FAQ

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

External wall insulation should pay attention to what the details?

What is the whole heat exchange fresh air ventilator?

Second, the new insulation decorative board is integrated through the production line, set insulation, waterproof, finishes and other functions in one, is to meet the current housing construction energy needs, improve the industrial and civil building exterior wall insulation level of the preferred material, but also on the existing Building energy-saving transformation of the preferred materials

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

Normal heat absorption is also due to poor ventilation (dirty) and air humidity so icing

Air to water heater host and air conditioning host is not the same

This test with a small sample length 127mm, width 12.7mm, the maximum thickness of 3.2mm. In the absence of ventilation test chamber. The top of the specimen (6.4 mm place) is clamped with a clamp on the bracket and the longitudinal axis of the specimen is kept vertical. The lower end of the specimen is 9.5mm from the lamp tip and 305mm from the dry absorbent cotton surface. Bring the Bunsen burner and adjust it to produce a blue flame with a height of 19mm. Place the Bunsen Lights flame at the bottom of the sample for 10s, then remove the flame (at least 152mm away from the specimen) and write down the sample. Burning time. If the flame of the sample within 30s after removal of the flame is extinguished, the original lamp must be moved under the specimen again, re-ignite the sample for 10s, and then remove the Bunsen burner again and note the flame burning And flames burning the burning time. If the sample droplets drip, let it fall into the sample under the 305mm cotton, to see whether it ignited cotton. If the absorbent cotton is on fire, the rating should be taken into account. Specific grading indicators are as follows. Test Item 94V-094V-194V-21 Ten-time ignition Total flame burning time Maximum value (S) Individual flame burning time Maximum value (s) Flameless burning time (s) Yes Flame drop No No Allow only short time Burning general UL yellow card on the thickness of the test strip is divided into: 1/8 inch, 1/16 inch, 1/32 inch thickness, that is, 3.2mm, 1.6mm, 0.8mm three grades test.

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.

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

After learning that feel boring, to diverted it, brush point repair it. Architectural design institute will need to design equipment (that is, plumbing) design talent, that is, will generally participate in architectural design, the wages should be

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

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.
