PREDICTION OF THE ENERGY CONSUMPTION OF HOUSEHOLD REFRIGERATORS AND FREEZERS VIA STEADY-STATE SIMULATION

摘要: Abstract A simplified model to assess the energy performance of vapor compression ‘on–off’ controlled refrigerators is presented herein. The consists first-principles algebraic equations adjusted with experimental information obtained from refrigeration system under study. work consisted controlling and measuring component operating conditions in order gather key for development validation model. methodology showed similar accuracy that using more sophisticated dynamic simulation codes, but lower computational costs. When compared data, predicted AHAM consumption tests within a ±5% deviation band. sensitivity analysis considering number tube rows condenser coil, fins evaporator coil compressor stroke also reported. study was top-mount ‘Combi’ 600-l refrigerator, by temperature fresh-food compartment.
