Refrigeration & Heat Pump | COP, Reversed Carnot, P-V Diagram, Condenser Effect [GATE, ESE, PSUs]

In this video, we solve multiple-choice questions from GATE and ESE on Refrigeration Cycles and Heat Pumps. Topics covered include VCR cycle modifications, reversed Carnot cycle, heat pump with R22, air refrigeration P-V diagram, and the effect of condenser temperature. Problems Solved: 1. VCR Cycle – Throttling replaced by isentropic expansion (COP comparison) 2. Reversed Carnot Refrigerator – Power required for given heat gain 3. Heat Pump with R22 – Enthalpy at isentropic compressor discharge 4. Air Refrigeration Cycle – Correct P-V diagram 5. Refrigeration Plant – Effect of condenser temperature on compressor power Concepts Covered: Vapour Compression Refrigeration (VCR) Cycle Isentropic Expansion vs Throttling Reversed Carnot Cycle COP of Refrigerator and Heat Pump Carnot COP = T_L / (T_H – T_L) Heat Pump with R22 – Enthalpy calculation Air Refrigeration Cycle – P-V Diagram Effect of Condenser Temperature on Power Input Ideal for GATE, ESE, and university Refrigeration & Air Conditioning courses.#Refrigeration #VCRCycle #ReversedCarnotCycle #HeatPump #R22 #AirRefrigeration #COP #IsentropicExpansion #Throttling #CondenserTemperature #PVDiagram #RefrigerationAndAirConditioning #Thermodynamics #GATE #ESE #MechanicalEngineering #HVAC #SolvedProblems
