FAQ

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

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,

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

US direct mail dysonhp01 Dyson air purification cooling machine triple in the country to warranty it

Among them, the extruded polystyrene gypsum composite board is based on paper gypsum substrate, the use of adhesive and extruded polystyrene board through the factory processing compound

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

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

If I feel the room cool off, one hour hot and open an hour this will be more expensive? More

But after all, is the master you want to Zhuo good jade is certainly a lot of difficulties, whether it is Longfeng Pei or other subject matter need a lot of effort in addition to the need for technical research also need to continue to learn theoretical knowledge, especially

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.
