由杨亮、袁晗、彭经纬、张春路（通讯作者）撰写的论文Performance modeling of air cycle heat pump water heater in cold climate在International Journal of Refrigeration, 2016年第87卷在线发表。论文通过仿真模拟研究了空气压缩热泵循环用于寒冷地区热泵热水器的性能。结果表明，空气压缩热泵循环适用于即热型热泵热水器，当环境温度下降时制热水能力不会下降，且系统COP降幅低。全年运行能耗与普通蒸气压缩式热泵热水器相比，具备较强的竞争力。这一研究再次表明空气压缩热泵循环是解决寒冷地区热泵供热的一条可行途径。

论文摘要：

Air (reverse Brayton) cycle has promising features in cold climate heat pump applications. In this study, an air cycle heat pump water heater (ACHPWH) simulation model considering the off-design performance of components was developed and validated with experimental data from literature. With this model, the performance of ACHPWH was numerically compared with two typical vapor compression heat pump water heaters (VCHPWH) under two different heating schemes, namely instantaneous heating and recirculation heating. For instantaneous heating, the COP of ACHPWH is comparable to that of VCHPWH when supplying high temperature water or operating at low ambient temperature. A significant improvement on annual performance would be achieved as well if higher efficient compressor and expander were applied in ACHPWH system. For recirculation heating, although the COP gap got larger, ACHPWH would save plenty of heating time when operating at low ambient temperature.
