Embodiment 1

[0023] figure 1 A schematic diagram showing an optional structure of the multi-line, such as figure 1 As shown, the multi-connection includes: an outdoor machine, multiple internal machines, and a controller connected to the external machine and multiple internal machines; figure 1 The indoor unit is also connected to the control terminal. The control terminal can be a wire controller. When all the indoor units are connected to the wire controller, the wire controller will display the same command synchronously, so as to realize the operation set by the user such as starting and stopping the unit at the same time. The wire controller displays the same content synchronously. The control terminal can also be a remote controller, such as figure 2 shown.

[0024] Wherein, the controller includes: an external machine interface, a control chip, an internal machine interface 1, an internal machine interface 2, an internal machine interface 3, ..., an internal machine interface N....

Embodiment 2

[0038] Based on the multi-connection control method provided in the above-mentioned embodiment 1, a multi-connection control device is also provided in the preferred embodiment 2 of the present invention, specifically, Figure 5 shows an optional structural block diagram of the device, such as Figure 5 As shown, the device includes:

[0039] The monitoring module 502 is used to monitor whether the shutdown instruction of the internal machine is received;

[0040] The external machine control module 504 is connected with the monitoring module 502, and is used for sending a low power consumption command to the external machine if so, and controlling the external machine to enter a low power consumption mode;

[0041] The internal machine control module 506 is connected with the external machine control module 504, and is used for sending low power consumption instructions to multiple internal machines after the external machine enters the low power consumption mode, and contro...

Embodiment 3

[0051] Based on the multi-connection control device provided in the above-mentioned embodiment 2, in preferred embodiment 3 of the present invention, an air-conditioning unit is also provided, including the above-mentioned multi-connection control device.

[0052] In the above embodiment, a low power consumption control scheme for one-to-many units is proposed. After listening to the shutdown command of the internal unit, a low power consumption command is sent to the external unit to control the external unit to enter the low power consumption mode; and After the external unit enters the low power consumption mode, it sends a low power consumption instruction to multiple internal units to control the multiple internal units to enter the low power consumption mode. Through the above-mentioned solution, the problems of high power consumption in the standby state of the existing units and the high cost of low power consumption can be effectively solved, and the low-power standby ...

Abstract

The invention discloses a low-power-consumption multi-split control method and device as well as an air conditioning unit. The method comprises the following steps that whether shutdown instructions of indoor units are received or not are monitored; if yes, a low-power-consumption instruction is sent to an outdoor unit, and the outdoor unit is controlled to enter a low-power-consumption mode; after the outdoor unit enters the low-power-consumption mode, low-power-consumption instructions are sent to the multiple indoor units, and the multiple indoor units are controlled to enter the low-power-consumption mode. According to the low-power-consumption multi-split control method and device as well as the air conditioning unit, the problem of high standby power consumption of multi-split air conditioners in the prior art is solved, low-power-consumption standby of a multi-split unit can be achieved, and the beneficial effects of energy conservation and consumption reduction are achieved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a low power consumption multi-line control method, device and air conditioning unit. Background technique [0002] The high energy consumption of air conditioners has always been a thorny problem for users, because the air conditioner not only consumes energy when it is running, but also consumes power even when it is not running and on standby. The standby power of a traditional unit is at least 10w, and the annual power consumption Up to 70kw.h, the power consumption of one tractor and multiple units will be higher. However, with the improvement of living standards, more and more places will install air conditioners to improve the comfort of work and life. Multiple one-to-one air conditioners meet the needs. In such places, the air conditioners are generally turned on and off at the same time. If the solution of multiple air conditioners is adopted, centraliz...
