Fig. 2 is the flow chart of an energy-saving control method embodiment of data center machine room air conditioning terminal of the present invention, and the method that the present embodiment provides for carrying out Energy Saving Control under electric refrigeration mode.As shown in Figure 2, the energy-saving control method of this data center machine room air conditioning terminal can comprise:
Step 201, the air blow and return temperature of image data central machine room tail end air conditioner equipment.
Step 202, according to the automatic control refrigeration system transmission supply water temperature raising request of above-mentioned air blow and return temperature to data center machine room, with the chilled water temperature making automatic control refrigeration system improve robot control system(RCS).
Particularly, according to above-mentioned air blow and return temperature to the automatic control refrigeration system of data center machine room send supply water temperature improve request can be for: the running temperature allowed when the server determined in air blow and return temperature and data center machine room also has difference, and in above-mentioned automatic control refrigeration system cold-storage tank liquid level and temperature can the emergent cooling of the load data central machine room scheduled time length time, send supply water temperature to above-mentioned automatic control refrigeration system and improve request.
When specific implementation, the upper limit that can arrange supply water temperature is 20 degree, and that is, supply water temperature is the highest can be raised to 20 degree.In the present embodiment, the running temperature that server in the air blow and return temperature and data center machine room of the robot control system(RCS) determination tail end air conditioner equipment of data center machine room allows also has difference, and in above-mentioned automatic control refrigeration system cold-storage tank liquid level and temperature can the emergent cooling of the load data central machine room scheduled time length time, namely initiate to automatic control refrigeration system the demand improving robot control system(RCS) chilled water supply water temperature, by the lower power consumption of equipment in automatic control refrigeration system, automatic control refrigeration system is obtained indirectly energy-conservation.
Wherein, the running temperature that the server in above-mentioned data center machine room allows is 30 to 35 degree; Above-mentioned scheduled time length can require sets itself according to systematic function and/or realization, and the present embodiment is not construed as limiting this, and for example, above-mentioned scheduled time length can be 15 minutes.
Further, according to automatic control refrigeration system from air blow and return temperature to above-mentioned data center machine room send supply water temperature improve request after, if after automatic control refrigeration system improves supply water temperature, the air blow and return temperature collecting tail end air conditioner equipment in the data center machine room of the first quantity raises, then improve the blower fan frequency of corresponding tail end air conditioner equipment, to strengthen heat exchange air quantity; Above-mentioned first quantity is not more than predetermined value.Wherein, predetermined value can require sets itself according to systematic function and/or realization, and the present embodiment is not construed as limiting this, and for example, above-mentioned predetermined value can be 3.
