Abstract (Croatian)

U sklopu diplomskoga rada bilo je potrebno pratiti i analizirati rezultate dobivene mjerenjima na ispitnoj geotermalnoj dizalici topline u režimu hlađenja te napraviti proračun iste. Geotermalna dizalica topline se koristi za hlađenje dvije predavaonice unutar fakulteta površine 150 m2. Ogrjevna/rashladna tijela koja se koriste u režimu hlađenja ili grijanja su stropni ventilokonvektori. Navedena dizalica topline koristi propan kao radnu tvar. Toplinsko opterećenje predavaonica ljeti se proračunalo prema normi VDI 2078 koji su podijeljeni na unutrašnje i vanjske toplinske dobitke. Ukupni toplinski dobici za obje predavaonice ljeti iznose 11,76 kW. Temperaturni režim hlađenja odnosno vode u spremniku je 7/12°

Abstract

The aim of this master thesis was to measure the geothermal heat pump in cooling mode in order to monitor, analyze results, and produce the necessary budget calculations. Geothermal heat pump is used for cooling two lecture halls, 150 m2 in size, within the faculty. Heating/cooling units used in cooling or heating mode are the ceiling fan coil units. The before mentioned heat pump uses propane as its refrigerant. Classroom’s thermal load in summer was calculated according to VDI 2078, which was divided into internal and external heat gains. The total heat gains for both lecture halls in summer amount to 12 kW. Temperature mode or cooling water in the tank is 7/12°
