摘要

现有的多功能热泵机组的制冷兼制热水模式存在结构复杂、能量控制难以满足需求等问题，为此，提出基于数码涡旋压缩机的变容量家庭能源中心系统，并确定制冷兼制热水模式的机组性能系数计算方法。通过实验对比分析制冷兼制热水模式和单独制冷模式的性能，结果表明：与单独制冷模式相比，制冷兼制热水模式的制冷量有所衰减，但机组的总能量输出和性能系数分别提高了17.3%和36.8%。实验研究制冷兼制热水模式在水箱初始温度、不同压缩机负荷和不同环境温度下的动态特性和性能表现。通过分析该模式在各种工况下的性能变化规律，总结控制策略，可保证该模式的安全高效运行。

Abstract

To solve the problems of complex structure and unsuitable capacity control of present multi-function heat pump system

domestic energy system is introduced. A new system performance indicator is chosen to describe the performance of space cooling & water heating mode. By comparison with space cooling only mode

this mode has been proved with a little less cooling capacity but with higher total system performance. Series of experiments are conducted with different initial water temperature in tank

compressor load and outdoor ambient temperature conditions. By analysis of transient characteristics and system performance

the performance rules are concluded. Furthermore

the control strategy is proposed to insure the safe and efficient operation of space cooling & water heating mode.
