Components of the Equipment

7000SB-Solar Energy Collector.png

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

7000SB-Thermal Storage Tank.png

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

7000SB-Modified Inside Building.png

  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.

7000SB-Plate type heat exchanger.png

  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.

7000SB-Hot Water Pump.png

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

7000SB-Pressure Pump.png

  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)
