Embodiments include systems and methods for integrated control of environmental conditions in an equipment enclosure. For example, a novel airflow inlet structure can be installed into a primary airflow path of the equipment enclosure. The airflow inlet structure can include an integrated electrostatic filter sub-structure and an integrated electromagnetic radiation (EMR) control sub-structure.

Provided is a solvent separation method and a solvent separation apparatus that make it possible to efficiently retrieve the thermal energy possessed by an exhaust atmosphere released in a solvent-removal step to suppress reductions in a temperature of the exhaust atmosphere. In the solvent separation method and the solvent separation apparatus, a vaporized solvent is removed from a gas while heat-exchange between the gas within a condensation part and the gas within a dust-collection part is conducted by using a heat exchange part that is placed between the condensation part that introduces the gas into a first direction and the dust-collection part that introduce the gas into a second direction opposite to the first direction the gas discharged from a downstream side of the condensation part.
