A review of research on dynamic thermal comfort

Abstract

Nowadays, people’s requirements for comfort are getting higher and higher, and traditional steady-state thermal comfort environment sometimes cannot meet people’s requirements. Dynamic thermal comfort is considered to meet people's requirements for comfort better than traditional thermal comfort, and it is also conducive to the health of occupants and building energy conservation. Therefore, this article reviews the literature on dynamic thermal comfort. First, this article briefly describes the transition from a steady-state thermal environment to a dynamic thermal environment. Next, this article reviews the research related to dynamic thermal comfort, such as the frequency of airflow fluctuations, simulation of natural wind, thermal prediction models, the use of intelligent detection equipment, and personal environmental control. This article summarizes the related research and development of dynamic thermal comfort from the aspects of dynamic airflow parameters, indoor thermal environment regulation, thermal experience, etc. This article aims to illustrate the necessity of the development of dynamic thermal comfort and its current results. The results show that under the trend of the artificial intelligence era, dynamic thermal comfort still has broad development potential. This article It can provide some research ideas for subsequent thermal comfort research. Practical application: This paper summarizes the research and development of dynamic thermal comfort from dynamic airflow, indoor thermal environment control, thermal experience, etc., and makes appropriate extensions and prospects accordingly. At the same time, the necessity of combining thermal comfort with AI trends is emphasized. This paper can provide references and ideas for thermal research on thermal comfort.

Thermal and draught perception in fluctuating stratified thermal environments with intermittent impinging jet ventilation

“…The 2-minute and 5-minute pulses with intermitted stratum ventilation systems were investigated by Tian and colleagues [26]. Thus, lower pulsating periods may have different effects on occupant thermal comfort, and lower pulsating periods may have more effects on turbulent intensity rather than thermal reduction and recovery during the Pr and Pf durations [44,47]. This uncertainty should be resolved in future works.…”

Assessing the Effect of Building Skin Adaptability on Energy Consumption in Hot Arid Regions

“…This could be achieved in several different ways, for example by introducing controlled airflow in the wall cavity or using moveable insulation panels that can be repositioned to a configuration that is suitable for current external conditions. There are several different concepts that use the response to water as a mechanism for change as stated by Cao et al (2021). Material like the well-known fabric Gore-Tex does not change per se but behaves differently depending on the state of the water.…”

“…We conducted a research project in this region to develop sustainable and energy efficient architecture. The most crucial design challenges in hot, arid regions involve thermoregulation and light harvesting (Cao et al, 2021;Naglaa, 2016;Laracuente, 2015). We applied a kinetic shading system to the building skin and proposed a novel system to optimise heat gain, daylight harvesting and energy efficiency.…”

Development of a Coupled EnergyPlus-MATLAB Simulation Based on LSTM for Predictive Control of HVAC System

“…Alfano et al [24] summarized the calculation methods of thermal comfort software on the APP market and the problems needing attention in the process of PMV calculation. Cao et al [25] reviewed the research related to dynamic thermal comfort, aiming to explain the development, prospects, and necessity of dynamic thermal comfort research. Somu et al [26] used transfer learning and a comprehensive thermal comfort evaluation index to solve the lack of thermal comfort samples.…”
