412629¾ ^ R71ia688 Fifth, the description of the invention (2) The improvement and the bottleneck energy requirements of the system's operation can only solve the control effect of the period. After the invention is completed, the above cooling equipment is finally used and set the thermostat. The operating conditions in the direct control can meet the conditions of the present invention, so that the system can prevent the efficiency from being turned over. The following is here: First, please) When the configuration is shown to obtain the pole, yes, and other problems such as fruit and energy can be completed. The use of this water tower is better than the cooling of the fan horse for a practical purpose. It is appropriate to cool the various parts, and there are many cases in the source festival to create a number of the control results, to meet the demand for cold and variable energy, the main cooling water and saving the amount of cooling water, the overall need to face Consolidation. In the practice, that is, the main device of the ice water is based on the control of the auxiliary amount of the water, and then the effect of supplying water is solved. The system does not need to judge the various types of the invention machine (or sensor) The set-up of the pump-control mode of the control mode provides a condition, dosage, and amendments. However, in the case of the entire case, there is still a failure to integrate the entire system. Strictly speaking, in the previous case, it was not possible to reach the pre-miss. Continuous research and change mainly on one or one of the manufacturing processes that need to be measured for cooling. Speed and action, to achieve the shortcomings of cold, variable energy can meet the actual and effective improvement of the process cooling water. The system needs to control the demand of water supply. The operation of the system is described in detail with the schematic description of the specific embodiment of the present invention. For example, refer to the diagram in the second figure, which mainly includes 1) and a controller (2 3).
