Detailed Description
In order that the above objects, features and advantages of the invention will be readily understood, a more particular description of the invention will be rendered by reference to specific embodiments thereof which are illustrated in the appended drawings.
Example 1
The structure of the prior art seat crane is generally shown in fig. 1-3, and the prior art seat crane indoor unit generally comprises an outer shell, an air inlet and an air outlet formed on the outer shell, and an evaporator and a fan which are arranged in the outer shell, wherein the evaporator is obliquely arranged in the outer shell, the air outlet is arranged on one side of the evaporator, the air inlet is arranged on one side of the fan, the air outlet and the air inlet are positioned on the same side of the outer shell, a water receiving disc is arranged on the lower side of the evaporator and used for collecting condensed water generated by the evaporator, and the condensed water is timely discharged. When the seat crane chamber is arranged indoors by a seat type installation method, the whole seat crane is arranged along the vertical direction, the air outlet is positioned at the upper part of the seat crane, the evaporator is positioned above the fan, and the evaporator is obliquely arranged above the water receiving disc; when the seat crane chamber is installed indoors through a ceiling-mounted installation method, the seat crane is installed horizontally, the air outlet and the evaporator are positioned at the front end of the seat crane, the fan is positioned at the rear end of the seat crane, and the evaporator is obliquely arranged above the water receiving disc.
In the running process of the seat crane, external air firstly enters the seat crane from the air inlet under the action of the fan, then passes through the evaporator from the air inlet surface of the evaporator, is discharged from the air outlet surface of the evaporator, and finally is blown out from the air outlet. When the surface temperature of the evaporator of the seat crane is lower than the dew point temperature of the inlet air flow, water vapor can condense on the surface of the evaporator to generate condensed water, and at the moment, the condensed water on the surface of the evaporator needs to be timely and completely led out so as to prevent the condensed water from randomly spreading, corroding or rusting internal components of the air conditioner in the air conditioner. In the application, one side of the evaporator, which is accessed by external air, is called an air inlet surface of the evaporator, and one side of the evaporator, which is exhausted by the external air after the external air and the evaporator are subjected to heat exchange, is called an air outlet surface of the evaporator.
