ることを課題とする。As shown in FIG. 7, a parallel flow type air-conditioning heat exchanger in which a large number of tubes 20 are arranged in parallel, and a refrigerant flows through each of the tubes 20 at the same time via an inlet-side header 17. When used as an evaporator, a superheat section
14 is formed. That is, in the vicinity of the outlet side of the tube 20, the refrigerant completely becomes a gaseous phase,
It has become. Therefore, the latent heat of evaporation of the refrigerant cannot be used there. Therefore, the cooling capacity of the airflow flowing through the superheat unit 14 is reduced, and dehumidification cannot be performed completely in that portion. Then, the air that has passed through the superheat unit 14 is cooled by the cool air near the fan 19, and condensed water is generated in that part, and the condensed water is cooled by the fan.
Due to 19, there is a risk that water will be released from the outlet as water droplets into the room. Therefore, an object of the present invention is to provide a parallel flow air conditioner heat exchanger for air-conditioning, which can reliably prevent a so-called water jump phenomenon in which water droplets are discharged from an outlet.
