Problems solved by technology
[0002] With the progress of society, people not only pay attention to the functionality of air conditioners, but also consider their economy and environmental protection. Evaporative cooling air conditioners are becoming more and more influential as environmentally friendly air conditioners. Many air conditioners are faced with the problems of high outlet temperature and low efficiency, so a widely applicable evaporative cooling air conditioning unit is proposed to further save energy and at the same time use multi-stage evaporative cooling to reduce the outlet air temperature and improve the performance of the air conditioning unit
