Šilumos atgavimo funkcijos galimybių šalčio mašinose įvertinimas ir pritaikomumas Lietuvos klimatinėmis sąlygomis ; Heat recovery option on chillers and its availability in Lithuanian climate
In this Master thesis a direct heat recovery option on the air cooled chiller and its availability in Lithuanian climate has been investigated. Also the review of chiller range, direct heat recovery technological issues and direct refrigerant vapor compression cycle has been explained in detail. Also the heat recovery option has been investigated in the specific administrative building with the chiller already installed. Chiller cooling chart has been calculated for the selected time period – a month of July. Chiller refrigerant circuits were modeled by using two independent computer applications. In accordance with the calcultated results, plate heat exchangers were designed. Possible amount of recovered heat was found and compared with building‘s heat demand for hot domectic water supply. The economical evaluation of heat recovery option was carried out. The results confirmed that the heat recovery option discussed in the thesis can increase energy consumption efficiency. Despite the fact that heat recovery in Lithuanina climate is only possible during the warm season, annual savings on energy consumption are sufficiently high to make the heat recovery measure an attractive option.
