Which consequence results when a chiller's refrigerant loses non-condensable gas purge?

💡 Explanation

Increased back pressure at compressor arises because non-condensables like air raise total presssure. This requires higher compressor effort, therefore leading to increased back pressure, rather than reduced evaporator superheat that might be caused by overcharging.
