“…At present, there are a lot of published papers relating to mathematical simulation of temperature conditions of buildings corresponding to residential, livestock, and industrial buildings. In the papers [8][9][10] mathematical models of temperature adjusting systems inside residential buildings are considered. Insolation of buildings is considered in the papers [10,11].…”

Research stages of the indoor temperature adjustment system have been suggested. The capability assessment of indoor temperature adjustment with analog and discrete models of the control system was carried out. Robust absolute stability of the control system to the influence of endogenous and exogenous uncertainties was studied. Analytical results of the investigation were confirmed by a simulation conducted with the help of Matlab

“…Modeling multi-zoned buildings is not a new concept. Traditionally, building simulation tools are implemented for multi-zoned thermal models 4 . Since, room-partitioning layout for a floor plan is not entirely defined during the schematic design phase, modeling analyses are more focused on geometrical aspects.…”

A framework for creating thermal zones in a building for effective and efficient heating ventilation and air conditioning (HVAC) system design is introduced here. This method is based on simple “sort and eliminate” schemes and requires design cooling loads of conditioned spaces obtained from load calculation tools as primary input. The developed methodology is applied for creating thermal zones, determining corresponding supply conditions and ascertaining sizing of a dedicated outdoor air system (DOAS) with local recirculating units. A simulation study on a prototype-building model shows that a DOAS coupled with zoned recirculating systems that serve distinct thermal zones in a building (zoned model) perform comparatively better in controlling both space temperatures and humidity without significantly compromising HVAC energy and chiller loads than un-zoned HVAC systems serving the whole building as a single thermal block (un-zoned model). The consistency in the performance of zoned HVAC systems is verified by applying three different simulation weather files for New Delhi. Better performance along with logical and computational simplicity makes this design procedure a good alternative to traditional methodologies.

“…Similarly, a cost-effective building thermal model was verified by EnergyPlus [19]. What is more, EnergyPlus and MATLAB were integrated by BCVTB [20] to develop a cooling load prediction model for optimizing HVAC control, and the model parameters were recognized using the data calculated by simulation tool [21,22]. The above researches show that the lumped parameter model has a strong ability to forecast the indoor temperature and the cooling load, which is suitable for the MPC.…”

“…The mean radiant temperature which is used for a standing person [31] can be calculated with (21). Since there is a window on the south surface of envelope, the south surface temperature is calculated by the area-weight average temperature of window surface and wall surface (22). The simplified thermal model for radiant system is tested by TRNSYS and the testing results with various floor temperatures, air volumes, and supply air temperatures are shown in Figures 10-12.…”

MPC has the ability to optimize the system operation parameters for energy conservation. Recently, it has been used in HVAC systems for saving energy, but there are very few applications in radiant cooling systems. To implement MPC in buildings with radiant terminals, the predictions of cooling load and thermal environment are indispensable. In this paper, a simplified thermal model is proposed for predicting cooling load and thermal environment in buildings with radiant floor. In this thermal model, the black-box model is introduced to derive the incident solar radiation, while the genetic algorithm is utilized to identify the parameters of the thermal model. In order to further validate this simplified thermal model, simulated results from TRNSYS are compared with those from this model and the deviation is evaluated based on coefficient of variation of root mean square (CV). The results show that the simplified model can predict the operative temperature with a CV lower than 1% and predict cooling loads with a CV lower than 10%. For the purpose of supervisory control in HVAC systems, this simplified RC thermal model has an acceptable accuracy and can be used for further MPC in buildings with radiation terminals.
