Central air conditioning circulating water automatic dosing device intelligent and precise dosing water quality stabilization system

Description :

  The automatic dosing device for air conditioning water is a core equipment for water quality treatment designed specifically for central air conditioning circulating water systems. It mainly solves the problems of scaling, corrosion, and bacterial and algal growth that occur during the operation of cooling and chilled water systems. This device uses automated control methods to accurately add chemical agents such as corrosion inhibitors, scale inhibitors, and bactericides to the pipeline system, maintaining the chemical balance of the water body, ensuring heat exchange efficiency, and extending equipment service life. It is suitable for water treatment conditions in HVAC systems of various commercial complexes, office buildings, hotels, and industrial plants.

  The automatic dosing device usually consists of a solution tank, a metering pump, a liquid level gauge, a safety valve, a check valve, a pulse damper, a Y-shaped filter, and a fully automatic control system. The main material is mostly made of PE or stainless steel, which has strong corrosion resistance; The metering pump has high-precision adjustment function, with flow error controlled within ± 1%, and supports 0-100% manual or automatic adjustment. The control system can perform logical operations based on time cycles, water flow signals, or parameters such as conductivity and pH feedback from online water quality monitoring devices to achieve intermittent or continuous dosing, in accordance with relevant industry standards such as GB 50050 "Design Specification for Industrial Circulating Cooling Water Treatment".

  When selecting an automatic dosing device for air conditioning water, it is important to consider the retention capacity, replenishment rate, and system materials (such as carbon steel, copper, stainless steel, etc.) of the circulating water system. For open cooling tower systems, emphasis should be placed on the combination of sterilization, algae removal, and scale inhibition functions; Closed chilled water systems pay more attention to corrosion inhibition performance. If the on-site space is limited, an integrated modular structure can be chosen; If there is a high demand for intelligence, it is recommended to choose a control cabinet with remote communication interfaces (such as RS485/Modbus) to connect to the Building Automation System (BAS) and avoid chemical waste or insufficient protection caused by manual dosing based solely on experience.

  When installing the automatic dosing device for air conditioning water, it should be placed in a well ventilated and flat machine room. The length of the suction pipe should not be too long to prevent cavitation, and a back pressure valve should be installed in the outlet pipeline to ensure measurement accuracy. In daily maintenance, it is necessary to regularly check the liquid level of the solution tank, replenish the medication in a timely manner, and clean the sediment at the bottom; Check the status of the metering pump diaphragm and one-way valve to prevent leakage or blockage. Common faults such as unstable flow are often caused by clogged inlet filters and require regular cleaning; If there is an alarm shutdown, the power supply voltage and sensor signals should be checked for normal operation to ensure long-term stable operation of the device and maintain high efficiency and energy saving of the air conditioning system.
