An energy exchanger is provided. The exchanger includes a housing having a front and a back. A plurality of panels forming desiccant channels extend from the front to the back of the housing. Air channels are formed between adjacent panels. The air channels are configured to direct an air stream in a direction from the front of the housing to the back of the housing. A desiccant inlet is provided in flow communication with the desiccant channels. A desiccant outlet is provided in flow communication with the desiccant channels. The desiccant channels are configured to channel desiccant from the desiccant inlet to the desiccant outlet in at least one of a counter-flow or cross-flow direction with respect to the direction of the air stream.

Liquid-to-air membrane energy exchanger

An air delivery system may include a housing, a first liquid-to-air membrane energy exchanger (LAMEE), and a desiccant storage tank. The housing includes a supply air channel and an exhaust air channel. The first LAMEE may be an exhaust LAMEE disposed within an exhaust air channel of the housing. The exhaust LAMEE is configured to receive the outside air during a desiccant regeneration mode in order to regenerate desiccant within the exhaust LAMEE. The desiccant storage tank is in communication with the exhaust LAMEE. The exhaust LAMEE is configured to store regenerated desiccant within the desiccant storage tank. The regenerated desiccant within the desiccant storage tank is configured to be tapped during a normal operation mode.

Control system and method for a liquid desiccant air delivery system

A method of forming a membrane panel configured to be secured within an energy exchange assembly may include forming an outer frame defining a central opening, and integrating a membrane sheet with the outer frame. The membrane sheet spans across the central opening, and is configured to transfer one or both of sensible energy or latent energy therethrough. The integrating operation may include injection-molding the outer frame to edge portions of the membrane sheet. Alternatively, the integrating operation may include laser-bonding, ultrasonically bonding, heat-sealing, or the like, the membrane sheet to the outer frame.

Membrane-integrated energy exchange assembly

A counter flow air-to-air energy exchange assembly may include a plurality of air channel levels configured to allow air to pass therethrough. Each of the air channels may include a spacer layer having a plurality of modular spacer components secured together. At least two of the modular spacer components are identical in size and shape. The spacer layer includes a plurality of air channels. Each of the plurality of air channels extends from an air inlet to an air outlet.

A rotary wheel assembly is configured for use with a system for conditioning air to be supplied to an enclosed structure. The rotary wheel is configured to be positioned within a supply air stream and an exhaust air stream. The assembly includes a cassette frame, a wheel rotatably secured within the cassette frame, and a self-adjusting seal subassembly configured to maintain sealing engagement with respect to a surface of the wheel. The self-adjusting seal subassembly includes at least one seal member.

An air delivery system is configured to deliver air to an enclosed structure and may include at least one air channel configured to deliver air to or receive air from the enclosed structure, at least one component disposed within the at least one air channel, and at least one flame-blocking filter removably and adjustably secured within the at least one air channel. The at least one flame-blocking filter is configured to isolate the at least one component from a source of excessive temperature or flames. The at least one flame-blocking filter is configured to allow air to pass therethrough under normal operating conditions, and to block air and flames from passing therethrough when exposed to the excessive temperature or the flames.

A method of forming an energy exchange assembly may include forming a plurality of creases and a plurality of slits in a membrane sheet according to a predefined pattern, positioning a first spacer on top of a first forming area of the membrane sheet, folding the membrane sheet over a top of the first spacer so that a second forming area is positioned over the top of the first spacer, sealing a first portion of the first forming area to a first outer lateral wall of the first spacer, and positioning a second spacer on top of the second forming area, thereby stacking the second spacer over the first spacer.
