specific Embodiment

[0114] Figure 4 It shows a schematic flowchart of an indoor unit prompt control method in a specific embodiment of the present invention, and the multi-connected central air conditioner is in cooling mode at this time.

[0115] Such as Figure 4 As shown, the indoor unit prompt control method 400 in a specific embodiment of the present invention includes:

[0116] S402, after starting up, judge whether the continuous running time t of the current indoor unit satisfies t≥2h, if yes, go to S404, if not, repeat S402;

[0117] S404, judging whether the outdoor ambient temperature T1 satisfies 30°C≤T1≤40°C, if yes, go to S406, if not, end;

[0118] S406, judging whether the number n of all running indoor units satisfies n≥2, if yes, then go to S408, if not, then end;

[0119] S408, judging whether the coil temperature T2 and the outlet air temperature T3 of the current indoor unit meet the requirements at the same time -T2>10°C and T4-T3>25°C, where, is the average coil tem...

Abstract

The invention provides a prompt control method and system for an indoor unit, the indoor unit and a multi-split central air conditioner. The multi-split central air conditioner comprises at least two indoor units. The prompt control method for the indoor unit is used for the indoor unit and comprises the steps that whether the coil pipe temperature and the outlet air temperature of the current indoor unit are within a working temperature range or not is detected in the operating process; and when the coil pipe temperature and the current outlet air temperature are not within the working temperature range, a dedusting prompt signal for the current indoor unit is sent out. According to the prompt control method for the indoor unit, the dust accumulation condition of a filter screen is detected by detecting the operating parameter change, caused by excessive accumulated dust on the filter screen of the indoor unit, of the indoor unit, a user is effectively reminded to remove dust in time, the heat exchange effect of the multi-split central air conditioner is ensured, and user experience is improved; and the indoor unit applying the method is simple in structure, low in cost and effective in judgment.

Description

technical field [0001] The present invention relates to the technical field of central air conditioners, in particular to an indoor unit prompt control method, an indoor unit prompt control system, an indoor unit and a multi-connected central air conditioner. Background technique [0002] Currently on the market, users often complain that the effect of the multi-connected units on the market is too poor. During the maintenance, it is found that many of the multi-connected units that have been complained have the problem that the dust in the indoor unit filter is too thick, but users usually do not check it themselves, resulting in The dust removal of the filter is not timely, which affects the multi-line heat exchange effect and is not conducive to user experience. In the related art, there is a means of checking the dust accumulation by using the image of the filter screen and analyzing the thickness of the dust in the image, but it needs to add an additional image acquisit...
