Cross-seasonal heat storage system for heat charging and discharging

Abstract

The invention relates to a cross-seasonal heat storage system for heat charging and discharging. The system is designed according to the position of a solar cross-seasonal heat storage water body heat charging and discharging pipeline on a pool, and comprises a heat storage water body with an upper opening, a heat preservation top cover covering the upper opening, a water body heat charging part and a water body heat discharging part. The water body heat charging part comprises a heat charging hot water pipeline, a heat charging circulating pump, a heat charging heat exchanger and a heat charging cold water pipeline which are communicated; the water body heat release part comprises a heat release cold water pipeline, a heat release heat exchanger, a heat release circulating pump and a heat release hot water pipeline which are communicated; and the water body heat charging part and the water body heat releasing part penetrate through the heat preservation top cover from the upper portion of the heat preservation top cover and are inserted into the heat storage water body. Compared with the prior art, the pipeline of the heat storage system does not penetrate through the waterproof layers at the bottom and on the side face of the water body and enters the water body from the top cover of the water body, the hidden danger that leakage exists in connection of an impermeable membrane material of the water body and a water pipe is prevented, the problem of waterproof reliability caused by inlets in the bottom and the side wall of the water body in the prior art is solved, and the cost of the water body is reduced.

Description

technical field [0001] The invention relates to a cross-seasonal heat storage system for charging and discharging heat, which belongs to the field of building heating. Background technique [0002] Pit-type water body heat storage is a more commonly used cross-seasonal heat storage technology at present. Due to the effect of natural convection, the water temperature in the water body is distributed along the depth gradient. The heating cycle of the water body is that cold water is pumped out from the bottom of the water body and heated and then hot water enters the upper part of the water body. [0003] The current heat extraction and heating method is to insert water at the bottom or edge of the water body, but there is a hidden danger of leakage in the connection between the anti-seepage membrane material of the water body and the water pipe, which seriously affects the safety and life of the water body. The leakage here is at the bottom of the water body, and it is store...
