Where are systems with open drive compressors most prone to leak?

• A. At the joint connections
• B. At the evaporator coils
• C. At the shaft seal
• D. At the refrigerant valves

Answer: (C)

Systems with open drive compressors are most prone to leak at the shaft seal due to the nature of their design. An open drive compressor has a rotating shaft that extends outside of the compressor casing. To prevent refrigerant from escaping, the shaft must be sealed where it passes through the housing. Over time, wear and tear, as well as the constant movement of the shaft, can lead to deterioration of this seal. The shaft seal is critical because it directly interfaces with the refrigerant. If it is compromised, the refrigerant can easily leak out, leading to a loss of system efficiency and potentially damaging the environment. Proper maintenance and regular checks of the shaft seal are essential to mitigate leaks in systems equipped with open drive compressors. In contrast, while joint connections, evaporator coils, and refrigerant valves can also experience leaks, the specific design of open drive compressors makes the shaft seal the most vulnerable point for leaks to occur.
