Q:Haier air conditioning 1.5P, 3P, 5P, 3P Guiji, copper tube diameter, thank you heroes to the solution
How do you do? Thank you for your inquiryThere are no specific models and specifications are not available. (Haier 3 horses following household air conditioning liquid pipe is 6.0mm 1.5 horse trachea 12.0mm, 3 HP 12.7mm, high-end machine adopts 15.88mm) for reference: 5 pieces of commercial air conditioning products not sure, usually by 9.52mm and 15.88mm.You are welcome to ask questions againWish you a happy working life ~!
Q:paraguard IUD copper...how?
I bled like a stuck pig when I had the Paraguard. My mom said the same thing. I have no idea why they say the IUD might make your periods lighter because for me, it did NOT! I bled like that until I had them remove the darn thing, which was 4-5 months after they placed it.
Q:What does copper smell like?
Copper smells like a penny. It even tastes like one.
Q:What's the effect on copper tube (HVAC) after long storage?
Bill, if you don't know, you shouldn't feel obligated to answer. Copper most definitely age hardens, The speed depends on the heat as well as time. Compression fittings are more likely to leak on age hardened tubing because they can't force it into round and can't compress it or bite into it as easily. I am fighting a group of fittings in my house that are leaking right now. They are all in the hot water immediately out of a water heater that have been around 160-180 deg. for 16 years. The rest of the house is still fine. I cut a new piece of tubing (the same shelf age) and couldn't get it to seat either. I will most like have to replace several fittings and buy new fresh tubing that has not age hardened. I had similar experiences in my first house. All of this is anecdotal based on general engineering knowledge & 45 years experience. I have found oblique references but no direct authoritative references.
Q:Is Copper II Nitrate a pure substance?
It helps to think about it all as a hierarchy beginning with elements. Elements are composed of atoms which all have exactly the same number of protons. Therefore, all the atoms have exactly the same chemical characteristics. NOTE: I was careful to restrict my definition to just protons. An element can have atoms whose numbers of neutrons vary. These are called isotopes, but they are still elements if the number of protons are all the same. This is why Uranium238 and Uranium235 are still the element Uranium. Each isotope has 92 protons. Compounds are composed of only 1 kind of molecule. Molecules are composed of atoms. Mixture is a vague term used to describe something which contains two or more compounds. Seawater is a mixture of the compounds water and salt. You and I are also mixtures. Most things on earth are mixtures. This definition is broken down further into homogeneous and heterogeneous mixtures. In a homogeneous mixture all the molecules or ions are evenly dispersed. Saltwater is a homogeneous mixture. In a heterogeneous mixture this is not the case. Chicken soup is a heterogeneous mixture. Copper (II) nitrate is therefore a compound. However, dissolved in water, it forms a mixture of water molecules and ions.
Q:copper 2 chloride and aluminum chloride >>?
copper 2 chloride and aluminum chloride it is a trick question because copper and aluminum switch it still seams the same it is double replacement cationic
Q:Brass or copper jewelry?
Copper, when worn up against the skin, will turn you green. It reacts with the natural salts in your body. Brass is slightly better but won't have the real shine that pure copper will.
Q:What is copper soluble in and insoluble in?
Copper dissolves in oxdising acids e.g. nitric acid or acids with oxygen i.e. hydrochloric and sulfuric with air bubbled thru. Also dissolves (Reacts) with ammonia solution and amines. Copper is not particularly dangerous but is toxic at certain concentrations ( as is everything) it is however, an essentialy nutrient for plant and animal life.
Q:The length of the copper pipe between the indoor air conditioner and the outdoor host is suitable.
As far as the air conditioning copper pipe is concerned, the pipeline shall not be longer than 15 meters, otherwise the refrigeration effect of the air conditioning connecting pipe will be greatly reduced, and even the refrigeration effect of the air conditioning connecting pipe can hardly be obtained. In serious cases, it may cause overloading of the body until serious damage occurs.Encountered in the actual cannot but in design and construction, air conditioning, brass 15 meters above, will need to increase the cooling capacity, a 1.5 horsepower, the cooling effect will be affected. According to the manufacturing theory of air conditioner, if the air conditioning connecting pipe is too long, it is easy to produce too much load, and it is easy to appear the problem of compressor returning oil, which will affect the service life of the compressor.Therefore, the manufacturers in order to avoid unnecessary loss of consumers do not want to lengthen the construction unit of the air conditioner copper pipe is too long, too long not only affect the air conditioning pipe, cooling effect, but also affect the service life of the refrigeration system.
Q:Copper Hairbrush?
Some dandruff can be the result of a yeast-like fungus called malassezia that naturally lives on the scalps of healthy adults without causing problems. To a small extent, copper may act to kill malassezia as copper has antimicrobial properties include acting as a fungicide. However, I had a dandruff problem I would not relay on a copper hair brush for treatment. There are many more proven treatments available.
