Learning About Learning

 Many times we don’t think about how we learn, which is something we are or should be doing most of our lives. This fact was brought home to me this past winter as I became involved as an instructor in a winter sport I like. As I was learning to be an instructor and understanding how people might learn I could see a correlation between what and how someone is teaching and how people learn.

Automatic Oil Return Systems: Why, When, and How? By Monika Witt, TH. Witt

Safe oil draining is a subject that is well documented in IIAR publications, and workshops dealing with proper oil draining are always well-attended. Removing oil from an ammonia refrigeration system is routine maintenance that nearly every ammonia refrigeration system operator will encounter sooner or later. One major advantage of ammonia systems is that oils are not normally soluble with ammonia and will therefore collect at the lowest spot in the system. However, accumulation of oil is gradual, and the location for accumulation must be suitable, i.e., calm enough, such that oil gets a chance to settle.
