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 defrosting together, it will cause severe fluctuations in the indoor temperature, and the comfort experience of the air conditioner will be seriously reduced
[0004] Aiming at the problem that the indoor temperature fluctuates violently due to the conventional defrosting mode of multi-connected air conditioners under low load conditions, no effective solution has been proposed so far

Abstract

The present invention provides an outdoor unit defrosting control method, device and air conditioner, wherein the method includes: when the outdoor unit needs to defrost, obtain the load parameter of the outdoor unit, wherein the load parameter is used to represent the load of the outdoor unit degree; determine the defrosting mode of the outdoor unit according to the load parameters; control the outdoor unit to defrost in the defrosting mode. The invention can intelligently select the defrosting mode, so as to ensure that the unit continues to heat when the load of the outdoor unit is low, guarantees the continuous supply of hot air indoors, avoids drastic fluctuations in the indoor ambient temperature, and improves the user's comfort experience.

Description

technical field [0001] The invention relates to the technical field of multi-line air conditioners, and in particular, to a defrosting control method and device for an outdoor unit, and an air conditioner. Background technique [0002] The outdoor unit of a multi-connected air conditioning system usually includes multiple modular outdoor units, which can be operated in a modular manner. At present, in terms of defrosting the outdoor unit of the multi-connected air conditioning system, most manufacturers implement conventional defrosting, also known as discontinuous heating defrosting, that is, all the outdoor unit modules of the outdoor unit defrost together and end the defrosting together. Enter heating mode after frost. This defrost mode has simple control and short defrost cycle. [0003] However, in this defrosting mode, it is possible to enter the frost-free defrosting in many cases, and the power consumption is obvious. Moreover, at low load, most of the outdoor uni...
