Solar heating for refrigeration and fluid heating devices

A thermal fluid system comprising:

• a fluid heating device configured for rotation about dual axes and configured to heat a fluid circulated therethrough the fluid heating device comprising:
• a support structure;
• an upright support member;
• an arm portion extending laterally from the upright support member;
• and
• a spine portion offset from the arm portion and extending substantially parallel to the arm portion, wherein the arm portion is pivotable about a season axis extending perpendicular to the upright support member and perpendicular to the arm portion and the spine portion is pivotable about a day axis extending longitudinally along the spine portion;
• a continuous and uninterrupted reflective surface configured to focus sunlight from a sun on a focal axis centered above the reflective surface, the continuous and uninterrupted reflective surface being arranged on a frame supported by the spine;
• a pair of upright support elements each extending upward from the frame at respective ends of the continuous and uninterrupted reflective surface;
• and
• a fluid heating element comprising no more than a single tube secured to and extending between the pair of upright support elements and arranged along the focal axis;
• at least one of:
• a heating subsystem configured to heat an enclosure or material by circulation of heated fluid from the fluid heating device through the heating subsystem;
• or
• a cooling subsystem configured to provide refrigeration, wherein at least a portion of the cooling subsystem is powered by heated fluid from the fluid heating device;
• a controller configured to control the position of the fluid heating device relative to the sun;
• a sensor configured for sensing the temperature of the fluid heating element;
• a temperature sensor configured for sensing a temperature of the heating subsystem or the cooling subsystem, the temperature sensor being in wireless communication with the controller;
• and
• a control valve operable by the controller to control the flow of fluid to the heating subsystem or the cooling subsystem.
