Embodiment 1

[0030] In the preferred embodiment 1 of the present invention, a load-based air-conditioning control method is provided. This control method can be directly applied to various air conditioners, and can also be applied to other devices with partial air-conditioning functions. It can be realized by installing software, APP on the air conditioner or other devices, or writing the corresponding program of the controller. Specifically, figure 1 An alternative flowchart showing the method, such as figure 1 As shown, the method includes the following steps S102-S106:

[0031] S102: Detect whether the load in the air-conditioning area changes;

[0032] S104: When the load changes, determine the frequency adjustment amount of the compressor according to the load change;

[0033] S106: Adjust the frequency of the compressor according to the frequency adjustment amount.

[0034] In the above embodiments, a load-based air-conditioning control scheme is provided. By detecting whether th...

Embodiment 2

[0070] Based on the load-based air-conditioning control method provided in the above-mentioned embodiment 1, a load-based air-conditioning control device is also provided in preferred embodiment 2 of the present invention, specifically, Figure 7 shows an optional structural block diagram of the device, such as Figure 7 As shown, the device includes:

[0071] A detection module 702, configured to detect whether the load in the air-conditioning area changes;

[0072] The determination module 704 is connected with the detection module 602, and is used to determine the frequency adjustment amount of the compressor according to the load change when the load changes;

[0073] The adjustment module 706 is connected with the determination module 604 and is used for adjusting the frequency of the compressor according to the frequency adjustment amount.

Abstract

The invention discloses an air conditioner control method and device and an air conditioner system based on loads. The air conditioner control method comprises the steps that whether the loads of theoperating zone of an air conditioner are changed or not is detected; when the loads are changed, the frequency regulating variable of a compressor is determined according to change of the loads; and the frequency of the compressor is regulated according to the frequency regulating variable. The problem that in the prior art, temperature regulating of the air conditioner is hysteretic is solved, the frequency of the compressor is quickly regulated, and the temperature of the interior of the operating zone of the air conditioner keeps durable and stable.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a load-based air conditioner control method, a control device and an air conditioner. Background technique [0002] At present, the temperature control methods of most inverter air conditioners use PID algorithm or fuzzy control algorithm to adjust the compressor frequency and then adjust the temperature according to the difference between the indoor temperature and the set temperature. There is a disadvantage in such a control method - the temperature regulation is too lagging. Because this method needs to wait until the reference temperature (maybe the temperature where the thermostat is located or the temperature at the return air) reaches a certain difference with the set temperature, and the air conditioner starts to adjust the compression after the difference is fed back to the air conditioner. The frequency of the compressor, and the air conditioner can o...
