Absorb a large amount of heat in greenhouse 19；On the other hand, the underground water extracted through high-pressure pump 7 is by supervisor 8, the end of branch pipe 16
Outlet pipe 20 is imported afterwards, and finally flows into underground water, the outlet pipe 20 successively spiral cold-finger 22 in water cooled system 14,
And the low temperature of underground water is discharged by the peripherad high temperature air of spiral cold-finger 22, the air themperature around condenser pipe drops
It is low.
The electric screen robling machine 13 in blower system starts at this time, slowly the film of 19 two sides of greenhouse is driven to roll film, from
So leak informaton, while the air blower 15 in blower system blasts external air, the air blasted passes through water-cooling system 14, by water cooling
The cold air that the Cryogenic air come out around spiral cold-finger 22 in system is blasted inside greenhouse 19, while being blasted
The micro- mist for blowing the injection of micro- mist system, accelerates the evaporation of micro- mist, and eventually by the air-introduced machine 12 of 19 other side of greenhouse by wet sky
High-temperature gas in gas and canopy detaches greenhouse 19, reaches cooling, dehumidifying, changes CO in greenhouse2The technical effect of concentration.
Outer screening while micro- mist system, water-cooling system 14 and blower system synchronous collaboration cool down, in external sunshade system
Also synchronous averaging, drive sunshade net 11 stretch sunshade, reach the technical effect of auxiliary temperature-reducing positive electricity machine 10.
It is that micro- mist system is closed when temperature is too low in greenhouse 19, water-cooling system 14 is opened, and is only taken out by high-pressure pump 7
The higher underground water of temperature raising degree finally imports underground through supervisor 8, outlet pipe 20, spiral condensation 22, forms ground water circulation.Only
Using the temperature resource of underground water, heat is distributed by flowing through condenser pipe；The air blower 15 in blower system works simultaneously, will be warm
The air spent around higher condenser pipe uniformly blasts inside greenhouse 19, increases the temperature in greenhouse 19, reaches
The technical effect heated.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
Those familiar with the art in the technical scope disclosed by the present invention, can easily think of the change or the replacement, and should all contain
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be based on the protection scope of the described claims.
