  • Patent number: 10022296
    Abstract: The present invention provides a fluid injection system (11) which transitions between a maintenance mode wherein an outlet (15) is closed and no fluid is discharged through the outlet, and an operation mode, wherein the outlet is open and fluid is discharged through the outlet. The fluid injection system injects a first fluid transported in a first pipeline (21) with a second fluid, wherein there is a temperature differential between the first fluid and the second fluid. The fluid injection system comprises a holding tank (49) for storing the second fluid, a cooling means (35) to cool the second fluid, and a pump (39) for delivering the second fluid into the first pipeline.

  • Publication number: 20100307478
    Abstract: A solar collector temperature control intended for use with a solar collector comprising at least one solar tube (11), the interior of the solar tube in use accommodating a heat exchanger or a like means and/or heat exchange medium, said temperature control comprising a controller and a shield (19), the shield associated with the outer wall of the solar tube and extending for at least a portion of the length of the solar tube, said shield having an angular extent sufficient to extend partially around the solar tube. The shield supported to be rotatable about the central axis of the solar tube between a first position remote from the source of radiation and a second position most proximate the source of radiation.
