Summary of the invention
It is long to the purpose of this invention is to provide a kind of time of preserving energy, and accumulation of energy is big, the method that stores and utilize natural cold-energy that the energy preservation effect is good with save that ground space, cost of use are low, the underground low temperature storage of energy savings.
Technical solution of the present invention is:
A kind of method that stores and utilize natural cold-energy, it comprises the steps:
A, utilize blower fan the cold air more than the ground to be introduced around the body of the Kuku of storage below the frozen soil layer of ground and the air channel of bottom in the season of cold; Be provided with air inlet duct and exhaust passage between air channel and the ground; Cold air makes natural cold storage body such as the earth around the air channel and is built in the underground freezing cold-storage of storage Kuku body, and cold energy is discharged to more than the ground from underground by the air after storing;
B, at the natural cold storage body of freezing earth etc. in warm season be built in that underground storage Kuku body thaws, cold energy is released to the reserve cooling in the bunker.
Use the underground low temperature storage of said method: it comprises the storage Kuku body that is built in below the frozen soil layer of ground; Be provided with insulating layer between the top of storage Kuku body and the ground; Around the body of storage Kuku and bottom is provided with and stores revetment and the river bottom protection that forms the air channel between the body of Kuku separately, is provided with air inlet duct and exhaust passage between storage body air channel, Kuku and the ground.
Technique effect of the present invention is: it is long that this method has the time of preserving cold energy; Accumulation of energy is big; The advantage that the energy preservation effect is good, underground low temperature storage have saves that ground space, cost of use are low, the advantage of energy savings, and it is constant that its temperature keeps easily; Help the fresh-keeping of article, should be widely promoted.
Northern China frozen soil layer in winter reaches about 2 meters of below grounds; The time of thawing fully, its time reached half a year probably in mid-May, and the present invention utilizes natural cold storage bodies such as the north of china in winter earth Chu Leng that freezes; Thaw summer and release cold rule; On the air outlet of storage body exhaust passage, Kuku, air-introduced machine need be set, can also set up air blast again at the air inlet of air inlet duct, introduce cold air underground winter is that air channel earth on every side makes it freezing with the body cooling of storage Kuku; Spring and air channel in summer earth on every side thaw with storage Kuku body becomes low-temperature receiver; Be the article cooling of storing in the body of storage Kuku, it has the cold function of storage, need not waste energy to heat for storing Kuku system cold-peace.
