In a refrigeration system, the performance is heavily influenced by the behavior of the refrigerant throughout its cycle, particularly in relation to the pressure and temperature conditions. When the refrigerant is designed to condense into a liquid in the condenser and then evaporate in the evaporator, disruptions in this process can create issues.

In this specific scenario, if the refrigerant condenses in the compressor, it indicates a failure of the compressor to maintain the necessary low-pressure environment in the evaporator for the refrigerant to fully evaporate before returning to the compressor. This can happen if the system experiences low ambient temperatures, particularly in an unheated basement, where the ambient conditions may cause the refrigerant to condense prematurely.

When the refrigerant condenses in the compressor, it can lead to a number of adverse effects, such as liquid slugging, which can damage the compressor and affect its operation. This situation also means that the refrigerant is not cycling correctly through the system, which directly impacts the heat absorption capabilities of the evaporator. Consequently, if the refrigerant fails to evaporate properly, the heat exchange process in the warmer fixture cannot occur efficiently, resulting in inadequate cooling or heating performance.

Therefore, this behavior of refrigerant condensing in the compressor
