MJERENJE I MJERNI SISTEMI

The studient will be able to: 1. Interpret the importance of experiment ; 2.Describe the experimental instalation of a HVAC system (heating, ventilation and airconditioning) available at the Energy Lab of Mechanical Engineering Faculty; 3. Have and overview of the techniques for measuring temperature ; 4. Describe the principle of operation for thermo-electric sensing equipment (thermocuple, thermo resistors, IR camera, etc); 5. Understand and calculate the value of the time constant of a sensor / measurement system, in a Lab DAQ measurement setup; 6. Interpret and present the approach to experimentaly determine the characteristics of a orifice-type flow meter for measuring flow in a HVAC system. Conduct a experimental validation of the literature formulae to calculate the flow rate from measure differential pressure on the orifice meter differential pressure transducer. Carry out a calculation of flowrate for a given set of input data, as in real-life engineering scenario. 7. To interpret and calculate the energy flow for a HVAC system consisting of a heat pump and an airhandling unit, using the available laboratory equipment and devices; 8. Determine the properties of a fan-coil heat exchanger unit in the available HVAC system of the Lab; The water-air heat exchanger and the water-refrigerant heat exchangers. 9. Become profficient to measure basic electric quanties which determine the electric load of the machinery; 10. Calculate the coefficient of performance "COP" of a HVAC system
