into: 1/8 inch, 1/16 inch, 1/32 inch thickness, that is, 3.2mm, 1.6mm, 0.8mm three grades test.
Q:The United States direct mail dyson hp01 Dyson air purification cooling machine triple in the country to warranty it
Embedded stove, such as the use of rubber tube connection, then the rubber tube in the platen, often subject to heat radiation easily aging; and aging, falling more difficult to find, so many local poisoning and other vicious accidents
Q:Do 3cm thick wall insulation how much kilogram of slurry and how many kilograms of polystyrene particles
From the outside: ① rigid waterproof casing is only composed of steel casing and wing ring, simple structure; ② flexible waterproof casing mainly by: flange casing, seals, flange pressure plate, wing ring, bolts, nuts Composition, complex structure From the waterproof performance up to choose: ① rigid waterproof casing is outside the wing (ring made of steel ring on the steel pipe), installed in the wall (mostly concrete wall), for the general pipe wall, ; ② flexible waterproof casing in addition to the external wing ring, the internal file ring and the like, the flange wire, there are sets of sales, but also their own processing, for the need for shock absorption pipeline, such as and pump connected When the pipe is through the wall In other words, if the wall on both sides of the waterproof performance, it is necessary to use flexible waterproof casing; if only to consider the pipe through the wall, without considering the wall, the wall on both sides of the waterproof performance and displacement of the pipeline deformation You can use rigid waterproof casing
Q:Single cold air conditioning function can not change the cold and warm?
So good, then you recommend more. Give an address. You are not layman, too modest.
