Abstract
U ovome radu se izračunava potreba toplinske energije za grijanje i hlađenje referentne zgrade za obrazovanje gotovo nulte energije (nZEB) te pokrivanje navedenih toplinskih potreba jednim od dva tipa dizalice topline, tip zrak-voda s inverterskom tehnologijom ili tip zrak-zrak (VRF). U sklopu rada je predstavljen proračun za računanje toplinskog opterećenja u zimskom i ljetnom periodu prema normi HRN EN ISO 52016-1:2017. Navedenim proračunom je napravljena satna analiza toplinskih potreba referentne nZEB zgrade pomoću programskog paketa Matlab. Također je opisan proračun za računanje potrošnje električne energije i iznosa sezonskog faktora grijanja dizalice topline zrak-voda prema normi EN 15316-4-2:2017 put B. Za proračun satnih vrijednosti faktora hlađenja i potrošnje električne energije dizalice topline zrak-voda korištena je metoda interpolacije između proširenih vrijednosti faktora hlađenja od proizvođača. Po ugledu na EN 15316-4-2:2017 napravljen je proračun grijanja i hlađenja dizalicom topline zrak-zrak. Programskim paketom Matlab je napravljena satna analiza rada dizalica topline prema navedenom proračunu. Dobiveni rezultati satne analize uspoređeni su radi procjene kvalitete rada dva uređaja u razmatranim uvjetima.
Abstract (english)
This thesis deals with calculating energy needs for heating and cooling of a reference near zero energy building (nZEB) for educational purposes. The energy needs will be covered with one of two types of heat pump, air to water heat pump with inverter technology or air to air variable energy flow heat pump (VRF). As a part of the thesis, the calculation procedure for heating load according to the norm HRN EN ISO 52016-1:2017 will be presented. According to the calculation modelled on the norm the hourly analysis of the heat load is written in the program Matlab. Furthermore, the thesis describes the norm EN 15316-4-2:2017 way B. that deals in calculating electric energy needed for running an air to water heat pump as well as seasonal coefficients of power for heating. By adjusting the method described in the norm, a calculation regarding the heating and cooling modes for the air to air heat pump was done. The calculation of the cooling mode, regarding the air to water heat pump, was done by interpolating between the expanded number of measured values by the manufacturer. Using Matlab the hourly analysis of the heat pumps is made according to the stated calculation methods. The results of the hourly analysis of the heat pumps are compared to justify the usage of one of the two devices in the given conditions.
