What defines a limited charge system?

A limited charge system is defined by its design to ensure that the system does not exceed specified design pressure during the full evaporation of the refrigerant. This characteristic is crucial for maintaining safety and operational efficiency, as it prevents over-pressurization, which can lead to system failures or leaks.

In practical terms, this means that the system is engineered and equipped to handle only a predetermined amount of refrigerant. This controlled charge allows the system to function effectively without risking damage or the potential for refrigerant escape into the environment. By optimizing the charge, these systems often provide reliable cooling while minimizing environmental impacts and reducing the likelihood of costly repairs or replacements.

Other choices do not accurately capture the essence of what constitutes a limited charge system, emphasizing aspects like continuous operation or efficiency in ways that are not specific to the limitations on refrigerant that characterize this type of system.
