Embodiment 1

[0035] figure 1 is a flowchart of a dual-system control method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0036] Step S101, after the compressor of the first system satisfies the start condition, control its compressor to start;

[0037] Step S102, judging whether the communication between the second system and the first system is normal, and controlling the start-up timing of the compressor of the second system according to the judging result.

[0038] It should be noted that the execution order of step S101 and step S102 is not limited thereto, and may be exchanged or executed simultaneously. For the dual-system air conditioner, which system is defined as the first system and which system is defined as the second system, after any system is powered on, it can be judged whether the system is the first system or the second system according to the dial value of its main board. After the main boar...

Embodiment 2

[0048] figure 2 It is a flowchart of a compressor control method for a dual-system air conditioner according to an embodiment of the present invention, such as figure 2 As shown, the two systems send and receive unit status parameters through the CAN bus, and then control the compressors of the two systems to start according to a certain control method, which can avoid the situation that the compressors of the two systems are turned on at the same time, and improve the reliability and stability of the unit operation.

[0049] Such as figure 2 As shown, each system judges whether it is system 1 (namely the above-mentioned first system) or system 2 (namely the above-mentioned second system) according to the dial value of the main board after power-on.

[0050] If it is system 1, after system 1 meets the compressor start conditions, the compressor will start immediately without waiting.

[0051] If it is system 2, first receive the unit status parameters of system 1 through ...

Embodiment 3

[0054] corresponds to figure 1 The dual system control method introduced, this embodiment provides a dual system control device, such as image 3 The structural block diagram of the dual-system control device shown, the device includes:

[0055] The first control module 10 is configured to control the compressor of the first system to start after the compressor of the first system meets the start condition;

[0056] The second control module 20 is used for judging whether the communication between the second system and the first system is normal, and controlling the start timing of the compressor of the second system according to the judging result.

[0057] For the dual-system air conditioner, which system is defined as the first system and which system is defined as the second system, after any system is powered on, it can be judged whether the system is the first system or the second system according to the dial value of its main board. After the main board is produced, t...

Abstract

The invention discloses a dual-system control method and device and dual-system air-conditioning equipment. The dual-system control method comprises the steps that a compressor of a first system is controlled to be started after the compressor meets the startup condition; and whether a second system normally communicates with the first system or not is judged, and the startup time of a compressorof the second system is controlled according to a judgment result. According to the dual-system control method and device and the dual-system air-conditioning equipment, through the start-stop controllogic of the compressors of the two systems, the situation that the compressors of the two systems are started at the same time is avoided, the situation that the current is tool large when the two systems are started is avoided, the startup success rate of the two systems is increased, and the operating reliability and reliability of a unit are improved.

Description

technical field [0001] The present invention relates to the technical field of air conditioning, in particular to a dual-system control method and device, and dual-system air-conditioning equipment. Background technique [0002] The dual-system air conditioner has two independent refrigeration systems. When the dual system is running, the two systems can control the start and stop of their respective compressors. At present, the compressor start-stop logic of the dual system still uses the single system. The two systems completely independently control the start and stop of their respective compressors. This has a high probability that the compressors of the two systems must be turned on at the same time. It means that the interval between the two compressors being turned on is less than 5 seconds. [0003] However, the current required for starting at the same time is too large, which may easily cause the compressor to fail to start. For example, if the user presses the p...
