Application Research on Energy Saving Technology of Waste Heat Recovery and Defrosting for Low Temperature Cold Storage

In this paper, a glycol defrosting system using waste heat exhaust from refrigeration compressor is designed. The numerical model, transfer model and frost growth were established. thickness, consumption ethylene flow rate calculated, the pipeline was project solves problems of traditional cold storage, such as high power consumption, fluctuation storage temperature, hidden danger safety, condensation temperature low efficiency system.
