In conjunction with accompanying drawing and with reference to the preferred embodiment of the utility model; Those skilled in the art can understand the application's further open, purpose, advantage and aspect better; These given accompanying drawings and embodiment are for illustrative purposes, rather than the protection domain of the utility model is limited.
The specific embodiment
In the winter time, when outdoor temperature arrives subzero, bring into operation from the gravity heat pipe; Absorb heat in the water of heat pipe evaporator section 3 from ice bank 1; Liquefied ammonia evaporation in the pipe imports to ammonia steam in the heat pipe condenser section 3 liquefied ammonia evolution of heat in heat pipe condenser section 3 through heat pipe tube connector 5; Change liquid state again into, flow back in the heat pipe evaporator section 3 through heat pipe tube connector 5.Liquefied ammonia is this automatic phase transition process in heat pipe, and constantly the heat with water in the ice bank 1 takes in the atmosphere, gradually water is all become ice.
Make water become the process of ice according to evaporator section 4 from the gravity heat pipe; Ice along the outer wall of ice bank 1 to outgrowth; Icicle increases to 30 centimetres of needs of diameter time in about 1 week, and after this, the icicle growth is comparatively slow; That is to say that the speed of the phase change cold-storage through water in the ice bank 1 will be very slow.
The utilization of present technique scheme is striden and is iced the mode that cold accumulating pond 1 combines with ground pipe laying 2 season, when the diameter of icicle reaches or during near 30 centimetres, the water of the pipeline in the ice bank 1 with 0 ℃ is input in the ground pipe laying 2 through water pump; Through the heat exchange of ground pipe laying 2 with soil; The temperature of soil is reduced, can the cold that import from air through heat pipe in the ice bank 1 be shifted and store in the soil; Poor efficiency stores up cold mode in ice bank 1 thereby make, and changes the efficient storage through soil into.In addition, the volume of ice bank 1 is fixed, and stored cold also is limited, but through with the combining of ground pipe laying 2, can store more cold in a same winter.
Through with the combining of ground pipe laying 2, hold pond 1 and can store more cold than original traditional season ice of striding.
With reference to accompanying drawing 1, when ice bank 1 ice storage when icicle grows into 30 centimetres, start ground pipe laying 2, the cold in the ice bank 1 is imported in the soil, store more cold energy through soil.Concrete implementation procedure is following:
Open valve 9,17,12,11,10 is opened water pump 8, and ice bank 1 is connected with ground pipe laying 2.Water pump operation is got to the chilled water in the ice bank 1 in the ground pipe laying 2, carries out heat exchange with soil, and the temperature of soil is reduced.When daytime temperature is higher, through with the circulation of not cutting off the water supply of ground pipe laying 2,1 ice can constantly melt in the ice bank; At night; Close the water circulation with ground pipe laying 2, can reserve sufficient recovery time to soil, also can be through the operation of heat pipe; Again airborne natural cold-energy is imported in the ice bank 1, make the ice storage in the ice bank 1 also return to the preceding level of ground pipe laying 2 operations.
When need external cooling summer, can use ice bank 1 also can use ground pipe laying 2 external coolings.During the external cooling of ice in using ice bank 1, an Open valve 19,13,14 is opened centrifugal water pump 7, through plate type heat exchanger 6 cold is given outside ductwork, supplies toward air conditioning terminal; When using the external cooling of ground pipe laying 2, an Open valve 18,17,12,15,16 is opened centrifugal water pump 8, when leaving water temperature is lower than 7 ℃, and the direct past air conditioning terminal of confession.
The utility model can increase the storage capacity of natural cold-energy.Stride and ice season combining of cold-storage ice bank 1 and ground pipe laying 2, adopt a same cover from the gravity heat pipe, can realize simultaneously striding and ice cold-storage and soil ice cold-storage season, the capacity of looking buried guard system can increase the storage capacity of natural cold-energy greatly.
The tradition soil thermal storage need dispose jumbo chilled water cushion space, strides and ices the cold-storage ice bank season and just in time can satisfy the demands.The soil storage is cold works in coordination with the ice bank ice storage in time, and two systems combine, and do not increase extra investment, and economic benefit is better.
Although the exemplary embodiments to the utility model is illustrated; But obviously those of ordinary skill is appreciated that; Under the situation of spirit that does not deviate from the utility model and principle, can change, its scope claims with and equivalent in limit.
