Abstract:

Provided herein is a high intensity discharge light source having a thermally insulative and optically transparent sleeve for maintaining or enhancing a spectral performance parameter. The configuration of the sleeve provides an insulative volume that allows an elevated steady state operating temperature to be reached, even when the light source is cooled. The sleeve is also configured to withstand a bulb failure event, thereby protecting the surrounding environment from falling debris. Also provided herein are methods for dissipating heat from the light source without adversely affecting the bulb operating temperature or the enhanced spectral performance parameter.

Abstract:

Provided herein are optical reflectors having a plurality of specially designed reflective surfaces and geometrical arrangement to provide improved illumination of a target area. Also provided are related methods for growing plants with the optical reflectors described herein. The reflective surfaces provide substantially normally aligned light over the entire target area, thereby minimizing shading issues of conventional optical reflectors. Also disclosed herein are efficient cooling by air and/or fluid that can substantially reduce cooling requirements by conventional air conditioning with attendant power savings.

International Classification:

F24D 3/00
F24J 2/05
F24J 2/52
F24D 3/14

Abstract:

Disclosed herein is a solar thermal collector system that is particularly configured for dual use as a radiant cooling system. In accordance with aspects of a particular embodiment of the invention, the solar thermal collector system includes a solar thermal module having a glazing sheet at a top, exterior surface, and an absorber sheet within the module positioned below and spaced apart from the glazing sheet. The absorber sheet and the glazing sheet are fluidly connected to a fluid handling system, and are configured to carry a working fluid that may be heated in the absorber sheet by the sun to transfer such heat to equipment within the facility in which the system is installed, and to carry the working fluid through the glazing sheet to transfer heat collected from the facility to space. The solar thermal collector module is preferably provided a thermally actuated valve that allows the working fluid to also flow through the glazing sheet, which results in self-regulation of the temperature of the module below a critical design temperature.

F24J 2/24

Abstract:

Disclosed herein is a solar thermal collector system that is particularly configured for installation on a pitched roof of a building. In accordance with aspects of a particular embodiment of the invention, the solar thermal collector system includes a solar thermal collector module having a glazing sheet at a top, exterior surface, and an absorber sheet within the module positioned below and spaced apart from the glazing sheet. At least the absorber sheet is fluidly connected to a fluid handling system, and carries a working fluid that is heated in the module by the sun and transfers such heat to thermal storage modules by the fluid handling system. The solar thermal collector module is preferably provided a thermally actuated valve that allows the working fluid to also flow through the glazing sheet, which results in self-regulation of the temperature of the module below a critical design temperature.

Abstract:

Disclosed herein is a solar thermal collector system that is particularly configured for installation on a flat roof of a building. In accordance with aspects of a particular embodiment of the invention, the solar thermal collector system includes a solar thermal collector module having a glazing sheet at a top, exterior surface, and an absorber sheet within the module positioned below and spaced apart from the glazing sheet. At least the absorber sheet is fluidly connected to a fluid handling system, and carries a working fluid that is heated in the module by the sun and transfers such heat to equipment connected to the module by the fluid handling system.
