Technical field
Embodiments of the present disclosure relate generally to the energy exchanging systems for adjusting air in enclosed construction, and more
Body it is related to the membrane support assembly suitable for energy exchanger.
Background technique
Enclosed construction, the building moved in, factory etc. generally include for adjusting ambient ventilated air and/or following again
The heating of annular space gas/ventilation/air adjusts (HVAC) system.HVAC system generally includes supply air flow circuit and exhaust airstream stream
Road.It supplies air flow circuit and receives preconditioned air, such as outdoor air or the outdoor air for being mixed with recirculation air, and should
Preconditioned air is guided and is assigned in enclosed construction.Preconditioned air is adjusted by HVAC system in order to provide with required temperature
With the supply air of humidity being discharged into enclosed construction.Air is drained back into the environment except structure by exhaust airstream flow path.
Without energy recovery, it usually needs a large amount of auxiliary energy adjusts supply air, has and required confession
It is especially true in the environment for the extreme outdoor weather conditions for answering the temperature and humidity of air dramatically different.Therefore, energy exchange or
Recovery system is normally used for restoring energy from exhaust airstream flow path.The energy restored from the air in exhaust airstream flow path is used
The energy needed for reducing adjusting supply air.
Traditional energy exchanging system is using the energy being located in supply both air flow circuit and exhaust airstream flow path
Recyclable device (for example, energy wheel and permeable plate heat exchanger) or heat-exchange device (for example, heat wheel,
Plate heat exchanger, thermal pipe exchanger and belt heat exchanger).Liquid-to-air membrane energy exchanger (LAMEE) is by fluidically coupling
Connection, so that liquid desiccant is to be similar to the typical ring using glycol water as the belt heat exchanger for coupling fluid
The mode in row circuit flows between LAMEE.
In general, LAMEE transmits heat and moisture by thin flexible membrane between liquid desiccant and air.It is flat
LAMEE includes a series of alternate liquid desiccants and air duct separated by film.Typically, the fluid passage between film
Interior fluid pressure is higher than the air pressure outside film.Therefore, flexible membrane is intended to be bent outwardly or protrude into air duct.
Air stream is excessively limited in order to avoid protruding due to film, the air duct of LAMEE is phase compared to fluid passage
To wider.In addition, support construction is generally disposed at the amount for limiting film protrusion between film.However, relatively wide air
Channel and support construction usually weaken the performance of LAMEE.In brief, due to biggish air channel width, in air duct
Heat and the resistance of moisture transfer be quite higher, and support construction may block the film delivery areas of significant quantity.Cause
This needs a large amount of membrane area to meet performance objective, and which increase costs, and cause LAMEE larger.In addition, air
Support construction in channel may generate excessive pressure drop, also impact negatively on the runnability and efficiency of LAMEE.
The heat for being transmitted to film from air duct in parallel plate type LAMEE is expressed as by following:
qs=h (Ts-Tm)
Wherein qsIt is the heat flux of the per unit area at film, h is local heat transfer coefficient, TsIt is local film temperatures, with
And TmIt is the local general average temperature of air.For given temperature difference (Ts-Tm), for, heat transmits under the temperature difference
Rate to film depends on carry-over factor h, related to air channel width and air-flow character.Quality (for example, moisture)
Transmitting determined by similar relational expression.That is, mass flux depends on mass transfer coefficient hmAnd overall air flow and
Concentration (for example, humidity) difference between air at surface.The coefficient h and hmFor given channel geometries and stream
Transmitting analogy for dynamic condition by heat and quality be relative to each other.Carry-over factor is by being referred to as the immeasurable of nusselt number
Guiding principle parameter expression at:
Nu=hDh/k
Wherein DhFor the hydraulic diameter of air duct, for parallel-plate, it is equal to twice of air channel width, and k
It is the thermal conductivity of air.Typical LAMEE generates laminar flow in air duct (that is, the not stable air stream of turbulent flow).
Well known LAMEE includes metal, glass or sticking plaster, is placed in air duct to maintain air duct
Width.In addition, metal mesh is used as the additional support structures between film and bar.Metal bar can be folded in the metal in air duct
Between net, metal mesh is folded between bar and film in turn.Under normal circumstances, the longitudinal axis of bar is parallel to air stream.Pass through
The air stream of air duct is typically laminar flow.However, bar generally takes up sizable space in air duct.In addition, having sent out
It is existing, relatively low heat and moisture transfer rate are generated between air duct and film by the laminar air flow of air duct.

2008 secure lock of supporting element interlock feature in place.Alternatively, membrane support 2008 may include recess portion, and 2002 He of bracket
2004 include fixing component.Further alternatively, one in bracket 2002 and 2004 can be with the integrated landform of membrane support 2008
At and molding, and another then passes through interlock feature and is detachably fixed to the membrane support 2008.Relative to shown in Figure 20 and
The interlock feature can be used together with any membrane support assembly shown and described in the application.
Figure 21 shows the isometric view of the fluid-fluid film energy exchanger 2100 according to one embodiment of the disclosure.
Energy exchanger 2100 may include shell 2102, have the base portion 2102 for being connected to upright support 2104, upright support
2104 are connected to upper wall 2106.Fluid inlet 2108 and 2110 and fluid outlet 2112 and 2114 are limited at upright
Between supporting element 2104.As shown in Figure 21, shell 2102 is formed as cube, but it may be alternatively formed to various other shapes.
Multiple films 2120 are longitudinally aligned from fluid inlet 2110 to fluid outlet 2114, and multiple films 2122 are from fluid
Entrance 2108 is longitudinally aligned to fluid outlet 2112.Film 2110 defines therebetween fluid channel 2130, and film 2122 limits therebetween
Fluid channel 2132.Fluid channel 2130 is generally perpendicular to fluid channel 2132.Fluid 2150, such as gas (such as it is empty
Gas), it is by fluid channel 2130 and (all with the fluid 2152 that flows through fluid channel 2132 by film 2120 and 2122
Such as gas (for example, air)) exchange sensible heat and latent heat energy.Film 2120 and 2122 can be (such as any by membrane support assembly
Above-mentioned membrane support assembly) support.Energy exchanger 2100 can be such as air-air film energy exchanger.
As relative to shown in Fig. 1-Figure 21 and as described, embodiment of the disclosure provides support component, generates suitable
In the path for the air for flowing through film surface.Membrane support assembly improves the heat and quality transfering rate in air duct.Film support
Component ensures that air duct prevents film compressed air channel, the amount of control film protrusion, and supports film to seal to reduce leakage
Risk.
Embodiment of the disclosure can be used together with various types of energy exchangers, such as fluid-air, air-sky
Gas or Liquid-liquid film energy exchanger.For example, above-mentioned membrane support assembly can be positioned on air between film or within film or
In fluid passage.
For example, the turbulent flow for providing the heat between the air duct and film of enhancing and mass transfer due to membrane support assembly is empty
Air-flow, above-mentioned membrane support assembly allow the less film surface product in LAMEE.Therefore, because film can be it is smaller, because
Less material can be used and cost of implementation saving in this.In addition, smaller film leads to more compact energy exchanger, so as to cause
Smaller packaging volume, and the flexibility of bigger system configuration and layout.
As explanation as explained above, embodiment of the disclosure, which provides, promotes turbulent air flow logical by air between film
The membrane support assembly in road.Therefore, compared to previously known system, embodiment of the disclosure is provided between air duct and film
The heat and moisture transfer rate of enhancing.
