| Abstract: | Characteristics of displacement ventilation and mixing ventilation are compared. Combined with a Northwest regional office building, the air conditioning system of evaporative cooling with mixing ventilation and evaporative cooling with displacement ventilation under the same conditions for the design of energy is analyzed. The results show that the latter than the former project to save energy 39.8%. At the same time the use of out- door air for free cooling time, the latter more than the former use of 186 hours/year. |
