Which type of refrigeration system typically requires multiple evaporators?

A multi-zone refrigeration system is designed to serve multiple spaces or zones, each requiring different temperature and humidity controls. This system typically incorporates multiple evaporators to cater to the distinct thermal needs of each zone. Having separate evaporators allows for precise temperature management, as each can be controlled independently based on the specific requirements of its designated area. This flexibility is particularly advantageous in residential or commercial applications where varying usage patterns may necessitate different cooling levels in different rooms or zones.

In contrast, a single-zone system is generally designed to handle one space and therefore utilizes a single evaporator. Centralized systems may also utilize one or a few evaporators but are typically focused on large areas with uniform cooling requirements. Hybrid systems blend characteristics of distinct refrigeration approaches but do not inherently necessitate multiple evaporators for functionality. Hence, the multi-zone system is the most suitable choice for scenarios requiring multiple evaporators.
