Product Description

The basic conceptualization of a heat pump can be understood as a machine or device that delivers heat from one area which is at a lower temperature to another are which is at a higher temperature by using mechanical work or a high-temperature heat source. Thus a heat pump may be transformed as a "heater" if the motive is to warm the heat sink, or as a "refrigerator" if the motive is to cool the heat source. Hence heat pumps make a valuable contribution to energy conservation by utilizing the self generated energy to the fullest because in either case, the operating principles are identical. Heat is moved from a cold place to a warm place or vice-versa. Heat pumps operate on the vapour compression cycle using a refrigerant as the working fluid as a medium to transfer heat. Heat pump is fully sealed R-134A refrigerant system using water-to-water pumping principle. The trainer setup is designed to provide real-time operational behavior and is specially drafted to a low thermal inertia so that equipment stabilizes quickly and which gives the students a window for maximum experimentation.


The latest lab set-up is designed with an inbuilt feature to interface the heat pump system with computer which enables to log the experimental data using computer. The real time data acquisition is be done by interfacing the set-up with computer using specially designed software. This software allows the user to have complete access to data logging and printing the stored data. An additional feature incorporated in the software allows the spread sheets to be prepared in Excel also for convenience of handling the data.
