Which dangerous outcome occurs when an HVAC system refrigerant filter becomes blocked?

💡 Explanation

Compressor oil starvation occurs because the blocked filter prevents oil circulation, therefore compressor bearings overheat and seize, rather than evaporator cracking which results from thermal stress or refrigerant decomposition from external factors.

• Which risk increases when reinforced concrete column experiences sustained compressive load exceeding critical buckling load?
• Which risk increases when transformer oil containment systems lack sufficient capacity during a rupture?
• Which risk rapidly increases when a hydraulic servo-valve operating frequency nears structural resonance frequency creating cavitation at constrictions?
• Which risk increases when a ground fault develops in a three-phase transformer's secondary circuit without proper grounding?
• Which outcome occurs when a residential grid-tied solar system exports excessive reactive power to the electrical grid?
• Which consequence results when seismic loading exceeds the shear capacity of a concrete beam reinforced only with longitudinal rebar?
