Read the news that someone bought back after the installation of air conditioning use without refrigeration, the warranty for what the problem is. Then someone will be outside the machine is connected with the inner pipe machine open a look, the original pipe covered with copper, aluminum and the inside is to look after the question!? tube can not be used? This is why?
The thermal conductivity of aluminum copper than good and very much. To heat exchange products of copper in air conditioning this exactly is that copper is a very ideal material.
Those sinister manufacturers use copper coated aluminum pipe to replace copper. It looks copper, the actual performance is poor far. I do this is the air conditioning itself, refused to copy.
The use of copper can greatly improve the efficiency of air conditioning or refrigeration (heating).But some sinister manufacturers in order to save cost of aluminum tubes used to replace (aluminum cheaper), but for some reason or certification, now more and more consumers know copper than aluminum after.
