Scaleable capacity indirect evaporative cooler

摘要

A scaleable indirect evaporative cooler system (10) fitted within a container incorporates a plurality of dry and wet passage heat exchangers (30) where the dry passages of the plurality of heat exchangers feed into a common space (32) from which conditioned air is delivered via a delivery fan (40) downstream of the dry passages of the heat exchangers. An exhaust fan 22 draws air from the common space (32) through the wet passages of the heat exchanger to a common exhaust space (34) before being exhausted to atmosphere via the exhaust fan (22).

主权项

1. An indirect evaporative cooler system in which air flow in interspersed wet and dry passages of each of a plurality of evaporative heat exchangers is in respective counter flow, said plurality of evaporative heat exchangers being incorporated in a container and combining for a delivery of relatively large volumes of cool conditioned air, and wherein the air flow through the dry passages is controlled by means of interconnected first cavity spaces downstream of the dry passages held at a required pressure by at least one shared delivery fan in said first cavity spaces and the air flow through the wet passages is controlled by interconnected second cavity spaces held at a predetermined pressure by at least one shared exhaust fan in said second cavity spaces.
