This period describes the components of the absorption refrigeration cycle. Comparing the absorption refrigeration cycle with the more familiar vapor- compression refrigeration cycle is often an easy way to introduce it. Like the vapor-compression refrigeration cycle, the absorption refrigeration cycle uses the principles of heat transfer and change-of-phase of the refrigerant to produce the refrigeration effect.
Both the vapor-compression and absorption refrigeration cycles accomplish cooling by absorbing heat from one fluid (chilled water) and transferring it to another fluid (cooling water or ambient air). Both cycles circulate refrigerant inside the chiller to transfer this heat from one fluid to the other. Both cycles also include a device to increase the pressure of the refrigerant and an expansion device to maintain the internal pressure difference, which is critical to the overall heat transfer process.
