Abstract

Air conditioning is a major factor for the amount of power consumption in an infrastructure. Therefore it's important to improve the overall efficiency of the air conditioning system. Reducing the power consumption can decrease the demand for energy and lower the emission of greenhouse gases. In this paper, we present that the use of BLDC run fan for condenser in chiller system of air-conditioners will have better efficiency than the conventionally used induction motor. The rate of Air flow determines the temperature difference between the coolant entering the condenser and leaving the condenser. As the power loss in induction motor is higher than BLDC motor, higher speed can be obtained using BLDC motor than IM motor with same power rating. So, when speed increases the coefficient of performance increases. The simulation performed in CFD (computational fluid dynamics) software brings out the performance of BLDC motor and Induction motor, proving the better coefficient of performance with BLDC motor.

基于CFD的无刷直流电机和感应电机的冷凝器在冷水机组冷却器系统中的建模、仿真和比较

空调是基础设施耗电量的一个主要因素。因此，提高空调系统的整体效率是非常重要的。减少电力消耗可以减少能源需求，减少温室气体排放。本文提出了在空调制冷系统中采用无刷直流运行风机作为冷凝器比传统的感应电机具有更好的效率。空气流速决定了进入冷凝器和离开冷凝器的冷却剂之间的温度差。由于感应电机的功率损耗高于无刷直流电机，因此在相同额定功率下，使用无刷直流电机可以获得比IM电机更高的转速。因此，当速度增加时，性能系数增加。在CFD(计算流体动力学)软件中进行了仿真，得到了无刷直流电机和感应电机的性能，证明无刷直流电机具有更好的性能系数。
