针对燃气机热泵热水器在全年制取生活热水的同时可满足对建筑冬季供暖夏季供冷的需求，对系统不同季节运行模式下的性能进行了实验研究，并利用季节一次能源利用率(SPER)的评价方法对系统性能进行评价．结果表明：夏季供冷兼制生活热水模式下，系统 SPER 为2.16，比单纯制取生活热水模式季节性能提高了46.9%；春/秋自然通风兼制生活热水模式下，转速为1,000,r/min 时系统 SPER 最高为1.99；冬季供暖兼制生活热水模式下，系统SPER为1.82，比单纯制取生活热水模式季节性能提高了15.9%．

A gas engine-driven heat pump water heater(GEHPWH)was designed and built to experimentally test its heating and cooling performances under different seasonal operating modes,which could provide domestic hot water all year round,and at the same time could meet the heating and cooling requirements of building in winter and in summer spaces. Furthermore,an index of seasonal primary energy ratio(SPER)was presented to evaluate the per-formance of the whole system. The experimental results show that the SPER is 2.16 for providing cooled air and do-mestic hot water simultaneously in summer,which can be up to 46.9%higher than the running mode of providing domestic hot water only. In spring and autumn,the highest SPER is about 1.99 atthe rotating speed of 1 000 r/min when the GEHPHW is used to provide hot water as well as fresh air. In winter,the SPER is about 1.82 since the dou-ble requirements of both space and water heating,which is 15.9% higher than the running mode of providing domes-tic hot water only.
