Problems solved by technology

[0003] The existing air conditioner installation can only be controlled by manual operation, and the air conditioner does not have the ability to judge whether it is connected incorrectly. Running the air conditioner when the connection between the outdoor unit and the indoor unit is wrong will affect the system reliability of the air conditioner and the user's use effect

Embodiment 1

[0050] Such as figure 1 As shown, an embodiment of the present invention provides a control method for an air-conditioning system. The air-conditioning system includes an outdoor unit and a plurality of indoor units. The outdoor unit and the indoor unit are connected through a communication line. The control method includes:

[0051] Step 102: Obtain the coil temperature of the heat exchanger of the indoor unit and the indoor ambient temperature;

[0052] Step 104: Determine whether the communication connection between the outdoor unit and the indoor unit is abnormal according to the current operating state of the air conditioning system, the coil temperature, and the indoor ambient temperature;

[0053] Step 106: Control the indoor unit to issue a prompt message based on the abnormal communication connection between the outdoor unit and the indoor unit.

[0054] The control method of the air-conditioning system provided by the present invention judges whether the communicati...

Embodiment 2

[0061] Such as figure 2 As shown, an embodiment of the present invention provides a control method for an air-conditioning system. The air-conditioning system includes an outdoor unit and a plurality of indoor units. The outdoor unit and the indoor unit are connected through a communication line. The control method includes:

[0062] Step 202: Obtain the coil temperature of the heat exchanger of the indoor unit and the indoor ambient temperature;

[0063] Step 204: Based on the current operating state of the air conditioning system being the heating mode, compare the difference between the coil temperature and the indoor ambient temperature with a preset threshold;

[0064] Step 206: Based on the fact that the difference is greater than the preset threshold, the communication connection between the outdoor unit and the indoor unit is normal;

[0065] Step 208: Based on the fact that the difference is less than or equal to the preset threshold, the communication connection be...

Embodiment 3

[0069] Such as image 3 As shown, an embodiment of the present invention provides a control method for an air-conditioning system. The air-conditioning system includes an outdoor unit and a plurality of indoor units. The outdoor unit and the indoor unit are connected through a communication line. The control method includes:

[0070] Step 302: Obtain the coil temperature of the heat exchanger of the indoor unit and the indoor ambient temperature;

[0071] Step 304: Based on the fact that the current operating state of the air conditioning system is the cooling mode and the indoor unit is in the power-on state, compare the difference between the indoor ambient temperature and the coil temperature with a preset threshold;

[0072] Step 306: Based on the fact that the difference is greater than the preset threshold, the communication connection between the outdoor unit and the indoor unit is normal;

[0073] Step 308: Based on the fact that the difference is less than or equal t...

Abstract

The invention provides a control method of an air conditioning system, the air conditioning system and a computer storage medium. The air conditioning system comprises an outdoor unit and a pluralityof indoor units, wherein the outdoor unit is in communication connection with the indoor units through communication lines. The control method comprises the following steps that the coil pipe temperature of a heat exchanger of each indoor unit and the indoor environment temperature are obtained; according to the current operation state of the air conditioning system, whether the communication connection between the outdoor unit and the indoor units is abnormal or not is determined; and under the condition that the communication connection between the outdoor unit and the indoor units is abnormal, the indoor units are controlled to send out prompt information. According to the control method of the air conditioning system, in the installation process of the air conditioning system, under the condition that the communication connection is wrong, a prompt can be sent out, so that the communication connection between the outdoor unit and the indoor units can be conveniently corrected in time, and accurate installation of an air conditioner is ensured; and in the use process of the air conditioner, the air conditioning system can be prevented from running under the condition that the communication connection between the outdoor unit and the indoor units is wrong as much as possible, and the service life of the indoor units and the service life of the outdoor unit are prolonged.

Description

technical field [0001] The present invention relates to the technical field of air-conditioning equipment, and in particular, relates to a method for controlling an air-conditioning system, an air-conditioning system, and a computer storage medium. Background technique [0002] The indoor units of the multi-split air-conditioning system are mainly installed indoors in large buildings for office, living, and activity needs, and the outdoor units are mainly installed on the ground, roof or mezzanine of the building. During the installation process of the air conditioning system, it is necessary to maintain a one-to-one correspondence between the system piping and communication of the outdoor unit and the indoor unit, so as to ensure the normal operation of the system and provide reliable services for users. [0003] The existing air conditioner installation can only be controlled by manual operation, and the air conditioner does not have the ability to judge whether it is conn...
