FAQ:

Insulated Flexible Ductings Biggest Manufacturer in China

Q:I added the space 18 degrees opened for 5 hours or not cold, we all know how is it? More: 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:Such as the problem, and now air-conditioning technology is mature, the market a lot of air conditioning are cold and warm, and I would like to be able to put my home that the end of the century loaded Mitsubishi air conditioning (split single cold) into a cold Before the conversion of ordinary TV to the remote control, that air conditioning can be modified? How much does it cost? Where is this technology? More: External wall insulation should pay attention to what the details?

Q:In the design, the building structure and the hydropower are generally designed by the Architectural Design Institute. The air conditioning ventilation is based on the design of the room. Or first air conditioning ventilation? More: Aluminum alloy metal shell better than the plastic shell; we all know that most of the market is now charging the lithium battery, lithium battery is the only drawback is the possibility of a long time with the explosion, so the use of aluminum Alloy shell, much better than steel; polymer battery is good, but the price is expensive,

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:External wall insulation method of operation There are several combinations of materials: Seeking the existing building construction specifications Daquan! The The @

Q:Gree air conditioning 50 heating and cooling mechanism heat when the host cooling network is how the matter: Not the ,,, mobile air conditioning inside the compressor, the winter heating also need the compressor, but also a ventilation pipe, charged heating Well?

Q:Ventilation is very good, why still have to install fresh air system: Also known as foam board, EPS board, is containing volatile liquid blowing agent of the polystyrene beads can be preheated by heating, heated in the mold and the formation of white objects

Q:If I feel the room cool off, one hour hot and open an hour this will be more expensive? More: Common scaffold brace is the U-type care, "construction of fasteners steel scaffolding safety technical regulations" (JGJ Gong Gong Duo Ji-tao pan Revenge two 130-2011) provides "adjustable support bearing capacity design value is not Should be less than 40kN, the support plate thickness should not be less than 5mm ", the general calculation using 30kN.

Q:What is the whole heat exchange fresh air ventilator?: Depends on the main control panel is not cold and warm, single cold common motherboard. Only a generic motherboard can be changed. In the single cold air-conditioning on the outdoor machine to install the appropriate specifications of the four-way valve, adjust the amount of refrigerant to the appropriate level can be.

Q:Air to water heater host and air conditioning host is not the same: You can try asphalt! Is the kind of paving the way! Very useful!
