Abstract
A method of cooling a first airstream employs the steps of dehumidifying a second airstream, injecting water into the dehumidified airstream so as to cool the second airstream, and passing the first and the cooled second airstream through a heat exchanger so as to cool the first airstream. In so doing, the condensate recovered during the dehumidification of the second and/or first airstream is used in the injection step.

A method for cooling and dehumidifying a first air stream, the method comprising the steps:
- A) passing a second air stream through a first coarse particle filter and a first electro-filter for cleaning the second air stream and through a first cavity of an air-dehumidifying apparatus, which is separated by a water vapor permeable structure from a second cavity of the air-dehumidifying apparatus, for dehumidifying the cleaned second air stream and obtaining water as condensate;
- B) injecting water into the dehumidified second air stream for cooling the second air stream,
- C) passing the first air stream through a second coarse particle filter and a second electro-filter for cleaning the first air stream;
- and
- D) passing the first air stream cleaned in step C and the second air stream cleaned, dehumidified and cooled with the steps A and B through a heat exchanger for cooling the first air stream, wherein
- water obtained when dehumidifying the second air stream in step A is used in step B for injecting.
An apparatus for cooling a first air stream, comprising a first coarse particle filter and a first electro-filter for cleaning the first air stream, a second coarse particle filter and a second electro-filter for cleaning a second air stream, an air-dehumidifying apparatus for the cleaned second air stream, having a first cavity and a second cavity, which are separated from each other by a water vapor permeable structure, wherein the second air stream may flow through the first cavity, a condensation water separator, which is connected via a manifold with the second cavity of the air-dehumidifying apparatus for the second air stream, pump means arranged in the manifold, a cooling system, through which the dehumidified second air stream may flow, a conduit and a pressure booster pump arranged in the conduit for feeding water obtained in the condensation water separator to the cooling system, and a heat exchanger for exchanging heat between the cleaned first air stream and the cleaned, dehumidified and cooled second air stream.
