Embodiment Construction

[0024] Combine below figure 1 The technical solution provided by the present invention is described in more detail.

[0025] The invention provides an air conditioner defrosting method, comprising the following steps: controlling at least one of the indoor units with people in the room not to participate in the defrosting.

[0026] For example, there are a plurality of indoor units in a working state with no one in the room (or called no user in the room), and the above air-conditioning defrosting method controls at least one of these indoor units not to participate in defrosting. The so-called non-participation in defrosting means that the indoor unit does not flow into the refrigerant and does not participate in the defrosting cycle. The specific implementation method is, for example, controlling the opening of the electronic expansion valve on the refrigerant channel of the indoor unit. If the electronic expansion valve is closed, no refrigerant flows into the indoor unit,...

Abstract

The invention discloses an air conditioner defrosting method and an air conditioner, and relates to the field of air conditioners. The air conditioner defrosting method is used for optimizing the defrosting effect of the existing air conditioner. The air conditioner defrosting method includes the following steps that the ratio X of the rated capacity sum of indoor units in manned rooms to the rated total capacity sum of all working indoor units is monitored; and if X is smaller than or equal to N, at least one of all the indoor units in the manned rooms does not participate in defrosting, wherein N is a set value. According to the air conditioner defrosting method in the technical scheme, before defrosting, the indoor units are distinguished into the indoor units in the manned rooms and the indoor units in the unmanned rooms. During defrosting, all or part of indoor units in heating modes in the manned rooms do not participate in defrosting, in other words, at least one of the indoor units in the manned rooms does not participate in defrosting circulation, by means of the arrangement, the situation that the temperatures of the indoor units are affected due to defrosting is avoided,the temperature difference change caused by defrosting is effectively reduced, the comfort of users is improved, and the experience of the indoor users corresponding to the indoor units is better.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an air conditioner defrosting method and an air conditioner. Background technique [0002] The multi-connected air conditioner includes multiple indoor units, and the working mode of each indoor unit is the same. Under the defrosting condition, each indoor unit participates in defrosting. [0003] The inventors have found that there are at least the following problems in the prior art: the existing multi-connector will cause fluctuations in the indoor temperature during defrosting, which affects the stability of the indoor temperature. Contents of the invention [0004] The invention proposes an air conditioner defrosting method and an air conditioner to optimize the defrosting effect of the existing air conditioner. [0005] The invention provides an air conditioner defrosting method, comprising the following steps: [0006] Proportion X of the sum of the rated capacities of ...
