Principle
Pressures and temperatures in the circulation of the heat
electrical compression heat pump are measured as a function of time
when it is operated as a water-water heat pump. The energy taken up
and released is calculated from the heating and cooling of the two
water baths. When it is operated as an air-water heat pump, the
coefficient of performance at different vaporiser temperatures is
determined.
Benefits
- Different operating modes possible
- For both demonstration and student experiments
- Simple set-up
Tasks
- Water
heat pump: To measure pressure and
temperature in the circuit and in the water reservoirs on the
condenser side and the vaporiser side alternately. To calculate
energy taken up and released, also the volume concentration in the
circuit and the volumetric efficiency of the compressor.
- Air-water heat
pump: To measure vaporiser temperature and water bath
temperature on the condenser side under different operating
conditions on the vaporiser side,
- with stream of cold air,
- with stream of hot air,
- without blower.
If a power meter is available, the electric power consumed by
the compressor can be determined with it and the coefficient of
performance calculated.
