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!

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

Air conditioning heating than the cooling power consumption, power consumption and ambient temperature and set the temperature has a great relationship, the general cooling 1 hour 1-2 degrees, heating if the auxiliary heating about 2-3 degrees. If you want to save the appropriate temperature can be set higher, the general and the ambient temperature difference of about 5 degrees people feel more comfortable, shut off undesirable, not reach the purpose of saving.

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

Aluminum alloy metal shell better than the plastic shell; we all know that most of the market is now charging the lithium battery, lithium battery is the only drawback is the possibility of a long time with the explosion, so the use of aluminum Alloy shell, much better than steel; polymer battery is good, but the price is expensive,

(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: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.
