    There are three methods to mechanically introduce outside air into individually occupied areas and rooms. When considering which method to use, the designer should choose a design that minimizes potential maintenance costs and operational problems. Decoupled Ventilation Air: This is the preferred method to use with all LG air conditioning products. From a common Method 1: outside air inlet, filter and pre-treat the air temperature to room neutral conditions, and duct the ventilation air to the ceiling or wall registers in each breathing zone.
