TEHNOLOGIJA IZRADE UREĐAJA ZA HLAĐENJE I TOČENJE NAPITAKA

U uvodu ovog rada opisani su uređaji za hlađenje i točenje napitaka koji su u današnje vrijeme najučestaliji na tržištu. Opisuje se način na koji rade, te različiti modele uređaja na tržištu. Rad obuhvaća proračun rashladnog uređaja prema određenom zahtjevu kupca, te prikazuje specifične zahtjeve koje rashladni uređaj mora zadovoljiti. Proračun rashladnog uređaja zasniva se na temelju traženog kapaciteta istakanja, prilikom čega su odabrane odgovarajuće komponente za tražene uvjete hlađenja. Ovaj rad usmjeren je na proizvodni proces i kontrolu prilikom izrade rashladnog uređaja, stoga su u radu detaljno opisane proizvodnja, način i vrsta kontrole prilikom proizvodnje rashladnih uređaja. Opis proizvodnog postupka prikazan je kroz četiri glavna proizvodna procesa: proces obrade lima, savijanja cijevi, izrade rashladnih posuda i montaže uređaja. Faze izrade popraćene su slikama, opisom postupka, strojevima koji su korišteni prilikom izrade te opisom kontrolnih aktivnosti, od samog početka pa do pripreme za isporuku kupcu. Rad obuhvaća i eksperimentalni dio u kojem se provodi laboratorijsko ispitivanje rashladnog uređaja, kojim se dokazuje da rashladni uređaj zadovoljava traženi kapacitet istakanja. Laboratorijsko ispitivanje provedeno je prema normi ANSI/ASHRAE 32.2-1997 u poduzeću Oprema d.d.In the introduction of this paper there is a description of cooling and dispensing units which are nowadays most common in the market. It describes the way they work, and different device models on the market. This paper includes the calculation of the cooling units according to a specific customer requirement and shows the specific requirements that the cooling units must satisfy. Calculation of cooling units is based on the dispensing capacity, according to the calculation there are selected appropriate components for the required cooling conditions. This paper is focused on the manufacturing process and control during production of cooling unit, therefore, in the paper are described in details the production, the way and the type of control during the production of cooling units. The description of the production process is shown through four main processes: production process of sheet metal, tube bending, production of cooling container and mounting units. The stages of making are accompanied by pictures, description of the procedure, the machines used during the making and description of control activities, from the beginning until the preparing for delivery to the customer.The paper also includes an experimental part in which it is being implemented the laboratory testing of the cooling unit, which proves that the unit meets the dispensing capacity. The laboratory testing is carried out according to the norm ANSI/ASHRAE 32.2-1997 in Oprema d.d. company
