Modelica analysis of thermally connected residential appliances.

Summary

As the second largest consumer of global primary energy, research to reduce significant energy consumption in the United States can generate meaningful impacts. Household appliances account for the second largest site residential energy consumption at 27%. Thermally integrating most or all of the residential appliances by leveraging waste heat recovery is currently not covered by U.S. federal standards and has not been adequately explored in the literature. Limited studies exist focused only on single appliances connected to waste heat recovery or being thermally integrated. A Modelica model is presented capturing the operation of four major household appliances, namely the refrigerator-freezer (RF), dishwasher (DW), clothes dryer (CD), and clothes washer (CW), as well as their thermal connection to a simple storage tank model to simulate appliances thermally connected. For a fixed schedule, the simulation predicts the amount of energy recovered from the integrated system and explores the impact from varying the storage size or the heat recovery strategy.
