Problems solved by technology
[0004] The present invention solves the serious hysteresis of existing public places such as commercial offices and large venues due to large changes in personnel activity and mobility, and the heat emitted by the human body leads to changes in the ambient temperature and is detected by the air conditioner before adjusting the operating parameters of the air conditioner. To solve the problem, a multi-connected air conditioner control method is proposed. By detecting the amount of human activity, the indoor unit control correction coefficient is generated, and then the corresponding control is executed. This method is advanced and starts before the human body feels the uncomfortable environment. Adjustment, so that it can respond to changes in room heat load in time

Embodiment 1
[0039] Embodiment 1, in public places such as commercial offices and large venues, due to large changes in personnel activity and mobility, and the heat emitted by the human body causes changes in the ambient temperature and is detected by the air conditioner before adjusting the operating parameters of the air conditioner, there is a serious lag In order to solve the problem of safety, this invention proposes a multi-connected air conditioner control method. By detecting the amount of human activity, the indoor unit control correction coefficient is generated, and then the corresponding control is executed. This method has early warning, and the human body does not feel the uncomfortable environment Adjustments are made so that they can respond to changes in the room's thermal load in a timely manner. The multi-connected air conditioner control method in this embodiment includes the following steps:
[0040] Steps for setting the indoor unit control correction coefficient;

The invention discloses a control method for a multi-split air conditioner. The control method includes the following steps that an indoor unit control correction factor is set; and the air conditioner is controlled, specifically, (1) an indoor unit capacity need reference value is calculated, (2) a human body moving signal is detected, (3) the value of the indoor unit control correction factor is determined, (4) the actual indoor unit capacity need value is calculated, and (5) the actual indoor unit capacity need value is sent to an outdoor unit controller, so that a compressor control parameter is adjusted and corresponding control is executed. The control method for the multi-split air conditioner has advancement, by detecting the current human body activity amount and according to the empirical value of the heat quantity possibly generated by the current activity amount, the value of the indoor unit control correction factor is determined, adjustment is started before human bodies do not feel uncomfortable in the environment, and then the change of the heat load of a room can be timely responded, so that the problem that the environment temperature difference is sharply changed due to the change of the heat emitted by the human bodies is avoided.
Description
technical field [0001] The present invention relates to the technical field of air conditioning control, in particular to a multi-connected air conditioning control method. Background technique [0002] Multi-connected air conditioners are mostly used in public places such as commercial offices and large venues. There are large changes in the activity and mobility of people. When the activity of people is large or the number of people is large, the body will release more heat; When the number of people is small, the heat released by the human body is small. Due to the above changes, the heat load of the room will also change accordingly, so that the temperature of the room will rise or fall. Existing multi-connected air conditioners usually only use the indoor ambient temperature as the control object. When the indoor ambient temperature is higher than the set temperature, the indoor unit sends it to the outdoor unit according to the difference between the set temperature an...
