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: 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!

Q: Air conditioning ventilation when the sound is a big reason: According to my specific circumstances, in the following seven major hazards include the division, sub-project focus on control

Q: Gree air conditioning 50 heating and cooling mechanism heat when the host cooling network is how the matter: Can be small, according to your roof to do what material.

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 machine work when the sound is too much reason: Many of the good quality of the model, of course, bear some of the larger. Common scaffolding brackets are U-type care, "construction fastener steel scaffold safety technical regulations" (JGJ130-2011) provides "adjustable support bearing capacity design value should not be less than 40kN, support plate thickness should not be less than 5mm ", the general calculation using 30kN. Not to say how fast buckle steel scaffold can bear the load, but according to how much load to calculate how scaffolding erection. Need to be calculated. In the "construction of fasteners steel scaffold safety technical specifications" provides instructions. Double fastener (anti - skid) bearing capacity design value 3.2KN. Right angle fastener, rotary fastener (anti-skid) bearing capacity design value 8KN.

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: The installation method of ordinary air conditioner. The more detailed the better. Please thank you all: The basic operation of the same, but the different requirements of different professional, or to determine the direction of good, and then hands.

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: HVAC Heating: What are the main components of the air distribution system?: Geothermal construction, the heating pipe spacing can not be less than 100mm, the construction can not be achieved, big brother!
