ENERGY EFFICIENCY ANALYSIS OF HEAT PUMP WATER/WATER AND AIR/WATER FOR HEATING AND COOLING OF GENERAL PURPOSE BUILDING

V diplomski nalogi je predstavljena izbira in dimenzioniranje toplotne črpalke voda/voda in zrak/voda za večnamenski objekt. Kot podlaga pri izbiri toplotne črpalke za ogrevanje je izdelan transmisijski izračun večnamenskega objekta in za potrebe hlajenja so izračunani dobitki toplote v večnamenskem objektu. Po določitvi vseh parametrov sta bili izbrani, ter tehnično in ekonomsko primerjani toplotni črpalki voda/voda in zrak/voda. Toplotna črpalka voda/voda je montirana v samem večnamenskem objektu in tako se je na podlagi dejanskih obratovalnih ur za ta večnamenski objekt naredila primerjava med obratovalnimi stroški ene in druge toplotne črpalke. V nalogi je bilo na koncu ugotovljeno, da je montirana izvedba toplotne črpalke voda/voda ekonomsko bolj upravičene tako s stališča stroškov nabave, kot s stališča stroškov obratovanja.This diploma work presents selection and design of heat pump water/water system and air/water system in multi-purpose building. As a basis for selection of the heat pump for this building, heating system the transmission is calculated and for the cooling the heat winnings. After the definition of all the necessary parameters the selected heat pumps of system water/water and air/water are technically and economically compared. Heat pump water/water is already mounted in the multi-purpose building and therefore the comparison between the actual operating costs with air/water heat pump was shown. Finally this diploma work shows that the mounted water/water heat pump is economically more justified in both terms operating expenses and the starting prize of the heat pump
