A heat pump and air conditioning system (10, 110, 210, 310, 410, 510) is provided with a thermal storage device (56, 156, 256, 356, 456, 556), a variety of distribution devices for blocking or allowing flow of the system working fluid, and a controller (74, 174, 274, 374, 474, 574) for manipulating the distribution devices to control flow of the working fluid through the thermal storage device (56, 156, 256, 356, 456, 556) to allow thermal energy storage or thermal energy discharge depending upon sensed conditions. In addition, a thermal storage device (610, 710) is provided which is suitable for use in a heat pump and air conditioning system. The thermal storage device includes a container (612, 712) through which refrigerant coils (616, 716) pass. The container (612, 712) is filled with an unencapsulated phase change material (624, 724) having a first melt temperature and an encapsulated phase change material (632, 722) having a second melt temperature higher than the first melt temperature. Further disclosed is a method for conditioning a space by use of heat pump and air conditioning systems incorporating thermal storage. |
