Embodiment 1

[0024] According to an embodiment of the present invention, an embodiment of a control method for an air-conditioning chilled water system is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, Also, although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0025] figure 1 It is a flow chart of a control method for an air-conditioning chilled water system according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps:

[0026] Step S102, acquiring the current air-conditioning load value of the air conditioner.

[0027] Specifically, in the above steps, the air-conditioning load refers to the cooling (heating) load and humidity load of the air-conditioning room, and the cooli...

Embodiment 2

[0075] According to an embodiment of the present invention, an embodiment of a control device for an air-conditioning chilled water system is also provided.

[0076] Figure 9 It is a structural schematic diagram of a control device for an air-conditioning chilled water system according to an embodiment of the present invention, as shown in Figure 9 As shown, the device includes: a first acquiring module 901 , a first determining module 903 and an adjusting module 905 .

[0077] Among them, the first obtaining module 901 is used to obtain the current air-conditioning load value of the air conditioner; the first determination module 903 is used to determine the correction value of the operating parameters of the chilled water system for adjusting the air-conditioning according to the air-conditioning load value; the adjustment module 905 , which is used to adjust the parameter value of the operating parameter of the chilled water system based on the correction value.

Abstract

The invention discloses a controlling method and device for an air conditioner chilled water system, wherein the controlling method comprises the following steps of acquiring a current air-conditioning load value of an air conditioner; determining a corrected value for adjusting an operating parameter of the air conditioner chilled water system according to the air-conditioning load value; and adjusting a parameter value of the operating parameter of the air conditioner chilled water system based on the corrected value. According to the controlling method and device for the air conditioner chilled water system, the technical problem that a value of the operating parameter of the air conditioner chilled water system cannot be controlled in advance due to the fact that the prior art adopts an average value of the operating parameters of the past N circulating periods of the chiller water system as the corrected value of the operating parameter of the next circulating period is solved.

Description

technical field [0001] The invention relates to the field of home appliance control, in particular to a control method and device for an air-conditioning chilled water system. Background technique [0002] In the field of large-scale public buildings, central air-conditioning systems have been widely used, but central air-conditioning systems are the main energy-consuming households of large-scale public buildings. How to further reduce the overall energy consumption of central air-conditioning systems and ensure the quality of comfort in buildings has become Important research content in the field of central air-conditioning system. At present, more than 90% of the central air-conditioning systems in large-scale public buildings in my country adopt classic PID control, PI control, and some are even controlled by manual operation. improve the situation. After research, in the central air-conditioning system of large public buildings, usually, the power consumption of the re...
