Description

To conserve energy in a refrigeration cycle the heat-rejection apparatus, condensers, and cooling towers must be intelligently applied . Besides considering economical selection to optimize coefficient of performance, consider using the apparatus for additional duties, emphasizing system reliability and low maintenance. Heat rejected in refrigeration has been used for water heating, space heating, reheat for temperature or humidity control, and defrosting. The fans have been used for ventilation.

System load variation should be analyzed with ambient conditions. Power cost, available waste or renewable resource energy, ambient air and water quality, needs for ventilation, and needs for simultaneous heating and cooling should be considered before selecting heat-rejection equipment. Heat-rejection apparatus can also reduce use of refrigeration, including direct cooling by condenser water in winter, pre-cooling of outdoor air, and direct-indirect evaporative cooling systems.
