What's the difference between a refrigerator and a copper tube?
Now appliances to the countryside are aluminum tubesIf it doesn't wear well, throw it away
Aluminum pipe is not corrosion resistant, short life, but low cost, and copper tube corrosion resistance, long life, but the original high.
Price。 The price of copper tube is higher than that of aluminium tube, so the cost of using all copper tube refrigerator will be raised greatly.Weight. Copper has a density greater than aluminum. Aluminum can reduce the weight of the refrigerator.Corrosion resistance. The corrosion resistance of copper is greater than that of aluminum. Aluminum tube in the sealed refrigerator, easy to be corroded by water and lead to refrigerant leakage, and copper corrosion resistance is stronger, unfavorable corrosion.Thermal conductivity. The heat conductivity of the copper tube is better than that of the aluminum tube, so the heat transfer effect of the refrigerator with the copper tube is good.Generally speaking, physical properties of copper is better than aluminum, but considering the cost factors, now basically do not use the refrigerator refrigeration system used in all aluminum tube, to make the refrigerator, only the key parts, such as capillary, compressor outlet for brass.
