Description

Technical Field

[0001] The present invention relates to the technical field of central air-conditioning water treatment equipment, in particular to fully automatic integrated water treatment equipment for central air-conditioning. Background Art

[0002] Central air conditioning systems provide wide-area cooling, regulating temperature through the coordinated circulation of refrigerant and water. The core principle is that a compressor drives a refrigerant, such as Freon, through a phase change cycle between an evaporator (which absorbs heat) and a condenser (which releases heat). Water, acting as a heat transfer medium, carries heat between the chilled and cooling water systems. Chilled water delivers cold air to the fan coil units, while cooling water dissipates waste heat to the cooling towers. During this process, impurities, minerals, and microorganisms in the water as it flows through metal pipes and heat exchangers can pose three major risks: calcium and magnesium ions form scale when heated, reducing heat transfer efficiency; dissolved oxygen and chloride ions corrode metal pipes; and algae and bacteria grow, clogging equipment and posing health risks. Water treatment equipment automatically doses scale inhibitors to inhibit scale formation, corrosion inhibitors to form a protective film that slows corrosion, and biocides to inactivate microorganisms. Filters remove suspended particles, maintaining stable water quality, ensuring efficient heat transfer, reducing energy consumption, and extending equipment life. Ultimately, this ensures efficient, safe, and economical operation of the air conditioning system.

[0003] Usually, this water needs to be cleaned through multiple processes in order to maintain the cooling effect for a long time. However, due to the large number of cleaning processes, existing devices usually rely on manual processing, which is not conducive to the long-term use of the device. Therefore, a fully automatic integrated water treatment equipment that can be easily processed is needed. Summary of the Invention

The water is filtered repeatedly with the rotation of the baffle, which reduces the frequency of replacing the filter element and improves the practicality of the device.

[0016] 2. The quantitative dosing mechanism is used to provide medicines in appropriate proportions according to the weight of water. After the mechanism sends water to the upper side of the pressure plate through the filtering mechanism, the pressure plate slides down due to the water pressure.

[0017] 3. The particle removal mechanism is used to filter out scale particles and gravel debris that may be carried in the water. The mechanism uses a spiral to create a vortex in the water flow, thereby using centrifugal force to discharge particulate impurities and send the water into the purification kettle. The mechanism reduces the retention rate of impurities in the system through reasonable layout. BRIEF DESCRIPTION OF THE DRAWINGS
