Refrigeration Tutor Practicals: Transient condition VCRS COP and Psychometric processes

Title: 
To find the average COP of a Vapour Compression refrigeration unit working in transient conditions and compare it with the theoretical one and draw the varying cooling rate with time.

Objectives: 
•To calculate the average COP of the refrigeration unit working under transient conditions for cooling a fixed mass of water.
•To draw a graph of varying cooling rate vs time 
•To compare the actual performance parameters with the theoretical ones.



Title: 
Plotting of psychometric processes: Sensible heating & cooling, dehumidification & cooling and heating & humidification carried over in a Year-round air-conditioning duct of Refrigeration and Air-conditioning Tutor and also finding the heating and cooling efficiencies.

Objectives: 
•To conduct experimental trials of different air-conditioning processes in the year-round AC duct of RAC tutor
•To find the BPF of cooling and dehumidifying coil 
•To compare the actual performance parameters with the theoretical ones.
