Automotive air conditioning drainer, mainly for the window air conditioner outdoor water and drainage function of chassis, improve the effect of saving energy effect. Working principle: When the air conditioning refrigeration for outdoor heating condition, the drain valve corrugated tube medium temperature by thermal expansion, promote rubber seal air conditioning chassis drain, make air conditioning condensing liquid stored in the outdoor chassis, improve the heat environment of air conditioner condenser, improve the efficiency of refrigeration, thereby reducing energy consumption. Conversely, when the air conditioning heating, outdoor for refrigeration condition, the drain valve corrugated tube medium due to thermal contraction, pull the chassis of the drain rubber parts to open air conditioning, make after the liquid defrosting time of air conditioner condenser discharge chassis, prevent chassis freezes, affect the normal work of the air conditioning.
