Embodiment Construction

[0064] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0065] This embodiment provides a multi-connected unit, the multi-connected unit includes an outdoor unit and a plurality of indoor units, and the plurality of indoor units can be installed in a plurality of designated areas, and then the multiple designated areas can be air-conditioned by the plurality of indoor units. adjust. The multi-connected unit provided in this embodiment can solve the problem in the prior art that when multiple indoor units need to perform self-cleaning, the indoor units start cooling at the same time, and the low pressure of the outdoor unit is too low to cause unit protection, so that the self-cleaning action is suspended. question. In addition, it can control multiple indoor units in the multi-connection unit ...

Abstract

The invention provides a multi-split air conditioner self-cleaning control method and device and a multi-split air conditioner, and relates to the technical field of air conditioners. The multi-splitair conditioner self-cleaning control method is used for self-cleaning control of a plurality of indoor units in the multi-split air conditioner, and comprises the following steps of receiving an airinlet temperature value, an air outlet temperature value and an air outlet wind speed value of each indoor unit, calculating the operating parameter value of each indoor unit according to the air inlet temperature value, the air outlet temperature value and the air outlet wind speed value of each indoor unit, obtaining multiple operating parameter values of the multiple of indoor units, and controlling the indoor units to be sequentially self-cleaned according to the multiple operating parameter values and preset parameter values. The invention also provides a multi-split air conditioner self-cleaning control device and the multi-split air conditioner which can execute the method. The multi-split air conditioner self-cleaning control method and device and the multi-split air conditioner can solve the problem that the self-cleaning action is stopped by unit protection caused due to the fact that low pressure of an outdoor unit is too low.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a multi-line self-cleaning control method, device and multi-line. Background technique [0002] At present, with the maturity of central air-conditioning technology, central air-conditioning has gradually entered the homes of ordinary people from the original use of shopping malls and hospitals. [0003] Since the central air conditioner only needs one outdoor unit to match multiple indoor units, it greatly saves the storage space of the outdoor unit; at the same time, most of the indoor units of the central air conditioner can be hidden in the ceiling, making the interior more beautiful and saving indoor space. . Household central air-conditioning has become the first choice for many new properties and young people. [0004] As people's requirements for health and air quality are getting higher and higher, air conditioners, as ordinary household appliances, no...
