Description

Solar Thermal Storage Greenhouse

technical field

The utility model belongs to the improvement of the structure of a solar greenhouse, in particular to a solar heat storage type greenhouse.

Background technique

In northern my country, greenhouses are used to produce vegetables in winter. During the day, the temperature in the greenhouse is raised by the radiation of sunlight, and at night, the temperature required for vegetable growth is maintained by means of heat preservation and heating. It is necessary to open the air outlet in time to lower the temperature in the greenhouse as soon as possible, so that the heat accumulated in the greenhouse will be lost in vain. When the temperature of the greenhouse drops at night, a large amount of coal must be fired to increase the temperature in the greenhouse.

Contents of the invention

The purpose of the utility model is to provide a solar thermal storage greenhouse, which utilizes solar heat collection to store the radiant heat of sunlight during the day, and releases the stored heat at night to increase the temperature in the greenhouse and save energy.

The utility model is realized in the following way: a solar thermal storage greenhouse, comprising a back wall, gables on both sides and a daylighting shed supported by an arch shed; The solar heat collector of the water tank is positioned by the positioning device, and the underground heat preservation and heat storage container corresponding to the solar heat collector is installed at the lower part of the soil in the greenhouse, and the heat dissipation tanks are evenly distributed along the length of the greenhouse at the front end of the greenhouse. The water inlet pipe and the water outlet pipe of the heat preservation water tank of the solar collector are respectively connected with the water inlet and the water outlet of the corresponding side of the heat preservation heat storage container. The water inlet and the water outlet are respectively connected with the water inlet pipe and the water return pipe of the radiator, and a water pump is installed on the water inlet pipe.

In the utility model, the angle between the solar heat collector hinged on the inner side of the rear wall ceiling and the rear wall ceiling can be adjusted. In summer, the solar water heater can be recovered and attached to the inner side of the ceiling to avoid direct sunlight and reduce the sun’s impact on the heat collector. Loss, thereby increasing the service life of solar collectors. When the greenhouse is put into production in winter, adjust the solar collector to the working angle of receiving sunlight. During the day, open the control valve on the pipeline connecting the solar thermal collector and the thermal insulation storage container, and close the control valve on the pipeline connected between the thermal insulation thermal storage container and the radiator. During the day, the heat energy generated by the solar thermal collector passes through the water medium , is stored in the underground thermal storage container under the action of the circulating water pump; when the temperature in the greenhouse drops at night, close the control valve on the pipeline connecting the solar thermal storage container and the thermal storage container, and open the connection between the thermal storage container and the thermal storage container. The control valve on the pipeline between the radiators, under the action of the circulating water pump, transfers the heat energy accumulated during the day to the greenhouse through the water medium through the radiator, so as to provide the heat energy needed for the growth of the crops in the greenhouse. The utility model utilizes solar energy heat collection to accumulate the radiant heat of sunlight during the day, and releases the stored heat at night to increase the temperature in the greenhouse and save energy.
