Description
Technical field
The invention belongs to building energy conservation and field of renewable energy resource utilization, and in particular to a kind of solar water heating system sleeve pipe
Formula phase-change energy-storage water tank device and method.
Background technology
As the continuous improvement of living standards of the people and the demand of building energy conservation increasingly increase, solar energy heating utilization becomes
One of degree of commercialization highest, the most common technology of application in new and renewable sources of energy.One kind of solar energy heating utilization
Important form is solar water heating system.Heat exchanger is whether there is by solar water heating system, can be divided into direct-type system and indirectly
Formula system two types.Direct-type system refer to heated in collecting system after water be supplied directly to user；Indirect type system
System refers to and is provided with heat-exchange device between collecting system and heating system, the working medium of collecting system after heating, by heat
Switch transfers heat to heat storage water tank.The solar thermal collector of indirect type solar water heating system is usual with heat storage water tank
It is detached, i.e., the heat-carrying cycle fluid in solar thermal collector is under the dynamic action of water pump by circulation pipe in heat storage water tank
In directly water is heated.
Regular solar heat storage water tank is placed in residential housing can take more space.As urban population is intensive, room
The high enterprise of valency, quantity of heat storage is big and the less solar heat storage water tank of volume is always what market was expected.The heat accumulation of phase-change material is special
Property provides solution route for this expectation.The phase-change material latent heat that can be used for solar heat storage water tank reaches 170kJ/kg left sides
The right side, water storage equal heat quantity will need the quality of 180 times of phase-change materials.Its ultimate principle is the solar charging timesharing on daytime,
Phase-change material in the water one side heating water tank in hot one side heating water tank that solar thermal collector is collected, at night,
The hot water of water tank is continuously replenished tap water using after, and water temperature constantly reduces, now phase-change material release heat of fusion, heats water.
The heat accumulation characteristic of phase-change material provides solution route for this expectation.Typically there are following three kinds of methods.One be by
Phase-change material makes becomes tabular, is inside affixed on the inner surface of water tank；Two is to be encapsulated as phase-change material spherical, is placed in water tank；
Three is in water tank to arrange pipeline, and phase-change material is encapsulated in pipeline.These ways are that phase-change material occupies water tank capacity,
Effective water-holding quantity is reduced, while heat exchange area is also less, causes storage except heat is little, heat accumulation exotherm rate is slow, and effect is bad.
Patent documentation CN201903201U discloses a kind of phase-change energy-storage water tank.The cisten mechanism is packaged with phase using multiple
