Parking ventilation - CO monitoring, selection and installation

  1. 1. Parking ventilation:CO monitoring, sensor selection and topography<br />
  2. 2. Parking area: Measuring parameter<br />Measuring parameters need to be measured and controlled, at parking area:<br />CO (carbon monoxide) for petrol vehicles<br />CO (carbon monoxide) and NO2 (nitrogen dioxide) for diesel vehicles<br />It is advisable to measure and monitor NO2 if parking area caters to diesel vehicles also.<br />
  3. 3. Calculation of No. of Sensors / Measuring points:<br />Number of CO sensor depends on many factors, such as:<br />Floor area of parking space: <br />Load at Exit & Entry to parking space: N = N+1 ,<br /> for exit and entrance (only one more if exit, entrance are same)<br />Parking space to be used by public or bulk transport vehicles: N = N +1, at unloading bay.<br />Where N = no. of CO sensor, L = length of parking space ( in mtr), W = width of parking space ( in mtr), A = area of parking space ( in sq mtr)<br />
  4. 4. Selection of sensor technology:<br />Sensing technology available:<br />Infra-red based<br />Electro-chemical based<br />Solid state semiconductor based<br />Infra-red based sensor (Not Available for all Gases) provide high accuracy but are expensive, while solid state Sensors are cheap but provide false readings, high gas cross-sensitivity, produce false alarm.<br />
  5. 5. Connection topography: Star Connection for analog system<br />
  6. 6. Connection topography: Bus Connection for digital system<br />Consultant or system designer can choose and design:<br /><ul><li>Branch topology
  7. 7. Tree topology</li></li></ul><li>Connection Topography design & selection:<br />Sensors (Measuring Points) + Controller / PLC / BMS/ SCADA system<br />Topography preference/recommendations<br />Star connection if sensors < 20<br />Bus connection if sensors > 20 <br />Bus connection will drastically compensate the cost of digital system, and ease of managing/controlling the sensors, hence overall cost of project will come down as compared to analog system.<br />
  8. 8. MSR Electronic Analog system:<br />MSR CO Sensor MA-0-1110<br />0-300 ppm meas. Range, Electro-chemical technology based sensor<br />Continuous monitoring<br />Poisoning stable<br />Modular plug-in technology – for PCB, sensor element, enclosure<br />Reverse polarity, Overload protected<br />IP44 protected enclosure<br />4 – 20 mAanalog signal output (Standard)<br />Response time t90 < 50 sec<br />
  9. 9. MSR Electronic Analog system:<br />MSR Analog controller MGC-04 series<br />Suitable for monitoring CO, CO2, NO, NO2, NH3, O2, SO2, H2S, CL2, ETO, combustible and refrigerant gases<br />Auto diagnostic watch dog with built-in error codes, fault LEDs<br />Five adjustable alarm thresholds for each channel<br />4 alarm relays with SPDT, potential-free, max. 250 VAC, 5A<br />analogoutputs, 4 - 20 mA<br />IP 65 protected enclosure<br />Can control up to 4 meas. Point in basic model, up to 24 measuring points with help of expansion modules<br />
  10. 10. MSR Electronic Digital system:<br />MSR Analog / Digital Sensor ADT-03-1110<br />0-300 ppm (50-2000 ppm optional) meas. Range , Electro-chemical technology based<br />Digital measurement value processing incl. temperature compensation<br />Serial interface RS-485 with modbus option<br />Continuous monitoring<br />Low zero point drift<br />Good stability to poisoning<br />Long life sensor, Modular plug-in technology, Easy maintenance<br />Reverse polarity protected, overload and short-circuit proof<br />(0) 4 - 20 mA / (0) 2 – 10V analog signal output, jumper selectable<br />IP65 protected<br />
  11. 11. MSR Electronic Digital system:<br />MSR Digital Controller DGC-05 series<br />up to 98 meas. Point in bus configuration<br />For monitoring CO, CO2, NO, NO2, NH3, O2, SO2, H2S, CL2, ETO combustible- and refrigerant gases<br />Auto diagnostic watch dog with built-in error codes, fault LEDs<br />Serial interface RS-485, with modbus option<br />Five free adjustable alarm thresholds for each transmitter<br />4 relays with SPDT, potential-free, max. 250 VAC, 5A<br />Fault relay with SPDT, potential free, max. 250 VAC, 5A<br />4 analog outputs, 4 to 20 mA<br />
