Fresh air machine set of evaporation cooling air conditioner

The utility model relates to a fresh air machine set of an evaporation cooling air conditioner. A filter, a high-temperature surface cooling device, a low-temperature surface cooling device, a direct evaporation cooling device and a ventilator are sequentially arranged in the air inlet direction in an air conditioner machine set case, and a water tank is arranged at the lower part in the air conditioner machine set case. The utility model integrates the high-temperature surface cooling device, the low-temperature surface cooling device and the direct evaporation cooling device, and realizes the fresh air whole-year evaporation cooling treatment. In addition, two installation modes: a floor type and a ceiling type can be adopted. Compared with a traditional evaporation cooling air conditioner machine set, the utility model has the advantages of small area of occupied ground, low initial investment, small machine set resistance, good temperature reduction effect and energy saving. In addition, through considering the whole-year operation condition of the same air conditioner equipment, the utility model can be used in dry regions, and can also be used for moderate-humidity and high-humidity regions without being restricted by weather conditions.
