[0005] Some patents relate to an indirect evaporative refrigeration method and device that simultaneously generates cold water and cold air. The heat and mass exchange process between air and water is cross flow (cross flow), and only It can generate cold water and cold air at the same time, and cannot realize the function of separately supplying cold air or cold water

The invention discloses a multifunctional multistage counter-flow heat-exchange indirect-evaporation cooling device, wherein heat exchange chambers are uniformly distributed in a case, an air induction duct is arranged between the adjacent heat exchange chambers, the upper opening of the air induction duct is communicated with the air outlet of the upper stage of the heat exchange chamber, the lower opening of the air induction duct is communicated with the air inlet of the lower stage of the heat exchange chamber, the air outlet of a draught fan of the final stage of the heat exchange chamber is communicated to the outside of the heat exchange chamber, an air inlet duct is arranged on the air inlet of the first stage of the heat exchange chamber, surface coolers are uniformly distributed in the air inlet duct or an air supply duct provided with the draught fan is arranged outside the case of the heat exchange chamber, the surface coolers are installed in the air supply duct, and the cold water generated in the water tank of the heat exchange chamber is distributed to users through pipelines or the inlet air temperature is reduced through the surface coolers. The invention not only can reduce the irreversible hot moisture exchange loss in the hot moisture exchanging process of the cold water and the inlet air and improve the heat exchange efficiency, but also can realize the functions of independently supplying the cold water, independently supplying cold air or simultaneously outputting the cold air and the cold water according to different functions and requirements.
Description
technical field [0001] The invention relates to the application of dry air energy renewable energy technology, in particular to a multi-functional multi-stage countercurrent heat exchange indirect evaporation cooling device. [0002] Background technique [0003] Dry air energy evaporative refrigeration technology is adopted in hot and dry climate areas, and the drying characteristics of outdoor air are used for cooling to achieve energy-saving, environmental protection, green, healthy and safe indoor air environment. [0004] Looking at the existing patents and existing technologies, most of the early technologies were evaporative cooling air handlers, which constituted an evaporative cooling full-air air conditioning system. The air handler uses evaporative cooling, and the cold air obtained is sent to the air-conditioned room, and the evaporative cooling air-conditioning system bears the heat and humidity load of the room. The cold source comes from the evaporative refri...
