本文描述了一项实验研究，以确定日本市场上现有的变频热泵的稳态特性、循环效应和结霜/除霜效应，并根据当地室外空气温度数据计算其季节效率。结果表明，该热泵的APF比传统的定速热泵高15%。如果消除循环和结霜/除霜损失，变频热泵的APF将进一步提高2%至6%。对于逆变器热泵的评估，仅APF是不够的，需要额外的参数，如年度舒适系数（ACF）。单位:SICitation:研讨会，ASHRAE交易，1985年，第91卷，pt。你好，檀香山2B

This paper describes a study to experimentally determine the steady-state characteristics, cyclic effect, and frosting/defrosting effect of a inverter heat pump currently available on the Japanese market and compute its seasonal efficiency based on the local outdoor air temperature data.It has been found that the APF of this heat pump is higher by 15% than that of the conventional fixed-speed heat pump. If cyclic and frosting/defrosting losses are eliminated, the APF of the inverter heat pump will be further improved by 2%to 6%. For the evaluation of an inverter heat pump, APF alone is not sufficient, and an additional parameter such as an annual comfort factor (ACF) is needed.Units: SI
