Civil engineering structure and evaporative cooling combined closed evaporative cooling cold water system

Abstract

The invention discloses a civil engineering structure and evaporative cooling combined closed evaporative cooling cold water system which comprises a civil engineering shell formed by the utilization of a civil engineering structure in a surrounding manner, wherein a closed heat exchange module is arranged at the upper part of the civil engineering shell; a filling type cooling unit is arranged in the civil engineering shell and is connected with the closed heat exchange module; a stand pipe type indirect evaporative cooler is arranged on the periphery of the filling type cooling unit. According to the closed evaporative cooling cold water system disclosed by the invention, as the lower part of a vertical heat exchange tube group is obliquely arranged, the resistance of secondary air is reduced, so that the air pressure of a fan is reduced; with the adoption of a way of air intake from all the directions, more air quantity can be treated, so that the treatment quantity of high-temperature cold water is increased; due to the increase of the area of an air inlet, the windward air velocity of intake air is reduced, the cooling effect on primary air is enhanced, and the efficiency of the stand pipe type indirect evaporative cooler is improved; in addition, the whole system utilizes clean energy dry air energy, so that the system is an energy-saving and environment-friendly cooling system.

Description

technical field [0001] The invention belongs to the technical field of air-conditioning and refrigeration equipment, and in particular relates to a closed evaporative cooling cold water system combining civil structure and evaporative cooling. Background technique [0002] With the emergence of the global energy crisis and the deteriorating environment, people began to turn their attention to the utilization of various clean and renewable energy sources. Dry air energy is a kind of clean and renewable energy. In the northwest of my country, there is a very rich dry air energy. Based on the characteristics of dry air energy, combining it with evaporative cooling technology, which has the advantages of environmental protection and energy saving, is more suitable for today's The general trend of energy saving and environmental protection. [0003] However, in practical applications, the evaporative cooling technology itself also has many disadvantages, such as: when the amount ...

AI Technical Summary

Problems solved by technology

At present, the length of the heat exchange tubes used in the vertical tube indirect evaporative cooler is equal, and the secondary air needs to go through a turn to enter the heat exchange tubes, which creates a certain resistance to the secondary air, causing the wind pressure of the fan to increase, thereby improving the fan's efficiency. Production investment, and make the secondary air volume in different risers uneven
