Description of drawings

In order to make the purpose, technical solutions and advantages of the present invention more clear, the method for controlling the running time of the air conditioner of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments; it should be understood that the specific embodiments described here are only used for The present invention is explained, not intended to limit the present invention.

Fig. 1 is the air-conditioning system operating flowchart of the specific embodiment of the control method of air-conditioning running time of the present invention;

detailed description

The present invention sets the running time of a single unit, multiple units or units in a group through the centralized controller in the air conditioning system, so that when the running time reaches the set value, the air conditioner is turned off. The running time can be set freely: it can be set individually for different air conditioners, or it can be set specifically for certain sets and combined freely.

A method for controlling the running time of an air conditioner in this embodiment is used to automatically shut down the internal unit of the air conditioner in the air conditioner system after running for a period of time, including the following steps:

S1. Initially setting the limited time for the operation of the air-conditioning internal unit in the air-conditioning system;

S2. The air conditioner internal unit runs automatically in a fixed cycle according to the limited time, and automatically shuts down after running for the limited time in each cycle;

Wherein step S1 specifically comprises the following steps:

S1-1. First, connect the air conditioning system to the working state, and the centralized controller in the air conditioning system controls the air conditioner internal unit to apply for the serial number in the air conditioning system from the air conditioner external unit; when the air conditioner internal unit obtains the address After numbering, it will enter the normal operating state; preferably, all air-conditioning internal units in the air-conditioning system are provided with address chips that can be set to be uniquely addressed globally, and apply to the air-conditioning external units by means of communication. The number in the air conditioning system; the air conditioner internal unit enters the normal operation state after obtaining its number in the air conditioning system.

S1-2. The air-conditioning external units in the air-conditioning system collect the serial number values of all air-conditioning internal units in the air-conditioning system, and the centralized controller reads the serial number values of the air-conditioning internal units through the air-conditioning external units, and It is displayed on its user interface; the centralized controller in the air-conditioning system can control less than or equal to 256 air-conditioning internal units.

S1-3. According to the number of the air-conditioning internal unit displayed on the user interface of the centralized controller, the user sets time-limiting parameters for the air-conditioning internal units in the air-conditioning system that need to set a limited time; preferably, The content of the time-limited parameters includes: grouping or centralized setting of all air-conditioning internal units in the air-conditioning system, and setting the running time or the fixed time point of automatic shutdown for the air-conditioning internal units or units respectively.

S1-4. The centralized controller automatically sends the set time-limited parameters to the air-conditioning internal units in the air-conditioning system that need to set a limited time. For example, the centralized controller can first send the time-limited parameters to the air conditioner The external unit and the air conditioner external unit send the corresponding air conditioner internal unit according to the received information.

Preferably, the air-conditioning internal units that need to be set for a limited time as described in S1-4 include one air-conditioning internal unit in the air-conditioning system, or multiple air-conditioning internal units, or air-conditioning units in the air-conditioning system One or more units composed of indoor units; for example: when it is necessary to set the air conditioner indoor units numbered No. 1, No. 128, and No. 256, first divide these inner unit numbers into a group, and then perform unified setting and operation Time limit function, when there are few indoor units that need to be set, it can be set individually for each unit without grouping. For example, if you need to set all indoor units from No. 1 to No. 256, you only need to divide all indoor units into one group for setting, which is easy and convenient to operate.

Further, the number of the air-conditioning internal unit in the air-conditioning system is the original number of the air-conditioning internal unit in the unit; since the air-conditioning internal address chip, so the number in the air-conditioning system can effectively distinguish different air-conditioning internal units at any time.

Preferably, the limited time in step S1 is a fixed time point for automatic shutdown of the air conditioner internal unit, or the running time of the air conditioner internal unit. Further, the fixed period in the step S2 is 24 hours, and the fixed period is calculated in a manner of clearing at zero time. Furthermore, the limited time is counted from the first start-up operation of the air conditioner internal unit after zero o'clock, and accumulated within 24 hours;

That is, after 12 o'clock in the evening every day, the running time will be reset to zero, and the time will be calculated from the first start-up of the air conditioner on the same day. , when the total amount reaches the limited running time, it will be forced to shut down;

At the same time, it can also be set to force shutdown when the time runs to a fixed time point; for example, in a certain enterprise, the fixed time for automatic shutdown of the air conditioner internal unit is set at 1 hour after get off work, and once the air conditioner internal unit runs to At the time point of 1 hour after get off work, it will automatically shut down, so that if you forget to turn off the air conditioner after get off work, the air conditioner can be automatically turned off to achieve the purpose of saving energy.

As shown in FIG. 1 , it is a schematic diagram of the operation flow of the method for controlling the running time of the air conditioner in this embodiment.

Finally, it should be noted that it is obvious that those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and equivalent technologies thereof, the present invention also intends to include these modifications and variations.
