Q: If I feel the room cool off, one hour hot and open an hour this will be more expensive? More: No, polycyclic aromatic should be anthraquinone This is certainly not all of the hydrocarbons are carcinogenic

Q: 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!

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: US direct mail dysonhp01 Dyson air purification cooling machine triple in the country to warranty it: Embedded stove, such as the use of rubber tube connection, then the rubber tube in the platen, often subject to heat radiation easily aging; and aging, falling more difficult to find, so many local poisoning and other vicious accidents

Q: Air conditioning machine work when the sound is too much reason: Color steel plate, refers to the color coated steel plate, color coated steel plate is a kind of organic coating with steel plate

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

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: 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: Polystyrene should not be polycyclic aromatic. Polycyclic aromatic groups generally refer to aromatic groups when multiple benzene rings are used. Not all of the hydrocarbon chemical products are carcinogenic, and our bodies are producing hydrocarbon compounds all the time. Polystyrene carcinogenicity is small. General benzene ring on the more substituents, the toxicity is relatively small, such as toluene is less than the toxicity of benzene. Of course, there are many compounds with benzene ring, so there are a lot of scholars to study with our body creatures do not meet the quality of raw materials to do the polymer, such as lactic acid production of polylactic acid, but the current Can be put into use much.

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!
