Problems solved by technology

[0003] However, in this defrosting mode, it may enter frost-free defrosting in many cases, and the power consumption is obvious
Moreover, when the load is low, most of the modules and outdoor units of the outdoor unit operate in rotation, not all of them are powered on, and the frosting cycle is longer
In addition, when the load is low, if all the modules enter the defrostin

Abstract

The invention provides an outdoor unit defrosting control method and device, and an air conditioner. The method comprises the steps: obtaining a load parameter of an outdoor unit when the outdoor unitneeds to be defrosted, wherein the load parameters are used for representing a load degree of the outdoor unit; determining a defrosting mode of the outdoor unit according to the load parameter; andcontrolling the outdoor unit to defrost in a defrosting mode. According to the outdoor unit defrosting control method, the defrosting mode can be intelligently selected, so that it is guaranteed thatthe unit continuously carries out heating under the condition that the load of the outdoor unit is low, continuous hot air supply in a room is guaranteed, drastic fluctuation of the indoor environmenttemperature is avoided, and the comfortable experience of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of multi-connected air conditioners, in particular to an outdoor unit defrosting control method, device and air conditioner. Background technique [0002] The outdoor unit of the multi-connected air conditioning system usually includes multiple modular outdoor units, which can be operated in a modular manner. At present, in terms of outdoor unit defrosting in multi-connected air conditioning systems, most manufacturers implement conventional defrosting, also known as discontinuous heating defrosting, that is, all outdoor unit modules of the outdoor unit defrost together and end defrosting together. Enter heating mode after frost. This defrosting mode has simple control and short defrosting cycle. [0003] However, in this defrosting mode, it may enter into no-frost defrosting in many cases, and the power consumption is obvious. Moreover, when the load is low, most of the modular outdoor units of t...
