Wherein, fresh air inlet 3 is used for communicating with the one end of fresh air pipe 9, and the other end of fresh air pipe 9 is used for communicating with outdoor environment.
Wherein, this embodiment is when starting first heat transfer wind and send device 5, and first heat transfer wind send device 5 to be used for drawing wind from indoor air intake 2 to cool or heat the processing to the air of indoor (the effect space of air conditioner), the air after the processing is arranged to indoor through air outlet 4.
Correspondingly, when the second heat exchange air supply device 6 is started, the second heat exchange air supply device 6 is used for sucking air from the fresh air inlet 3 so as to refrigerate or heat outdoor fresh air, and the processed air is discharged to the indoor through the air outlet 4. So, send device 6 to the heat transfer of outdoor new trend and send the processing with wind based on the second heat transfer, both can ensure to input to the temperature of indoor new trend, can reduce the carbon dioxide concentration of indoor environment again effectively, promoted user experience.
As shown in fig. 2, the first heat-exchange air-sending device 5 shown in this embodiment includes a first heat exchanger 51, a first fan 52 and a first air duct 53; a first side surface of the first heat exchanger 51 faces the indoor air inlet 2, a second side surface of the first heat exchanger 51 faces a first port of the first air duct 53, and a second port of the first air duct 53 is communicated with the air outlet 4; the first fan 52 is arranged in the first air duct 53; the second heat exchange air supply device 6 comprises a second heat exchanger 61, a second fan 62 and a second air duct 63; a first side surface of the second heat exchanger 61 faces the fresh air inlet 3, a second side surface of the second heat exchanger 61 faces a first port of the second air duct 63, and a second port of the second air duct 63 is communicated with the air outlet 4; the second fan 62 is disposed in the second air duct 63.
Further, in the embodiment, at least one of the first fan 52 and the second fan 62 is a centrifugal fan; in the case where the first fan 52 is a centrifugal fan, the first air duct 53 is formed in a volute shape; in the case where the second fan 62 is a centrifugal fan, the second air duct 63 is formed in a volute shape.
In order to improve the air supply efficiency and reduce the occupied space inside the air conditioner, the first fan 52 and the second fan 62 shown in this embodiment are preferably centrifugal fans. In the case that the first fan 52 and the second fan 62 are designed as centrifugal fans, the first air duct 53 and the second air duct 63 are designed as volute correspondingly.
Meanwhile, the first fan 52 and the second fan 62 shown in this embodiment can be started to operate when a certain current is input. Since the first heat exchanger 51 and the second heat exchanger 61 shown in this embodiment are respectively communicated with the condenser of the outdoor unit of the air conditioner through the refrigerant pipelines, the control valves on the corresponding connecting pipelines of the first heat exchanger 51 and the second heat exchanger 61 can be controlled to open, so as to start the cooling or heating operation of the first heat exchanger 51 and the second heat exchanger 61.
Preferably, in order to realize fresh air supply control to the indoor environment, the method for determining the opening states of the first heat exchange air supply device and the second heat exchange air supply device according to the carbon dioxide concentration includes, but is not limited to, the following steps:
and under the condition that the concentration of the carbon dioxide is within the range of the safety threshold, controlling to open the first heat exchange air conveying device and close the second heat exchange air conveying device. So, this embodiment is in the safety threshold value within range at carbon dioxide concentration, and the first heat transfer air supply device of accessible refrigerates or heats the processing to indoor environment normally, and at this moment, because carbon dioxide concentration accords with house personnel's normal life requirement, need not to open second heat transfer air supply device.
Correspondingly, under the condition that the concentration of the carbon dioxide is higher than the maximum value of the safety threshold range, the second heat exchange air conveying device is controlled to be started, and the first heat exchange air conveying device is controlled to be closed. At this moment, because carbon dioxide concentration is too high, probably influence house personnel's normal life requirement, at this moment, can open second heat transfer air supply unit alone to carry the new trend after the heat exchange treatment to indoor, both can ensure to input the temperature to indoor new trend, can reduce indoor environment's carbon dioxide concentration again effectively, promoted user experience.
The safe threshold range of the carbon dioxide concentration shown in this embodiment may be set to 0.01% -0.4% according to the adaptability of the human body to the carbon dioxide concentration.
Further, in the case that the concentration of carbon dioxide is higher than the maximum value of the safety threshold range, the control of opening the second heat exchange air-sending device further includes:
determining the target wind speed of the second heat exchange air conveying device for air conveying according to the concentration of the carbon dioxide; and controlling the second heat exchange air conveying device according to the target air speed.
Specifically, when the carbon dioxide concentration is too high, in order to reduce the carbon dioxide concentration in the room as soon as possible, the present embodiment may set the target wind speed to be the high wind speed, and control the second fan of the second heat exchange air supply device to operate at the high wind speed, so as to increase the amount of wind for supplying fresh air to the room.
At relatively low carbon dioxide concentrations, for example: the concentration of carbon dioxide is close to the minimum value of the safe threshold range, the target wind speed can be set to be the low wind speed in the embodiment, and the second fan of the second heat exchange air supply device is controlled to operate at the low wind speed so as to reduce the air volume of the fresh air supplied to the room.
Preferably, the fresh air control method of the air conditioner in this embodiment further includes: and under the condition that the temperature difference value between the ambient temperature and the set temperature is greater than a preset value, controlling to simultaneously start the first heat exchange air conveying device and the second heat exchange air conveying device.
