Abstract
The utility model provides an evacuated type solar water heating system, solar collector, buffer tank, heat exchanger and circulating pump pass through circulation pipeline circulating connection in proper order, and the heat exchanger is as for heat storage water tank inside, buffer tank sets up in the high position that is less than solar collector, and its inner space keeps the intercommunication with the atmosphere. Can not satisfy the circulating temperature of settlement when the continuous reduction of solar collector's temperature, the circulating pump bring to rest, water because solar collector by the evacuation, can realize preventing frostbite, has also avoided trading the overheated emergence of hot working medium because the action of gravity falls after rise to buffer tank. Owing to does not adopt anti -icing fluid, has just eliminated anti -icing fluid yet and leaked the environmental hazard that brings. Because circulation circuit open, just need not to adopt safety devices such as relief valve, expansion drum in addition. System safe and reliable, convenient maintenance.
Description
Technical field
This utility model relates to a kind of solar water heating system, particularly to a kind of emptying type solar heat water system
System.
Background technology
Common detachable solar hot-water heating system is as it is shown in figure 1, solar thermal collector 1 and heat storage water tank 4
Separating, heat drives heat-exchange working medium by water pump 3, transfers heat to heat exchanger 5 by circulation line 2,
Within heat exchanger 5 is placed in heat storage water tank 4, finally transfer heat in the water within heat storage water tank.So
Move in circles, it is achieved collection thermal cycle.The advantage of this solar water heating system is: heat collector separates with water tank,
Can be by abundant for heat collector and Integration of building, water tank location is flexible.Water in water tank, with certain pressure, is washed
Bathing comfortable, mixed water lower water temperature is convenient.
But owing to i.e. hot loop is closed, have the disadvantage in that
1, for a long time without hot water, when, heat collector internal working medium is overheated, and heat collector is caused damage；
2, it is constantly filled with working medium in heat collector, has frozen block risk winter, need for this to irrigate anti-icing fluid, and prevent
Environment can be worked the mischief by the leakage freezing liquid；
3, need to arrange the safety devices such as expansion drum, relief valve in collection hot loop；
Because of High Temperature High Pressure, system failure rate is higher, and maintenance cost is higher.
Utility model content
For solving above-mentioned technical problem, the purpose of this utility model is: provide a kind of Novel separated type sun
Energy hot-water heating system, is arranged by emptying, it is to avoid the detachable solar hot-water heating system that existing collection hot loop is closed
Potential safety hazard.Security of system, easy and simple to handle, failure rate is low.
For achieving the above object, this utility model be the technical scheme is that
A kind of emptying type solar water heating system, it is characterised in that include solar thermal collector, circulation line,
Circulating pump, heat storage water tank, heat exchanger and buffer tank, wherein:
Described solar thermal collector, buffer tank, heat exchanger and circulating pump are by described circulation line successively
Circulation connects, and described heat exchanger is as heat storage water tank inside；
Described buffer tank is arranged below the height and position of solar thermal collector, and its inner space and air
Keep connection.
Described emptying type solar water heating system, wherein, aerofluxus is passed through in the inner space of described buffer tank
Valve keeps connecting with air.
Described emptying type solar water heating system, wherein, described buffer tank is positioned at described heat storage water tank
Outside.
Compared with prior art, the utility model has the advantage of of technique scheme is used: system can be arranged
Sky, prevents heat collector internal working medium overheated.Collection soft circulation circuit, without using anti-icing fluid, can realize antifreeze,
Avoid the risk of leakage of chemical substance.System need not the safety devices such as relief valve, expansion drum, non-pressure
Safe and reliable to operation.The failure rate is low of system, easy to maintenance.

Detailed description of the invention
Further describe this utility model below in conjunction with specific embodiments and the drawings, advantage of the present utility model and
Feature will be with describe and apparent.
As shown in Figure 2, for this utility model one emptying type solar water heating system, by solar thermal collector 1,
Circulation line 2, circulating pump 3, heat storage water tank 4, heat exchanger 5, buffer tank 6 forms.Wherein, the sun
The import of energy heat collector 1 is connected with circulating pump 3 by circulation line 2, and circulating pump 3 is by circulation line 2
Being connected with heat exchanger 4, the other end of heat exchanger is connected with buffer tank 6 by circulation line 2, buffered water
The copper pipe circulation line 2 of case 6 is connected with the outlet of solar thermal collector 1.Described buffer tank 6, is arranged
At the height and position less than solar thermal collector 1, and its inner space is kept by air bleeding valve and atmosphere.
Heat exchanger 5 is placed in the water of heat storage water tank 4 internal reservoir.
When solar irradiation is sufficient in the daytime, solar thermal collector 1 absorbs solar energy temperature and raises, when its temperature
Degree is higher than the certain difference of heat storage water tank 4, and circulating pump 3 starts, and drives current by solar thermal collector 1, inhales
Receive the water of heat by, after solar thermal collector 1, flowing in buffer tank 6.Circulating pump 3 continuous running,
Water in buffer tank 6 is flowed continuously through heat exchanger 5 by suction, then flows to solar energy collection through circulating pump 3 promotion
Hot device 1, so moves in circles, and water collects heat from solar thermal collector 1, is passed by heat again at heat exchanger 5
Pass the water within the more lower heat storage water tank of temperature 4, it is achieved the collection of heat stores.When solar energy collection
The temperature of hot device 1 constantly reduces the circulating temperature that can not meet setting, and circulating pump 3 is out of service, water due to
Action of gravity falls after rise to buffer tank 6, and the volume of certain buffer tank 6 can accommodate backflow through design
Water.Owing to solar thermal collector 1 is drained, it is possible to achieve antifreeze, it also avoid heat-exchange working medium overheated
Occur.Owing to being provided without anti-icing fluid, also eliminate the need for anti-icing fluid and leak the environmental hazard brought.Additionally due to
Closed circuit is open type, is no need for using the safety devices such as relief valve, expansion drum.Security of system is reliable,
Convenient maintenance.
Described above it is merely exemplary for this utility model, and nonrestrictive, ordinary skill
Personnel understand, in the case of the spirit and scope limited without departing from claim, can many modifications may be made,
Change or equivalence, but within falling within protection domain of the present utility model.
