Optimal Configuration of Evaporative Condensers in Refrigerating Plants Based on Part Load

Abstract:

The operating records of a typical industrial refrigeration plant in Xiamen, China are analyzed. Based on the results, the ratio of the heat exhaust of the operating condensers to that of the total condensers is calculated over each time period to obtain the regulation of part load. The energy consumption and the payback period are calculated for two typical refrigerating plants under different schemes based on the regulation of part load. Results show that energy savings will be 53.6% when condensers are optimally configured based on such regulation. The payback period is 0.8-1.7 years in some cases, whilst in other cases there is actually no additional investment required.
