首次介绍了采用热线风速仪测量分体式房间空调器室外机组内外流场的方法和流场测试结果。以 KFR70 - LW/Bd某型空调器室外机组为测试对象进行了流场分布测试。根据测试数据 ,详细分析了风扇进、出口的气流速度的分布 ,为空调器室外机组换热器的性能研究、提高制冷效率、降低气动噪声提供了有效的技术支持。
The method of measuring the flow field inside and outside the outdoor unit of split-type room air conditioner and the flow field test result using the hot wire anemometer for the first time are introduced. The flow field distribution test was carried out with KFR70 - LW / Bd outdoor unit as the test object. According to the test data, the distribution of airflow velocity at the inlet and outlet of the fan is analyzed in detail. This provides an effective technical support for the performance study of the heat exchanger of the outdoor unit of the air conditioner, improving the refrigeration efficiency and reducing the aerodynamic noise.
