20.500.12556/DKUM-21724 OGREVANJE IN HLAJENJE POSLOVNIH PROSTOROV S TOPLOTNO ČRPALKO ZRAK-ZRAK HEATING AND COOLING OF OFFICE AREA USING HEAT PUMP AIR-AIR V diplomski nalogi sem predstavil nov način ogrevanja in hlajenja poslovnih prostorov z uporabo toplotne črpalke zrak-zrak, oz. sistema s spremenljivo količino hladilnega sredstva. Po načrtu arhitekture sem predvidel postavitev sistema, določil toplotne dobitke in izgube objekta, ter ustrezno dimenzioniral sistem s pomočjo programskega orodja. Po primeru izračuna toplotnih izgub objekta sem s programskim orodjem izvedel tudi simulacijo porabe energije izbranega sistema. Pri tem sem ugotovil da so omenjeni sistemi zaradi svoje kompaktnosti zelo primerni za projekte rekonstrukcije objektov, prav tako pa se ponašajo z visokimi izkoristki in se lahko uporabljajo kot samostojni vir ogrevanja in hlajenja večjih moči. In my diploma I have presented a new way of heating and cooling of office area using an air-air heat pump or so called variable refrigerant flow system. According to architectural plans, I have foreseen a system layout, calculated cooling and heating load and dimensioned the system with help of manufacturers’ software. After an example of heating load calculation, I have implemented a simulation of energy use of the system. I learned that these systems are especially suitable for building renovations, mainly because of its modular and compact design and installation flexibility. Besides that, systems are very efficient and can be used as monovalent source of heating and cooling of bigger capacities.
