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:Home 2 air conditioning is the cooling of electricity or heating electricity? How much power is spent in hours
No, polycyclic aromatic should be anthraquinone This is certainly not all of the hydrocarbons are carcinogenic
Q:External wall insulation method of operation There are several combinations of materials
Seeking the existing building construction specifications Daquan! The The @ .com
Q:Space blowing wind is not cold how is it?
Common points are all sandwich panels, with a hard protective layer, the difference is the middle of the different materials, such as polystyrene board, polyurethane board. Polystyrene board which is the most common, because the price is cheap, easy to use so the use of more, but if the temperature is more than the requirements of the chicken inertia glycosylation moxibustion slim faint words, polystyrene board is not satisfied , So there is a polyurethane sandwich panels, polyurethane thermal conductivity of less than 0.. in the existing insulation materials, large quantities of processing, be the best. But because of its process is more complex, and the cost is relatively high, so with less, the common combination of cold storage and the like, I believe that with the economic and technological development, polyurethane sandwich board market share will be more and more High
Q:Air conditioning ventilation when the sound is a big reason
No matter, it is best to cut the distance between the material and the roof, like an arbor. Otherwise it is not foam board with it
Q:HVAC Heating: What are the main components of the air distribution system?
The reasons are the following: 1. Household electricity is not enough, can not start the compressor, so in the heating state can only be ventilated state, cooling the state directly jump electricity; 2. See if you are reported failure, Code to determine the need for on-site inspection in order to know the specific situation; 3. Four-way valve should be no problem, do not just believe that this is the problem Oh; help your words to adopt
Q:Public building design, the building structure and water is generally designed by the Architectural Design Institute, air conditioning and ventilation is based on the design of the interior? Or first air conditioning ventilation?
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,
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.
Q:The United States direct mail dyson hp01 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:Single cold air conditioning function can not change the cold and warm?
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.
