A system that uses steam or hot water in place of a compressor to raise the temperature/pressure of the refrigerant is called a/an _____ system.

A system that uses steam or hot water in place of a compressor to raise the temperature/pressure of the refrigerant is called a/an _____ system.

• A. Compression
• B. Refrigeration
• C. Absorption
• D. Centrifugal

Answer: (C)

The system that uses steam or hot water to raise the temperature or pressure of the refrigerant is known as an absorption system. In this type of refrigeration cycle, heat is used to drive the process of cooling, utilizing a refrigerant that is absorbed by a secondary substance, which helps in transferring heat. This distinguishes absorption systems from compression systems, which rely on mechanical compressors to achieve the necessary compression of refrigerants. Absorption systems are often employed in applications where waste heat is readily available or where electric power is scarce or expensive. They can utilize various heat sources, including steam, hot water, or gas flames. This versatility allows them to be effective in different environments and energy contexts. In contrast, the other options pertain to different mechanisms: compression systems rely on mechanical work to increase refrigerant pressure, refrigeration is a more generalized term encompassing various methods including both compression and absorption types, and centrifugal systems utilize high-speed rotary components to achieve refrigerant movement and pressure changes. Therefore, absorption accurately describes the unique mechanism being referenced in the question.
