Solar heating device for passive solar house

Abstract

The invention discloses a passive solar heating device for a solar house. The passive solar heating device for the solar house is arranged in a double-layer heat exchange circulating mode, hot water in a heat storage water tank circulates from the upper layer to the lower layer in sequence and flows back to the heat storage water tank at last, heat which is not exchanged in an upper heat storage assembly can be absorbed by a lower heat storage assembly, and the lower heat storage assembly is of an inner and outer alloy shell type closed structure, so that the heat preservation of heat of the lower layer can be increased, and the heat is prevented from dissipating downwards; the upper heat storage assembly is of a regular array structure, so that the heat dissipation capability of the upperheat storage assembly to the upper outside can be greatly increased, and the heat exchange effect is increased. The specific heat capacity of the structure of the passive solar heating device is large, so that the indoor temperature difference can be small even at night; the heat storage water tank of the passive solar heating device flows in or out in a tangent mode, so that scale in the heat storage water tank can be effectively washed, the flowing property of the heat storage water tank is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to a solar heating device for a passive solar house, belonging to the technical field of solar heating. Background technique [0002] Passive house is an energy-saving building that can completely rely on solar energy and indoor appliances to heat the human body in winter. This energy-saving building is of great significance to low-carbon environmental protection. It conforms to the design of green energy and is of great significance to the sustainable development of society. For passive houses, the design of solar heating is crucial for passive houses. The current solar heating devices are generally realized only by disc-type heat exchange tubes or heat exchange fins. Due to the limited specific heat capacity of this structure, the heat exchange structure has a large temperature difference between day and night, which is not conducive to the heating requirements of indoor temperature. Although the current However, the current fl...

Problems solved by technology

The current solar heating devices are generally realized only by disc-type heat exchange tubes or heat exchange fins. Due to the limited specific heat capacity of this structure, the heat exchange structure has a large temperature difference between day and night, which is not conducive to the heating requirements of indoor temperature. Although the current However, the current floor heating structure is relatively simple, and its heating effect is still prone to fluctuations, and most of the current floor heating is prone to heat loss to the ground, and the indoor heat application is less, and the heat utilization rate is not high.
