CARA PENGAMBILAN DATA PRAKTIKUM LABORATORIUM MESIN PENDINGIN

Summary

In this instructional video, the presenter explains the procedure for data collection during a refrigeration machine experiment. The process begins with starting the machine, adjusting settings, and activating components like the compressor, boiler, and fans. The key data gathered includes temperature and pressure readings of the refrigerant at various stages, as well as flow rates of the water entering and exiting the boiler. The presenter emphasizes the importance of taking measurements at regular intervals and ensuring the system is properly shut down once data collection is complete. The video provides clear, step-by-step guidance for handling the refrigeration machine.

Takeaways

• 😀 First, power on the cooling machine by raising the switch and adjusting the settings according to the experiment variations.
• 😀 The fan is activated using the control switch, which is crucial for proper operation.
• 😀 Next, turn on the compressor and boiler according to the set variations for the experiment.
• 😀 Once all equipment is turned on, wait for the condensate water to drip three times before proceeding with data collection.
• 😀 Data collected includes temperature measurements for various points, such as the web, B, and other specified sections of the machine.
• 😀 Pressures are measured at multiple stages: refrigerant entering and exiting the condenser and evaporator.
• 😀 Flow rate data is collected for both the water entering the boiler and the condensate water exiting.
• 😀 Power consumption of the boiler and other equipment is also measured during the experiment.
• 😀 Data is collected every 10 minutes after the condensate water drips three times, ensuring a consistent interval for analysis.
• 😀 After data collection, wait for 10 minutes, then repeat the process of collecting the data again, if necessary.
• 😀 Once all data is collected, power off the equipment, starting with the compressor, followed by the fan, and lastly, the boiler.

Q & A

What is the first step in the process described in the script?

The first step is to turn on the refrigeration machine by raising the switch and adjusting the settings according to the variation available.

What does the fan control switch do in the process?

The fan control switch is used to turn on the fan of the refrigeration machine.

What equipment is turned on after the fan?

After turning on the fan, the compressor is turned on, followed by the boiler, according to the specified variation.

What happens after turning on the equipment?

Once all the equipment is turned on, the process waits for the condensate water to collect and drip three times, which takes a bit of time.

What kind of data is collected during the practicum?

The data collected includes temperature readings (such as the temperature of the refrigerant entering and exiting various components), pressures (like those inside the condenser and evaporator), and flow rates (like the water entering and exiting the boiler).

How often are the data points recorded?

The data is recorded every 10 minutes after the condensate water has dripped three times.

What additional data is collected regarding power consumption?

In addition to temperature and pressure data, the power consumption of the boiler and the refrigeration machine is also measured.

What is the purpose of waiting for the condensate water to drip three times?

Waiting for the condensate water to drip three times ensures that the system is stable and ready for accurate data collection.

What is done after all data has been collected?

After collecting all the necessary data, the equipment is turned off in reverse order: first the compressor, then the fan, and finally the variation settings.

What should be done after turning off the equipment?

After turning off the equipment, the process concludes, and the practitioner should ensure everything is safely powered down and shut off.
