Circulating cooling water system has a flow statistics function, in the sewage outlet and make-up water outlet installation of two electromagnetic flowmeter, the signal will be transmitted to the management system, because the electromagnetic flowmeter has an instantaneous flow rate and cumulative flow rate display and record function, you can get a whole operating season of sewage statistics, make-up water statistics, evaporation loss statistics.
Can provide a running season of economic data analysis data, for improving the operation of economic management is essential. To supplement the slow-release scale inhibiting agent supplementation and dosing provides data support, the internal management system can be automatically based on the number of agents per ton of water to be supplemented, or through the concentration of the proportion of the agent is automatically calculated by the number of supplemental agents, converted into metering pump action time or the number of pulses, this function fully realized the quantitative management of the agent dosing, and save the cost of the agent, but also effectively avoid the lack of the agent triggering the invisible accidents of operation. This function can realize the quantitative management of pharmaceutical dosage and save the pharmaceutical cost, and can effectively avoid the invisible accident caused by the lack of pharmaceutical, and effectively extend the service life of the equipment.
System in the design and installation of sewage electromagnetic flowmeter or water replenishment electromagnetic flowmeter fully take into account the uncertainty of the system's pressure, the uncertainty of the installation distance, and the choice of electromagnetic flowmeter to do supporting the use of telemetry signals to do the transmission of information. Air conditioning circulating water system is the use of tap water as a cooling carrier, quickly take away the heat transferred by the compressor of the refrigeration unit. This paper focuses on the design of air conditioning cooling water system.
The design of the recirculation system should have features that reduce or avoid system downtime associated with the installation of new equipment. These features should apply to the cooling system in the centralized station and the chilled water piping framework within the building, some of which include the need to reserve piping valves and pipe covers for the installation of future equipment, such as water-cooled racks, centralized air conditioners, computer room air conditioners, and centralized station equipment. The centralized station should consider the ability to add chillers, pumps and cooling towers as the load increases. Total flexibility is often limited by the piping distribution system within the centralized station. When the data center is online, changes in piping size are generally prohibited to achieve capacity increases from the standpoint of avoiding operational disruptions and implementation costs.
Circulation systems need to have the ability to expand to accommodate increased loads. The piping system within the building should be designed to support the density of cold loads in the building. Energy consumption of pumps, system flexibility and circulation storage also need to be considered to determine the total investment. The plant room should have sufficient space for future circulating water units, pumps and cooling towers. The chilled and cooling water systems in the plant room should be sized in such a way that they can be well adapted to changes in the chilled and cooling water systems from the day of operation until the capacity is increased and until the future planned capacity is reached.
The design of the circulating water system should be easily installed in a visible and accessible location. The designer shall provide access needed to maintain and operate valves, controls, sensors, and large equipment. In the centralized machine room, lifts, hoists, cranes, etc. may be provided for moving heavy equipment and components. Cold water pipe and cooling water pipe should avoid conflict with the cooling system equipment moving; like water pumps, chillers, such mechanical equipment arrangement, should be convenient to completely replace; cut-off valve location must also be able to replace the inconvenience of service interruption. Therefore, their arrangement and the integration of the entire piping system is very important.
