Which parameter indicates the effectiveness of the refrigeration system regarding liquid condensation?

The effectiveness of a refrigeration system in terms of liquid condensation is best indicated by the condensed liquid temperature. This parameter is crucial because it reflects how efficiently the refrigerant has transitioned from a vapor to a liquid state after passing through the condenser. A lower condensed liquid temperature generally indicates that the refrigerant is being adequately cooled and condensed, which is essential for the system to operate effectively.

In a refrigeration cycle, the condensation process is where the refrigerant releases heat and transforms into a liquid. The temperature of the condensed liquid provides insights into the efficiency of this heat exchange process. If the temperature is too high, it may suggest insufficient heat removal, leading to decreased system efficiency and potential operational issues.

Other temperatures, such as discharge temperature, oil temperature, and suction temperature, provide information about different parts of the refrigeration cycle but do not specifically indicate how effectively the condensation process is occurring. These parameters may affect overall system performance but are not direct measures of the liquid condensation efficiency. Thus, the condensed liquid temperature is the most relevant parameter when assessing the effectiveness of condensation within the refrigeration system.
