“…In the hot and humid climate of Taiwan, a classic study of thermal comfort in an air-conditioned office building retrofitted with a total heat exchanger resulted in improvements in thermal comfort and air quality after the air-conditioning retrofit [242]. Other studies of thermal comfort in office buildings with air-conditioning were carried out in Thailand (neutral temperatures and thermal acceptability were determined) [243], in Malaysia (the main problem was overcooling and the neutral temperatures proved to be higher than those predicted by PMV) [244], in China (low relative humidity was the main cause of thermal discomfort) [245], in Hong Kong (neutral temperatures were determined and in the summer these were lower than those predicted by PMV) [246] and in Saudi Arabia (63% of users felt dissatisfied during the summer) [247].…”

“…However, the PMV-PPD model is based on controlled laboratory experiments, assuming that the human body passively accepts surrounding thermal conditions without adapting to temperature changes. Thus, it is usually most suitable to be used in air-conditioned spaces with mostly seated occupants, such as office buildings (Chen and Chang, 2012;Langevin, Wen and Gurian, 2013;Wang et al, 2014;Martínez et al, 2015;Gangisetti et al, 2016;Elizabeth Amudhini Stephen, 2018;Kwak and Huh, 2019;Tewari et al, 2019;Ali et al, 2020;Bagheri Moghaddam et al, 2021;de Oliveira, Rupp and Ghisi, 2021;Staveckis and Borodinecs, 2021). Previous research has established that the difficulty of applying PMV models is estimating occupants' clothing insulation and metabolic rate (Ma et al, 2021).…”

The building sector is one of the most resource-exhausting areas in global energy consumption. Maintaining good thermal comfort for occupants is the leading energy demand in buildings. The primary purpose of the current study is to identify the development of research areas on occupant comfort, pinpoint the gaps in knowledge and recommend directions for future studies. A scientometric analysis and a comprehensive systematic literature review are conducted using 792 sources. It is evident from the exponential increase in published papers that scholars are highly interested in this research topic. However, discrepancies remain between the two fundamental models of evaluating thermal comfort. There is a pressing need to balance thermal comfort while increasing energy efficiency. The foundation of achieving this balance can only be done by correctly evaluating the surrounding environment of occupants and understanding all the factors influencing human thermal comfort conditions. There is also a high potential in employing industry 4.0 technologies to assist in designing more innovative solutions for thermal comfort. Furthermore, there is a need for local thermal standards targeting specific regions. The lack of interoperability between BIM 3D modelling and energy simulation tools remains an obstacle.

“…However, in order to improve indoor air quality, a room needs to receive the necessary volume of outdoor air, which is limited by air conditioning load. Therefore, total heat exchangers are widely used in buildings as heat recovery equipment to reduce outdoor air load [2,3]. The ability to reasonably calculate the heat recovery volume is the key to the suitability analysis of the total heat recovery technology.…”

In view of the problem that the exchange effectiveness is calculated according to a fixed value or only considering the influence of outdoor air parameters when analyzing the suitability of total heat recovery for plate heat recovery equipment in air-conditioned spaces without humidity control, the indoor humidity calculation model and moisture balance equation were established in this research to predict relative indoor humidity. Moreover, the relationship between total heat recovery, effective heat recovery, and the reduction in outdoor air heating load was analyzed using a psychrometric chart of the outdoor air treatment process. Referring to the standard for weather data of building energy efficiency in the Ningbo region, 6 typical days were taken as the calculation conditions. The moisture balance differential equation was solved using MATLAB software to obtain numerical solutions for the hourly indoor air humidity ratio, relative humidity, exchange effectiveness, and effective heat recovery when adopting an air-to-air total heat exchanger in an air-conditioned room of an office, classroom, or commercial building in the winter. The results indicate that, under the calculation conditions, the relative indoor humidity of commercial buildings is relatively high, making it unsuitable for a total heat exchanger. The relative humidity of indoor air in offices and classrooms can be maintained above 30%, and the total exchange effectiveness of a total heat exchanger is between 45% and 100%. The effective total heat recovery was calculated as sensible heat recovery under most calculation conditions.
