Q:Why can the inner spiral copper tube improve the heat dissipation?
And from the high temperature gas liquid contact area becomes larger
Q:Air conditioner outdoor unit copper leakage 25
In accordance with the state's provisions on the safe use of electricity, all household appliances need reliable grounding.When the frequency conversion air conditioning works, the air conditioner shell, the copper tube and so on will have the induction electricity because of the frequency converter work, when does not have the ground wire, the human body can have the feeling.Frequency converter work will certainly produce induction, people feel there will feel.Induction is not electrical leakage, as for your machine is not leakage, and now can not be determined, need on-site inspection.AskHow will I know if the machine is in question when they come to check it tomorrow? Afraid they do not say, afraid of trouble, do not want to change for me (just bought), just give me a ground wireChasing the answerThe ground wire is not random, you live, if it is in recent years, new buildings, should have the ground wire in line with the requirements.It is very simple to check whether the machine is leak or not. Use a shake meter to measure the resistance to the ground.
Q:What are the advantages of a copper tube radiator over other radiators?
Danai copper pipe convection radiator has advantages over other radiator is:Good thermal performance, the heat transfer speedThe utility model has the advantages of small size, light product, convenient construction and installation, and small occupation areaHigh water resistance and wide tolerance rangeIt has a long life, and basically doesn't need to change when you buy itStrong corrosion resistance
Q:Air conditioning copper tube lengthens 5 meters again, can affect the refrigeration and the heating effect?
The lengthening of air conditioner copper tube has certain influence on the refrigeration and heating, and the influence degree is related to the lengthened length of the copper pipe. When the lengthened length of copper tube is longer, the refrigerant should be added. Of course, after the copper tube lengthened, the pressure drop on the refrigerant also increased, so that the air conditioner deviated from the design point of work, but the impact is not great.
Q:Outside of air conditioning machine copper pipe freezes and does not refrigerate what reason is it?
Galanz's air conditioning, outside the machine top of the small copper pipe icing, the machine has the wind not refrigeration (last week just added fluorine)
Q:Aluminum tube copper 1216 what does it mean?
12161418 aluminum plastic tubes are: 1216 for 4 in charge, in the outer diameter: 12. Internal diameter: 161418 to 5, in outer diameter: 14. Internal diameter: 181620 to 6, in outer diameter: 16. Inside diameter: 20, I am aluminum plastic pipe factory, so I know better.
Q:The brass of 42 to 6.4 of each pipe diameter approximately every 100 meters?
Copper pipe is the best water supply pipeline.Copper tube (outer diameter thickness) * thickness *0.02796Brass tube (outer diameter thickness) * thickness *0.0267That's theoretical weight per meter.
Q:Is the refrigerator copper tube good or aluminum tube good?
The durable said copper compared with aluminum or galvanized iron pipe is better because copper refrigerator can not prone to intermittent use of refrigerant leakage and not refrigeration but not to say that the refrigerator will not leak brass or not bad as in previous years the brand refrigerator production Shangling all adopt copper tube leak many tube refrigerator if hot days before the cold stop for a year for two or three months without other time on it if the continuous use case is not easily broken like before the production of Shuanglu Wanbao service for more than fifteen years and not the problem much as long as the production process standards regardless of what tube refrigerator quality can be (a part of consumers you say how good the brass refrigerator is not necessarily like aluminum printing blown paint evaporator from the actual use of maintenance experience in Party The surface is better than the copper tube, and there is hardly any refrigerator produced by the national standard copper tube on the market at present
Q:How do you calculate the length of the refrigerator evaporator when you replace the refrigerator evaporator?
Generally use 6 copper tube, 16 meters or soFormula for calculating new tube length of refrigerator evaporatorTotal length of pipe = length of freezer room + length of cold storage roomFreezing chamber length =1/3, total volume (L) * 0.148 M / LRefrigerating chamber length =2/3, total volume (L) * 0.03 M / LTest method for capillary lengthThe process of open tube, high pressure pipe is connected with a pressure meter is connected with one end of the capillary, dry filter, the other end is not welded, start the compressor, if the steady pressure gauge at about 0.98-----1.177Mpa, can be considered appropriate, the pressure is too high to cut a little pressure, hour plus a short trial, until the appropriate date, then the capillary and an evaporator connected. Then vacuum pumping and filling refrigerant.
Q:Is the air conditioner used by the main engine of the AUX copper tube?
Copper tube.1. air conditioner has two sizes of connecting pipes, and the thick ones are called big tubes. The fine ones are called small tubes. The function is to connect the inner and outer machines to form a closed system, and the refrigerant can circulate in the inner and outer machines.
