摘要： The present invention discloses a system of energy-efficient and constant-pressure parallel-coupled fluid-transport machines, which can flexibly and massively provide gas and water to every fabrication unit. The system of the present invention comprises: variable-frequency centrifugal fluid-transport machines, pressure gauges, power meters, flow meters, and controllers. The performance curves of the abovementioned system of parallel-coupled fluid-transport machines and the system impedance curves of the loads are analyzed theoretically and built in the controllers together with the equal-efficiency curves provided by the manufacturer. When the system is operating, the data detected by the pressure gauges, power meters, and flow meters are compared with the built-in data to obtain the optimal energy-efficient conditions as the operational criteria of the system of the present invention.

摘要： A cooling tower for automatically adjusting flow rates of cooling water and cooling air with variations of a load comprises a plurality of thermometers; a hygrometer; at least one controllers; a cooling water pump; and at least one cooling towers connected in parallel. The desired data, such as optimum allowance operating range, heat transferring property of cooling towers, outer gas bulb temperature, approach and relations therebetween are calculated numerically and then are built in the controller. As the cooling tower is operated, by the measuring of the thermometer, messages are transferred to the controller, the practical data and predetermined data are compared in the controller so as to acquire an optimum cooling water flow and cooling air flow. Then, the controllers are used to control the cooling fan in the cooling pump and cooling towers. Thus, an optimum flow rate is acquired. Therefore, the power is saved. The flow rate of the present invention is changed with the load of the ice water mainframe. Only the flow rate of the cooling air is adjusted, but also the flow rate of cooling water is adjusted. The power of the cooling towers is saved greatly.
