Solar Simulator

The EN13203-3 requires a 24 hours "solar cycle" to be performed in combination with tapping cycles on the sanitary circuit, in order to test the performance of hot water production by solar supported boilers. During the solar cycle a predefined amount of energy or of water having a predefined outlet temperature has to be supplied to the sanitary storage tank, simulating the different amount of energy/temperature supplied by a real solar collector during a day.

A solar collector simulator is a device delivering water, with these variable features, instead of a real solar collector.

Our solar simulator has a structure in aluminium profiles that includes the hydraulic section and a cabinet with the electronics. The hydraulic section includes a small tank fitted with electric resistances, a circulating pump, a heat exchanger, three temperature probes, a flow rate transducer, some automatic and manual valves.

The thermal power of the Solar Collector Simulator (SCS) is produced by a 4KW electric resistance of 4KW, single phase; different powers are available under request.

The circulating pump produces a continuous flow in the SCS circuit. The warm water flow can be switched to the sanitary tank or to a bypass: in this case a closed loop circulation happens. This allows the temperature of the water in the SCS circuit to be kept under control even during the intervals where no energy has to be transferred to the sanitary water; in this way the SCS simulates the real solar collector temperature also in the periods when it's not delivering energy. When energy is transferred to the sanitary tank, the flow rate and temperature measures allow the calculation of the relevant power and energy.

In the SCS circuit a heat exchanger is included; its secondary circuit has to be supplied by cold water. The software can open the flow on this side of the heat exchanger when the temperature of the water in the SCS circuit has to decrease. The minimum level of the temperature in the SCS circuit cannot, obviously, be less that the one of the cooling water.

The electric cabinet in the SCS includes the electric supplies for all the electric elements in the bench, including the pump, the valves and the transducers.

The electronic section is made up by electronic modules Ethernet connected to a control PC.

The SCS is made to be an add-on of a main EN13203 bench.

labSOFT - software for lab activities

labSOFT is the software developed by Microplan for the lab and R&D activities, based on Labview by National Instruments, a very powerful platform laboratory-oriented.

12 good reasons for choosing labSOFT

  1. operational testing conditions automatic reaching and keeping
  2. parameters from database
  3. automatic measurements and calculations
  4. automatic compensation of transducers errors based on calibration curves [learn more]
  5. temperature measurement redundancy
  6. calculation process fully traceable on screen 
  7. formula and partial results visibles 
  8. data logging of all the measurements acquired during the test 
  9. automatic reporting
  10. "free test" function with active synoptic (R&D mode)
  11. easy to learn
  12. easy to use

1. Synoptic feature

This features allows the operator to drive the test bench with a simple click on the mouse as every active component of the bench is available. The operator can also set the parameters for the PID control of the water flow rates. All the instant values are displayed on the screen next to the related transducer.

2. Chart feature

The operator is free to decide which of the available measurement transducers (ex. water flow rate, pressure, etc.) he wants to be displayed. Whenever he wants the operator can start logging the selected measures.

3. X-Y graph feature

This feature allows the operator to select two measures and get them displayed on a X-Y graph. This is different from the previous "2. Chart feature" where on the X axis the time is always displayed. A report, including a graph of the test executed, can be generated.

4. Automatic tests

This sections is about all those tests which refer to a specific standard such as for instance EN 483, EN 677, EN 26, EN 13203, ASHRAE 103 etc. In this case the operator just have to select the test to be permormed and then the bench will automatically reach the steady conditions and after a prompt from the operator will execute the test automatically. All the relevant measures are displayed throughout the test and the operator is free to select those he wants to be displayed. All selected measures are logged and available for statistical elaborations and a test report is finally produced.

5. Data analysis

This feature is very useful during R&D operations as the tester can promptly check the results of the ongoing tests.

6. Utilities and settings

  • Database of the different gases with related characteristic values
  • Editor of calibration points
  • Troubleshooting diagnostic panel
