Which risk escalates significantly when a refrigeration system's refrigerant mass drops below minimum levels?

💡 Explanation

Compressor failure elevates because the inadequate refrigerant results in insufficient cooling and lubrication, triggering the winding thermal runaway; therefore, winding insulation melts rather than remaining within designed parameters as the refrigerant absorbs heat and provides necessary oil circulation.
