Embodiment 1

[0038] like figure 1 As shown, the frequency control method according to the embodiment of the present invention is used to adjust the operating frequency of the compressors of the one-to-many air conditioner, and specifically includes the following process steps:

[0039] Step 10, when the one-drag multi-air conditioner is turned on for heating and running, acquire the capacity requirement identification value, set temperature, and indoor ambient temperature corresponding to each indoor unit among all indoor units currently in operation at preset time intervals , to determine the initial operating frequency of the compressor within each preset time.

[0040] It can be understood that the preset time can be any suitable value, and it is sufficient to meet the correction requirements for the operating frequency of the compressors of the one-driver-multiple air conditioner. Preferably, the preset time can be taken as 50s, that is, every 50s for The operating frequency of the co...

Embodiment 2

[0116] like Figure 4 As shown, the frequency control device 40 according to the embodiment of the present invention is used to adjust the operating frequency of the compressors of a one-to-many air conditioner, and the frequency control device 40 includes: a first processing module 402, a second processing module 404, a determination Module 406 and Modification Module 408 .

[0117]Wherein, the first processing module 402 is used to obtain the capacity demand identification value corresponding to each indoor unit in all indoor units currently in the operating state at preset time intervals when the one-drag multi-air conditioner is turned on and running for heating , set temperature and indoor ambient temperature, to determine the initial operating frequency of the compressor within each preset time; the second processing module 404 is used to obtain the outdoor Ambient temperature; the determining module 406 is used to determine the target frequency correction coefficient w...

Embodiment 3

[0129] like Figure 5 As shown, the one-to-multiple air conditioner according to the embodiment of the present invention includes a memory 502, a processor 504, and a frequency control program stored in the memory 502 and operable on the processor 504, and the processor 504 executes the frequency control program. When controlling the program, the frequency control method as described in the first embodiment above is realized.

[0130] Preferably, the one-to-multiple air conditioner is a frequency conversion one-to-multiple air conditioner.

Abstract

The invention discloses a frequency control method, a frequency control device, a multi-split air conditioner and a storage medium. The frequency control method comprises the following steps that whenthe multi-split air conditioner is in the heating operation, a capability requirement identification value corresponding to each indoor unit in all indoor units in the running state, set temperatureand indoor environment temperature are acquired at interval preset time so as to determine the initial operating frequency of a compressor in each preset time; in each preset time, outdoor environmenttemperature is acquired; a target frequency correction coefficient within each preset time is determined according to the outdoor environment temperature; and the initial operation frequency within each preset time is corrected according to the target frequency correction coefficient so as to determine the target operating frequency of the compressor. According to the frequency control method, the frequency control device, the multi-split air conditioner and the storage medium, the problems that the accuracy of the tube temperature correction frequency of the middle of the indoor unit is lowand the needed time is too long are solved, and the effect of improving the heating capacity of the multi-split air conditioner is achieved.

Description

technical field [0001] The present invention relates to the technical field of household electrical appliances, in particular to a frequency control method, a frequency control device, a one-drag multi-air conditioner and a computer-readable storage medium. Background technique [0002] At present, when the heat pump type one-to-multiple air conditioner operates in the heating mode, the initial target frequency is generally calculated according to the weighted demand of the indoor unit. Any form of frequency limitation is valid. [0003] However, the inventors of the present application have found that the above-mentioned technology has at least the following technical problems: [0004] Technical problem 1: When the connected indoor units are fully turned on, the initial target frequency obtained by the weighting algorithm is often too low to meet the heating demand of turning on the indoor units. [0005] Technical problem 2: According to the scheme of correcting the ope...
