A method for fabricating a heat exchange construct is provided.

A method, system, apparatus, and/or device for preheating air for a rooftop air handling unit (RTU). The method, system, apparatus, and/or device may include a barrier system configured to surround the RTU. The barrier system may include a structure to provide a frame for the barrier system, a first barrier configured to connect to a first side of the structure, and a collector configured to connect to a second side of the structure. The method, system, apparatus, and/or device may include a duct configured to connect between the collector and a chamber. The method, system, apparatus, and/or device may include a chamber configured to connect to an air intake hood of the RTU. The chamber may include a first opening to receive air stored in the cavity, a second opening to receive external air, and a diverter configured to switch between a first position and a second position.

Chemical processors are configured to reduce mass, work in conjunction with solar concentrators, and/or house porous inserts in microchannel or mesochannel devices made by additive manufacturing. Methods of making chemical processors containing porous inserts by additive manufacturing are also disclosed.

The present disclosure relates to roofing granules, such as colored solar-reflective roofing granules, and to methods for making and their use in roofing products. One aspect of the disclosure provides a collection of colored solar-reflective roofing granules, wherein substantially each roofing granule includes an inner layer of a porous ceramic material, the pore size and material of the inner layer being selected such that the inner layer is substantially reflective of infrared radiation; and disposed about and substantially surrounding the inner layer, an outer layer of a substantially colored ceramic material, the outer layer of substantially colored ceramic material being substantially transmissive to infrared radiation, the collection of colored solar-reflective roofing granules having a L* of no more than 60 and a solar reflectivity of at least 30%.

A panel (assembly) having an inner panel member (sheet) and an outer panel member (sheet), with the member being secured to the member so that the member applies an outward force to the first member.

A roof mount assembly implements a stabilized fastener matrix which functions to stabilize the fastener connection with a roof. In one embodiment, a base has a one-piece construction with angularly spaced stepped bores. Roofing fasteners each having a flat head are receivable in the bores and securable therein. Plugs each having a flat lower surface are threadably engageable in the threaded bore wherein the flat lower surface of the plug engages the flat head of the fastener. In a second embodiment, the base has a two-part construction comprising a bottom plate and a top plate. The bottom plate has a plurality of arcuate slots which are angularly spaced from one another. Elongated fasteners are received in the slots. A top plate has a crown and a connector projects from the crown. The top plate mounts onto the bottom plate to provide a stabilized connection with the roof. The mount assemblies are also efficiently sealable with the adjoining roof. In one embodiment, the top plate and lower plate mount highly compressible sealant members.

A system for heating a first fluid flow from a first temperature to a second temperature, the system including a hot water supply line for receiving the first fluid flow at a first end and exhausting the first fluid flow at a second end; and a heating system including a heat engine, a thermal battery and a heat exchanger, wherein the thermal battery is configured to be replenished at a point of heat transfer by the heat engine and the hot water supply line is configured to receive heat from the thermal battery via the heat exchanger to elevate the temperature of the first fluid flow from the first temperature to the second temperature.

The present invention describes a polymeric solar heater that has the advantage of being able to be operated at different pressures, from low to high pressure without having to make adjustments or modifications, since it has grooved reinforcement flanges on the outside of the tank, which prevents the movement of some reinforcement elements allowing to increase the baric capacity of the tank, another advantage that characterizes the present invention is that the casing and the tank are made of polymers, which allow the temperature to be kept inside for longer, given their low coefficient of thermal conduction. Another significant advantage of the polymeric solar heater is that the collectors have integrated thermal receptors that allow them to capture thermal energy more easily, in addition to having mechanical reinforcements that increase the resistance of said collectors against impacts.

Disclosed is a system comprising an envelope of a structure, heat pipes and fluid conduits, the envelope of the structure including at least two shells spaced apart from one another which enclose an intermediate space being sealed against an interior and exterior of the structure. First and second pipes, embedded in the exterior-facing and interior-facing shell of the structure, respectively, penetrate the envelope of the structure and together form the heat pipe for the circulation of a fluid to increase, hold or decrease heat transition through the envelope of the structure or affect heat transport into or out of the envelope of the structure.

Ridge vents and deck covers are disclosed that have a fibrous mesh mat and a moisture barrier. The mesh mat may be contoured to define a variety of structures and may have regions of relatively higher fiber density and regions of relatively lower fiber density. Solar cells may be exposed on the ridge vents to collect solar energy when the vents are exposed to sunlight.
