Embodiment 1

[0014] Example 1: Using south-facing solar air heat collectors for heat collection and floor heat storage. The concrete implementation technology is as follows: the solar air heat collector 1 is set on the lower wall of the south-facing window of the residential building, and the temperature sensor 2 is set at the outlet of the solar air heat collector 1. When the air at the outlet of the solar air heat collector 1 is heated to the set temperature When the temperature is fixed, the temperature control dampers 3 at the inlet and outlet of the solar air heat collector 1 are automatically opened at the same time, and the circulation fan 4 arranged at the inlet or outlet of the heat collector 1 starts to run automatically. Driven by the circulating fan, the hot air is sent into the air channel 7 of the heat storage floor along the air supply pipe 5, and the hot air absorbs the heat of the air by using the high specific heat capacity of the concrete during the flow along the air cha...

Embodiment 2

[0015] Embodiment 2: Using west-facing solar air heat collectors for heat collection and floor heat storage. The specific implementation technology is as follows: solar air heat collector 1 is set on the west-facing wall of the residential building, and temperature sensor 2 is set at the outlet of solar air heat collector 1. When the air at the outlet of solar air heat collector 1 is heated to the set temperature , the temperature control damper 3 at the inlet and outlet of the solar air heat collector 1 is automatically opened at the same time, and the circulation fan 4 arranged at the inlet or outlet of the heat collector 1 starts to run automatically. Driven by the circulating fan, the hot air is sent into the air channel 7 of the heat storage floor along the air supply duct 5, and the hot air absorbs the heat of the air by using the high specific heat capacity of the concrete during the flow along the air channel 7 of the same process , so that the heat is stored in the co...

Embodiment 3

[0016]Embodiment 3: Utilize south-facing and west-facing solar air heat collectors to combine heat collection and floor heat storage. The use of west-facing solar air collectors can extend the heat collection time and improve heat storage efficiency. The specific implementation technology is as follows: install solar air heat collectors 1-N and 1-W on the south-facing window wall and west-facing wall of the residential building respectively, and these two sets of heat collectors operate in parallel. Set temperature sensors 2-N and 2-W at the outlets of solar air collectors 1-N and 1-W respectively, when the air at the outlets of solar air collectors 1-N and 1-W is heated to the set temperature , the temperature control dampers 3-N and 3-W at the inlet and outlet of the solar air collector 1-N and 1-W are automatically opened respectively, and the circulation fans 4-N and 4-W set at the inlet or outlet of the collector 1 Automatic operation respectively; driven by the circulat...

Abstract

The invention provides a self-controlled hot-air solar floor heat storage system, belonging to the technical fields of renewable energy sources and buildings integration utilization. The system is characterized in that: air is closely circulated in a heat storage system formed by a solar air heat collector, a ventilating duct and a heat storage floor under the drive of a circulating fan, wherein the heat storage floor is used to store and release heat; the heat storage floor is constructed by a waterproof layer, a thermal insulating layer, an air duct, a concrete heat storage layer and a ground decoration layer from the bottom to the top; the air duct in the heat storage floor is arranged in a reversed return mode, and concrete or brick vertical columns are staggered in the heat storage floor; an air door and a circulating fan of the heat storage system can be automatically controlled by a temperature sensor, and the required power can be supplied by a solar cell panel. The heat storage system has the beneficial effects of simple structure, convenience in control, operation reliability, low cost and high building integration degree.

Description

technical field [0001] The invention belongs to the technical field of integrated utilization of renewable energy and buildings, and in particular relates to a self-controlled hot air type solar floor heat storage system. Background technique [0002] For a long time, the thermal stability and comfort of solar-heated residential buildings in villages and towns in cold regions of my country need to be improved urgently. Due to the intermittent and unstable heat supply of solar energy, the indoor temperature of the solar heating room fluctuates greatly. At night or on cloudy days, the indoor temperature often cannot meet the thermal comfort requirements of the human body. Although people have developed a variety of solar heat storage systems and methods, which can solve such problems to a certain extent, there is still an urgent need to develop simple, practical, easy-to-control, It is a solar heat storage technology that is reliable in operation, highly integrated with build...
