Abstract: Air conditioning product design has a great impact on air conditioning condensation. From the perspective of air conditioning product development and based on the principle of air conditioning condensation, this paper expounds that in the condensation design of some air conditioning products, due to the uneven refrigerant flow of each branch of evaporator, the refrigerant flow of each branch is too small, and the structural design of air conditioning outlet and scavenging blade parts is unreasonable. The condensation phenomenon of air conditioner caused by insufficient sealing between the assembly surface of evaporator and bottom shell. Based on the analysis of thermodynamic principle, it is proposed that the flow path design and air conditioning throttling device design should be paid attention to during development, the structural parts of air outlet should be designed based on the principle of CONDA effect, and the condensation solution of slotting scavenging blades is described. It is suggested to add labyrinth concave convex groove at the coordination between evaporator and shell, so as to increase the tightness and reduce condensation.
