Specially created for laboratory research and teaching, this trainer demonstrates the vapour absorption cycle with aqua-ammonia refrigerant. It covers test ranges from -5C to 55C, pressure readings up to 5 bar, and specimen capacity using standard sample bottles, making it highly versatile for various educational experiments.

Enhanced Safety and Robust Build

Safety is prioritized with features like overload protection, leakage sensors, and emergency stop. Constructed from rugged powder-coated CRCA steel and copper components, the trainer maintains low noise levels and is suitable for continuous educational use. Its floor-mounted design ensures stability during operation.

FAQs of Computerized Vapour Absorption Refrigeration Trainer:

Q: How does the Computerized Vapour Absorption Refrigeration Trainer operate without a compressor?

A: This trainer relies on the ammonia-water vapour absorption cycle, eliminating the need for a mechanical compressor. Ammonia is absorbed in water, heated, and separated by thermal energy, resulting in cooling through cyclic absorption and regeneration.

Q: What is the recommended process for setting up the trainer in a laboratory environment?

A: Install the trainer on a floor-mounted surface, connect the required 230V AC power supply, and ensure cooling water is supplied at 3-5 LPM to the absorption unit. Use the provided USB or serial interface to link the system with a Windows PC for data logging and monitoring.

Q: When should the safety features such as emergency stop or overload protection be used?

A: Activate the emergency stop or rely on overload and leakage detection if abnormal operation, excessive noise, or any system fault is observed. These features protect users and equipment during unforeseen incidents or malfunctions.

Q: Where can the data logging software be accessed and what are its compatibility requirements?

A: The data logging software is included with the trainer and runs on Windows-based computers. Simply install the software using the user guide, and connect the trainer via USB or serial port for real-time data acquisition and analysis.

Q: What advantages does computerized control bring to educational and research applications?

A: Computerized and PLC-based control enables precise measurement, automation, remote monitoring, and detailed data acquisition. This enhances learning outcomes, performance analysis, and allows for systematic experiments that replicate real-world industrial scenarios.

Q: How can students use the trainer to study performance characteristics?

A: Students can perform repetitive experiments, adjust test speed up to 150 rpm, and observe real-time temperature and pressure changes across a range of -10C to 70C and 0-5 bar. All results can be logged and reviewed via digital display and computer interface for comprehensive analysis.
