Is it true that a high suction pressure in a refrigeration system indicates high liquid levels in the condenser coil?

A high suction pressure in a refrigeration system is indeed indicative of high liquid levels in the condenser coil. When the liquid refrigerant accumulates in the condenser, it can cause the pressure within the system to rise. This happens because the high liquid level restricts the flow of refrigerant, preventing it from being adequately vaporized and cycled through the system.

In a properly functioning refrigeration system, the condenser should effectively convert gas to liquid, allowing the vaporized refrigerant to exit and maintain lower pressure on the suction side. However, when too much liquid refrigerant is present, it leads to elevated suction pressures. This situation can result in a variety of issues such as inefficient cooling performance, potential liquid slugging in the compressor, and ultimately, damage to the system.

Other answer choices suggest varying levels of uncertainty regarding the relationship between suction pressure and liquid levels in the condenser. However, the clear and direct correlation established in this case supports the assertion that high suction pressure indicates high liquid levels in the condenser coil.
