  • heat recovery and utilization can be carried out according to the characteristics of cold and hot air, and then the operating mode of the whole machine can be regulated, so as to achieve the effects of energy saving, comfort and power saving.
  • the inside of the housing includes a base, a mixed flow fan, an air duct, a water pan, an evaporator, a regulating mechanism, an upper air port, a lower air port and a top cover.
  • the mixed flow fan is a fan between a centrifugal fan and an axial flow fan, which can output the effects of axial working and centrifugal working, in-depth research on the mixed flow fan shows that, the mixed flow fan has different output conditions under different internal pressures, in the structure shown in the figure, when the internal regulating mechanism is fully opened, the pressure of the internal channel becomes smaller, then the mixed flow fan will do more work in an axial flow mode, as a result, the fan sucks air from the lower air port and supplies the air upward, the air passes through the evaporator from both sides for heat exchange through a middle through hole position of the water pan, and is finally gathered at the upper air port for air supply.
  • the internal regulating mechanism When the internal regulating mechanism is closed to a necking, the pressure in the internal air duct becomes greater, then the mixed flow fan will do more work in a centrifugal mode, such that the fan supplies the air radially and directly from the lower air port next to the fan, resulting in internal air suction, and as a result, a reverse operation mode is realized.
  • the air enters from the upper air port, passes through the evaporator from the surrounding to the middle, and enters the air duct from the middle position of the water pan.
  • the air is supplied to the lower air port under the driven of the fan, so as to realize the purpose of lower air supply.
  • a method for controlling an air conditioner cabinet is provided.
  • the method is used for controlling the above-mentioned air conditioner cabinet, and the method includes the following steps: when a heating mode is selected by a controller of the air conditioner cabinet, the regulating mechanism 40 is located at the necking position, the mixed flow fan 30 sucks the external airflow into the housing 10 from the upper air port 11, so as to perform heat exchange with the heat exchanger 20, and then discharges the external airflow from the housing 10 through the lower air port 12; and when a refrigeration mode is selected by the controller, the regulating mechanism 40 is located at the flaring position, the mixed flow fan 30 sucks the external airflow into the housing 10 from the lower air port 12, so as to perform heat exchange with the heat exchanger 20, and then discharges the external airflow from the housing 10 through the upper air port 11.
  • the air conditioner cabinet further includes an air supply mode, when the air supply mode is selected by the controller, the regulating mechanism 40 is located at the necking position, the mixed flow fan 30 sucks the external airflow into the housing 10 from the upper air port 11, and then discharges the external airflow from the housing 10 through the lower air port 12, or, when the air supply mode is selected by the controller, the regulating mechanism 40 is located at the flaring position, the mixed flow fan 30 sucks the external airflow into the housing 10 from the lower air port 12, and then discharges the external airflow from the housing 10 through the upper air port 11, and the heat exchanger 20 is in a non-working state in the air supply mode, that is, the heat exchanger does not perform heat exchange work.
  • spatially relative terms can be used here, for example, “on”, “above”, “on the surface of”, “on the top” and the like are used for describing the spatial positional relationship between one device or feature and other devices or features shown in the figure. It should be understood that, the spatially relative terms are intended to encompass different orientations in use or operation other than the orientation of the device described in the figure. For example, if the device in the figure is inverted, then it is described as “above other devices or structures", or the device “above other devices or structures” will be positioned as “below other devices or structures” or “under other devices or structures”. Thus, the exemplary term “above” can include two orientations of “above” and “below”. The device can also be positioned in other different ways (rotated by 90 degrees or in other orientations), and the spatially relative description used here is explained accordingly.
