Is it better to use copper or aluminum tubes for commercial fridge?

For commercial fridge, cold storage and other refrigeration equipment, piping is an indispensable accessory, we all know that the refrigeration system is the core component of the compressor, the need to use high-quality brand compressor, but many times will ignore the similar copper tube such an insignificant part. For users, the new freezer using copper or aluminum tubes can be normal refrigeration, there is no difference. Then the use of copper or aluminum tube good cooler? In fact, the difference is very big, the following reasons.

From the thermal conductivity, copper tube to obviously have in aluminum or galvanized tube, so that copper in the refrigeration system for heat exchange or thermal conductivity better; and aluminum or galvanized tube thermal conductivity is poor, the performance is not as good as copper. From the aspect of corrosion resistance, copper is also significantly better than aluminum or galvanized tube, for the use of copper refrigeration cabinet, not easy to appear refrigerant leakage and not refrigeration, can be used for a long time, but aluminum or galvanized tube, the use of 1, 2 years may be corrosive leakage. Because the cabinet body and insulation layer, so once the corrosion leakage, it is difficult to repair, the whole freezer may be scrapped.

From the above points performance comparison can be seen, copper tube has obvious advantages, so the use of copper cabinet good. But the copper tube also has its own disadvantages, that is, the price will be higher than the aluminum or galvanized tube. So only the regular refrigeration equipment manufacturers, will use copper, and small manufacturers of cold cabinet products, in order to reduce costs to low impact on the market, will choose aluminum or galvanized pipe to replace the copper, the life of such cold cabinet products may only 1, 2 years, if coupled with other refrigeration accessories, the entire cold cabinet products than the regular refrigeration equipment manufacturers will be cheaper than the production of cold cabinets hundreds or even thousands of dollars. So users in the choice of freezer products, be sure to choose the formal refrigeration equipment manufacturers. When choosing a cooler, consider the price at the same time, you should also consider the quality of the product. Low price has low price reason, high price has high price reason.
