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.
I added the space 18 degrees opened for 5 hours or not cold, we all know how is it? More
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
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!
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.
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
Ventilation is very good, why still have to install fresh air system
You are a single raft toilet wipes Pie Tanzhuang open card would like to confirm what? Contract notarization or. The The If it is contract notarized, generally notary value of 0.25% -0.3%
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
