Embodiment Construction

[0017] Now in conjunction with the accompanying drawings, the working principle of the present invention will be further described. Figure 1-Figure 7 As shown, the central air-conditioning monitoring system switches to the extreme value search optimization algorithm, and manually adjusts the water outlet temperature set point of the chiller to 10°C. The specific operation is as follows: image 3 As shown, click the "freeze water" button in the marked area, as shown Figure 4 As shown, the chilled water adjustment panel window of the main engine will pop up. In the marked area, switch the chilled water outlet temperature from "intelligent control" to "manual control", and then use the keyboard to select "manual SP" in the "manual setting" column. After manually inputting "10.0", it will take effect after confirming with the Enter key.

[0018] Switch the outlet water temperature setting of the chiller to the intelligent mode, that is, put it into the COP maximum value search ...

Abstract

The invention relates to a method for intelligent control over a refrigeration host in a central air-conditioning monitoring system. The method is designed for solving the technical problem that design of a method for intelligent control over a refrigeration host in an existing central air-conditioning monitoring system is poor. The method is characterized in that the central air-conditioning monitoring system of the control method is provided with a frozen water outlet button, the optimal host water outlet temperature of a cold water unit is manually input on a host frozen water adjusting panel, the host water outlet temperature value is set and switched into an intelligent mode, in other words, the host water outlet temperature value is put into the COP maximum value search algorithm, and the optimal host water outlet temperature set value is automatically sought; according to the COP maximum value search algorithm, the running effect of the whole central air-conditioning operation time frame is displayed through one COP curve and another system power energy consumption curve, in other words, the COP slowly searches for the optimal value in the system running period, and the state is constantly kept to the shutdown time. Meanwhile, the central air-conditioning monitoring system is provided with large hosts and small hosts, at most two large hosts are started, and the power and the number of the large hosts and the small hosts are matched with the cold load in real time.

Description

technical field [0001] The invention relates to a central air-conditioning monitoring system, in particular to an intelligent control method for a refrigeration host in the central air-conditioning monitoring system. Background technique [0002] The central air-conditioning system is composed of one or more cold and heat source systems and multiple air-conditioning systems. Generally, the principle of liquid vaporization refrigeration is used to provide the required cooling capacity for the air-conditioning system to offset the heat load of the indoor environment; the heating system is The air conditioning system provides the heat needed to counteract the cooling load of the indoor environment. The refrigeration system is a crucial part of the central air-conditioning system, and its type, operation mode, and structural form directly affect the economy, efficiency, and rationality of the central air-conditioning system in operation. In order to achieve the effect of saving...
