Description
Technical field
The utility model belongs to solar-heating technical field, is specifically related to a kind of solar water unit.
Background technology
Solar energy, owing to having aboundresources, local use, the advantage such as clean and renewable, widely uses at present in a lot of fields.Solar water is an application of solar energy achievement, and it, with advantages such as environmental protection, safe, energy-conservation, health, has won rapidly the favor of consumers in general.Solar water is mainly using solar water heater as a large industry, but solar water heater take family as unit, uses dispersion, and install trouble and be unfavorable for layout, the resident family especially for intensive residential building is difficult to install and use.Relatively large, large-sized solar central hot water supply system can solve the situation of intensive residential building resident family, hotel, school, bath center large discharge use hot water preferably.But because solar energy changes throughout the year, and with little or no, and therefore, solar water often attaches auxiliary heating mode, and common hot water normal-pressure boiler is one wherein.Hot water normal-pressure boiler communicates with air due to boiler openings, water in boiler participates in hot water circuit and heating directly, easily causes boiler dehydration, oxide etch, backflow fault etc., but also will cause the pressure loss of hot water circuit, hot water circuit pressure can not be utilized, add power consumption.
The system schema that solar water heating system is general is the mode of vacuum heat collection pipe+storage tank, can play effect of energy, but cannot temperature control.Existing solar water heating system, under daylight abundance and not enough situation, water temperature alters a great deal, and cannot send water by constant temperature; And at rainy weather, hot water temperature's requirement can not be met.
Utility model content
The utility model provides a kind of solar water unit, and setting can realize temperature controlled mechanism, the satisfactory constant-temperature hot water of continual and steady supply.
The utility model solves the technical scheme that its technical problem adopts: solar water unit of the present utility model, comprise solar thermal collector, heat collection water tank, constant temperature water tank, steam heat-exchanging unit, outlet pipeline connects solar thermal collector, heat collection water tank, constant temperature water tank and steam heat-exchanging unit successively; Also comprise return duct, connect steam heat-exchanging unit, constant temperature water tank, heat collection water tank and solar thermal collector successively; Outlet pipe between heat collection water tank and constant temperature water tank and return duct install water pump respectively, the return duct between heat collection water tank and solar thermal collector installs water pump, water pump installed by the outlet pipe between steam heat-exchanging unit and constant temperature water tank; Steam heat-exchanging unit is arranged air inlet pipe and escape pipe.
Constant temperature water tank arranges drainpipe and feed pipe simultaneously.
Increase steam heat-exchanging unit to be connected with constant temperature water tank, at rainy weather, when solar thermal collector is inoperative, automatically open steam heat-exchanging unit heat;
When heat collection water tank and constant temperature water tank there is the temperature difference (temperature difference >=5 DEG C) and constant temperature water tank lower than design temperature time, water pump is between the two opened automatically, and the aqueous phase between two water tanks is mixed to mutually when constant temperature water tank temperature reaches setting value and stops; In the situation of deficiency at overcast and rainy or other at sunshine, when heat collection water tank and constant temperature water tank water temperature are all lower than constant temperature water tank desired temperature, open steam heat-exchanging unit, open heating mode, to the water heating in constant temperature water tank, make the water temperature in constant temperature water tank constant.
Accompanying drawing explanation
Fig. 1 is solar water set structure schematic diagram of the present utility model.
In figure: 1. solar thermal collector; 2. heat collection water tank; 3. constant temperature water tank; 4. steam heat-exchanging unit; 5. outlet pipe; 6. return duct; 7. water pump; 8. air inlet pipe; 9. escape pipe; 10. drainpipe; 11. feed pipes.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment 1
See Fig. 1, solar water unit of the present utility model, comprises solar thermal collector 1, heat collection water tank 2, constant temperature water tank 3, steam heat-exchanging unit 4, and outlet pipe 5 connects solar thermal collector 1, heat collection water tank 2, constant temperature water tank 3 and steam heat-exchanging unit 4 successively; Also comprise return duct 6, connect steam heat-exchanging unit 4, constant temperature water tank 3, heat collection water tank 2 and solar thermal collector 1 successively; Outlet pipe 5 between heat collection water tank 2 and constant temperature water tank 3 and return duct 6 install water pump 7 respectively, the return duct 6 between heat collection water tank 2 and solar thermal collector 1 installs water pump 7, water pump 7 installed by the outlet pipe 5 between steam heat-exchanging unit 4 and constant temperature water tank 3; Steam heat-exchanging unit 4 is arranged air inlet pipe 8 and escape pipe 9.
Constant temperature water tank 3 is arranged simultaneously drainpipe 10 and feed pipe 11.
Increase steam heat-exchanging unit 4 to be connected with constant temperature water tank 3, at rainy weather, automatically open steam heat-exchanging unit 4 when solar thermal collector 1 is inoperative and heat;
When heat collection water tank 2 and constant temperature water tank 3 there is the temperature difference (temperature difference >=5 DEG C) and constant temperature water tank 3 lower than design temperature time, water pump 7 is between the two opened automatically, and the aqueous phase between two water tanks is mixed to mutually when constant temperature water tank 3 temperature reaches setting value and stops; In the situation of deficiency at overcast and rainy or other at sunshine, when heat collection water tank 2 and constant temperature water tank 3 water temperature are all lower than constant temperature water tank 3 desired temperature, open steam heat-exchanging unit 4, open heating mode, to the water heating in constant temperature water tank 3, make the water temperature in constant temperature water tank 3 constant.
Thermostatted water is discharged by drainpipe 10 and is used, and by feed pipe 11 to water filling in whole unit, enters solar thermal collector by return duct 6.
