The aim of this thesis was the modelling of heat flow processes in buildings and the designing of control systems for heat dynamics of buildings 'for' (to slowo mi sie tutaj nie podoba, lepiej bedzie uzyc USING) the chosen models.
Models available in the literature often describe physical phenomenons (napisalam ze tu brakuje slowa IN) too much detail, making them difficult to generalize and far too complex which prevents their use in researches and simulations.
In this paper, as the object of the regulation WAS AN adopted room which requires heating due to (PANUJĄCYCH) (panujacych - existing) weather conditions.
It is assumed that the control signal for mathematical models with electric heater is a power of 'a' (tutaj lepiej daj THE) heater, for central heating it is the temperature of the feedwater and for air conditioning it is THE temperature of supplied air.
The study 'concluded' (to jest calkowicie zle slowo, i przez to cale zdanie nie jest zrozumiale - tutaj trzeba ASSESSED) the mathematical models of the room created on the basis of heat balance taking into account such properties as the heat capacity of the walls and ceiling, the capacity of the heaters and the cooling water flowing through the central heating heater.
...On the basis of literature the chosen parameters to best reflect the simulation of the real object. ....
To nie jest zrozumialym zdaniem, co ty robisz z tym?)
In addition, the study 'concluded' (zle slowo, tutaj moze 'verified' albo cos podobnego, przez to slowo zdanie jest nie zrozumiale) the step responses for obtained models, designed temperature controls, tests for control systems and calculated indicators of the quality of regulation.
'Then' (w pismie, nie uzywamy sloa 'then' bo to nie jest fabula typu (Fifty shades of Grey..then he..then he...then...then), On the basis the Ziegler-Nichols tuning method (kto? co? cos tutaj brak) selected a value of PID actions 'then' (znowu to 'then...nie uzywaj tego w powaznych tekstach....wg mnie zrob to zdanie biernie....A value was selected on the basis of....which was (appropriately, slightly, greatly - musisz napisac cos) modified BASED on the 'basis' (nie, tu masz zle slowo, chyba masz na mysli 'results') of tests 'and' (nie, daj inne slowo) achieved the expected indicators of the quality of regulation.
Simulations were carried out in THE Matlab/Simulink environment. In Simulink 'modeled three control systems' (daj to bierneie...the three control systems were modelled) for each heating system separately in order to compare their 'work' (nie daj tutaj work, ale moze 'output capacity/efficiency - cos takiego).
Studies have shown that taking into account the heat capacity of the wall this significantly affects the time for obtaining the stable (stable -ok) control signal. Taking into account the heat capacity of the heaters and cooling water in the central heating 'heater' (heating heater - cos to nie wyglada dobrze, lepiej heating element/operations - cos takiego) THIS does not significantly affect the modeled object. It is possible that the accepted values przyjete - tez sie zastanowilam, ale moze usual, jak nie to zostaw 'accepted') for the heaters does not have reflected real object (zbyt dobrze - jak to znaczy, ze 'mniej jak dobrze', to 'less than slightly well). The analysis of the results showed a tremendous impact takING into account THE thermal storage, the values of which heat capacities are close to a thermal capacity of the air in the room. The control systems exhibit different 'behawior' (behaviour in BrE - behav...nawet nie wiem jak in AmE) the object depending on the heating system in the building, but the indicators of the quality of regulation are WELL within the accepted limits. The models do not fully reflect the behavior of the object and are only its approximation, but it should be 'remembered' (ja tutaj dalabym 'considered') that the obtained models set the parameters on the basis of macroscopic principles of conservation of THE energy (heat balance), as well as simplified models of phenomenons, eg. profits from solar thermal power.
