Wall embedded type solar phase-change energy storage hot-water system, manufacturing method thereof and construction method thereof

The invention discloses a wall embedded type solar phase-change energy storage hot-water system, a manufacturing method thereof and a construction method thereof. The system comprises a phase-change energy storage module which can be embedded into a wall body and a cold-hot water circulating pipeline of a solar heat collector, wherein the phase-change energy storage module is connected with the cold-hot water circulating pipeline; the phase-change energy storage module comprises a first cavity used for circulating solar hot water and a second cavity used for filling a phase-change material; an S-shaped water tube is arranged inside the second cavity; a general hot water outlet and a general cold water inlet are formed in the first cavity. The manufacturing method for the wall embedded type solar phase-change energy storage hot-water system comprises the following steps of: heating a phase-change material to a liquefied state, and then, filling the liquefied phase-change material into a second cavity; sealing
