地源热泵户型蓄冰中央空调的探讨

针对目前国内空气源热泵户型中央空调存在COP值低、机组耗电量大，冬季融霜控制困难、室温波动大，机组无真正的能量调节，单相电机组额定制冷（制热）量太小，给用户带来不便，以及加剧了城市电网的供需矛盾等问题，提出了地源热泵户型蓄冰中央空调的解决方案,并探讨双热力膨胀阀，双蒸发器和盘管外融冰的机组结构形式，还就我国城乡人民生活水平提高、住宅面积扩大和多样化、城市建筑和环境的限制、电力部门将推行居民家庭“峰谷电价”等方面，分析了地源热泵户型蓄冰中央空调广阔的市场前景。

Discussion on Ice-Storage Centralized-Air-Conditioner with Ground-Source-Heat-Pump

The authors considered low COP, great using of electricity, difficulty of thaw in winter, waving greatness of indoor temperature, no really energy adjustment. It is also considered that single phase unit don't content user because it's small supply and increase the load of city electricity network etc in air-source-heat-pump in internal centralized-air-conditioner for house.One project is given to solve these problems, using ice-storage with ground-source-heat-pump. Moreover, its structural form of double expansion valves, double evaporators and thawing-ice outside coils. The market foreground of this conditioner is analyzed from the improvement of people's standard of living, the increase of house area, the limits of sight and environment of city building, the coming policy of residents' electrovalence in valley and so on.
