There are two main places where the entire air conditioning system produces condensate: one is the air cooler of the air handling unit, and the other is the end of the air conditioner (such as a wet fan coil). The mechanism of condensate generation is the same. The air handling unit and the terminal of the air conditioner produce condensate for drying fresh air and eliminating indoor wet load, respectively.
(1) The reason why the air treatment unit produces condensed water: When the outdoor air (or the fresh air and the return air are mixed) exchange heat with the air cooler of the air treatment unit to cool the dehumidified air, the wall temperature of the air cooler is lower than that of the outdoor The dew point temperature of the air (or mixed wind), the water vapor contained in the outdoor air (or mixed wind) is precipitated on the wall surface of the surface cooler and condenses. Thus, condensed water is formed. Treatment of condensed water: Connect the condensed water pipe at the condensed water tray to drain the condensed water to a suitable place nearby.
(2) The cause of condensed water at the end of the air conditioner: the air conditioning end exchanges heat with the indoor air to cool and dehumidify the air. Because the wall temperature of the air conditioner end wall is lower than the dew point temperature of the indoor air, the water vapor contained in the indoor air will precipitate out on the air conditioner end wall Condensation, when the dewdrops increase to a certain degree, it will slide down to the condensate tray below the end of the air conditioner, thereby forming condensate. Treatment of condensed water: the treatment of condensed water at the end of the air conditioner There is a special condensed water system in the air-conditioning water system to discharge the condensed water generated at the end of the air conditioner.
