Eksperimentinis šilumos siurblio ciklo tyrimas, jo valdymo algoritmo parengimas ; Experimental Study of the Heat Pump Cycle, Elaboration of the Algorithm for Its Control
The master thesis analyzes an experimental heat pump used for heat recovery in a mechanical room ventilation system. The aim of the work is to examine the operation, control logic of the heat pump and evaluate the possibilities of its operation modes, cycle control by outdoor air temperature. A review of scientific literature and experimental tests of the heat pump were performed to achieve this goal. Tests were performed in 3 stages, after each stage, according to the results obtained the heat pump stand was improved and experimental modes were adjusted. During the experiment, the tendencies of the heat pump freon and air involved in the heat exchange parameters are analyzed with different combinations of expansion valve positions and compressor power. Knowing these experimental characteristics, the extent to which the combination of these two controls can be used to efficiently control of the heat pump according to the outside air temperature is assessed. Based on the results of the research the depending on the variable outdoor air temperature heat pump control algorithms are prepared. Conclusions and recommendations are presented. Thesis consist of 56 p. text without appendixes, 31 pictures, 8 tables, 16 bibliographical entries.
