Sensible heat-latent heat composite heat storage unit with gas as heat transfer fluid

The invention discloses a sensible heat-latent heat composite heat storage unit with gas as heat transfer fluid. The sensible heat-latent heat composite heat storage unit comprises a heat storage tank. A heat charge process high-temperature gas inflow pipe (8) is reserved on the upper portion of the heat storage tank. A heat release process low-temperature gas inflow pipe (7) is reserved on the lower portion of the heat storage tank. Spherical sensible heat-latent heat composite heat storage balls (3), high-temperature-resisting concrete balls (2), special-shaped concrete blocks and sensible heat-latent heat composite heat storage combs (1) are arranged in the heat storage tank. The spherical sensible heat-latent heat composite heat storage balls (3) are arranged on the upper layer in the heat storage tank. The high-temperature-resisting concrete balls (2) and the special-shaped concrete blocks are arranged on the upper layer and the middle layer in the heat storage tank. The sensible heat-latent heat composite heat storage combs (1) are arranged on the lower layer in the heat storage tank. The advantage that the heat storage density of phase change materials is large is fully utilized, the inner structural characteristics of the heat storage tank are combined, and the heat storage density is maximized.
