Introducing the Naplopó software

package



Chapters

- Basics of solar energy,

- Goal of the software package,

- Generally about computer calibration,

- Calculation cycles of calibration,

- Figures,

- Set up of the software.

Basic forms:

• Passsive without using any equipment. Design of building is special.

• Active (transform the solar energy to)

Thermal energy Electricity

Solar collector Photovoltaic (PV) module

Utilization of solar energy



4

• Collectors

Equipment of solar thermal system

Air collector

The best positions of collectors in Hungary:

Winter time (dec.-febr.): 76,2°,

Summer time (june-aug.): 18,5°,All year: 43,5°.

Absorber plate

The absorber plate is influenced the performance of the collector. The following properties are required

for the quality of absorber plate:

• High heat sink ability,

• Low heat back radiation,

• Low internal flow resistance,

• Corrosion resistivity,

• Good heat transfer capability of working fluid,

•Temperature resistance.



Aim Determine the usefull energy of the collectors

It is a hard work, because:

-Collectors efficiency are not constant,

-It is depending on the weather.

We need to calibration before replace the solar system installation.

That’s why



• NAPLOPÓ is running under Windows operation. It is developed by a Hungarian

company.

• It can be used for testing solar hot water system and swimmingpool heating too.

• Work with Hungarian meteorology data. The incoming radiation, ambienttemperature, wind flowing, humidity, soil temperature, probability of weather.

•The software is calculating with the variant angle and orientation of solar collectors.

And geometry of sun’s movement.

Generally about computer calibration



Calculation cycles of calibration

There is opportunity to calculate for different terms. Like daily, monthly, yearly or a period.

The software simulate the weather condition.

The results can be seen on figures and compare to the previous result.

Cycles:

- Daily: we can chose the month of the year and day of the week and also the weather condition.

- Monthly: The weater condition can not chose it is simulated by the software.

- Yearly: From 1 jan. to 31 dec. The weater condition and month can not chose.

- Period: We can set a period of the year, like for summer or winter season.



Results from the software:

- Heat of collectors and Sun,

- Efficiency of the system,

- Solar share,

- Heat gain(hőnyereség), - Heat loss,

-Traditional energy.

Type of losses:

• Loss of collectors,

• Loss of circulation,

• Loss of pipline (friction losses between the pipe and water from point to piont)



Temperature of the storage tank.
