RAC-05 Introduction Heat pump is a machine which extracts heat from low grade heat sources and with addition of high grade energy in the form of electric motor or engine and delivers heat at a temperature.Suitable for either domestic, industrial or commercial purpose. EEE has designed Air and Water Heat Pump to demonstrate and analysis the cycle using refrigeration as a working fluid. The refrigeration cycle consists of Hermetically sealed compressor, water cooled condenser, filter/dryer, rotameter, thermostatic expansion valve, air evaporator and water evaporator with selector valves. Two additional rotameters are provided in water circuits of condenser andevaporator respectively to measure flow rates. Digital temperature indicator is provided to measure temperature at various position. THE LOW GRADE HEAT INPUT will be supplied by ambient air in the case of air evaporator or water in case of water evaporator, the HIGH GRADE ENERGY input will be supplied in the form ofelectrical energy to compressor. The amount of this input can be measured using energy meter. This tutor has been designed to achieve steady state within reasonable period so that students can complete their experiments within 2-3 hours. By varying operating conditions the performance of heat pump can be studied. SPECIFICATIONS 1) Compressor :- Hermetically sealed type Kirloskar make Ton capacity.2) Condenser :- Water cooled type shell and coil condenser with refrigerant inside the tube.3) Expansion valve :- Thermostatic Expansion valve.4) Filter/ Dryer of suitable capacity.5) Rotameter :- One for refrigerant circuit for R-12. One water Rotameter for condenser. Onewater rotameter for water evaporator.6) Evaporator :- a) Water cooled type shell &coil evaporator with Refrigerant inside the tube.b) Air evaporator- finned tube type with fan and motor.7) Multichannel Digital Temperature Indicator with Thermocouples to measure various temperatures.8) H. P. L. P cutout.9) Pressure gauge :- Two nos. For delivery and suction pressures.10) Energy meter :- To measure power consumption of compressor motor.11) Necessary valves, switches etc.1/3 RANGE OF EXPERIMENTS 1) Determination of co-efficient of performance of unit when working as heat pump.2) Energy balances for complete system over arrange of operating condition.3) To determine overall heat transfer co-efficient for condenser and evaporator.4) To observe effect of sub-cooling in the condenser on co-dfficient of performance of heat pump.
