Closed type vertical tube indirect evaporation cooling high-temperature cool water unit

Abstract

The invention discloses a closed type vertical tube indirect evaporation cooling high-temperature cool water unit which comprises a vertical tube type indirect evaporation cooler a and a vertical tube type indirect evaporation cooler b. The vertical tube type indirect evaporation cooler a and the vertical tube type indirect evaporation cooler b are arranged in a unit shell body from top to bottom. The lower portion of the vertical tube indirect evaporation cooler is provided with a secondary air inlet. A direct evaporation cooler, a water baffle b and a centrifugal fan are sequentially arranged behind the vertical tube type indirect evaporation cooler a in the air inlet direction. A closed heat exchanger and a water baffle a are sequentially arranged behind the vertical tube type indirect evaporation cooler in the air inlet direction. A water baffle c and an axial flow fan are sequentially arranged on the upper portion of the vertical type indirect evaporation cooler a from bottom to top. According to the closed type vertical tube indirect evaporation cooling high-temperature cool water unit, the vertical tube type indirect evaporation coolers are arranged from top to bottom, the direct evaporation cooler and the closed type heat exchanger are arranged from top to bottom, the centrifugal fan and the axial flow fan are used for respectively controlling primary air and secondary air, and the cool water unit is jointly composed, so that water quality of the cool water unit and water outlet temperature are ensured, and the heat exchange efficiency of the unit is improved to a certain degree.

Description

technical field [0001] The invention belongs to the technical field of air conditioning equipment, and in particular relates to a closed vertical pipe indirect evaporative cooling high-temperature water chiller combined with a closed heat exchanger, a vertical pipe indirect evaporative cooler and a direct evaporative cooler. Background technique [0002] As an efficient cooling technology, evaporative cooling technology is not only widely used in the production of cold air, but also in the production of cold water based on its principle, and it is also becoming mature step by step. In Northwest China, open evaporative cooling high-temperature chillers have been put into use due to the large windy and sandy atmospheric environment in Northwest my country. The blockage and water quality changes caused by windy sand have caused great limitations to the promotion and use of evaporative cooling chillers. At the same time, in terms of unit size, the tube-type indirect evaporative ...

Problems solved by technology

In Northwest China, open evaporative cooling high-temperature chillers have been put into use due to the large windy and sandy atmospheric environment in Northwest my country. The blockage and water quality changes caused by windy sand have caused great limitations to the popularization and use of evaporative cooling chillers.

At the same time, in terms of unit size, the commonly used tubular indirect evaporative cooler, due to the limitation of its structure, leads to a large size of evaporative cooling high-temperature chiller, and its applicability is limited in some places.

[0003] In some special places of use, such as in the air-cooling system of power plants, the circulating water used is demineralized water, which has high requirements on water quality. It is difficult for ordinary open-type evaporative cooling high-temperature chillers to meet their water quality control requirements. Areas where air-cooling systems are widely used are often areas where evaporative cooling technology is more suitable
