Are small diameter tubes necessary for increasing the energy efficiency of air conditioners?

No. The system energy efficiency can also be achieved with conventional tubes (such as 3/8 inch diameter tubes) simply by using more tubes and thereby increasing the surface area available for heat transfer. Nevertheless, a penalty is paid in terms of the increased weight of tube material and fin material as well as increased refrigerant volume. In general, if larger diameter tubes are used then a larger coil size is necessary to achieve the same performance and energy efficiency that could be achieved in a more compact system with smaller diameter tubes.

Are the 1, 2 and 5 Cent Euro coins pure copper?

No, they are made from steel coated with a thin layer of copper.

Are weld repairs permissible on Class1 and Class 2 Forgings produced to Def Stan 02-879 Part 2?

The rectification of defects by welding is not permitted on Class 1 and Class 2 forgings.
