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 and
evaporator 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 of
electrical 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.
