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.
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
Decoration refers to the home improvement part, housing construction is the content of the building
Air to water heater host and air conditioning host is not the same
Issued a test report, Detection can be used to pass, failed to use!
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
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?
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
External wall insulation method of operation There are several combinations of materials
Seeking the existing building construction specifications Daquan! The The @
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
