Prompt method, prompt system and multi-connected air-conditioning system for multi-connected small-load operation

Abstract

The invention belongs to the air conditioner technology, and provides a prompting method and system of multi-online small load running. The method comprises the following steps that system parameters of an air conditioner system under the small load running state are preset; running data of a communicative refrigerant system are periodically collected; whether the collected running data meet the judgment condition of the small load running state of the air conditioner system or not is judged; if yes, prompting information including the address number of an indoor unit in small load running is sent out; if not, the step of periodically collecting the running data of the communicative refrigerant system is executed again. The prompting information that the system is in small load running can be sent out by setting the condition for judging whether the multi-online system is in small load running or not and judging whether the indoor unit meeting the condition meets the number of times of actual application situations, a request or the indoor unit in small load running can be clearly prompted, , the user experience of the multi-online air conditioner is improved, and it can be indicated that which one or which several of indoor units are in small load running.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a prompting method, a prompting system and a multi-connected air-conditioning system for multi-connected and small-load operation. Background technique [0002] At present, in commercial places such as apartment hotels or SOHO (Small Office Home Office) office buildings, multi-connected network centralized control systems are widely used, and often need to use the power division function to count the power consumption of different rooms or areas. Often, several indoor units in a refrigerant system share one or more outdoor units. If one or a few indoor units are turned on for a long time, while the other units are turned off, the refrigerant system will be in the long-term position of a large horse-drawn cart. The low-load operation state will lead to a relatively large power consumption of the turned-on internal unit, which will have a certain impact on the ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a prompt method for the operation of multi-connected units with a small load, aiming to solve the problem that if the capacity request in the traditional refrigerant system is lower than a certain threshold value, it cannot indicate which or which indoor units are operating under a small load. The problem
