Abstract (Croatian)

U ovom radu je bilo potrebno napraviti termodinamički proračun kompresijske dizalice topline, koja treba osiguravati potreban toplinski tok za grijanje stambenog objekta. Proračun je napravljen za dva slučaja. U prvom je slučaju isparivač smješten u okolišnji vanjski zrak, a u drugom se slučaju isparivač nalazi u vodi konstantne temperature. I za jedan i za drugi slučaj određena je snaga kompresora, faktor grijanja, potrebna površina isparivača te je prikazan način odabira kondenzatora. U radu je dan i dijagramski prikaz temperatura radne tvari i toplinskih tokova u ovisnosti o lokalnoj površini isparivača. S obzirom da se kao sustav grijanja stambenog objekta koristi sustav podnog grijanja, na kraju je shematski prikazana dizalica topline s priključnom instalacijom za podno grijanje.

Abstract

In this paper it was necesary to make a thermodynamic calculation of compression heat pump, which should ensure the required heat flow heating the residential building. The calculation was made for two cases.In first case, the evaporator was located in the ambient outside air, and in second case the evaporator was placed in the constant temperature water. For both cases were determined power of compressor, heating factor, required surface area of the evaporator and the method for choosing the condenser type. The paper presents a diagrammatic view of the refrigerant temperature and heat flows as a function of the local surface area of evaporator. Since the heating system residential building uses is floor heating, in the end is schematically shown heat pump with terminal installation for floor heating.
