Embodiment 1

[0074] like figure 1 As shown, in any of the above embodiments, optionally, the multi-stage outdoor heat exchange unit includes a first outdoor heat exchange unit 302 and the second outdoor heat exchange unit 304, and the multi-stage indoor heat exchange unit includes a first indoor heat exchange unit 602 and the second indoor heat exchange unit 604, the multiple reversing assemblies include the first reversing assembly and 202 the second reversing assembly 204, the multiple air return ports include the first air return port 102 and the second air return port 104, the first return air port The air port 102 is connected to the second port of the first reversing assembly 202, the third port of the first reversing assembly 202 is connected to the first outdoor heat exchange unit 302, and the fourth port of the first reversing assembly 202 is connected to the first indoor Heat exchange unit 602; the first air return port 102 is connected to the second port of the second reversing ...

Embodiment 2

[0078] In addition, a first throttling device 402 (close to the outdoor heat exchanger) and a second throttling device 404 (close to the indoor heat exchanger) are respectively arranged on both sides of the first gas-liquid separator 502, and the second gas-liquid separator The third throttling device 406 (near the outdoor heat exchanger) and the fourth throttling device 408 (near the indoor heat exchanger) are respectively arranged on both sides of the 504, and the opening and closing of different throttling devices are controlled by the controller, combined with the exchange Control the flow direction of the refrigerant in the components, and open different refrigerant defrosting circulation paths for defrosting the outdoor heat exchanger in different working conditions to meet the defrosting requirements of different working conditions.

[0079] In any one of the above embodiments, optionally, the reversing assembly is a four-way valve; the throttling device includes one or ...

Embodiment 3

[0084] like Figure 4 As shown, in the above embodiment, optionally, in the defrosting mode, determine the preset temperature range to which the outdoor ambient temperature belongs, so as to determine the defrosting control parameters corresponding to the preset temperature range, specifically including: In mode, if it is detected that the outdoor ambient temperature belongs to the first temperature range, the control opens the throttling component on the first refrigerant flow path, adjusts the first reversing component to the first flow direction, and controls the operation of the first compression chamber so that the high temperature The gaseous refrigerant flows into the first outdoor heat exchange unit on the windward side through the first reversing assembly, and flows into the corresponding first indoor heat exchange unit through the first refrigerant flow path after performing a heat exchange operation.

[0085] In this embodiment, in the first defrosting control strat...

Abstract

The invention provides an operation control method, an operation control device, an air conditioner and a storage medium. The operation control method comprises the following steps that the relation between a coil temperature of an outdoor heat exchanger and a defrosting temperature threshold value is detected to meet a defrosting condition, and a defrosting mode is entered; in the defrosting mode, a preset temperature interval to which the outdoor ambient temperature belongs is determined to determine defrosting control parameters corresponding to a preset temperature interval; and the defrosting operation is executed according to the defrosting control parameters, wherein the air conditioner is provided with a plurality of parallel refrigerant defrosting circulation flow paths, and the different defrosting control parameters are used for controlling different refrigerant defrosting circulation flow paths to be conducted so as to control the high-temperature refrigerant to enter the outdoor heat exchanger to dissipate heat and defrost. According to the technical scheme, the defrosting efficiency can be improved, and the energy consumption can be reduced.

Description

technical field [0001] The present invention relates to the technical field of household control, in particular to an operation control method, an operation control device, an air conditioner and a computer-readable storage medium. Background technique [0002] When the air conditioner is running in the heating mode in winter, frosting will occur on the outdoor heat exchanger. The defrosting scheme in the related art is to switch the air conditioner to the refrigeration cycle to make the outdoor heat exchanger dissipate heat and defrost. For air conditioners with independent compression systems, the above defrosting scheme has the following defects: [0003] When the same defrosting scheme is adopted for different degrees of frosting, on the one hand, it is easy to cause waste of energy consumption, and on the other hand, it affects user experience. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in th...
