Solar heating system for building with cast-in-situ open-web floor

Abstract

The invention relates to a solar heating system for a building with a cast-in-situ open-web floor, which belongs to a system for providing heat for the building by using solar energy. In the proposal, sunlight is focused on a heat energy receiver by a concentration chip, and then hot air generated by the heat energy receiver is blown to the floor by a fan. The floor is formed by cast-in-situ of thin-walled box bodies; the thin-walled box bodies form a hot air cycle channel in the floor by using connecting channels; the hot air heats the floor after entering the floor, so the entire floor becomes a heat dissipating integration. The lower part of the thin-walled box bodies is provided with an air outlet leading to a room; when the air outlet is opened, the hot air is discharged to the room directly to heat the room quickly. The proposal makes use of the energy of the nature, so the solar heating system is clean and environment-friendly and saves cost and power; besides, the proposal makes full use of own structural characteristics of the building to avoid the problems of installation of additional devices and space occupation.

Description

technical field [0001] The invention relates to an energy-saving building, in particular to a system for heating a building by using solar energy and a cast-in-place hollow floor. Background technique [0002] At present, in terms of heating methods for buildings, most buildings install radiators in the rooms and use gas heating and water heating for heating. Maintenance, if there is a problem with the heating pipe in a building, almost the entire building has no heating, and the specific heating time needs to be arranged uniformly, and it cannot be used reasonably according to the weather, time, and occupancy. More unfavorable for energy conservation. There are also some that use heating pipes buried in the floor of the building, and then use gas to circulate the heated water in the pipes to heat. The floor heating is clean and uses the principle of rising hot air to make full use of heat, but this method is mainly used for later decoration. The construction carried out i...
