A method and apparatus are provided that combine solar technology and agriculture in a symbiotic relationship that optimizes revenue from both sources. An array of reconfigurable solar collector assemblies is deployed in a crop field. As various crops benefit from varying degrees of shade through their development cycles, and are prone to damage from high winds and hail, the array of adaptable, reconfigurable solar collectors is deployed in the crop field and allows for the easy reconfiguration of each solar collector assembly to vary the amount of shade that is applied to the crops below the assembly, and to provide maximum hail and wind protection when necessary.

Methods, systems, and devices are provided for thermal enhancement. Thermal enhancement may include absorbing heat from one or more devices. In some cases, this may improve the efficiency of the one or more devices. In general, a phase transition may be induced in a storage material. The storage material may be combined with a freeze point suppressant in order to reduce its melt point. The mixture may be used to boost the performance of device, such as an electrical generator, a heat engine, a refrigerator, and/or a freezer. The freeze point suppressant and storage material may be separated. By delaying the periods between each stage by prescribed amounts, the methods, systems, and devices may be able to shift the availability of electricity to the user and/or otherwise boost a device at different times in some cases.
摘要:
A steam generator having two vaporization chambers filled with molten metal salts for sequential flash evaporation of preheated atomized water through multiple vaporization tubes in said respective chambers. The molten metal salts are heated by secondary solar thermal input from lens assemblies and primary heat input from U-shaped hot air heating tubes within said vaporization chambers supplied by gas fired tube burners. Steam vapor generated by initial vaporization chamber is re-circulated to the secondary chamber outputting super heated steam. The molten metal vaporization chambers are encased in a single pressure vessel with re-circulation of condensate and multiple heat exchangers within.

A solar powered cooling apparatus utilizes a solar collector to convert radiant energy into heat stored in water. An evacuated chamber houses a dessicant bed and a sprayer which introduces an adsorbate into contact with a heat exchanger conduit extending within the chamber. Evaporation of the adsorbate in contact with the conduit cools a medium circulated within the conduit between the chamber and a chilled water reservoir. The evaporated adsorbate is adsorbed by the dessicant bed until a predetermined temperature or saturation level is reached, at which point, heated water from the solar collector is passed through heat exchanger conduits in the dessicant bed to regenerate the dessicant bed. Iterative adsorption and regeneration cycles maintain the chilled water in a desired temperature range.

A thermal energy collector, intended for a system such as a cooling system of the solar type whose mode of operation includes a phase consisting of adsorption of a fluid by a given material and a subsequent desorption phase, comprises a compartment having an upper surface to be exposed to a source of thermal energy and a bottom surface to be connected to a duct joining the compartment to the aforementioned system, with the adsorptive-desorptive material being placed between these surfaces. To increase the efficiency of the adsorptive-desorptive material, a space is provided between the material and the bottom surface of the compartment, with a supporting layer containing openings being placed beneath the material in order to hold it in place against the upper surface.
摘要:
A bubble pump system capable of delivering heat from a higher to a lower position, particularly useful in a solar heating system is described, in which slugs of liquid and vapor are separated out in a separator and the vapor separated is cooled and condensed by indirect contact with a cooling medium. A splash guard is provided in the condenser to prevent liquid discharged from the liquid/vapor inlet from contacting the condensing medium.
摘要:
A heat storage system intended for long term storage between seasons of surplus heat collected in a solar energy system for example, comprises one or several networks of ducts laid out in an earth pack, e.g. underneath a building to be heated and in between foundation members thereof. The system economizes as to expenditure of space and material, in particular with respect to storage of heat at a relatively low temperature level as is encountered in solar energy systems.
摘要:
An absorption cold and warm water system utilizing solar heat includes a low temperature heat generator using as a heating source low temperature warm water obtained by heating water by the solar heat, a high temperature generator using an ancillary heat source as a heating source when the system runs short of the solar heat, and a low temperature generator. The cold and warm water system is provided with an operation device operative, when the cold and warm water system is in condition in which refrigerating and heating outputs can be provided by using the low temperature warm water, to allow the low temperature warm water to be continuously fed to the cold and warm water system and to control the volume of a solution and a refrigerant in circulation in accordance with temperatures of the cold and warm water, to thereby store the solar heat in the cold and warm water system.
摘要:
An arrangement for transferring heat from an upper level to a lower level by causing a liquid to be heated and evaporated in a first chamber at the upper level thus causing an increase in pressure in the chamber which obliges the fluid to flow, through a heat exchanger positioned at the second level and whereat the liquid liberates heat, back into a second chamber positioned above the first chamber and in communication therewith through a valve which is normally closed but is opened in response to certain pressure differences between said first and second chambers so as to intermittently permit the return of liquid from said second chamber to said first chamber. The pressure cycles generated in the first chamber and the flow of liquid can be used to drive mechanical means.
摘要:
Heat energy is stored chemically in and extracted from an energy accumulator containing a substance which contains less liquid in the charged, high-energy condition of the accumulator than it does in the discharged low-energy condition of the accumulator, which is associated with vapor condensing and generating means which is maintained at a low temperature as compared with the accumulator in which a liquid container is comprised. Vapor is driven off from the accumulator substance and transferred to the vapor condensing and generating means when energy is stored in the accumulator, and is returned to the accumulator when heat energy is extracted therefrom. The system comprising the accumulator and said vapor condensing and generating means is maintained substantially free from other gases than said vapor.
