Problems solved by technology

[0002] In the related technology, the load end and the cold source end of the air conditioning equipment of the chiller are independently controlled, and linkage cannot be formed. Therefore, the frequency control of the chilled water pump is separated from the water valve opening control, which cannot meet the actual water demand, resulting in unreasonable pump control.

Embodiment 1

[0047] In one embodiment of the present invention, an operation control method of air-conditioning equipment is provided, which is used for controlling the air-conditioning equipment, wherein the air-conditioning equipment includes a chilled water pipeline, and a water valve and a chilled water pump are arranged on the chilled water pipeline.

[0048] figure 1 It shows one of the flowcharts of the operation control method of the air conditioner according to the embodiment of the present invention. Specifically, the control method includes:

[0049] Step 102, obtaining the target air supply temperature of the air conditioner;

[0050] Step 104, determining the target opening degree corresponding to the water valve according to the target air supply temperature, and controlling the opening degree of the water valve to adjust to the target opening degree;

[0051] Step 106, adjusting the operating frequency of the chilled water pump according to the target opening.

[0052] In ...

Embodiment 2

[0054] In one embodiment of the present invention, when the fan of the air conditioner is the first fan, and the first fan is a variable frequency fan, figure 2 It shows the second operation control method of the air conditioner according to the embodiment of the present invention, specifically, the control method includes:

[0055] Step 202, obtaining the return air temperature of the air conditioner;

[0056] Step 204, determine the target operating frequency corresponding to the first fan according to the return air temperature, and control the first fan to work at the target operating frequency;

[0057] Step 206, adjusting the target air supply temperature according to the target operating frequency.

[0058] in, image 3 Shown is the third operation control method of the air conditioner according to the embodiment of the present invention, which is a specific step of step 206, including:

[0059] Step 302, reducing the target air supply temperature based on the fact ...

Embodiment 3

[0070] In one embodiment of the present invention, when the fan of the air conditioner is the second fan, and the second fan is a fixed-frequency fan, Figure 4 It shows the fourth operation control method of the air conditioner according to the embodiment of the present invention. Specifically, the control method includes:

[0071] Step 402, obtaining the target return air temperature of the air conditioner;

[0072] Step 404, adjusting the target opening degree according to the target return air temperature.

[0073] In this embodiment, the air conditioner includes a second fan, and the second fan is a constant frequency fan. In the case of setting a fixed-frequency fan, the fan frequency cannot be adjusted. At this time, obtain the target return air temperature of the air conditioner and adjust the water valve of the air conditioner according to the target return air temperature.

[0074] Wherein, when the second fan is set, that is, the fan is a fixed-frequency fan, the ...

Abstract

The invention provides an operational control method of air conditioning equipment, air conditioning equipment and a storage medium. The operational control method of the air conditioning equipment comprises the steps that target air supply temperature of the air conditioning equipment is obtained; a target opening corresponding to a water valve is determined according to the target air supply temperature, and an opening of the water valve is controlled to be adjusted to the target opening; and the operational frequency of a chilled water pump is adjusted according to the target opening. The communication connection between a tail end control cabinet and a machine room main control cabinet is built, the target opening started at present of the water valve is sent to the machine room main control cabinet in real time, so that the main control cabinet correspondingly adjusts the operational frequency of the chilled water pump according to the current target opening of the water valve, sothat the water pump frequency of ''an upstream'' is adaptive to the water valve opening of ''a downstream'', the feedwater quantity adapts to the actual water quantity demand, the water pump iscontrolled more reasonably, and the integral operational energy efficiency of the air conditioning equipment is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of air-conditioning equipment, and in particular, relates to an operation control method of an air-conditioning equipment, an air-conditioning equipment, and a computer-readable storage medium. Background technique [0002] In the related technology, the load end and the cold source end of the air conditioning equipment of the chiller are independently controlled, and linkage cannot be formed. Therefore, the frequency control of the chilled water pump is separated from the water valve opening control, which cannot meet the actual water demand, resulting in unreasonable pump control. . Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art. [0004] To this end, the first aspect of the present invention proposes an operation control method of an air conditioner. [0005] A second aspect of the invention...
