  12. Other Variables II

  13. Ambient and Room Temperature Sensors Jumo RTD Indoor / outdoor temperature sensor(PT100) - for temperatures from -30 to +80°C (200°C) - for use in HVAC - IP20 to IP65 protection - for 2-wire, 3-wire or 4-wire connections - fitted transmitter option 4 – 20mA or 0 – 10V

  14. LI-COR - Solar Radiation Sensor About 200 € Li-COR LI200SZ - silicon photovoltaic detector -Current output, which is directly proportional to solar radiation -Calibrated against an Eppley Precision Spectral Pyranometer (PSP) under natural daylight conditions in units of watts per square meter (W m-2) -Under most conditions of natural daylight, the error is < 5% (2). -Output - Typically 90 µA per 1000 W m-2

  15. Carlo Gavazzi - Energy Meter Type EM21 72D Main Outputs: Currents (A); Voltages (V); Apparent power (VA); Active power (W); Reactive power (var). Communication through a RS485 communication port Compressor, Circulators, Fan Coils, HP Controls (?)

  16. Brunata - Thermal Energy Meter Overview • Flow meter; • Two Liquid Temperature meters; • RS-485 Communication • Max. Flow16.5 m/h (HGP 15); • Max. Liquid Temperature 120 ºC (HGP 15). 3

  17. Thermal Energy Consumption Tin_ci (C) Tout_ci (C) Q (m3.s-1) Q (W) Q.t (Wh) Brunata HGQ Energy Meters

  18. Brunata – Flow Sensor Technology Michael Faraday’s physical law about induction Water is the conductor This principle allows for measuring range better than 1000:1

  19. Brunata – Components of a Heat Meter Flow sensor 2 temperature sensors Calculator with display

  20. Brunata – Calculation of Heat Energy E – Energy consumed in a period of time; V – Water volume passing through the meter in same period; – Average temperature difference between flow and return in the system; k – Correction factor for heat enthalpy and the volume mass at the temperature measured.

  23. Output file The data acquired by all these devices will be processed every minute into a string buffer and after 10 minutes the last 10 buffered strings will be updated into a FTP file trough the Internet. To create this string, the application will also read the cRIO-9074 board date and time to complete all the required parameters.
