Abstract

Za diplomsko delo sem želel sestaviti univerzalno simulacijo okolja pametne hiše. Za bolj konkreten problem sem se odločil, da se bom osredotočil predvsem na nadzor temperature v različnih prostorih in prezračevanje teh prostorov. Dodal sem še osnovno senčenje, saj to prispeva pri pretoku energije iz zunanjosti v notranji prostor. Za simulacijsko okolje sem izbral program Matlab [2]. Program omogoča izvedbo matematičnih modelov in simulacij pretoka toplotne energije iz prostora v prostor. Najprej sem se osredotočil na sestavljanje matematičnega modela pretoka energij iz prostora v prostor ter vpliva zunanjosti. Ko sem imel sestavljeno osnovno simulacijsko shemo, sem se posvetil nadzoru temperature s PI regulatorjem. Enako sem ponovil še za pretok zraka v prostoru. Naslednji korak je bila sestava vmesnika med uporabnikom in simulacijo. Matlab [2] ima svoj program za sestavljanje vmesnikov, ki sem ga uporabil pri nalogi. Dodal sem tudi izračune porabljene energije posameznih grelcev. Končni produkt je simulacija temperaturnega nadzora posameznih sob, kjer lahko uporabnik nastavlja več temperatur na dan, postavlja vzorce, vklaplja in izklaplja krmiljenje in določa število ljudi za posamezno sobo za posamezni dan. Simulacija lahko teče največ en mesec na enkrat. Prav tako sem s pomočjo te simulacije poskusil določiti energetsko najbolj učinkovit način gretja, hlajenja in prezračevanja za ustrezne bivalne pogoje glede na porabljeno energijo.

Secondary title:	Simulation of the heating and air conditioning of residential premises
Secondary abstract:	For my thesis I wanted to create a universal simulation of a smart house environment. For a more specific issue, I decided to focus mainly on temperature control in different rooms and ventilation of these spaces. I also included basic shading, as it contributes to the flow of energy from the outside to the inside. For my simulation environment I chose the program Matlab [2]. The program allows for the execution of mathematical models and simulations of heat energy flow from one space to another. Initially, I focused on constructing a mathematical model of energy flow between spaces and the influence of the outside environment. Once I had the basic simulation diagram assembled, I turned my attention to temperature control using a PI controller. I repeated the same process for air flow within the space. The next step was creating an interface between the user and the simulation. Matlab [2] has its own program for building interfaces, which I utilized for this task. I also included calculations of energy consumption by individual heaters. The final product is a simulation of temperature control in individual rooms, where the user can set multiple temperatures per day, establish patterns, turn control on and off, and specify the number of people in a room for a given day. The simulation can run for a maximum of one month at a time. Additionally, with the help of this simulation, I attempted to determine the most energy-efficient way to heat, cool, and ventilate the living spaces according to the energy consumed.
