Embodiment 1

[0024] According to an embodiment of the present invention, an embodiment of a compressor frequency control method is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0025] figure 1 is a flow chart of a compressor frequency control method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0026] Step S102, acquiring the change rate of the water temperature in the water system of the air conditioning unit.

[0027] Specifically, in the above-mentioned steps, the above-mentioned air-conditioning unit can be a household central air-conditioning unit that centrally processes the indoor air-conditi...

Embodiment 2

[0083] According to an embodiment of the present invention, an embodiment of a compressor frequency control device is also provided.

[0084] Figure 8 It is a structural schematic diagram of a compressor frequency control device according to an embodiment of the present invention, as shown in Figure 8 As shown, the device includes: an acquisition module 801 , a determination module 803 and an adjustment module 805 . Among them, the obtaining module 801 is used to obtain the change rate of the water temperature in the water system of the air-conditioning unit; and the determination module 803 is used to determine the value range to which the change rate belongs according to the change rate; the adjustment module 805 is used to adjust according to the value range The frequency conversion mode of the compressor in the air conditioning unit.

Abstract

The invention discloses a control method and device for the frequency of a compressor. The control method comprises the steps that the change rate of the water temperature in a water system in an air conditioner unit is obtained; the value range of the change rate is determined according to the change rate; and the frequency conversion mode of the compressor in the air conditioner unit is adjusted according to the value range. According to the control method and device for the frequency of the compressor, the technical problem that the user experience effect is poor due to the fact that the water system capacity is different, frequent shutdown is caused, or the target temperature reaching time is prolonged in an existing frequency conversion household type air conditioner system is solved.

Description

technical field [0001] The invention relates to the field of home appliance control, in particular to a method and device for controlling the frequency of a compressor. Background technique [0002] In recent years, the central and northern regions of my country consume a large amount of primary energy (such as coal) for heating every year. The use of primary energy has continuously deteriorated the global environment, such as smog and sandstorms. In order to meet the needs of heating in winter and cooling in summer without damaging the environment, "coal to electricity" has become an effective measure to prevent and control environmental pollution due to its low difficulty in implementation and quick results. In the "coal to electricity" project Driven by the drive, household central air-conditioning units (also known as household central air-conditioning or household central air-conditioning) came into being. The household central air-conditioning unit uses the water syst...
