本文描述了在加热模式下对一台3吨级R-22分体式热泵进行的大量试验。测试包括150个稳态性能测试、18个循环测试和18个除霜测试。在测试工作期间，制冷剂加注水平相对于标称值在70%到130%之间变化；室外温度在17华氏度（8.3摄氏度）、35华氏度（1.7摄氏度）和47华氏度（8.3摄氏度）下改变了三个水平；室内空气流量为额定空气流量的60%至150%；扩展设备从一个固定的- 孔板的热膨胀值。介绍并比较了大量稳态循环和除霜试验的详细性能数据。引文:ASHRAE Transactions，第117卷，第2部分，魁北克省蒙特利尔

This paper describes extensive tests performed on a 3-ton R-22 split heat pump in heating mode. The tests contain 150 steady-state performance tests, 18 cyclic tests, and 18 defrost tests. During the testing work, the refrigerant charge level was varied from 70% to 130%, relative to the nominal value; the outdoor temperature was altered by three levels at 17°F (–8.3°C), 35°F (1.7°C) and 47°F (8.3°C); indoor airflow rates ranged from 60% to 150% of the rated airflow rate; and the expansion device was switched from a fixed-orifice to a thermal expansion value. Detailed performance data from the extensive steady-state cyclic and defrost testing performed were presented and compared.
