A super high-rise office building in Fujian Province located in hot summer and warm winter area is expounded on its compound air-conditioning system composed of an efficient integrated evaporative condensing chiller combined with air-cooled multi connected air conditioner.Within the pressure bearing capacity of chiller,pipes and its connection mode,the air-conditioning water system shall be set in combination with the vertical partition of the fresh air system to avoid secondary heat exchange.On this basis,the temperature of the chilled water is reasonably increased,and the energy efficiency is effectively improved.According to the analysis of air-conditioning cooling load and the frequency statistics of outdoor wet-bulb temperature in typical years,it can be seen that the integrated evaporative condensing water chiller under high temperature conditions is used as the fresh air-cooling source.Compared with the conventional water chiller and air-cooled multi-connected outdoor unit as the cooling source,the range of energy saving and emission reduction is higher,which has a good demonstration value.
