Abstract

The invention discloses a heat accumulating type solar energy greenhouse which is combined with solar energy heat collecting and heat accumulating technology and agricultural greenhouse booth technology, wherein a solar energy heat collecting and heat accumulating device is additionally arranged on the back wall of a sunlight greenhouse and can be used for storing excess solar energy in the daytime in a phase-change heat storing material; and the heat is released through a blower when the temperature is decreased at night, so that the temperatures of the greenhouse in the daytime and at night are adjusted.

Description

A kind of heat-storage solar energy greenhouse

Technical field

The present invention relates to solar thermal utilization and agricultural greenhouse technology, refer in particular to a kind ofly in conjunction with the solar energy heat-collecting heat-storage technology, have the solar energy greenhouse booth of heat accumulation function.

Background technology

Human utilization to solar energy is of long duration, and the invention of various coating for selective absorption and heat preserving and insulating material so that people can utilize solar energy efficiently, is used for providing domestic hot water and building and heating.But in the agricultural greenhouse field, utilize the level of solar energy still lower, substantially be confined to receive passively solar radiation.If can absorb on one's own initiative the heat in solar energy and the daytime greenhouse, and heat is stored, be used for the greenhouse heating at night, will greatly improve the production efficiency of solar energy greenhouse and utilize level.

In recent years, China's facilities horticulture engineering develops rapidly, and various agricultural greenhouse scales constantly enlarge, and the area of agricultural greenhouse has accounted for first place, the world.Yet traditional greenhouse by solar heat and the application of plastic tunnel exist great deficiency.For example, in the winter of China's most area, the temperature in the daytime greenhouse by solar heat is very high, often surpasses plant growth temperature required, and the heat that has more often is wasted; And the frequent freezing or obstruction plant growth of the low temperature at night.In order to satisfy the requirement of plant growth at night, must adopt traditional energy such as hot-blast stove etc. is greenhouse heating.This method has not only increased production cost, and contaminated environment.The solar energy greenhouse solution of the warm heat accumulation of at present existing several active confession, but still have many technology and Cost Problems.

(application number: 200820103491.2) propose to arrange solar water heater and attemperater in the greenhouse, utilize water tank to store the hot water of heating daytime, night is to greenhouse heating for patent " solar heat-preservation formula greenhouse ".But the sensible heat heat storage capacity of water is large not, needs a large amount of volume retainings, high cost, and also there is leakage problem in water circuit.

Patent " active mode heat collection and thermal storage system for solar energy greenhouse " (application number: 200810236220.9) propose a kind of active solar energy agricultural greenhouse in conjunction with solar air heat collection and soil thermal storage, the method solar thermal collector need be arranged in both sides outside the greenhouse, need take larger area.

Patent " heat accumulation type solar greenhouse " (application number: 200820211843.6) propose in greenhouse roof solar energy air heat collector to be installed, the heat accumulation tank of in-built gravel is set in kind of bed soil horizon bottom, utilizes hot-air transferring heat between heat collector and heat accumulation tank.But greenhouse roof needs printing opacity, the solar thermal collector area is installed limited, and path that hot-air is walked is long, and thermal losses is larger.

Summary of the invention

In order to store greenhouse by solar heat unnecessary heat on daytime, discharge at night, to regulate the temperature at greenhouse daytime and night, make the variations in temperature in greenhouse more meet the growth needs of crop, the following technical scheme of special proposition:

The present invention goes out a kind of heat-storage solar energy greenhouse, this greenhouse structure includes but not limited to: rear wall of greenhouse, top, greenhouse, high temperature membrane, pillar and heat accumulation part, wherein heat accumulation partly is placed in rear wall of greenhouse, and its structure comprises: blower fan, pipeline, air outlet, heat-insulation layer, transparent cover plate, endothermic tube and heat accumulating.Endothermic tube is the Circular Thin metal tube, and the Length Ratio rear wall of greenhouse is short 20 centimetres, and outer surface is coated with coating for selective absorption, and heat accumulating is contained in the endothermic tube, and sealed at both ends.Heat accumulating adopts the phase-change heat-storage material of fusing point about 30 ℃.The endothermic tube two ends are separately fixed in the heat-insulation layer, and a plurality of endothermic tube erects along rear wall of greenhouse and put side by side, place 7 to 10 for every meter.Heat-insulation layer and transparent cover plate surround a cavity, coat some endothermic tubes, and its length and rear wall of greenhouse are isometric, and heat-insulation layer upper end has an air inlet every 2 to 3 meters, and the lower end has an air outlet accordingly, and air outlet is connected to pipeline and blower fan.

Adopt this technical scheme, can utilize the sunshine area on the wall behind the greenhouse by solar heat, the storage compartment heat plays the effect of regulating day temperature, starts blower fan night and utilizes air that the heat that stores is derived, and supplies with greenhouse by solar heat, promotes nocturnal temperature.

Below in conjunction with accompanying drawing, the invention will be further described.

Fig. 1 is the section structure schematic diagram of this device.

Fig. 2 is this device heat accumulation part schematic diagram.

Fig. 3 is this device heat accumulation part A-A profile.

The position of marking is respectively among the figure: 1, blower fan; 2, pipeline; 3, air outlet; 4, transparent cover plate; 5, heat-insulation layer; 6, endothermic tube; 7, heat accumulating; 8, rear wall of greenhouse; 9, top, greenhouse; 10, high temperature membrane; 11, pillar; 12, air inlet.

Embodiment

Below in conjunction with accompanying drawing, embodiments of the present invention are described further.

The coating for selective absorption that daytime, endothermic tube 6 outsides were coated with converts solar energy into heat energy, and the heat accumulating 7 of endothermic tube 6 inside undergoes phase transition heat absorption, and heat is stored.When nocturnal temperature was reduced to set point of temperature, blower fan 1 started, and air is flowed into from air inlet 12, along endothermic tube 6 surface heat absorptions, heat accumulating 7 phase transformation heat releases.Hot-air through pipeline 2, enters greenhouse by solar heat from blower fan 1 from air outlet 3.
