Evaporative cooling air-conditioning applications to solve existing problems and ideas Abstract: At present, the concentration of evaporative cooling air-conditioning system in the western region of China has been more and more widely used, but its major drawback that the air duct, use the flexibility is poor and can not be achieved separately adjustable control in multiple rooms. Centralized system for the shortcomings of this paper is different from the traditional fan-coil unit with a new semi-centralized air system evaporative cooling air-conditioning system, and the theoretical feasibility analysis carried out. Keywords:: evaporative cooling semi-centralized air-conditioning system environment protection and energy 1. Evaporative cooling technology, the status quo Evaporative cooling process is based on water as a refrigerant, and because they do not use CFCs, and thus on the atmospheric environment pollution-free, and can be used directly fresh air, greatly improving indoor air quality. With the usual principles of mechanical refrigeration, as the evaporation from the refrigerant to provide cooling capacity. But for evaporative cooling, the evaporation of water to obtain the use of energy, it is not, after the evaporation of water vapor is compressed, and then condensing back to liquid water to evaporate. Generally can add moisture to maintain the evaporation process of the implementation. 2. Evaporative cooling air conditioner problems At present a number of high-rise buildings in China’s western region, public buildings, is still widely used mechanical refrigeration air conditioning system. While these systems provide a comfortable working and living environment, but air conditioning units and evaporative cooling compared to one-time investment of its huge, high running costs, repairs and maintenance complex, and would lead to “sick building syndrome” and cause environmental pollution. After the outbreak of SARS epidemic, especially the
