Systems and methods for selectively producing steam from solar collectors and heaters, for processes including enhanced oil recovery. A system in accordance with a particular embodiment includes a water source, a solar collector that includes a collector inlet, a collector outlet, and a plurality of solar concentrators positioned to heat water passing from the collector inlet to the collector outlet, a fuel-fired heater, a steam outlet connected to an oil field injection well, and a water flow network coupled among the water source, the solar collector, the heater, and the steam outlet. The system can further include a controller operatively coupled to the water flow network and programmed with instructions that, when executed, direct at least one portion of the flow through the solar collector and the fuel-fired heater in a first sequence, and direct the at least one portion or a different portion of the flow through the solar collector and the fuel-fired heater in a second sequence different than the first sequence.

The described embodiments provide thermal energy via solar powered heat exchangers. This energy can be implemented to heat hot water or heat residential/commercial structures. Parallel mounted vacuum insulated tubes heat water within a geometric heat transfer piping system. This thermal energy is transferred via a piping system to an insulated tank. A digital controller monitors and controls the temperature of the water within the system as well as provides frost/freezing protection. An electrical active pumping system is connected to the digital controller to circulate water within the solar heat exchanger. The electric active pump can be connected to a solar photovoltaic (electric) panel for reliable and uninterrupted heat/hot water delivery.

A portable solar energy water heating system is provided. The system can include an inflow line having an inlet, at least a portion of the inflow line positionable in a body of water. The system can also include an outflow line having an outlet, at least a portion of the outflow line positionable in the body of water. The system can also include a conduit portion housed in a container housing and a magnifying glass or lens positioned over the conduit portion and configured to direct solar energy onto the conduit portion for heating water flowing therethrough between the inlet and the outlet, thereby providing heated water to the body of water. Optionally, the container portion can be at least partially filled with a substance that retains heat, such that the conduit portion is at least partially submerged in the substance.
摘要:
A system and method for cleaning and cooling solar panels are described. A solar tracker includes a main beam for supporting the solar panels, and nozzles coupled to the main beam. The main beam includes a water channel along its interior which supplies water to the nozzles. The nozzles are positioned to spray water on the collecting surfaces of the solar panels to clean and cool them. The solar tracker may also include gutters to reclaim used water. The solar tracker may include air ducts which direct air across the undersides of the solar panels to cool them.
摘要:
Insulated solar panels provide that provide a solar thermal collector with means for limiting stagnation temperatures and preventing damage include: temperature limiting is provided by the insulated solar panel, isolating internal components from the environment, using passive closed systems within the sealed solar thermal collector, while also allowing alternative implementations as active systems and/or portions of the temperature limiting system outside the sealed solar thermal collector. A heat pipe can be used as a passive thermal switch, where the temperature induced action at a predetermined temperature causes an abrupt transition from a state of thermal isolation to a state of strong thermal coupling. Additionally, a set of siphon circulation pipes provides a passive closed system for temperature limiting.

A hot water feeder in which a solar heat collector is used. The feeder has a first heat exchanger for heating a heat medium by solar heat, a second heat exchanger for heating water in a hot-water tank by the heated heat medium, and a heat exchange volume determination unit. The heat exchange volume determination unit calculates the flow rate of the heat medium circulating between the first and second heat exchangers on the basis of the detected temperature of the heat medium fed to the first heat exchanger and the rotational speed of a heat medium circulation pump, and calculates the heat exchange volume on basis of the flow rate and the temperature difference between the detected temperatures.

A device for using solar energy to heat air. The device can include a hot air panel having a box. The box can include a glazing, a collection plate, and a base layer. The collection plate can be disposed between the glazing and the base layer so as to define a first chamber and a second chamber. The first chamber can be an insulation chamber that can hold air within the box. The second chamber can be a flow chamber that allows air to flow through the box. The box can be further associated with a temperature detection device and a fan.
