The technology focuses on how to efficiently remove heat from a space or substance and

release it elsewhere, usually using refrigerants and compressors. Over time, innovations

in materials and controls have significantly improved how these systems operate,

reducing energy consumption and environmental impact.

The Basics: How Refrigeration Systems Work

To appreciate refrigeration and air conditioning technology 72, it helps to revisit the

refrigeration cycle, which consists of four main components:

Compressor: Compresses the refrigerant, raising its pressure and temperature.
