It is found that the longitudinal rectangular fins have excellent heat transfer performance and are easy to manufacture. The effect of fins on heat transfer enhancement is closely related to the number of fins and its geometric parameters. Keywords: thermal energy storage; phase change material; ...
This is an easy part, but if you don't have experience it will take time. You have performed a pressure test and vacuuming. It's time to charge your system. Let's say you don't know how to calculate the amount of refrigerant in a recently built system, so follow next steps: ...
