Embodiment 1

[0017] In an area of ​​100m 2 On either side of the greenhouse, install 20 heat-absorbing areas of 0.8m 2 non-tracking focused collectors. An insulated water tank with a water storage capacity of 1 ton is installed in the greenhouse. A PE-RT pipe with a length of φ20 mm and a length of 160 m was buried as a radiator at a depth of 0.33 m in the soil in the greenhouse. Then connect them with heat-resistant pipes and temperature-controlled water pumps. All devices of the present invention have just been completed.

Abstract

The invention discloses a non-tracking light-focusing solar geothermal device for green house, comprising: a non-tracking focusing solar collector, a hot water storage unit, a geothermal pipe, and a hot water resistant pipe and a temperature control pump through both of which the non-tracking focusing solar collector, the hot water storage unit and the geothermal pipe are connected; and the non-tracking light-focusing solar geothermal device can also only comprise: the non-tracking focusing solar collector, the geothermal pipe, and the hot water resistant pipe and the temperature control pump through both of which the non-tracking focusing solar collector and the geothermal pipe are connected. The non-tracking light-focusing solar geothermal device for green house has the advantages that: the light receiving area of green house is increased and the received solar heat is delivered to soil via the geothermal pipe, so the temperature of green house is raised, and particularly, the temperature of soil is raised, thus vegetable roots grow better and yield is improved.

Description

technical field [0001] The invention relates to solar geothermal equipment for a greenhouse. In particular, it relates to a non-tracking concentrating solar geothermal device for a greenhouse. Background technique [0002] At present, agricultural greenhouses (or greenhouses) mostly use transparent materials (glass or film) to build a shed on the land to be cultivated, so that sunlight can be injected, and heat is not easy to dissipate, thus forming a room temperature that is conducive to plant growth. [0003] The above-mentioned technology has the following deficiencies: although the room temperature has increased, the soil temperature cannot rise, which is not conducive to the growth of plant roots; the area for absorbing solar heat energy is limited to the area of ​​the greenhouse roof, and for extremely cold regions, the area for absorbing solar heat energy is still limited. Not enough. Contents of the invention [0004] The purpose of the present invention is to su...
