Fresh air assembly and air conditioner

Abstract

The present invention discloses a fresh air assembly and an air conditioner. Fresh air is introduced to one side of evaporators, flows into a wind chamber from the evaporators, and finally is discharged to the indoor. The fresh air undergoes dehumidification, cooling, or heating processing performed by the evaporators, and therefore functions of the evaporators are fully utilized. A dehumidifier module is removed, which reduces noise, decreases overall energy consumption and costs, and makes cleaning and maintenance more convenient.
