Embodiment approach 1

[0031] The evaporative cooling system 100 described here can cool the process airflow 104 to a wet bulb temperature lower than that of the outdoor air (for example, the cleaning air 110) without requiring dehumidification or supplemental cooling (for example, a cooler) of the outdoor air. temperature. The process airflow 104 may be cooled to a temperature theoretically close to the dew point of outdoor air. Although dehumidification and / or supplemental cooling are not required, the additional operations and / or components can be added to the system 100 to facilitate cooling of the process gas flow 104, as in one or more embodiments described herein.

[0032] figure 2 Yes figure 1 A schematic diagram of an embodiment of the evaporative cooling system 100 shown. figure 2 The illustrated evaporative cooling system 100 includes components that allow the evaporative cooling fluid 114 to cool the process airflow 104 and pre-cool the cleaning airflow 110. In the illustrated embodiment...

Abstract

An evaporative cooling system includes an evaporative cooler liquid-to-air membrane energy exchanger (LAMEE), a first liquid-to-air heat exchanger (LAHE), and a cooling fluid circuit. The evaporative cooler LAMEE is disposed within a scavenger air plenum that is configured to channel a scavenger air stream. The first LAHE is disposed within a process air plenum that is configured to channel a process air stream. The cooling fluid circuit is configured to circulate an evaporative cooling fluid between the evaporative cooler LAMEE and the first LAHE. The evaporative cooler LAMEE is configured to utilize the scavenger air stream to evaporatively cool the cooling fluid. The first LAHE is configured to receive the cooling fluid from the evaporative cooler LAMEE and to allow the cooling fluid to absorb heat from the process air stream to cool the process air stream.

Description

[0001] Cross references to related applications [0002] The present invention claims priority to the US patent application US14 / 187413 entitled "Evaporative Cooling System with Liquid-to-AirMembrane Energy Exchanger" filed on February 4, 2014, said US patent application US14 / 187413 claims the priority of US provisional patent application US61 / 799321 entitled "Evaporative cooling system with liquid-air thin film energy exchanger" filed on March 15, 2013. These two US patent applications are incorporated by reference in their entirety. this. Background technique [0003] The embodiments of the present invention generally relate to an evaporative cooling system and method, and more specifically, the present invention relates to an evaporative cooling system and method that can utilize a liquid-air thin film energy exchanger (LAMEE). [0004] The evaporative cooler cools the supply airflow supplied into the space by evaporation of a cooling fluid (for example, water). As the fluid eva...
