Embodiment
Below in conjunction with drawings and Examples, the utility model is described in detail.
The present embodiment, for the cooling system of 100MeV cyclotron recirculated water, introduces its system composition and control method.The cooling system of 100MeV cyclotron recirculated water comprises: a large-scale closed water tower and 10 refrigerant compressors, see secondary cycle part in Fig. 2, the controllable device of large-scale closed water tower is ventilating fan and the water pump for water tower spray, and the startup of ventilating fan and spray can improve the cooling effect of water tower greatly.10 refrigerant compressors (label is AB, CD, EF, GH, IJ) are divided into 5 groups, and often group is used to different cooling grades.
In the utility model closed water tower and refrigerant compressor with the use of: the former makes full use of the natural resources (winter, effect was more obvious) such as environment, water evaporation endothermic, the latter is used for the meticulous adjustment of extreme environment (hot summer), high power load Water Under temperature, and both complement each other.
The high stability implementation method of cyclotron circulating water cooling system provided by the utility model, the set point of circulating water temperature when first determining to run, then the closed water tower and some refrigerant compressors that are used for cooling circulating water are divided into multiple cooling grade, determine each unlatching of cooling grade or the relation between the temperature of stopping and described set point, according to the temperature of the recirculated water that water temperature receptor monitors, determine unlatching or the stopping of Current Temperatures point cooling device at different levels, make the temperature all-the-time stable of recirculated water in limited range.
As shown in Figure 1, the circulating water temperature set point when SV in Fig. 1 is the operation of water machine, can select arbitrarily the concrete control mode of the present embodiment within the scope of 20 DEG C ~ 30 DEG C.Thick vertical line designates the observed temperature of recirculated water, above horizontal line+represent higher than set point, below-represent lower than set point.Cooling way is divided into 6 grades, specific as follows: 1. water tower blower fan, water pump, 2. compressor A, B, 3. compressor C, D, 4. compressor E, F, 5. compressor G, H, 6. compressor I, J, and determine what temperature spot to start or stop cooling device at different levels at respectively.
As long as desired temperature (SV) is given, within the scope of the heat load of design (the machine is 450 ~ 500kW), water machine system passes through PLC control program, can automatically open by the temperature spot shown in Fig. 1 or stop cooling device at different levels, keep recirculated water be stabilized in ± 0.3 DEG C within the scope of, long-time running is reliable and stable.In the present embodiment, concrete control mode is shown in Fig. 1, when water temperature is lower than set point SV, does not first open any cooling device; When water temperature reaches set point SV, water pump and the blower fan of water tower are started working, as water temperature starts to decline, then until lower than set point 0.6 DEG C time, stop the water pump of water tower and blower fan; If after opening the water pump of water tower and blower fan, water temperature continues to rise, then, when water temperature is higher than set point 0.1 DEG C, open compressor A, B, as water temperature starts to decline, then until lower than set point 0.5 DEG C time, stop compressor A, B; If after unlatching compressor A, B, water temperature continues to rise, then, when water temperature is higher than set point 0.2 DEG C, open compressor C, D ... according to diagram, the like, the high stability realizing cooling system controls.
Water temperature receptor is placed in the entrance of circulating water cooling system water pump, can set operating temperature value (such as, set point SV=25 DEG C) by temperature display meter in proper range.The PLC of circulating water cooling system is compared with measured value according to this set point, automatically perform corresponding control flow, make the temperature all-the-time stable of recirculated water within limited range, to meet the demand of accelerator (or other large-scale power apparatus) stable operation.
This antihunt means, both natural environment was taken full advantage of, power savings is obvious, meticulous adjustment can be realized, compare with usual manner, extend on the one hand the period of waves of water temperature, greatly reduce the fluctuation amplitude of water temperature on the other hand, thus make the temperature stabilization of recirculated water within the≤scope of ± 0.3 DEG C.If by further for cooling way refinement, such as be divided into 12 grades, the temperature stability of recirculated water can rise to ± and 0.1 DEG C.The method of this high stable, does not need the expenditure of too much funds substantially, but greatly can promote the industrial grade of water chiller, therefore great popularization.
Obviously, those skilled in the art can carry out various change and modification to the utility model and not depart from spirit and scope of the present utility model.Like this, if belong within the scope of the utility model claim and equivalent technology thereof to these amendments of the present utility model and modification, then the utility model is also intended to comprise these change and modification.
