Q:I added the space 18 degrees opened for 5 hours or not cold, we all know how is it? More

The general level of more than 12 layers when you need to use.

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:

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

So good, then you recommend more. Give an address. You are not layman, too modest.

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: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

30-150 per square meter has, mainly to see the material, thickness and so on

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: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

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

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.
