What does the term "packaged systems" refer to in refrigeration?

The term "packaged systems" in refrigeration refers to comprehensive units that include all components necessary for refrigeration in a single package. This means that everything from the compressor and condenser to the evaporator and control systems is integrated into one complete system, making it convenient for installation and reducing the need for additional equipment. Packaged systems are designed to operate efficiently as a cohesive unit, which simplifies setup and often leads to improved performance and reliability.

In contrast to the other choices, packaged systems are not limited to small units or modular assemblies. They encompass larger, all-in-one solutions that are suited for various applications, including commercial or industrial use. Their design typically allows for easier maintenance and service, as all key components are located within a single framework, eliminating the complexity of assembling individual parts on-site.
