Modular living
green wall systems are provided that supply water-cooled
heat rejection for building cooling, power generation, industrial, chemical, and other processes that rely on
heat rejection to the ambient environment for their efficient operation.
Warm water from the process requiring
heat rejection is circulated vertically through channels of porous media of the
system and is cooled by evaporative and / or
convective heat transfer to the
ambient air that flows over and / or through the porous media across or counter to the
water flow direction. Cool water leaving the
system is piped to a
heat exchanger of the process to provide the requisite cooling and is returned warm to the modular
green wall system to complete the circulation loop. Modular living
green wall systems may be assembled using
plant modules and
water treatment modules that are nested together to form continuous porous vertical
water flow channels and a water recirculation system. The
plant modules may consist of an inner porous
media layer and an exposed
porous substrate layer attached to each other and a stackable module housing. The
water treatment module may be housed in a compatible stackable housing containing horizontal
layers of
filtration media. These modules are stacked in an
interlocking manner and may be attached to an existing building support structure or alternatively be used to form a free standing living green wall.
