Concrete operations are as follows:
The hot and cold liquid that construction one is enough large on the ground exchanges casing or pond, i.e. ground boiler 1, on the ground liquid reserve tank 9, to be heated by ground or natural wind, fan blow on (take physics refrigerating method, but not liquefied ammonia or freon refrigeration method).
By large transmission pump 7, little transmission pump 10 and at the refrigerating fluid transmission pipeline 12 be connected, heating fluid transmission pipeline 13 by cooled solution 11, be transported in underground heat pond 20, underground ice cell 23, underground cold water pond 24 by heated solution 14;
By heat, cold exchange, by the U-shaped hot coil be placed in one, U-shaped cooling coil and double helix cooling coil and the warm heat pipe 19 be connected, condenser pipe 21, cold water pipe 22 heat exchange or refrigeration respectively;
Send instruction by each sensor 16, temperature controller 17 that independently the underground confined space-15 li, constant heat storage/room, underground is arranged, the warm heat pipe 19 introduced, condenser pipe 21, cold water pipe 22 are regulated the cold and hot of each constant heat storage/room, underground 15.
In the corresponding large underground ice cell 23 of infrastructure one, underground cold water pond 24, in winter by ground liquid reserve tank 9 and connected pipeline circulating system circulation anti-freezing liquid, the anti-icing fluid of-5 ~-10 degree is transported in underground ice cell 23, water abundant in underground ice cell 23 is made ice;
This part ice at least stores up the cold energy of cold some kilowatt hours, namely utilize winter natural cold environment that anti-icing fluid is reduced to lower temperature, then by piping loop, these anti-icing fluid are transported in underground ice cell 23---water in ice cell is made abundant ice---storage of cold;
Then, also can by pipe water cycle---the cold water in 24 li, underground cold water pond to be transported in constant heat storage/room in steel pipe shelf 25, the effect that cold energy reaches cooling is discharged by this steel pipe shelf 25 conducting cold water or frozen water mode---because steel pipe shelf 25 distribute extensively and evenly, area is also large, therefore, thermoregulation effect rapidly and evenly, does not stay dead angle.
Simultaneously, the steel pipe of these steel pipe shelf 25 is installed abundant fire hydrant 18, once in constant heat storage/indoor breaking out of fire, connects this fire hydrant 18 by fire hose immediately, aligning point of origin sprays, and has the water of certain pressure in steel pipe shelf 25 and reach the object of fire-fighting.
If, constant heat storage/room, underground needs intensification degree (such as, the temperature of 23 DEG C ~ 25 DEG C is just needed) during ginger nursery, can circulate in above steel pipe shelf 25 higher temperature water and reach intensification object secondly, above steel pipe shelf 25 are upwards extended welding, can back be supported---there is safety supports effect.
This method of temperature control adopts physics, naturally, instead of adopt the mode of underground heating or refrigeration, also reduce and use non-liquefied ammonia or freon, or electric energy, gravity-flow ventilation in the confined space of underground will be reduced bad, easily cause poisonous and harmful, flammable and explosive substance gathers or the limitation of oxygen content deficiency, also can effectively improve simultaneously heat at present, the power consumption of freezing is large, energy consumption efficiency is low, and drawback not environmentally, improves comprehensive utilization of energy rate.
And take on the ground nature heat or refrigeration method, effectively can reduce the unordered development and utilization to underground air, resource, decrease pollution, freeze or add thermogenetic waste gas can again by Cemented filling to floor treatment.Meanwhile, due to cold and hot pipeline, comprising power pipe etc. is all by underground caliber, also serves the effect of insulation.
The above is detailed description and the accompanying drawing explanation of present pre-ferred embodiments; not be used for limiting the present invention; protection scope of the present invention should be as the criterion with claim, and the embodiment of the spirit change similar with it of every this patent protection domain and approximate construction, all should be contained among the present invention.
