Inefficient Refrigeration Compressor? It Could be the Pressures

Inefficient Refrigeration Compressor? It Could be the Pressures

Energy Efficiency, HVACR
When refrigeration service technicians respond to one of their clients' service calls, they tend to find the same issues over and over. The most common, and obvious, reason for a service call is a space temperature that is too warm. And, just as common, is suction pressure and/or head pressure being involved in the cause. Often, the refrigeration system will still run, but it'll run inefficiently because the suction pressure is too high while the head pressure is simultaneously too low.   This poses a risk to product quality, integrity, and safety.   On the outset, this exact issue may not be easily observed because, again, the system will call for cooling as it should but it won't be doing so in an effective or efficient manner. In such cases,…
