VIZUALIZACIJA IN REGULIRANJE TOPLOVODNEGA OGREVALNEGA SISTEMA

LUISA, SEVERIN (author), Žemva, Andrej (mentor)

POVZETEK V diplomskem delu bom uporabil nekaj splošnega in praktičnega znanja iz našega družinskega podjetja, kjer sem zaposlen. Moje delo obsega montažo, servis in popravila ogrevalne tehnike toplovodnega sistema ter nastavljanje raznih parametrov na regulacijah ogrevalnih naprav. V prvem delu diplomskega dela bom opisal elemente ogrevalne tehnike, ki se jih uporablja v toplovodnem sistemu stanovanjske hiše. Zanima me, kakšno je breme investicije in energenta, ki ga izkoriščamo za potrebe ogrevanja. Opisal bom smernice za prihodnost, pri čemer se bom osredotočil na nižanje stroškov ogrevanja ter na ohranitev lagodja bivanja. Krmilje, skupek senzorjev in motorjev, ki je danes na voljo, je z vidika varnosti, izkoristka energentov in kakovosti bivanja dobro razvito. Pri svojem delu pa se dnevno srečujem z vmesniki človek-stroj (HMI), ki so s stališča uporabnika zapleteni za uporabo. V drugem delu diplomskega dela bom s (PLK) krmilnikom Samba SM35-J-R20 podjetja Unitronics z vgrajenim grafičnim zaslonom na dotik (eng.: touchscreen), poskušal približati sistem ogrevanja tudi najmanj veščim uporabnikom. PLK + HMI proizvod je tudi cenovno konkurenčen trenutnim krmilnikom za manjše objekte. V delu bom napisal program in izrisal HMI vmesnik za en ogrevalni krog. Krmilil bom tripotni motorni mešalni ventil za vzdrževanje želene temperature predtoka in obtočno črpalko za kroženje vode v toplovodnem sistemu. Podatki, ki jih bom pridobival, bodo: zunanja temperatura, sobna temperatura, temperatura toplotnega vira in temperatura predtoka. Ti bodo preko tipal Pt1000 in temperaturnega pretvornika P7R-10-2 posredovani PLK krmilniku preko serijske komunikacije RS485.

• Title: Visualization and control of hot water heating system

Abstract

ABSTRACT This thesis will be based on general and practical knowledge from our family business, where I work. My tasks involve assembly, service and repairs, heating technology in the hot water heating system and making adjustments to different parameters for the regulation of heating devices. In the first part of the thesis I will describe the elements of the heating technology, that are used in the hot water system of a residential house. I will try to determine the burden of investment and energy product, that is used for heating. I will also describe the guidelines for the future, and devote special attention to reducing heating costs and maintaining the quality of life. The hardware and the software are already highly developed in terms of safety, energy product utilisation rate and quality of life. However, users find the human-machine interface (HMI) complicated to use. The second part of the thesis will involve the Samba SM35-J-R20 (PLC) controller with a built-in graphic touch screen produced by the company Unitronics. I will try to bring the heating system closer to less skilled users. The PLC + HMI product is competitive to current controllers for smaller buildings in terms of price. In the thesis I will design a programme and an HMI interface for one heating cycle to control the three-way motor mixing valve ensuring the desired temperature of the preflow and the circulation pump for the circulation of water in the hot water system. The following data will be collected: outside temperature, room temperature, temperature of the heat source, preflow temperature. The data will be sent to the PLC controller using Pt1000 sensors and the P7R-10-2 temperature converter via the RS485 serial communication.
