Place is respectively equipped with temperature detection part 8.
Optionally, temperature detection part 8 is multiple, and multiple temperature detection parts 8 detect that the average value of temperature is inlet air temperature,
The inlet air temperature detected in this way is more accurate.
In some embodiments, when the temperature difference be more than the first preset temperature when, incoming air area control piece 7 completely close second into
Air port 102;When the temperature difference is less than or equal to the first preset temperature, incoming air area control piece 7 opens the second air inlet 102.In the reality
It applies in example, when the temperature difference between inlet air temperature and setting temperature is larger, thoroughly closes at the second air inlet 102 and no longer enter the wind,
Ensure that the wind of the blowout of ceiling machine 100 is all the air after heat exchange, indoor people can be allowed obviously to experience sendible temperature in this way
Variation.Optionally, the first preset temperature is more than 9 degree, and still optionally further, the first preset temperature is 10 degree.
In some embodiments, when the temperature difference be less than or equal to the first preset temperature and more than the second preset temperature when, second into
It is entered the wind with the first preset area in air port 102;When the temperature difference is less than or equal to the second preset temperature, the second air inlet 102 is pre- with second
If area is entered the wind, the first preset area is less than the second preset area.It is different that the second air inlet 102 is controlled by the different temperature difference
Incoming air area, to which 102 incoming air area of the second air inlet is at least there are two adjust automatically shelves, control is more accurate.
Specifically, the first preset temperature is more than the second preset temperature.Optionally, the first preset temperature is more than 9 degree, further
Optionally, the first preset temperature is 10 degree.Optionally, the second preset temperature is less than 6 degree, still optionally further, the second default temperature
Degree is 4 degree.
Specifically, the second preset area is less than or equal to the maximum incoming air area of the second air inlet 102.Optionally, first is pre-
If area is less than or equal to the 1/2 of the maximum incoming air area of the second air inlet 102, still optionally further, the first preset area is equal to
The 1/3 of the maximum incoming air area of second air inlet 102.Optionally, the second preset area is the maximum air inlet of the second air inlet 102
The 80%-100% of area.
In a specific embodiment, after the booting of ceiling machine 100, when detecting that the temperature difference is more than the first preset temperature,
Second air inlet 102 completely closes;When detecting that the temperature difference is less than or equal to the first preset temperature, the second air inlet 102 is opened simultaneously
It is entered the wind with the first preset area;
After the second air inlet 102 is initially opened and continues the first preset time, if the temperature difference is more than the second preset temperature,
Second air inlet 102 keeps entering the wind with the first preset area, if the temperature difference is less than or equal to the second preset temperature, the second air inlet
102 adjust to the second preset area air inlet.
That is, between detecting twice, certain interval of time (i.e. the first preset time) is filled to ceiling machine 100 in this way
