Problems solved by technology
Evaporative cooling chemical treatment method, although the treatment effect is relatively obvious, but it needs to monitor the amount of dosing, and it is necessary to manually add scale inhibitors, corrosion inhibitors, surface coating anti-corrosion layer and other methods to treat water quality, the whole method is too cumbersome; and The method of using high-frequency electromagnetic field to treat evaporative cooling water quality is not yet stable, and its connection with the evaporative cooling unit is an external connection, which is not convenient for transportation and installation due to its large size
[0004] If the water quality treatment device integrating filtration and purification can be directly attached to the evaporative cooling air handling unit, it can not only avoid scaling, corrosion and bacterial growth in the circulating water, but also solve the problem of external water quality treatment device. The problems caused by the large footprint and inconvenient transportation and installation

An evaporative cooling air handling unit with a water quality purification device comprises a unit casing. Two opposite side walls of the unit casing are provided with an air inlet and an air outlet respectively. A filter, an indirect evaporative cooler, a direct evaporative cooler, the water quality purification device and an air feeder are sequentially arranged in the unit casing according to the flowing direction of fresh air after the fresh air enters. The water quality purification device is connected with the direct evaporative cooler through a connecting wing, a corresponding unit casing top wall above the indirect evaporative cooler is provided with an air outlet, and a secondary exhaust fan is arranged in the air outlet. The water quality purification device and the evaporative cooling air handling unit are highly modularized and integrated, the occupied space is much smaller compared with other handling modes, the evaporative cooling air handling unit is simple to operate and convenient to maintain, and the water quality handling problem of an evaporative cooling air conditioner which is an open type system is solved.
Description
technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration equipment, and in particular relates to an evaporative cooling air treatment unit with a water quality purification device. Background technique [0002] Evaporative cooling air-conditioning technology is a technology that uses water as a refrigerant for evaporative heat absorption and cooling. This environmentally friendly, energy-saving and efficient air-conditioning technology can effectively use natural energy to improve indoor air quality. As a green and environmentally friendly refrigeration technology, evaporative cooling air conditioners are constantly developing and progressing. However, due to their special open characteristics, the cooling medium-circulating water has problems of scaling, corrosion and bacterial growth, which will lead to air-conditioning heat and humidity exchange. Efficiency drops, which seriously affects the service life of equipment and po...
