controlling to close the first air door assembly 521, separating the second air inlet 61 from the first air outlet 52, and opening the second air door assembly 631, so as to form an air inlet passage for air to sequentially pass through the third air inlet 63 and the second air outlet 62;
and entering an air supply mode.
In this embodiment, after the air conditioner receives the instruction of entering the air supply mode, the compressor 2 and the condenser fan are turned off, the evaporator fan 42 is turned on, and the first air door 5212 is controlled to be closed by the first driving mechanism 5211, at this time, the evaporator 41 has no heat exchange function and only has ventilation function, in order to increase the air intake, the second air door 6312 is controlled to be opened by the second driving mechanism 6311, the air directly enters the third air inlet 63 from the outside through the second air door 6312, and enters the evaporator end air inlet cavity 7 through the second air outlet 62, thereby increasing the air intake, and the air inlet passage in the air supply mode is as shown in fig. 11. It should be noted that, in the present mode, air does not need to pass through the evaporator 41, and enters the second air intake assembly 6 from the outside through the second air door 6312, and then enters the evaporator fan 42, and this air intake passage has small air intake resistance, large air volume and low noise. If the third air inlet 63 is not provided, air will pass through the evaporator 41 and then enter the evaporator fan 42, so that the air volume is reduced, and the air inlet resistance is high. The state diagram of each component of the three modes is shown in fig. 12.
From the state of the components of the above three modes, it can be seen that the compressor 2 operates only in the cooling mode. In the fresh air mode and the air supply mode, the compressor 2 is turned off. The purpose of the compressor 2 being turned off is to prevent that in fresh air mode, air will pass through the first air intake assembly 5, and the first air intake assembly 5 is connected to the condenser assembly 3, and air will exchange heat through the condenser assembly 3, and if the compressor 2 is turned on, air will be heated and then re-enter the evaporator assembly 4 for cooling down again, which will result in energy waste. Also, in the air supply mode, if the compressor 2 is turned on, the air of the evaporator assembly 4 mainly originates from the air supply mode air inlet 73, the air passing through the evaporator assembly 4 is greatly reduced, and the heat exchange efficiency is low, which also causes energy waste.
The control method further comprises the following steps:
acquiring the concentration of carbon dioxide;
comparing the current concentration of the carbon dioxide with a concentration preset value;
and if the current concentration of the carbon dioxide is larger than the concentration preset value, sending out an instruction for entering a fresh air mode or keeping the fresh air mode.
In this embodiment, the air conditioner has a cooling mode, a fresh air mode and an air supply mode, and the following three control methods for switching modes are set according to the comfort and health requirements of the air conditioner in a small space: setting different concentration preset values for different modes, and acquiring the carbon dioxide concentration by using a carbon dioxide concentration sensor, wherein the concentration preset value is preset to be m1 for a refrigeration mode or an air supply mode, and if the current carbon dioxide concentration is greater than m1, entering a fresh air mode; and (3) for the fresh air mode, presetting a concentration preset value as m2, avoiding frequent mode switching, taking m1 to be more than m2, if the current carbon dioxide concentration is more than m2, maintaining the fresh air mode, and identifying the carbon dioxide concentration again every t1 time, and judging whether to switch modes.
The control method further comprises the following steps:
if the current concentration of the carbon dioxide is smaller than or equal to the concentration preset value, acquiring the current temperature;
comparing the current temperature with a temperature preset value;
if the current temperature is smaller than the temperature preset value, an instruction for entering an air supply mode or an instruction for stopping is sent out;
and if the current temperature is greater than the temperature preset value, sending out an instruction for entering a refrigeration mode.
In this embodiment, if the current carbon dioxide concentration is less than or equal to the concentration preset value (i.e. m1 and m 2), the temperature sensor is used to obtain the current temperature, and different temperature preset values are set for different modes as well, for example, for an air supply mode or a shutdown, the preset temperature value is set to be T1 in advance, if the current temperature is less than T1, the air supply mode or the shutdown can be operated according to user definition, and the carbon dioxide concentration and the temperature are redetected at intervals of T2, and if the current temperature is greater than T1, the refrigeration mode is operated, and the carbon dioxide concentration is redetected at intervals of T3; for the fresh air or refrigeration mode, a preset temperature value is set as T0 in advance, in order to avoid frequent switching modes, T1 is taken to be more than T0, if the current temperature is less than T0, the air supply mode can be switched to or stopped according to user definition, the carbon dioxide concentration and the temperature are also re-detected at intervals of T2, if the current temperature is greater than T0, the refrigeration mode is operated, and the carbon dioxide concentration is also re-detected at intervals of T3. A flow chart of the automatic switching of the three modes is shown in fig. 13.
The time t1, t2, t3 mentioned above may be identical or inconsistent, and may be specifically set according to specific requirements.
