METHOD AND APPARATUS RELATING TO CONDITIONING OF AIR

摘要

A method of treating air to assist in the keeping of materials such as fruit and vegetables which includes directing air through an evaporator coil (7) of a refrigeration unit to effect a reduction of the temperature of the air to a selected lower temperature, then subsequent to such further cooling of the air, but before directing such treated air across the materials to be preserved, the air is directed through a moisturizer (9) where water in the moisturizer has its water at a temperature substantially the same as the temperature of the air being directed into the moisturizer.
