Specifications:

• 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.
