Embodiment 1

[0022] In preferred embodiment 1 of the present invention, an air-conditioning control method is provided, which can be directly applied to various air-conditioning units, especially large-scale commercial chillers. Specifically, figure 1 An alternative flowchart showing the method, such as figure 1 As shown, the method includes the following steps S102-S106:

[0023] S102: Detect the operating parameters of the air conditioner, and calculate the thermodynamic parameters of the air conditioner according to the operating parameters;

[0024] S104: judging whether the thermodynamic parameters are abnormal;

[0025] S106: If yes, detect the running state of the air conditioner according to the abnormal thermodynamic parameters, and adjust the air conditioner.

[0026] In the above embodiments, a new air-conditioning unit control scheme is proposed. Its main feature is that it has the function of automatic expert diagnosis, so that the air-conditioning unit can adjust the contr...

Embodiment 2

[0065] Based on the air-conditioning control method provided in the above-mentioned embodiment 1, an air-conditioning control device is also provided in the preferred embodiment 2 of the present invention, specifically, image 3 shows an optional structural block diagram of the device, such as image 3 As shown, the device includes:

[0066] The detection module 302 is used to detect the operating parameters of the air conditioner, and calculate the thermodynamic parameters of the air conditioner according to the operating parameters;

[0067] Judgment module 304, connected with detection module 302, for judging whether the thermodynamic parameters are abnormal;

[0068] The adjusting module 306 is connected with the judging module 304, and is used for detecting the operating state of the air conditioner according to the abnormal thermodynamic parameters and adjusting the air conditioner if yes.

[0069] In the above embodiments, a new air-conditioning unit control scheme is...

Embodiment 3

[0072] Based on the air-conditioning control device provided in the above-mentioned embodiment 2, an air-conditioning unit is also provided in preferred embodiment 3 of the present invention, including the above-mentioned air-conditioning control device.

[0073] In the above embodiments, a new air-conditioning unit control scheme is proposed. Its main feature is that it has the function of automatic expert diagnosis, so that the air-conditioning unit can adjust the control parameters in real time according to the actual operating parameters during the actual operation process, so that the chiller can run The parameters are far away from the operating boundary, and strive to be close to the optimal operating state. On the basis of ensuring the reliable operation of the chiller, the energy saving level of the chiller is greatly improved.

Abstract

The invention discloses an air conditioner control method and device with an expert diagnosis function and an air conditioning unit. The method comprises the steps of detecting the operation parameters of an air conditioner, and calculating the thermodynamic parameters of the air conditioner according to the operation parameters; judging whether the thermodynamic parameters are abnormal or not; and if yes, detecting the running state of the air conditioner according to the abnormal thermodynamic parameters, and adjusting the air conditioner. The problem that in the prior art, a large air conditioning unit is not intelligent enough in control is solved, and the energy-saving level of a water chilling unit is greatly improved on the basis that reliable operation of the water chilling unit isguaranteed.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to an air conditioner control method and device with an expert diagnosis function, and an air conditioner unit. Background technique [0002] Large-scale commercial chillers are the key equipment in commercial central air-conditioning systems. Their operational reliability and energy-saving level are of great significance to the energy saving and consumption reduction of large public buildings. The good operation status of traditional chillers depends on the manual monitoring and maintenance of operation and maintenance personnel. Yes, due to the lag of manual monitoring and the disadvantages caused by weak sense of responsibility, automatic monitoring and adaptive control devices have increasingly become the standard configuration of modern large-scale commercial air-conditioning systems. [0003] For the problem of insufficient intelligence in the control of large...
