Abstract
The paper presents two mathematical models of the air drying with heat pump applied to an adiabatic dryer.
Elaboration of these models allows to optimize the system operation in order to decrease energy consumption of drying by adjusting refrigerant boiling temperature in the heat pump.
It was found that the difference between air dew point temperature and boiling temperature (TDP- TeV) correlates well the process data.
The conclusions drawn from the analysis of optimization results were checked out on the test rig. It was observed that the increase of system heat losses cause that the optimum value of the control parameter (TDP- TeV) moves towards its higher values the region of 18–20 K and the specific energy consumption (SEC) values increase. Due to constant swept volume of the heat pump compressor tested it is necessary, however, to adjust the mass flow rate of air dried. From the experimental data it follows that good insulation and leak proofing of the system are of great importance for obtaining low (SEC) values.
