Choice is the use of plate type water heater (thermal performance report from Switzerland SPF testing center web site
Release test report).
As is known to all, water heater efficiency equation based on different reference area, the water heater efficiency equation
Each parameter is different, the difference is larger. As a manufacturer, usually need to be given total surface of the water heater
Product (area), lighting area, heat absorber area of three data, for the selection of the design. The base
In heat absorber area, general vacuum tube water heater is a little high, but because of its structure, its total surface
Product generally, based on the total area, plate type water heater is the best effect, the instantaneous efficiency
High above 50%, the total area of the water heater determines the number of water heater can be installed, so the comparison
, to achieve the same effect, flat water heater needed quantity minimum, the best return on investment.
Plate type solar water heater and vacuum tube solar water heater system
Thermal efficiency of solar water heater: tablet is higher by 52.5%, 47% low vacuum tubes.
The solar water heater price: tablet is higher, low vacuum tubes.
Solar energy water heater pressure: plate type can be confined, easy to make shower, vacuum tube socket
Pressure, easy to broken.
Solar energy water heater furring: flat type water heater drainage, not easy scaling, vacuum tubes
Bottom sealing, easy to scale, lower thermal efficiency.
The solar water heater durability: plate type high strength, durable, don't tube, hail
Have a flat glass protection, vacuum tube will touch bad, water supply, hot tube added cold suddenly
Water and explosive tube, hail damage valve itself directly.
Average thermal efficiency value of 1994-1997 national test. Plate type thermal efficiency is high
Reason: the vacuum tube heating surface is not completely, but also set aside for installation between between tube and tube
Gap.
Can be seen in the above comparative analysis, flat plate solar water heater than the vacuum tubes of the sun
Can water heater is more advanced, with the development of economy and the demand of the energy conservation, the sun in our country
Can water heater will gradually to the plate type solar water heater, reached the international advanced solar
Energy-saving water standards
1.1 flat system
To develop energy-saving building at the same time, as the global flat-panel solar gradually replaced vacuum tubes
Solar energy, become a part of energy saving building core. Flat solar collector good appearance,
Rational layout, is the realization of the weight of solar energy and the building integration.
Plate solar collector is a kind of absorption of solar radiation energy and transfer heat to the working medium
The device, it is a special kind of heat exchanger, collector of working medium and the distance of the sun
For heat exchange. Flat-plate solar collector is a type of solar collector. is
By the heat absorbing plate core, shell, transparent cover plate, insulation materials and related components. The added
After circulation pipe, heat preservation water tank, namely become can absorb solar heat, make the water temperature to rise.
1.1.1 plate solar collector works
The basic working principle of plate solar collector is very simple. In a nutshell, the sunshine through
A transparent cover plate exposure to the surface coated with absorbing layer of endothermic body, most of the sun radiation
For absorber absorbed and transformed into heat energy, and to working medium in the fluid channel. In this way,
From the bottom of the collector inlet cold working medium, is heated by solar energy in the fluid channel, temperature one by one
Gradually rise, heated hot working medium, with useful heat energy from the top of the collector export, storage
Into the water storage tank for use, is the useful energy gain. At the same time, due to the endothermic body temperature rises
High, dissipating heat to the environment through the transparent cover plate and shell, constitute the flat plate solar collectors
Heat loss.
1.1.2 endothermic board
Endothermic board is flat solar collector to absorb solar radiation and heat transfer within the working medium
Heat transfer components, which is basically a flat shape.
The structure of 1.1.2.1 endothermic board
On the flat shape of endothermic board, usually decorate a row tube and manifold. Exhaust pipe is refers to the suction
Hot plate parts vertically and fluid channel; Header is refers to the heat absorbing plate at both ends up and down horizontally
Connecting several row tube and a fluid channel parts. Endothermic board has a variety of materials, there is
Copper, aluminum alloy, copper aluminum composite, stainless steel, galvanized steel, plastic, rubber, etc. Endothermic board has
The following main structure form.
(1) tube plate. Tube-sheet heat absorbing plate is a combination of exhaust pipe and plate at a certain way
Pick up a heat absorption bands, and then to set up and down tube welding into a collector. This is at home and abroad
Using common type of endothermic board structure.
Solar energy research institute in wuhan city in 1986, one has the international advanced imported from Canada
Levels of copper aluminum composite solar production lines, make up a new flat collector technologies in China
The steps of the. The technology is a copper pipe between the two aluminum plate hot rolling together, however
After it with high pressure air blow molding. Article copper aluminum composite sun: the advantages of high thermal efficiency,
Hot rolling to metallurgical bonding between copper and aluminum plate, and no thermal resistance; Water clean, too
Yang contact water part of the article is copper, won't corrode; Ensure the quality, the whole production process
Now the mechanization, to ensure product quality; Compression capability is strong, the sun is to use high pressure air
The blow molding.
In recent years, the copper heat absorbing plate is gradually rise in our country, it is through the brass and copper
High frequency welding or ultrasonic welding technology to connect together. All copper endothermic board has copper aluminum composite too
Yang article all the advantages: high thermal efficiency, no combined with thermal resistance; Water clean, brass won't be rotten
The corrosion; Ensure the quality, the whole production process to realize mechanization; Compression capability is strong, brass can bear
By high pressure.
