Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] See figure 1 , the figure shows a flow chart of an embodiment of the control method of a multi-air conditioner of the present invention, specifically, a flow chart of controlling the indoor fan of the indoor unit of a multi-air conditioner.

[0039] Such as figure 1 As shown, this embodiment realizes the control of indoor fans of one-to-many air conditioners, including the process of intermittently running the indoor fans in a cycle, specifically including the following steps:

[0040] Step 101: Timing the downtime for the indoor fan to stop running.

[0041] After the indoor unit is started, the indoor fan starts and runs according to the wind speed set by the user, sucks the indoor air into the evaporator inside the indoor unit for heat ...

Abstract

The invention discloses a control method for a multi-split air conditioner. The control method includes the steps that the following indoor draught fan intermittent running process is executed in a circulated manner; the downtime when an indoor draught fan stops running is timed, the indoor draught fan is controlled to run at a first set wind speed when the downtime reaches set downtime, and the running time running at the first set wind speed is timed; the indoor draught fan runs at the first set wind speed, and in the process that the running time does not reach the set running time, the indoor environment temperature is obtained, and whether the indoor environment temperature meets the restarting condition of the indoor draught fan or not is judged; if the condition is met, the indoor draught fan is controlled to run at a second wind speed until the running stopping condition of the indoor draught fan is met again, and the indoor draught fan is controlled to stop running; and if the condition is not met, the indoor draught fan is controlled to stop running when the running time reaches the set running time. By means of the control method, the problem of poor temperature comfort caused by the fact that the indoor draught fan cannot be normally started is solved.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to the control technology of an air conditioner, and more specifically relates to a control method for one-driver-multiple air conditioners. Background technique [0002] In the existing one-to-many air conditioner, one outdoor unit runs with multiple indoor units, and the indoor fan in each indoor unit can be controlled independently. Wherein, each indoor unit is provided with a temperature sensor, which is used to detect the indoor ambient temperature, and controls the stop and operation of the indoor fan according to the relationship between the detected indoor ambient temperature and the set temperature. Moreover, the temperature sensors used to detect the indoor ambient temperature are mostly arranged at the air inlet of the indoor unit and near the heat exchanger. [0003] If the indoor ambient temperature of the room where a certain indoor unit is locate...
