EXPERIMENTAL MEASUREMENTS OF AN AIR CONDITIONER PERFORMANCE

摘要

The performance of the air conditioner was tested in an extensive experimental program using the environmentally controlled chambers in a test facility. Two psychometric rooms provided constant ambient temperature and humidity conditions for a test unit using ASHRAE standard procedures. The indoor and outdoor units were placed into separate environmental chambers, which provided precise temperature, humidity, and airflow conditions for simulation of various operating conditions. The first goal of the experimental program was to define the range of conditions over which the test unit should be tested. The second goal of the experimental studies was to determine the performance of the test unit under the defined conditions. All air conditioner performance data has been collected with air side instrumentation only. Experimental tests were performed using the test unit over a range of outdoor temperatures between 22.4℃ (80℉) and 40.6℃ (105℉) and indoor temperatures between 18.3℃(65℉) and 35℃ (95℉). Analysis of the experimental data was performed by studying air conditioning parameters such as heat rejection rate q_c, compressor power W, system capacity q_e, and coefficient of performance COP. The analysis was accomplished with the variation of a boundary condition. The sensitivity analysis of experimental data gave expected results when compared to those shown by air conditioning units similar to our test unit.
