摘要： Systems and methods are disclosed herein for a three-fluid liquid-to-air membrane energy exchanger (LAMEE) to condition air (a first overall fluid). A liquid panel assembly used in the LAMEE can include a first fluid circuit for a first cooling fluid (a second overall fluid) and a second fluid circuit for a second cooling fluid (a third overall fluid). The first cooling fluid, also referred to herein as a desiccant, can be configured to circulate through the liquid panel assembly and condition an air stream passing through the LAMEE. The second cooling fluid, also referred to herein as a coolant, can be configured to also circulate through the panel assembly and reject heat from the first cooling fluid. The second cooling fluid can increase the cooling capacity and overall performance of the LAMEE. The first and second cooling fluids can be separate from each other during circulation through the panel assembly. Low operating pressures of the first fluid circuit can be facilitated by the design of the liquid panel to at least partially offset hydrostatic pressure gain with friction pressure loss of the first cooling fluid.
摘要翻译：本文公开了用于调节空气（第一总体流体）的三流体液体 - 空气膜能量交换器（LAMEE）的系统和方法。在LAMEE中使用的液体面板组件可以包括用于第一冷却流体（第二总体流体）的第一流体回路和用于第二冷却流体（第三总体流体）的第二流体回路。第一冷却流体，这里也称为干燥剂，可以构造成循环通过液体面板组件并调节通过LAMEE的空气流。这里也称为冷却剂的第二冷却流体可以被构造成也可以通过面板组件循环并且从第一冷却流体排出热量。第二个冷却液可以提高LAMEE的冷却能力和整体性能。在循环通过面板组件时，第一和第二冷却流体可以彼此分开。第一流体回路的低工作压力可以通过液面板的设计来促进，以至少部分地抵消流体静压增益与第一冷却流体的摩擦压力损失。

摘要： Systems and methods for providing dehumidification to an enclosed space can include a dehumidification unit in a supply air plenum that receives return air and a regeneration unit in a scavenger air plenum that receives outdoor air. The system can operate in a wet mode and a dry mode, depending on outdoor air conditions and a relative humidity setpoint for the enclosed space. The dehumidification unit and regeneration unit are both operational in the wet mode to dehumidify the return air and regenerate dilute desiccant. In the dry mode, the dehumidification unit and regeneration unit are not needed, and dry outdoor air can be supplied to the enclosed space. A heat recovery system utilizes waste heat from either return air or scavenger air, depending on the operating mode, to heat the outdoor air before it is supplied to the enclosed space or before it is used for regenerating desiccant.

The first LAHX is configured to directly and sensibly cool the heated air from the space to a supply air temperature using a second fluid flowing through the first LAHX. The second LAHX is arranged inside the scavenger plenum downstream of the LAMEE. The second LAHX is configured to receive and cool the second fluid heated by the first LAHX using the scavenger air. The fluid circuit transports the first and second fluids among the LAMEE, the first LAHX, and the second LAHX.

摘要： Conditioning systems and methods for providing cooling to a heat load can include an evaporative cooler arranged in a scavenger plenum with a recovery coil downstream of the evaporative cooler. The conditioning systems can operate in various modes, including an adiabatic mode and an evaporative mode, depending on outdoor air conditions. The systems can operate in a blended mode between the adiabatic mode and the evaporative mode by varying the distribution of return water from the recovery coil into at least partially isolated sections of a storage tank, and selectively directing cold water from the evaporative cooler into the tank. The mix of warm and cold water exiting the tank can be varied to maintain the cold-water supply at or near a set point temperature for the heat load. In an example, the systems can include a pre-cooler in the plenum upstream of the evaporative cooler for pre-conditioning the scavenger air.

摘要： Conditioning systems and methods for providing cooling to a heat load can include an evaporative cooler arranged in a scavenger plenum with a pre-cooler upstream and a recovery coil downstream of the evaporative cooler. Outdoor or scavenger air can be conditioned in the evaporative cooler such that the conditioned scavenger air can provide cooling to a cooling fluid circulating through the recovery coil. The reduced-temperature cooling fluid can provide liquid cooling or air cooling for an enclosed space (for example, a data center) or for one or more devices that are enclosed or open to the atmosphere. Given the design and arrangement of the pre- cooler, evaporative cooler and recovery coil in the plenum, the system can operate in multiple modes. The pre-cooler can be configured to circulate a cooling fluid to condition the scavenger air. The pre-cooler fluid circuit can be coupled or decoupled from a process cooling fluid circuit.

摘要： A liquid to air membrane energy exchanger (LAMEE) can be used as part of a heating and cooling system to transfer heat and moisture between a liquid desiccant and an air stream to condition the temperature and humidity of the air flowing through the LAMEE. The membrane can be a non-porous film having selective permeability for water, but not for other constituents that form the liquid desiccant. The non-porous membrane can allow for use of liquid desiccants, such as glycols, that had been previously determined to be unacceptable or undesirable in these types of applications. In an example, the membrane can be an ion-exchange membrane or pervaporation membrane.

摘要： Disclosed are systems and methods for conditioning air for an enclosed space using a liquid to air membrane energy exchanger (LAMEE) as a pre-dryer for removing moisture from an air stream with a desiccant flowing through the LAMEE. The LAMEE can be arranged inside a plenum configured to receive and condition an air stream. The LAMEE can be used in combination with a regeneration system to recover water from the dilute desiccant exiting the LAMEE for use as make up water for one or more evaporative coolers in the conditioning system. This can reduce or eliminate an external water supply for operation of the one or more evaporative coolers. The conditioning system can operate effectively with only a portion of the dilute desiccant being regenerated. In an example, a mixing tank can be used to mix the dilute desiccant (exiting the LAMEE) with a concentrated desiccant stream from regeneration.

摘要： A hybrid system and method for conditioning air for an enclosed space can include a direct cooling system in combination with an indirect cooling system. The hybrid system can use direct cooling when ambient temperature and humidity levels are such that 100% outdoor air can be delivered to the enclosed space. The hybrid system can use indirect cooling when 100% of the return air can be conditioned using an external cooling unit and then returned to the enclosed space as supply air. The external cooling unit can include an evaporative cooler and operate in a dry mode and a wet mode. The external cooling unit can produce a reduced temperature cooling fluid and provide liquid cooling to the air when the system is operating in the indirect mode, and in some cases, in the direct mode. The hybrid system can operate in a mixed mode in which the external cooling unit is off and a mix of return air and outdoor air can be delivered to the enclosed space.

摘要： A conditioning system includes a first plenum and a second plenum. The second plenum receives heated air from an enclosed space and supplies cooled air to the space. The system also includes a first liquid-to-air membrane energy exchanger (LAMEE1) arranged inside the first plenum. LAMEE1 is configured to use a liquid desiccant to lower an enthalpy of the first air stream. A LAMEE2 is arranged inside the first plenum downstream of LAMEE1. LAMEE2 is configured to use the first air stream to evaporatively cool water flowing through LAMEE2. A first LAHX (LAHX1) is arranged inside the second plenum. LAHX1 is configured to directly and sensibly cool the second air stream using a first cooling fluid. A second LAHX (LAHX2) is in fluid communication with LAMEE1 and is configured to receive the liquid desiccant from LAMEE1 and cool the liquid desiccant using outdoor air.
