Which system uses a compressor to manage temperature fluctuations across several cases?

The correct answer highlights the use of a compressor in managing temperature across various cases effectively. A multiple-evaporator system is specifically designed to handle different temperature settings and needs across multiple displays or storage areas, such as in a grocery or convenience store setting. Each evaporator can operate independently, allowing precise temperature control that is essential for preserving different types of products that may require various refrigeration conditions.

In this type of system, all evaporators connect back to a central compressor, which circulates refrigerant through each unit as needed. This arrangement allows the system to adapt to fluctuating demands—if one evaporator (or case) requires more cooling, the compressor can respond accordingly, improving energy efficiency and maintaining required temperatures across all cases. This flexibility sets it apart from other systems that may not have the same level of temperature management across multiple areas.
