Description

Technical Field

[0001] This utility model relates to the field of cooling tower technology, and in particular to a cooling tower for air conditioning rooms. Background Technology

[0002] Air conditioning units commonly use circulating water cooling towers as the core cooling component. These cooling towers employ a three-dimensional frame structure, with a top-mounted air duct and an internal power fan forming an air circulation channel. The sides integrate a water treatment system, consisting of a water storage tank, distribution nozzles, a corrugated heat dissipation packing layer, and a water storage chassis, arranged from top to bottom. Circulating water in the storage tank seeps down through the nozzles in a fine, curtain-like pattern, forming a large-area water film as it passes through multiple layers of packing material, ultimately converging into the bottom water storage area. The specially designed ventilation areas on both sides ensure directional airflow.

[0003] The cooling mechanism of a cooling tower is essentially a heat exchange process between water and air. When the air conditioning unit is running, circulating water carrying heat is pumped into the top of the cooling tower, where it is dispersed into tiny droplets by a spray system and passes through the heat dissipation packing layer under gravity. Meanwhile, the fan continuously draws in cool outside air from the side, and the airflow travels upwards through the water curtain, carrying away heat in two ways: first, the water absorbs a large amount of heat of vaporization during evaporation; and second, heat is transferred through convection when the water comes into direct contact with the air. The cooled water, having undergone sufficient heat exchange, falls into the storage tank and re-enters the air conditioning circulation system, while the warmed, humid air is exhausted into the atmosphere through the top duct, forming a continuous and stable cooling cycle.

[0004] Patent document CN201449167U discloses a high-efficiency, water-saving, energy-saving, and environmentally friendly square crossflow cooling tower that ensures safe operation and cooling capacity. It includes a frame, a fan duct, and a fan; water spraying devices are installed on both sides of the cooling tower; the water spraying packing consists of multiple spaced packing plates; a water spray basin is located above the packing; water distribution nozzles for spraying water into the gaps between the packing plates are located at the bottom of the water spray basin; a water collection basin is located at the lower part of the packing; the packing plates have stepped air inlet and outlet zones on both sides; the middle of the packing plates is a herringbone-shaped corrugated heat exchange zone; a vertical first protrusion prevents water from entering the air inlet zone between the air inlet zone and the heat exchange zone; a vertical second protrusion prevents water from entering the air outlet zone between the air outlet zone and the heat exchange zone; the air inlet zones of adjacent packing plates contact to form a honeycomb-shaped air inlet, and the air outlet zones of adjacent packing plates contact to form a honeycomb-shaped air outlet.

[0005] As in the prior art of the aforementioned patent, the water basin in the patent is used to store the cooling water required for spraying. However, when the water inside the water basin is used up, it is necessary to manually replenish the cooling water or take it from the water collection basin below. However, during the spraying process, the cooling water will decrease due to the evaporation effect. There are no corresponding liquid level sensors in the water basin and the water collection basin, and it is necessary to manually determine whether to add condensate water, which has a low level of intelligence.
