In present embodiment, the control of wind-guiding grate 1423 can realize as follows:
When being in refrigeration mode, the temperature difference along with indoor temperature and design temperature diminishes the direction, interflow, wind-guiding direction that controls upper and lower wind-guiding grate 1423 from forward to upward to changing to the left and right; And
When being in heating mode, along with the direction, interflow, wind-guiding direction that controls upper and lower wind-guiding grate 1423 of diminishing of the temperature difference is from down to changing to the left and right.
In the present embodiment, when being in refrigeration mode, the wind-guiding wind direction of the downward and lower wind-guiding grate 1423 in wind-guiding direction of upper wind-guiding grate 1423 is controlled upwards when the temperature difference is greater than first threshold, control the wind-guiding direction of upper and lower wind-guiding grate 1423 upwards when the temperature difference is greater than Second Threshold and is less than first threshold, control the wind-guiding direction of upper and lower wind-guiding grate 1423 when the temperature difference is less than first threshold respectively to left and right.
In other words, when the temperature difference is greater than first threshold, the direction, interflow, wind-guiding direction of upper and lower wind-guiding grate 1423 forward, this is because when the temperature difference is larger, utilizes remote air-out forward, realizes large area being lowered the temperature fast.
And when the temperature difference is greater than Second Threshold and is less than first threshold, the direction, interflow, wind-guiding direction of upper and lower wind-guiding grate 1423 upwards, this is because after rapid large-area cooling, can utilize upwards air-out to reach the object of fast cooling.
And when the temperature difference is less than Second Threshold, direction, interflow, the wind-guiding direction wind of upper and lower wind-guiding grate 1423 not to the left and right, that is to say to two Lateral supply, this is because after cooling, side feeding can improve comfort.
Experimentally, the scope of first threshold is for being more than or equal to 5 degrees Celsius, and the scope of Second Threshold is less than 5 degrees Celsius for being more than or equal to 3 degrees Celsius, can realize object above, i.e. rapid large-area cooling, fast cooling and comfort cooling.In present embodiment, first threshold is 5 degrees Celsius and Second Threshold is 3 degrees Celsius.Certainly, in other embodiments, first threshold and Second Threshold can look demand arrange, be not limited to present embodiment.
In present embodiment, when being in heating mode, the wind-guiding direction controlling upper and lower wind-guiding grate 1423 when the temperature difference is greater than the 3rd threshold value is downward, and the wind-guiding direction controlling upper wind-guiding grate 1423 when the temperature difference is less than the 3rd threshold value to the left or to the right and the wind-guiding wind direction of lower wind-guiding grate 1423 is downward.
In other words, when the temperature difference is greater than the 3rd threshold value, the direction, interflow, wind-guiding direction of upper and lower wind-guiding grate 1423 is downward, this is because when the temperature difference is larger, utilizes and sends heating installation downwards, realize being rapidly heated.
And when the temperature difference is less than the 3rd threshold value, that is to say that temperature has to a certain degree risen or has been in after in more suitable scope utilizes lower wind-guiding grate 1423 to continue to realize rapidly and efficiently heating up, and about upper wind-guiding grate, air-supply can improve comfort.
Experimentally, the scope of the 3rd threshold value, for being more than or equal to 5 degrees Celsius, can realize object above, is namely rapidly heated and comfortable intensification.In present embodiment, the 3rd threshold value is 5 degrees Celsius.Certainly, in other embodiments, the 3rd demand of can looking is arranged, and is not limited to present embodiment.
In addition, along with the power of the upper and lower axial flow blower 141 that diminishes of the described temperature difference diminishes.
In the description of this description, specific features, structure, material or feature that the description of reference term " embodiment ", " some embodiments ", " exemplary embodiment ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with described embodiment or example are contained at least one embodiment of the present utility model or example.In this manual, identical embodiment or example are not necessarily referred to the schematic representation of above-mentioned term.And the specific features of description, structure, material or feature can combine in an appropriate manner in any one or more embodiment or example.
