Moisture indicators are typically part of which component in a refrigeration system?

Moisture indicators are primarily found in a sightglass within a refrigeration system. The sightglass serves as a transparent window that allows technicians to visually inspect the refrigerant flow and assess system conditions. Since moisture in the refrigerant can lead to problems such as corrosion and freezing in the system, the inclusion of a moisture indicator in the sightglass is crucial. This indicator typically changes color or visibility when moisture is present, signaling the need for maintenance or repair.

Other components like condensers, evaporators, and pressure sensors play distinct roles in the refrigeration cycle but do not specifically serve as moisture indicators. Condensers are responsible for dissipating heat from the refrigerant, evaporators facilitate heat absorption from the environment, and pressure sensors monitor the pressure levels within the system. However, none of these components specifically provide moisture detection, making the sightglass—the correct answer—the logical choice for where moisture indicators are typically located.
