Equipment Introduction

KTE-7000SR (Solar Radiation Energy Experimental Device) is an experimental device based on the principle of solar radiation energy. It measures the amount of radiation energy reflected by reflectors of different materials using an artificial sun, and is configured to learn the principle of solar radiation energy by storing and analyzing data using a program.
By using the unique emissivity of an object, objects with different emissivities can be installed in each room at various angles to compare and analyze the temperature change and the difference in emissivity according to the angle at which the object receives light. It is also possible to analyze the change according to the angle of incidence by adjusting the angle of the artificial light source (halogen lamp).
KTE-7000SR is a device that helps you easily understand the principle of solar radiation energy and the overall content of solar power generation and solar thermal systems.

Equipment Characteristics

This experimental equipment was designed to allow experiments and practice on the basic principles of solar radiation energy, heat accumulation and heat transfer.
Experiments can be conducted using artificial sun and natural solar heat, and the temperature inside the insulation box can be maintained at a constant level.
Since materials with different emissivities are installed inside the insulation box and the incidence angles are designed differently, temperature and radiation heat can be measured according to the settings, allowing for efficient experiments.
It is designed to allow experiments and practice using materials with different emissivities, allowing for understanding not only the principles of solar radiation energy but also the emissivity of materials.
With the artificial sun installed in this equipment, it is possible to test the amount of radiation energy controlled according to the distance and incidence angle.
When using the artificial sun, experiments measuring the temperature change of the light source are possible through the temperature sensor attached to the halogen lamp light bulb used as a heat source.
Experiments comparing the amount of radiation heat transfer according to the emissivity of the material inside the insulation box are possible.

Components of the Equipment

The solar energy collector effectively collects the radiant energy from the Sun. It consists of a clear cover, heat absorber plate and insulator.

The thermal storage tank stores heat collected from the collector so that the heat can be converted into a useful energy later.

Fan type heat exchanger role is that sending warm air into the room by release boiling water on solar collector into the constant temperature air.

This device is for release heat source through exchanging between cold air and warm water which was supplied from heat storage or boiler system.

The heat exchanges high temperature collected in the heat collector with the low temperature inside the heat tank. The primary heat source is the heat collecting medium, which uses antifreeze substance to prevent freezing in winters, and the secondary heat source is water, which is used as hot water and heating water.

The hot water pump functions as a driving gear that circulates the water through pipes in the solar hot water boiler system.

The pressure pump supplies water from the make-up water tank to system pipes when there is a lack of circulating water inside the solar hot water boiler system.

◈ Operation Principles of Active Solar System ◈

Heat collecting process:

① Receive heat energy from the Sun, ② Temperature rise in heat collector, ③ Start operating Pump1 and Pump2, ④ Heat collecting medium enters T2 (input of heat collector), passes through T14 to absorb solar energy, which is emitted through 43 (output of heat collector) then enters the heat exchanger. Here, the heat energy is transferred through heat exchanges with the heat storing medium.

Heat storing process:

① Pump1, heat collecting convection pump, links with Pump2 to run it ② The thermal medium stored in thermal storage tank passes through T5 (output of heat tank), passes through the heat exchanger and enters T4 (input of heat tank) ③ Here, the heat energy is absorbed from the heat collecting medium and transferred to the top part of the heat tank

Heat processing:

① If temperature of T13, internal temperature of chamber, is lower than the setting value, ② run Pump3. ③ The thermal medium stored in the heat tank passes through a distributor and enters T8 (T10). Then it heats up the chamber through the heat exchanger and returns to the heat tank through T9 (T11)
