Choosing the correct line size is very important to the overall success of the installation. Incorrectly sized refrigerant lines can lead to system problems, excessive energy consumption, and higher installation and operation costs.
For maximum efficiency, a bank of compressors should be connected to evaporators operating at similar temperatures. From an operational standpoint, cases of different evaporating temperatures can be connected to the rack; however, this causes a substantial energy loss.
A ton of refrigeration can be defined as the amount of heat removal to produce one ton of ice at 32° from one ton of water at 32°. But what else does it mean?
Refrigeration technicians need to use extreme care when working with torches during the brazing and soldering process. The flames of a torch can easily reach 3,000°F. At this temperature, serious damage can be the result of misuse and carelessness.
