  • Multimode solar energy collector and process
    Patent number: 4210463
    Abstract: A solar energy collector providing both concentrating-tracking functions and non-concentrating diffuse absorption functions in a single unit. The solar energy collector and process may provide both a higher temperature heat transfer fluid and a lower temperature heat transfer fluid for utilization in various processes, such as environmental conditioning, which may advantageously utilize thermal energy of two different temperatures. The solar energy thermal collector and process of this invention provides a high temperature thermal output in combination with a simplified tracking capability.
    Type: Grant
