Abstract
  • A computer simulation program, Controlled Atmosphere Simulation (CAS), was written in Microsoft Visual Basic 3.0, Professional Edition to evaluate energy use by three type of atmosphere generators used in fruit storage warehouses. The program consists of pulldown time and energy use models for a membrane air separator, an ammonia fractionating burner, and a catalytic oxygen burner. Predicted results subsequently became input to an interactive computer program, Fruit Storage Refrigeration Energy Simulation (FruSTRES), which was developed to simulate energy use by cold storage ammonia refrigeration systems. The resulting model package was then used to predict overall annual energy use in fruit storages, based on number and size of rooms, building construction, equipment operation (both refrigeration and CA), commodity stored, storage period(s), and weather conditions. The CAS accurately predicted the pulldown time of each type of equipment under normal operation. The resulting model package (CAS and FruSTRES), will be an invaluable tool in design and analyses of ammonia refrigeration and atmosphere generation systems used in common and controlled atmosphere fruit storages.
