A Solar Vapor-Compression Refrigerator/Freezer with Grid Backup Power 2003-01-2473

A vapor-compression refrigerator/freezer with solar power and grid-backup power was tested at Johnson Space Center. The refrigerator was used to test three main energy saving devices: 1) solar power with grid-backup, 2) vacuum panel insulation, and 3) phase change material. Refrigerator power consumption and temperature were monitored while various configuration changes were made to the refrigerator. The testing of the refrigerator showed that the concepts had the potential to save energy although several drawbacks were discovered as a result of the tests.
