Basic equipment for digital measured value acquisition, visualisation and evaluation for the heating technology teaching system with renewable energies consisting of:
- 4 precision measuring devices, each with 9 inputs for sensors
- Sensors for recording measured values for temperature, pressure and volume flow
- Notebook with preconfigured measuring programme with graphical user interface
The following measured values can be recorded and visualised in principle at the training stands:
- Training Stand S1: Geothermal heat/floor heating with 3 pipe circuits in
the water tank as source or sink
- Flow and return temperature sensor in the main circuit
- volume flow sensor in the main circuit
- 3 temperature sensors in front of the receiver to check the hydraulic balance
- Training Stand S2: Fan coil as source or sink
- Flow and return temperature sensor in the main circuit
- volume flow sensor in the main circuit
- anemometer sensor at the output of the fan coil to measure the air speed*
- Temperature sensor at the air inlet and outlet of the fan coil
- Training Stand S3: Solar heating with solar simulation
- Radiation sensor in front of the collector as pyrrheliometer
- Training Stand S4: Coupling component with buffer tank, plate heat
exchanger (PHE) and hydraulic switch (HW)
- Flow and return temperature sensor in the main circuit
- 4 temperature sensors at the inputs and outputs on the primary and secondary sides of the PHE or HW
- Training Stand S5: Heat pump with measuring and switching units
- The temperature sensors in the source and sink circuits and in the refrigerant circuit available at the training stand can be supplemented by sensors of the measured value recording system
- Volume flow sensors in the main circuit (source + sink) Ultrasonic volume flow meters in the refrigeration circuit
- Training Stand S6: Hybrid collector as heat source for the heat pump and
power source
- Radiation sensor in front of the PV collector as pyrrheliometer
- Flow and return temperature sensor in the main circuit
- volume flow sensor in the main circuit
- Current and voltage sensor in the PV connection
- Training Stand S7: Wood pellet heating system
- Flow and return temperature sensor in the main circuit
- 2 additional temperature sensors in the mixer circuit
- volume flow sensor in the main circuit
- volume flow sensor in the mixer circuit outlet
4 precision measuring devices:
- 9 inputs for sensors per measuring device, i.e. up to 36 measured values can be recorded and processed simultaneously
- Intermediate storage of measured values via 8 MB flash memory; with data logger function;
- the precision measuring devices are interconnected
- The system can be subsequently expanded with additional precision devices if required
Sensors
- 26 x temperature
- 2 x pressure
- 4 x volume flow via pulse counting
- 3 x volume flow via ultrasonic measurement
- 1 x current clamp
Notebook
- Preconfigured notebook; with measuring program for recording, visualising and processing the measured values;
- Interface with graphical representation of the training stands
- Visualisation of the measured values
- Processing of the measured values via table formats
- Measured values and calculation results can be displayed in various diagram types, e.g. bar chart, line chart, pie chart, etc.
W-LAN function The measured values are transferred from the precision measuring devices to the notebook via a dedicated W-LAN function
