Abstract

The utility model relates to the technical field of greenhouse heat preservation, in particular to a hot-cold regulating device for a ground source greenhouse. Currently, most of the areas in China adopt the greenhouse for cultivating various vegetables and crops, however problems exist in the northern areas in China that the temperature in winter is lower, temperature difference between day and night is larger, and the plastic film needs to be covered with a heat preservation quilt at night, therefore increased coal fire, electric heating and other heat source heating are adopted in order to ensure the temperature in the greenhouse to be suitable for the crop growth, which not only wastes large energy, but also pollutes the environment. For solving the problems, the utility model adopts the technical scheme that the regulating device comprises a pipeline, a blower, a valve and a heat exchanger; wherein the heat exchanger is arranged under the greenhouse, and both ends of the heat exchanger are connected with the pipeline; and both ends of the pipeline which extend out of the ground are provided with the blower and the valve respectively. The device also can be used with the solar energy and methane pool in a matching way for regulating the temperature in the greenhouse, therefore the crop growth is ensured, a large quantity of coal is saved, and the ground source heat energy is inexhaustible energy in nature.

Description

The hot cool tone regulating device of ground source green house
Technical field
The utility model relates to the greenhouse insulation technical field, specifically the hot cool tone regulating device of source, a kind of ground green house.
Background technology
In the many areas of China, adopt green house to cultivate various vegetables at present.The plastic film of booth has good printing opacity and the characteristic of preserving moisture, and helps photosynthesis of vegetables in the booth; The sealing property of plastic film well keeps soil moisture, helps the growth of crops.But lower at regional winter temperatures such as northern China, particularly because day and night temperature is bigger, to evening ambient temperature drop to subzeroly rapidly, night is the covering and heat insulating quilt on plastic film, however, crops have frostbite still the time in the canopy.For guaranteeing that crops can not be damaged by frost, also need adopt thermals source such as stove fire or electric heater to improve temperature of shed, both wasted a large amount of coal equal energy sources, polluted environment again.
Summary of the invention
The purpose of this utility model provides the hot cool tone regulating device of source, a kind of ground green house, utilizes the ground temperature of underground, effectively improves the temperature in the green house winter, replaces the heating system of stove fire, heating installation isothermal chamber booth, simple in structure, easy operating.
The technical solution of the utility model is: be made up of pipeline, fan blower, valve, heat exchanger; Underground or in the underground biogas generating pit sweathouse in greenhouse heat exchanger is set at green house, the heat exchanger two ends are connected with pipeline, and the pipeline two ends of elevating above the soil are separately installed with fan blower and valve.
The utility model has solved the problem of crop warmings such as cold district greenhouse gardening vegetables insulation.The source, ground is a kind of inexhaustible thermal source, and a large amount of solar radiation energies are absorbed by underground.Have the characteristics that subsurface temperature is gone up temperature above Ground winter below local frost line, and the soil temperature fluctuation is less, has certain heat storage capacity.When sunshine on daytime was sufficient, the temperature in the green house was higher, opens fan blower, and the gas suction pipeline that temperature in the green house is higher is sent into subterranean heat exchanger, carry out temperature exchange with soil after, send green house again back to, be soil thermal storage.The interior temperature of green house at night descends rapidly, and the gas that temperature in the green house is lower is sent into subterranean heat exchanger, carries out temperature exchange with soil and improves temperature, flows back to ground again, guarantees the temperature in the green house.Be unfavorable for crop growth summer when the temperature in the green house is too high, at this moment can utilize soil temperature to be lower than the characteristics of ambient air temperature, and using this device is the green house cooling, guarantees the suitable crop growth of long-term temperature in the booth.
The utility model has the advantages that: simple in structure, be easy to install, easy to use, rationally utilize soil temperature, pollution-free, not coal combustion, oil, gas etc., energy savings, protection environment.
