specific Embodiment approach 1
[0058] A method for optimizing the water temperature adjustment time of a chiller under this specific embodiment, the flow chart is as follows figure 2 shown, including the following steps:
[0059] Step a. In the n-time working environment, monitor the following key parameters:
[0060] Water temperature adjustment time t i , where i=1,2,...,n;
[0061] Water volume N i , where i=1,2,...,n;
[0062] The difference between the current water temperature and the target water temperature ΔT 1i , where i=1,2,...,n;
[0063] Difference between current water temperature and ambient temperature ΔT 2i , where i=1,2,...,n;
[0064] fan speed n i, where i=1,2,...,n;
[0065] Step b. Determine the independent variable and dependent variable:
[0066] Because in the adjustment process, the water temperature adjustment time is expected to be the shortest, and the water temperature adjustment time is related to the water volume, the difference between the current water temperatur...

[0094] A method for optimizing the water temperature adjustment time of a chiller under this specific embodiment, the flow chart is as follows image 3 As shown, on the basis of the specific embodiment 1, the further definition also includes the following steps:
[0095] Step h. Under the condition of the same secondary factors, compare the change of water temperature adjustment time before and after the change of key parameters, if:
[0096] The water temperature adjustment time is shortened, and the optimization is successful;
[0097] The water temperature adjustment time becomes longer, and the key parameters are adjusted in the opposite direction.

[0098] A method for optimizing the water temperature adjustment time of a chiller under this specific implementation mode uses the FTD-WTC001 chiller developed by our company as the test object. The front panel, rear panel, upper panel and controller of the chiller are as follows Figure 4-7 shown.
[0099] Under different working conditions, key parameters are monitored as shown in the table:
[0100] Table 1 key parameter record form
[0101]
[0102] Based on the key parameters in Table 1, the method of the present invention is simulated with Matlab 2014, and the program is as follows:
[0103]
[0104]
[0105] The result of running the program is as Figure 8 As shown, the following results can be seen from the figure:
[0106] alpha 1 =0.8102
[0107] alpha 2 =0.8002
[0108] alpha 3 =0.5981
[0109] alpha 4 =0.6610
[0110] From the above results, it can be seen that the water volume is the most critical factor affecting the adjustment time, followed...
