摘要： The disclosure relates to a heat transfer assembly for a rotary regenerative heat exchanger. The assembly includes a rotor arranged between at least two separated fluid flow passages passing flow axially through the rotor, where each flow passage is connected to a sector part of the rotor. The assembly further includes a plurality of channels in the rotor for flowing a fluid through the rotor, each of the channels is enclosed by heat transfer and heat accumulating surfaces in the rotor, and the heat transfer and heat accumulating surfaces of the channels are made in a material providing an average axial thermal conductivity less than 100 W/mK arranged to reduce the Longitudinal Heat Conductivity of the rotor.

摘要： A basket for an air preheater includes two metallic frames each having two corner pieces and two connector pieces. For each frame, one of the connector pieces is secured to one end of each of the corner pieces and another of the connector pieces is secured to an opposite end of each of the corner pieces thereby forming a rectangular opening in each frame. The basket includes two heavy gauge metallic sheets that are secured to the corner pieces, thereby spacing the frames equally apart from and parallel to one another thereby forming a channel between two of the sheets.

摘要： A rotary heat exchanger through which a first fluid flow—an outside air or inlet air flow, for example—and a second fluid flow—an exit air or outgoing air flow, for example—can flow in a counterflow configuration, has a rotatably mounted rotor (5) that has a first flow sector for the first fluid flow and a second flow sector for the second fluid flow through which the rotor (5) passes during a rotation, a frame in which the rotor (5) is rotatably supported, and a sealing assembly (9) by means of which an inflow side of the first fluid flow and an outflow side of the second fluid flow can be separated from the outflow side of the first fluid flow and from an inflow side of the second fluid flow, respectively. In order to simplify the sealing assembly, with the aim being that a reliable seal between the inflow and outflow sides of the two fluid flows be automatically ensured during operation of the rotary heat exchanger, it is proposed that the sealing assembly (9) have a first seal (12) that bears sealingly against the side of a partition (10) directed upstream into the first fluid flow (2), and a second seal (13) that bears sealingly against the side of the same partition (10) directed upstream into the second fluid flow (3).

摘要： A rotary pre-heater having a cold-end rotor and a hot-end rotor including an insulation assembly including a plurality of elongate retainer elements. Each of the retainer elements has a root end adapted to be held in fixed relationship to the cold-end rotor and a distal end proximate to the hot-end rotor. Portions of each of the plurality of retainer elements are adapted for circumferential movement.

摘要： The present invention generally relates to a method for manufacturing phase change material (PCM) pellets. The method includes providing a melt composition, including paraffin and a polymer. The paraffin has a melt point of between about 10° C. and about 50° C., and more preferably between about 18° C. and about 28° C. In one embodiment, the melt composition includes various additives, such as a flame retardant. The method further includes forming the melt composition into PCM pellets. The method further may include the step of cooling the melt to increase the melt viscosity before pelletizing. Further, PCM compounds are provided having an organic PCM and a polymer. Methods are provided to convert the PCM compounds into various form-stable PCMs. A method of coating the PCMs is included to provide PCMs with substantially no paraffin seepage and with ignition resistance properties.

摘要： An energy exchange system includes a supply flow path including a central sub-path connected to a bypass sub-path that is, in turn, connected to a delivery sub-path that connects to the enclosed structure. A sensible heat exchanger configured to condition the supply air is disposed within the central sub-path. The bypass sub-path connects to the central sub-path upstream from the sensible heat exchanger within the central sub-path. A first coil configured to further condition the supply air is disposed within the central sub-path downstream from the sensible heat exchanger. A bypass damper is disposed within the bypass sub-path. The bypass damper is configured to be selectively opened and closed. The bypass damper allows at least a portion of the supply air to pass through the bypass sub-path into the delivery sub-path and bypass the sensible heat exchanger and the first coil when the bypass damper is open.
