Further, because establish the replacement heat piece in the new trend pipeline in this embodiment, can make the new trend through in the indoor machine of rethread behind the heat transfer piece heat transfer, reduce indoor outer difference in temperature to it is undulant to reduce indoor temperature, improves user's comfort level.

In an embodiment of the present invention, a control method of an air conditioner includes the steps of: acquiring the carbon dioxide concentration of the indoor environment; the rotating speed of the indoor fan and the operation parameters of the driving piece are adjusted according to the concentration of the carbon dioxide, so that the air inlet amount of the fresh air pipeline is adjusted, the larger the concentration of the carbon dioxide is, the larger the air inlet amount of the fresh air pipeline is, the fresh air of the fresh air pipeline is extracted through the indoor fan arranged in the indoor unit, an additional fresh air fan is not needed, and the cost can be saved.

Further, referring to fig. 3, a second embodiment of the present invention is proposed based on the first embodiment, and in this embodiment, the method for controlling an air conditioner further includes:

s30, the air conditioner runs for a first preset time in a refrigeration mode, and a drain valve is opened;

and S40, closing the drain valve after the drain valve is opened for a second preset time.

In one embodiment, a water outlet of the heat exchange member is provided with a drain valve. After the air conditioner runs for a first preset time in the refrigeration mode, the drain valve is opened so as to discharge the condensed water generated after the refrigeration mode is run to the outdoor environment through the drain pipe and the fresh air inlet of the fresh air pipeline. The first preset time is used for confirming the amount of condensed water generated by the air conditioner in the cooling mode, for example, when the first preset time reaches 30min, the amount of condensed water is large, and at this time, the drain valve can be opened to drain the condensed water.

And further, after the drain valve is opened for a second preset time, closing the drain valve. And the second preset time is used for confirming whether the condensed water is completely discharged.

Like this, this embodiment is through setting up the drain valve in order can in time to discharge the comdenstion water that the air conditioner operation refrigeration mode produced outdoor to guarantee the normal operating of air conditioner.

The invention further provides a control device of an air conditioner, which comprises a memory, a processor and a control program of the air conditioner, wherein the control program of the air conditioner is stored on the memory and can run on the processor, and when being executed by the processor, the control device of the air conditioner realizes the steps of the control method of the air conditioner according to any one of the above embodiments.

The present invention also proposes a readable storage medium having stored thereon a control program of an air conditioner, which when executed by a processor implements the steps of the control method of the air conditioner according to any one of the above embodiments.

The above-mentioned serial numbers of the embodiments of the present invention are merely for description and do not represent the merits of the embodiments.

Through the above description of the embodiments, those skilled in the art will clearly understand that the method of the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but in many cases, the former is a better implementation manner. Based on such understanding, the technical solutions of the present invention may be substantially or partially embodied in the form of a software product, where the computer software product is stored in a storage medium (e.g., ROM/RAM, magnetic disk, optical disk), and includes instructions for enabling a terminal device (e.g., a mobile phone, a computer, a cloud server, an air conditioner, or a network device) to execute the method according to the embodiments of the present invention.
