One common access valve initially used is some type of saddle valve. These valves are convenient and generally easy to install, but they are not usually considered to be a long-term type of valve and generally should not be left on a system permanently.
Keeping any kind of air conditioning or refrigeration coil clean is important for proper heat exchange, and microchannel coils are no exception. As these types of coils continue to grow in popularity, technicians should know that the microchannel cleaning procedures can differ from those for cleaning standard fin-and-tube coils.
DOE proposes prescribing energy conservation standards for certain categories of walk-in cooler and freezer refrigeration systems and plans to hold a public meeting to receive comment on these proposed standards along with their accompanying analyses.
