The invention relates to the technical field of agricultural greenhouses, and discloses a novel self-circulation
greenhouse. The novel self-circulation
greenhouse mainly comprises a front roof, a rear roof, a heat preservation front wall, a heat preservation rear wall, two side walls, an underground heat preservation layer, a rainwater pond, a cold water pond, a hot
water storage pond, heat circulation accessories and a
power transmission and
energy storage system. The front roof is composed of a photovoltaic photo-thermal
assembly and
glass fiber reinforced plastic plates. The rear roof comprises a slidable triangular support and a heat preservation quilt, wherein the slidable triangular support is covered with the heat preservation quilt. The cold water pond is arranged behind the rainwater pond and connected with the photovoltaic photo-thermal
assembly through a water pump. Hot water which is led out through a photovoltaic photo-thermal
assembly water outlet
pipe is stored in the hot
water storage pond. Rainwater serves as a cooling working medium of the photovoltaic photo-thermal assembly and a
heat transfer working medium for
greenhouse heat circulation. The hot
water storage pond, the heat preservation front wall and the underground heat preservation layer form a greenhouse heat circulation
system through connection pieces. The novel self-circulation greenhouse is combined with the photovoltaic photo-thermal technology, the
land utilization rate can be increased effectively, heat and
electricity are supplied by the novel self-circulation greenhouse, grid-connected power generation can be realized, the comprehensive
utilization rate of
energy resources is high, and the structure is stable.
