Design and Analysis on Energy Recovery System of Aquatic Product Comprehensive Process Factory

To reduce energy consumption and carbon emission, this paper designs energy recovery technology of aquatic products processing plant, including refrigeration heat recovery and ice-making cooling recovery. Three heat recovery plans are compared and analyzed, while two ways about cooling recovery of ice-melting pool are compared. The results of analysis show that different heat recovery modes have different energy efficiency. Sensible heat recovery process is simple and practical. Combined recovery of sensible heat and heating pump latent heat is complicated. Heat recovery efficiency of total heat recovery is affected by inlet and outlet temperature of recovered water. Besides the volume of recovered water is defined without adjustment and the quality of water is unguaranteed. Indirect cooling recovery of ice-melting pool is a convenient and practical method which performs better in summer than winter.
