A solar heat collector, a heat collector heat-transfer fluid adjusting valve, a high-temperature heat-transfer fluid circulating pump and a reactor heat exchange coil are circularly connected; a cooling tower, a cooling tower heat-transfer fluid adjusting valve, a low-temperature heat-transfer fluid circulating pump and a liquid accumulator heat exchange coil are circularly connected; a solid-gas chemical reactor, a refrigerant adjusting valve and a refrigerant accumulator are connected; the reactor heat exchange coil, a heat user side adjusting valve, a heat user side and the high-temperature heat-transfer fluid circulating pump are connected; the liquid accumulator heat exchange coil, a color user side adjusting valve, a color user side and the low-temperature heat-transfer fluid circulating pump are connected; the liquid accumulator heat exchange coil, the cooling tower, the cooling tower heat-transfer fluid adjusting valve and the low-temperature heat-transfer fluid circulating pump are circularly connected; and the refrigerant accumulator, the refrigerant adjusting valve and the solid-gas chemical reactor are connected. The device has high energy storage density and can realize cold-heat combined supply and simultaneous storage of heat and cold.

Description

technical field [0001] The invention relates to a device in the technical field of solar light-to-heat conversion and utilization, in particular to a solar thermochemical adsorption composite energy storage device for combined cooling and heating. Background technique [0002] Solar energy is a low-density energy that changes with time. It has the characteristics of intermittent, dispersed and unstable. In order to realize the wide application of solar energy, it is necessary to implement efficient Energy storage technology is a necessary means to solve the contradiction between intermittent, unstable and time difference of energy supply and demand of solar energy. [0003] At present, solar thermal energy storage methods mainly include sensible heat energy storage and latent heat energy storage. Among them, the sensible heat energy storage technology is simple and easy to operate and manage, but the low energy storage density makes the heat storage device bulky. The tradit...
