Summary: The study examines the impact of assuming whole-body uniform clothing coverage on the accuracy of standard thermal comfort models in hot and humid environments. It finds that ignoring the non-uniformity of clothing insulation distribution can lead to significant deviations in thermal sensation predictions. A new model that considers the non-uniformity of clothing coverage is proposed and evaluated against experimental data.

Summary: In this study, a human-PCM-clothing model was constructed to predict the cooling effect of phase change material (PCM) on thermal response in hot environments. The model analysis showed that PCM with high latent heat and appropriate melting temperatures benefits body cooling performance. This study can guide the choice of PCM packages and the human thermal response analysis in a hot environment.

Summary: Short term experiments have identified heat shock and cold response elements in many biological systems, but the impact of long-term low or high temperatures is not well documented. To address this, Antirrhinum majus plants were grown under control, cold, and hot conditions for two years. Results showed that flower size, petal anthocyanin content, and pollen viability were higher in cold conditions and decreased in middle and high temperatures. Leaf chlorophyll content was higher in cold conditions, while pedicel length increased under hot conditions. The control conditions were optimal for scent emission and seed production.

Summary: The purpose of this study was to investigate heat strain while wearing pesticide protective clothing (PPC) with different physical properties in hot environments. The results showed that under 80% relative humidity conditions, physiological variables and subjective perceptions were greater than under 50% relative humidity conditions. Compared to polyester/cotton work clothing, the commonly used nylon suit had a greater physiological burden, and there were no statistical differences between the Tyvek and nylon suit conditions, especially in the 80% relative humidity environment. During exercise, there were no differences in humidity sensation among the PPC conditions, but during recovery, subjects felt more humid in the Tyvek or nylon suit than in the polyester/cotton work clothing.

Summary: This study was conducted to investigate the influence of airflow within isolated hospital gowns on physiological-perceptual heat strain indices. The results indicated that the presence of airflow in these gowns significantly improved physiological-perceptual parameters in both men and women, enhancing safety, performance, and thermal comfort while reducing the risk of heat-related disorders.

Summary: This paper outlines the development of a finite element human thermoregulatory model using an anatomically and geometrically correct human body model. The model simulates thermal responses through a passive and active system, providing insight into human thermoregulatory responses to non-uniform and transient environments. Comprehensive validation shows predictions are accurate and acceptable, with comparisons of predicted temperatures at 29 sites with measured values in comfort, hot, and cold conditions.

Summary: Balancing heat production and loss is crucial for human beings to adapt to their work environment. Maintaining a proper core body temperature can be challenging in high heat-producing workplaces like hot underground mines. Therefore, compliance with related indices and standards is necessary to ensure worker safety.

Summary: In the study, the discrepancy between the PeSI and PSI under low heat strain conditions was evaluated, showing that PeSI may underestimate the heat strain compared to PSI. Participants with higher body fat percentage may have a decreased perception of heat strain, while fatigue, sleep status, and previous EHI may increase heat strain perception.

Summary: This study investigated the influence of ambient temperature steps on clothing heat storage and release. Results showed a positive correlation between temperature step magnitude and heat storage and release. The majority of heat storage was completed within 10 minutes after the temperature steps. Increasing the weight and specific heat capacity of the inner clothing layer improved heat storage in specific areas.

Summary: Heat stress is a serious problem faced by livestock, particularly for riding horses and racehorses that spend the majority of their time in stalls. This study evaluated the effectiveness of an ice horse blanket in reducing stall heat stress. The results showed that the blanket effectively decreased the horse's skin surface temperature, respiratory rate, and plasma cortisol level. The advantage of the blanket is its gentle cooling effect without the need for water or fans. This method can be applied not only to horses but also to other mammals kept in barns to reduce heat stress.

Summary: Mean radiant temperature is an essential physical quantity for evaluating thermal environments, with black globe thermometer being the most common measurement method. Studies have focused on factors like globe diameter, materials, and heat transfer modeling, but inconsistent results are due to difficulties in calibration. This study emphasizes on the accuracy of various types and sizes of globes through a metrological analysis in a controlled environment.

Summary: This paper quantifies the effects of using small globes to assess extreme hot thermal environments. Results show that small globes underestimate WBGT values by 1°C, but this can be corrected using specific correction coefficients. However, pocket WBGT meters based on small globes and psychrometric sensors underestimate WBGT by more than 10°C, especially at low air velocity and high radiative loads. Additionally, the underestimation of mean radiant temperature measured through small globes leads to an underestimation of allowable exposure times predicted by the PHS model.

Summary: The European Directive 844/2018, EN 16798-1 and -2, and ISO 17772 Standards emphasize the consideration of Indoor Environmental Quality (IEQ) when designing a new building or retrofitting an existing one. Thermal comfort, a crucial aspect of IEQ, is affected by the mean radiant temperature (tr), which cannot be directly controlled by HVAC systems. This paper compares different calculation methods of tr used by Energy Plus with the Design-Builder interface and analyzes their influence on thermal comfort evaluation in three buildings.
