When comparing compression and absorption refrigeration systems, which statement is true?

The statement that compression systems are more efficient than absorption systems is well-founded and aligns with established principles in refrigeration technology. Compression refrigeration systems typically utilize a mechanical compressor to cycle refrigerants, allowing for more efficient heat transfer and lower operational costs. These systems make use of energy in a more effective way by leveraging the properties of refrigerants, which undergo phase changes efficiently during heat absorption and rejection.

In contrast, absorption refrigeration systems rely on heat sources, such as gas or waste heat, to drive the refrigeration process. Though they can be advantageous in specific applications, especially where waste heat is available, they generally have lower efficiency in terms of energy utilization compared to mechanical compression systems. Thus, the efficiency advantage holds true—the mechanical nature of compression systems enables them to deliver more effective cooling for a given energy input.

Understanding the efficiencies of these systems is crucial for making informed decisions regarding which technology to utilize in different scenarios, whether for industrial refrigeration, commercial cooling, or even residential applications.
