Eco-friendly greenhouse

Abstract

The subject of the application is an energy-saving greenhouse mounted on the ground, which is characterized in that it consists of four side walls, an upper outer cover mounted at an angle and an upper wall with a solar collector (2) mounted on the outer cover and side walls with a broken cross-section, where the outer cover (1) is mounted on the side walls of the greenhouse and connected to the upper wall, the solar collector (2) is mounted in the upper part on the outer cover (1) and in the lower part on the upper wall of the greenhouse, wherein the solar collector consists of a three-layer cellular polycarbonate, wherein the upper and lower layers have semi-transparent protective coatings, the middle layer is a heat-absorbing layer filled with a black coolant, at the end of which there is a coolant collector with a circular cross-section, and the solar collector (2) has the shape of an approximately inverted letter Z,pipelines (3) with a circulation pump (4) are mounted along the side and top wall of the greenhouse connected to the collector (2) and in the lower part connected to the heat accumulator (14) connected by pipes to the ground air collector (12) with a damper (13) with an air inlet (10), wherein the air collector has an external air heater (5), a supply air duct (8) mounted along the side wall of the greenhouse with a supply duct fan (9), connected to the heat accumulator (14), an exhaust air duct (6) mounted along the side wall with an exhaust duct fan (7), connected to the ground air collector (12).,
