Q:What is the whole heat exchange fresh air ventilator?
(GJG130 - Fan Jutang Duanjie Daojie Juejiao 2001) will be replaced by (GJG130-2011) is expected to begin the implementation of the construction of this year, the construction of fastener steel scaffolding safety technical specifications (GJG130), the construction of fastening steel pipe scaffolding safety technical specifications (GJG130- -2011)
Q:Gree air conditioning 50 heating and cooling mechanism heat when the host cooling network is how the matter
Extruded board of course, can generally use this to do, indoor and outdoor to do almost, most of the outside is done because of saving space inside the room. Recommended: do indoors, because I was doing the external walls, the insulation often do, the wall is not very good for the first time, because you do before the insulation wall itself is the weight of the valve valve closure of the bone shop stall wipes , Benzene board sticky benzene board is not very strong, live well for a few years, bad two or three years there will be signs of shedding, looking twice thinking.
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:Ventilation is very good, why still have to install fresh air system
You are a single raft toilet wipes Pie Tanzhuang open card would like to confirm what? Contract notarization or. The The If it is contract notarized, generally notary value of 0.25% -0.3%
Q:Air conditioning ventilation when the sound is a big reason
Buried plastic pipe under external load, the diameter of the vertical diameter deformation rate should be less than the allowable diameter of the pipe deformation rate The diameter of the allowable diameter of the pipe shall not be greater than 5% The diameter deformation rate of the pipe and the allowable diameter deformation rate are calculated as follows: ε ΔD / D0 × 100% [ε] ε0 / K where: εΔD pipe in the combined load (Mm) [ε] Permissible diameter Deformation rate ε0 Elastic diameter Deformation rate (%) of pipe, by the flattening of the diameter of the pipe diameter (mm) The test determines the K safety factor, generally desirable 15
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:Public building design, the building structure and water is generally designed by the Architectural Design Institute, air conditioning and ventilation is based on the design of the interior? Or first air conditioning ventilation?
Polystyrene should not be polycyclic aromatic. Polycyclic aromatic groups generally refer to aromatic groups when multiple benzene rings are used. Not all of the hydrocarbon chemical products are carcinogenic, and our bodies are producing hydrocarbon compounds all the time. Polystyrene carcinogenicity is small. General benzene ring on the more substituents, the toxicity is relatively small, such as toluene is less than the toxicity of benzene. Of course, there are many compounds with benzene ring, so there are a lot of scholars to study with our body creatures do not meet the quality of raw materials to do the polymer, such as lactic acid production of polylactic acid, but the current Can be put into use much.
Q:Do 3cm thick wall insulation how much kilogram of slurry and how many kilograms of polystyrene particles
Of course, is heating electricity. Heating has auxiliary electric heating, so electricity and electricity. Frequently open the fee, the air compressor is not good. 2 machine cooling power is 1700 watts, 1 hour is 1.7 degrees electricity. Heating with auxiliary electric heating power of 1500 watts, 1 hour is 3.2 degrees electricity.
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.
