The thermal comfort of elderly people in warm indoor environments is important because their higher risk heat stress. use local cooling devices may help alleviate In this study, 26 participants were recruited for climate chamber experiments neutral (26 °C, 40 % relative humidity (RH)), slightly (29 RH; 28 60 RH), and (33 32 50 RH) environments. Three tested: a table fan, evaporative device, air-cooled jacket. This study found, different environments, the by results an mean skin temperature decrease no more than 0.5 °C. sensation head torso has most significant impact on overall sensation. (MST) remains effective physiological indicator estimating after using devices. head, limbs, extremities plays substantial role predicting thermosensory (TMST) proposed based these parts can accurately predict MST. provides reference development future implications guiding selection nursing homes or residential elderly, it be utilized to formulate recommendations improving device design.

Efficient management of HVAC systems through coordinated operation of parallel chiller units: An economic predictive control approach

Energy and Buildings, Год журнала: 2024, Номер 304, С. 113879 - 113879

Опубликована: Янв. 3, 2024

In developed countries, air conditioning systems have become major contributors to energy consumption in buildings. Cooling installations made up of independent chiller units connected parallel pose a challenge finding the most energy-efficient management strategy. This article proposes novel economic model predictive control strategy optimize operation multiple-chiller HVAC according an cost comprising as well thermal comfort index. Provided that gradient function can be calculated or estimated, proposed controller only entails solution single quadratic programming (QP) problem at each sampling period, reducing computational requirements and thus facilitating deployment on commercial embedded platforms. The improves performance. As our numerical analysis shows, optimal sequencing is achieved for case dual-chiller plants. Moreover, adapts possible variations criteria, enabling system respond changes electricity price user preferences. A realistic study, using high fidelity building simulated TRNSYS, demonstrates effectiveness methodology. particular, more efficient than state-of-the-art QP-based controllers achieving reduction 5.19%, which line with targeted 7.9% by 2030 EU Green Deal's 'Fit 55' package.
