Study on the semi-centralized evaporative cooling air-conditioning system´s automation

For the large duct, inflexible use and multiple rooms were not adjusted controlled of central evaporative cooling air conditioning system,we propose a framework which is semi-centralized air-conditioning system of evaporative cooling assisting to mechanical refrigeration. For the majority of medium humidity in the outdoor area weather conditions,we analyse the process of running mode which is based on evaporative cooling in different seasons.Designs an improved automatic control project of semi -centralized air-conditioning system of evaporative cooling assisting to mechanical refrigeration.lt ensures security of complex air conditioning and the best energy-saving.We use KINGVIEW to complete the communication between PC and PLC.We achieve centralized control, data recording and printing.These all have provided the detailed information for the scene maintenance of equipment personnel to enable the operation and maintenance work easier.
