Abstract

U ovom diplomskom radu napravljena je usporedba kompresijske i apsorpcijske dizalice topline zrak-voda na primjeru grijanja obiteljske kuće. Najprije je za obiteljsku kuću na području grada Zagreba, korisne površine cca. 220 m2 izračunato toplinsko opterećenje prema normi HRN EN 12831 te rashladno opterećenje prema VDI 2078. Također je napravljen proračun potrebne energije za zagrijavanje potrošne tople vode. Na temelju izračunatog opterećenja postavljeni su procesi kompresijske i apsorpcijske dizalice topline, a detaljnije je analiziran apsorpcijski ciklus. Zatim je proveden proračun potrebne godišnje energije za grijanje i hlađenje prema Algoritmu HRN EN ISO 13790. Dimenzionirane su komponente apsorpcijske dizalice topline zrak-voda, a dimenzioniranje obuhvaća termodinamički proračun isparivača i kondenzatora, proračun cjevovoda, akumulacijskih spremnika i cirkulacijskih pumpi. Na kraju je napravljena tehnoekonomska i energijska analiza dva spomenuta sustava.

Abstract (english)

This thesis covers a comparsion of compression and absorption air to water heat pump on the example of heating a family house. First, for a family house located in Zagreb, usable area approx. 220 m2, the calculation of thermal load according to HRN EN 12831 and the calculation of cooling load according to VDI 2078 is carried out. Also, the calculation of the energy required to heat domestic hot water is carried out. Based on the calculated heat load, the processes of compression and absorption pumps are set, and the absorption cycle is analyzed in more detail. Then, the annual required thermal energy for heating and cooling of the family house is calculated according to Algorith, HRN EN ISO 13790. The sizing of the components of the air to water absorption heat pumpi s made. It includes the thermodynamic calculation of evaporator and condenser, pipelines, storage tanks and cirkulation pumps sizing. Finally, a techno-economic and energy analysis of the two mentioned systems is made.
