The unit enables the students to study the Basic Principals of ice plant cycle within a short period. The Ice Plant Test Rig is designed for the study of thermodynamics of vapour Compression refrigeration cycle by way of demonstration and experimentation. It has a facility to measure various parameters for experimentation. Ice cans are kept in liquid tank, which is cooled by the refrigerant evaporator. As conventional ice plants take 12-24 hours to complete the cycle, this ice plant is specially designed to demonstrate process of ice formation to be complete within period of 4 hours and hence it is most suitable for laboratory use.

Learning Objectives/Experiments:
• To Study the Working of Ice Plant.
• To Study the Refrigerator Circuit.
• To Calculate Co-efficient of performance

Water to Water heat pump

DESCRIPTION :
Heat Pump and the refrigerating machine basically work on one and the same principle and with the same components. Heat pump is a machine, which delivers heat at a temperature suitable for domestic, Industrial and Commercial purposes. By added work input from the motor or engine it extracts heat from low-grade source. In many circumstances heat pumps can make valuable contribution to energy conservation. The majority of heat pumps operate on the vapour compression cycle using a refrigerant as the working fluid. Heat pump is fully sealed R-134A refrigerant system using water-to-water pumping principle. The equipment produces realistic results and has low thermal inertia so that unit stabilises very quickly and enables student’s maximum experimentation.
EXPERIMENTATION:
• Determination of co-efficient of performance of the unit when working as water-to-water heat pump.
• To Construction of Energy balances for completed system over a range of operating conditions.
