摘　　要：为考察三套管蓄能型热泵（TRESE）的制冷性能，对一台2HP样机的4种制冷模式分别进行了实验研究．实验结果表明，夜间室外干球温度低于25℃时，三套管蓄能型热泵的周期制冷COP较高，其值在2．4～3．7之间；三套管蓄能器与空气源热泵联合供冷模式的COP较高，在室外千球温度为35～43℃的范围内，其值在2．4～2．9之间，较空气源热泵单独供冷模式的COP提高了15％；当三套管蓄能器供冷水流量为40L／h时，联合供冷期间三套管蓄能器的供冷百分比稳定在7．7％左右，受室外气温的影v向不大；若将样机中3组三套管蓄能器同时开启，则三套管蓄能器的供冷率在联合供冷中的比例可提升至23％．To perceive cooling behaviors of the triple-sleeve energy storage exchanger （TRESE）based energy storage heat pump system, a 2 HP prototype was manufactured and run to manifest the cooling performance of the novel sys- tem. Experiments included four operation modes under space cooling state. Results reflect that cooling cycle COP is from 2.4 to 3.7 when dry bulb temperature is lower than 25℃ during nighttime. COP of TRESE cooling combined with air source heat pump is from 2.4 to 2.9 as outdoor dry bulb temperature is from 35 to 43 ℃, which rises by 15% more than that of space cooling by air source heat pump only. When flow rate of cold water through TRESE is 40 L/h, the cooling rate of TRESE in combined cooling is 7.7% with scarcely wave, even with ambient temperature changes. If opening all three TRESEs, the cooling rate of TRESE in combined cooling will be increased up to 23%.
