Technical field
Embodiment of the present disclosure relates generally to the energy exchanging system for regulating air in enclosed construction, and relates more specifically to the film supporting component being suitable for energy exchanger.
Background technology
Enclosed construction, heating/ventilation/air that the building of such as moving in, factory etc. generally include for regulating ambient ventilated air and/or recirculation air regulates (HVAC) system.HVAC system generally includes supply air flow circuit and exhaust airstream stream.Supply air flow circuit receives preconditioned air, such as outdoor air or be mixed with the outdoor air of recirculation air, and is guided by this preconditioned air and be assigned in enclosed construction.Preconditioned air is regulated by HVAC system has the temperature required and supply air be discharged in enclosed construction that is humidity to provide.Air venting is got back to the environment outside structure by exhaust airstream stream.When not having energy regenerating, a large amount of auxiliary energies is usually needed to regulate supply air, especially true in the environment with the extreme outdoor weather conditions significantly different from the temperature and humidity of required supply air.Therefore, energy exchange or recovery system are normally used for recovering energy from exhaust airstream stream.From exhaust airstream stream air recover energy for reduce regulate supply air needed for energy.
Traditional energy exchanging system can utilize be positioned at supply air flow circuit and exhaust airstream stream in energy recycle device (such as, energy wheel and permeable plate heat exchanger) or heat-exchange device (such as, heat wheel, plate heat exchanger, thermal pipe interchanger and belt heat exchanger).Liquid-to-air membrane energy exchanger (LAMEE) is fluidically coupled, and adopts glycol water to flow between LAMEE as the mode of circulating loop of the belt heat exchanger being coupled fluid to make liquid desiccant to be similar to typical case.
Usually, LAMEE is by thin flexible membrane transferring heat and moisture between liquid desiccant and air.Flat LAMEE comprises a series of liquid desiccant that replaces and air duct separated by film.Typically, the fluid pressure in the fluid passage between film is higher than the air pressure of film outside.Therefore, flexible membrane trends towards being bent outwardly or protruding in air duct.
In order to avoid excessively limiting air stream because film protrudes, the air duct of LAMEE is relatively wide compared to fluid passage.In addition, supporting construction is arranged between film usually to limit the amount of film protrusion.But relatively wide air duct and supporting construction weaken the performance of LAMEE usually.In brief, due to larger air channel width, the heat in air duct and the resistance of moisture transfer are quite higher, and supporting construction may block the film delivery areas of significant quantity.Therefore, in order to meet performance objective, needing a large amount of membrane areas, and which increasing cost, and cause LAMEE larger.In addition, the supporting construction in air duct may produce excessive pressure drop, and it also adversely affects runnability and the efficiency of LAMEE.
The heat being delivered to film in parallel plate type LAMEE from air duct is expressed as by following:
q s＝h(T s-T m)
Wherein q sbe the heat flux of the per unit area at film place, h is localized heat carry-over factor, T slocal film temperatures, and T mit is the local general average temperature of air.For given temperature difference (T s-T m), the speed that heat is delivered to film under this temperature difference depends on carry-over factor h, and it is relevant to air channel width and air-flow character.The transmission of quality (such as, moisture) is determined by similar relational expression.That is, mass flux depends on mass transfer coefficient h m, and overall air flow and the concentration between the air of surface (such as, humidity) difference.Described coefficient h and h mfor given channel geometries for flox condition by the transmission analogy of heat and quality and be relative to each other.Carry-over factor is expressed as by the dimensionless group being called as nusselt number:
Nu＝hD h/k
Wherein D hfor the hydraulic diameter of air duct, concerning parallel-plate, it equals the twice of air channel width, and k is the thermal conductivity of air.Typical LAMEE produces laminar flow (that is, not having the stable air stream of turbulent flow) in air duct.
Known LAMEE comprises metal, glass or sticking plaster, and it is placed in air duct to maintain the width of air duct.In addition, wire netting is used as the additional support structures between film and bar.Metal bar can be folded between the wire netting in air duct, wire netting and then be folded between bar and film.In the ordinary course of things, the longitudinal axis parallel of bar is in air stream.Laminar flow is typically by the air stream of air duct.But bar occupies sizable space in air duct usually.In addition, have been found that and between air duct and film, produce relatively low heat and moisture transfer speed by the laminar-flow air stream of air duct.
