Abstract

V diplomski nalogi sem najprej predstavil splošno delovanje toplotne črpalke. Na kratko so opisane vse najpomembnejše komponente posamezne toplotne črpalke. Prav tako so na kratko opisane tudi vsi tipi kompresorskih toplotnih črpalk. Kasneje sem predstavil tudi izračun grelnega števila po standardu EN 255 in po uredbi EHPA (European Heat Pump Association V nadaljevanju sem na podlagi testiranja posameznih zunanjih toplotnih prenosnikov za toplotno črpalko predstavil ugotovitve in posamezne izračune grelnega števila . Pri tem se je upoštevalo zanesljivo delovanje toplotne črpalke pri vseh pogojih testiranja in dovolj visoko grelno število toplotne črpalke. Namen diplomskega dela je torej predstaviti različne tipe toplotnih prenosnikov in vpliv toplotnega prenosnika na delovanje toplotne črpalke. Tako so v tej diplomski nalogi predstavljeni štirje toplotni prenosniki, ki so se testirali pod standardnimi pogoji testiranja. Na koncu je na podlagi dobljenih rezultatov, predvsem dobro grelno število toplotne črpalke in zanesljivega delovanja, bil izbran najprimernejši in najučinkovitejši zunanji toplotni prenosnik za toplotno črpalko.

Secondary title:	Optimization of air-water heat pump with an external heat exchanger
Secondary abstract:	The diploma work starts with the presentation of the overall performance of a heat pump. All major components of the individual heat pumps and all types of compression heat pumps are briefly described and followed by the presentation of the COP calculation according to EN 255 and EHPA Regulation (European Heat Pump Association). Further on, findings and COP calculations tested on the basis of individual external heat exchangers for heat pump are presented. Reliable operation of heat pumps in all test conditions and sufficiently high heat pump COP were considered most important parameters. The purpose of the diploma work is therefore to present the different types of heat exchangers and the impact a heat exchanger has on a heat pump. Thus, the diploma work presents the four heat exchangers, which were tested under standard test conditions. Finally, the most appropriate and effective external heat exchanger for the heat pump was selected according to the obtained results, main criteria being high heat pump COP and reliable operation
