The air conditioner can generate condensation at different parts in the operation process, and the condensation mechanism is as follows: when the ambient temperature is lower than the dew point temperature at that time, water vapor in the air is condensed into water drops. The dew point temperature is a temperature required for the water vapor in the air to reach a saturated state and liquefy into dew. The relative humidity is the percentage of the amount of water vapor contained in the air at a certain point in a certain time to the saturated amount of water vapor at the air temperature. When the air conditioner is in a refrigeration mode, under the condition of a certain ambient temperature, the larger the relative humidity is, the more easily condensed water is generated; the closer the dew point temperature is to the ambient air temperature, the more likely condensation occurs; the dew point temperature at which condensation forms is always lower than the ambient temperature, regardless of the temperature in the air. Therefore, in order to prevent the occurrence of condensation, it is necessary to keep the surface temperature of the portion where condensation is not allowed to occur higher than the condensation point temperature of the ambient air.

The embodiment is studied the reason that produces the condensation on split type cabinet-type air outlet window left and right sides curb plate of a certain model and the panel, and the research discovery is because the internal surface has pasted the heat preservation sponge, has got rid of the wind-cold in the wind channel and has blown the curb plate on, conducts the surface after the temperature is less than the reason that the dew point produced the condensation.

Referring to fig. 1 and 2, because the air outlet window foam 1 on the air outlet window 6 is assembled with the panel 3 and then assembled with the side plate 2, the design consideration is allowance, the gap (2.5) between the air outlet window foam 1 and the side plate 2, in order to prevent cold air leakage, sponge 4 with the thickness of 3mm is adhered on the air outlet window 6 (made of PU sponge), the diameters of the PU sponge cells are mixed and distributed, the opening ratio is very large, the air permeability is certain, 2L-shaped channels can be seen from fig. 2, cold air with certain pressure can still leak to the inner surface of the panel 3 and the outer surface of the side plate 2 from the channels (as shown in fig. 3), and the inevitable deformation in a certain degree in the production process of plastic parts and sheet metal parts is added, the balance in the manufacturing process and the cost is comprehensively considered, the deformation amount within 2mm in the height direction of the cabinet machine after assembly is controlled, and the panel 3 and the side plate 2 are assembled and positioned in the height direction of the cabinet machine, the sealing effect cannot be well achieved at the local position, adverse factors are superposed to enlarge the air leakage amount, and the refrigeration air is blown to the outer surface of the part through the gap channel to cause the temperature of the local appearance surface to be lower than the dew point temperature to form condensation. This embodiment forms principle and current air conditioner structure based on above-mentioned condensation and designs air conditioner panel structure. As described in detail below.
