Example Embodiment

[0071] like Figure 1-2 As shown, the present invention provides a control method for a multi-line system, wherein:

[0072] The multi-line system includes: at least two of the indoor unit 6, the floor heating module 9 and the hot water module 8;

[0073] The control method includes:

[0074] The detection step is used to detect the working parameters of each module in the indoor unit 6, the floor heating module 9 and the hot water module 8; the working parameters here include the actual high pressure saturation temperature β of the refrigerant in the multi-line system, Total demand capacity Q of indoor unit 6 n需 , detect the total demand capacity Q of the floor heating module 9 d需 and the total demand capacity Q of the hot water module 8s需 and so on; each module here is an existing module, for example, if there are only indoor units and floor heating modules, these two modules are detected, if there are only floor heating modules and hot water modules, these two modules ar...

Abstract

The present disclosure provides a control method of a multi-connection system, a multi-connection system and a storage medium. The control method includes: a detection step of detecting working parameters of each module in an indoor unit, a floor heating module and a hot water module; a judgment step of judging the indoor unit , Whether there are at least two modules in the floor heating module and the hot water module running; the control step is to set the priority order of at least two of the indoor unit, the floor heating module and the hot water module, and the priority order is according to the needs of different modules. The high-pressure saturation temperature of the refrigerant is determined, and the module with the lowest required high-pressure saturation temperature is the highest priority, and at least two of the indoor unit, the floor heating module and the hot water module are controlled to operate according to the detected parameters and priority order. According to the present disclosure, the capability allocation and priority when multiple functions are running at the same time are reasonably controlled, the problems of system control conflict and instability when multiple functions are running at the same time are solved, the usage scenarios of the product are broadened, and the user's comfort is improved.

Description

[0001] The present invention claims the priority of the Chinese patent application with the application number 202110308331.1 and the title of the invention "a control method for a multi-connected air-conditioning system" submitted to the Chinese Patent Office on March 23, 2021, the entire contents of which are incorporated herein by reference Applying. technical field [0002] The invention relates to the technical field of multi-connection, in particular to a control method of a multi-connection system, a multi-connection system and a storage medium. Background technique [0003] Multi-connectors are now more and more widely used in homes, which involves the needs of other heat exchange functions in many homes. In addition to the air-conditioning functions provided by traditional multi-connectors, it also involves domestic hot water, floor heating and other functional requirements. [0004] Because the multi-function multi-connection in the prior art cannot perform priorit...
