Abstract |
The stack effect of a new type condenser installed in a high-rise apartment building was studied numerically. A sirocco fan is introduced to the new type condenser instead of an axial flow fan. The new type condenser intakes the cold air through the lower inlet and exhausts the hot air through the upper outlet. The effects of the building height and frontal wind on the performance of an air-conditioner were analyzed. The performance of an air-conditioner was evaluated by using COP(coefficient of performance) and CGPI(condenser group performance indicator). The hot air was exhausted by the new type condenser at an angle of 50° from the outer wall of the building. If there was no draft, the new type condenser installed in the high-rise apartment building had a good performance and its performance on each floor is not influenced by the stack effect. It is shown that the efficiency of the air-conditioner installed in several floors below the top floor decreased when the frontal wind velocity was greater than 8m/s. |
