Water supply and return system through combination of evaporative air cooler and cooling tower

Abstract

The invention discloses a water supply and return system through the combination of an evaporative air cooler and a cooling tower. The water supply and return system includes the cross-flow cooling tower and a control cabinet, the cross-flow cooling tower is connected with an evaporative air cooler cooling system through a water supply pipe, the evaporative air cooler cooling system is connected with a water return tank through a water return pipe, the water return tank is further connected with the cross-flow cooling tower through a water supplement pipe, and a solenoid valve is arranged on the water return pipe and connected with the control cabinet. According to the water supply and return system through the combination of the evaporative air cooler and the cooling tower, the cooling water is supplied to the evaporative air cooler cooling system by using the cross-flow cooling tower, so that the evaporative air cooler can have the lower air supply temperature and expands the use range of the evaporative air cooler.

Description

Technical field [0001] The invention belongs to the technical field of air conditioning equipment, and specifically relates to a water supply and return system combined with an evaporative air cooler and a cooling tower. Background technique [0002] Evaporative cooling is a technology that relies on the temperature difference between the dry and wet bulbs of outdoor air to cool down and uses water to evaporate and absorb heat. Evaporative cooling, as an environmentally friendly, energy-saving, and healthy air-conditioning method, has become a powerful trend in the development of air-conditioning as the environment is deteriorating, energy is depleted, and health is threatened. It is developing in a broader space and applied to humans. In all aspects of production and life, evaporative cooling technology also has problems such as limited application range and limited temperature drop. [0003] The limited application range is mainly reflected in the fact that although evaporative ...

AI Technical Summary

Problems solved by technology

As an environmentally friendly, energy-saving and healthy air-conditioning method, evaporative cooling has become a strong trend in the development of air-conditioning in today's deteriorating environment, depletion of energy sources, and threats to health, and it is developing towards a wider space and applied to human All aspects of production and life, but evaporative cooling technology also has problems such as limited application range and limited temperature drop

[0003] The scope of application is not wide, mainly reflected in: Although evaporative cooling technology can greatly reduce energy consumption, its application scope is limited due to its own fundamentals

In the northern dry area, because the outdoor air is relatively dry, the temperature difference between the dry and wet bulbs of the air is large. For the direct evaporative cooling process, the dry bulb temperature of the outlet air depends on the wet bulb temperature of the inlet air. The lower the wet bulb temperature of the inlet air, the lower the temperature of the outlet air. The lower the dry bulb temperature of the air, the greater the temperature drop of the treated air. In the humid southern regions, due to the small temperature difference between the dry and wet bulbs of the outdoor air, the temperature drop is limited, and the evaporative cooling technology alone cannot Meet the requirements of indoor temperature and humidity, so the application of evaporative cooling technology in humid areas in the south is limited
