Evaluation of Effects of the Humidity Level-Based Auto-Controlled Centralized Exhaust Ventilation Systems on Thermal Comfort of Multi-Family Residential Buildings in South Korea

Abstract

Building air-tightness has been increased to make energy efficient buildings. However, various indoor air quality issues can be caused by high building air-tightness because it allows low air and moisture transmission through building envelop. In order to solve and prevent these issues, mechanical ventilation systems can be used to control the indoor humidity level. The purpose of this paper is to evaluate the performances of the Relative Humidity (RH)-sensor based auto-controlled centralized exhaust ventilation systems to manage indoor air quality and thermal comfort of multi-family residential buildings in South Korea. A series of field tests were performed for different target zones and for various moisture source scenarios. As a result, it was found that the auto-controlled centralized exhaust ventilation systems were able to control indoor air quality and to maintain the zones thermal comfort faster than the baseline cases that did not operate exhaust vents. The results presented in this paper can show the potential and the feasibility of the auto-controlled centralized exhaust ventilation systems for multi-family residential buildings in South Korea. It is expected that the results presented in this paper would be useful for building owners, engineers, and architects when designing building systems.

Effect of Lockdown amid COVID-19 Pandemic on Weather Parameters of Mid Hill Region of Jammu District of J&K, UT

“…it has been noticed that sales of vehicle since 2008 has been increased with at least 15% per annum and in relation to this, the transport demand is expected to rise by 200% between 2015-2030 [4,5]. So, the sure consequence of the rise of demand supply ratio is going to impact the weather quality in the entire country and Himalayas region in a negative aspect [6].…”

Thermal Comfort in Buildings: Scientometric Analysis and Systematic Review

“…The environmental parameters are indoor air temperature (Adunola, 2014;Zhang et al, 2017a;Cao and Deng, 2019;Jiang et al, 2021), radiant temperature (Saber et al, 2014b), relative humidity (Marincic, Ochoa and Del Río, 2012;Jing et al, 2013;Vellei et al, 2017;S. Yang et al, 2018b;Kong et al, 2019;Kwag et al, 2019;Deng and Chen, 2021;Zuo, Luo and Liu, 2021) and air velocity (Kalmár, 2018;Van Craenendonck et al, 2019;Sansaniwal et al, 2020). At the same time, the personall parameters are personal activity and clothing insulation levels (Chen, Moshfegh and Cehlin, 2013;Wang, Tian and Ding, 2013;Kwang Ho Lee and Schiavo, 2014;Song, Wang and Wei, 2016;Gautam et al, 2019;Wang, Kang and Zhou, 2019;Kim, Shin and Cho, 2021;Rupp, Kazanci and Toftum, 2021).…”

Review of IAQ in Premises Equipped with Façade–Ventilation Systems

“…In fact, with different locations for air inlets and outlets, the air may not be renewed, and this results in an increase in the amount of air to achieve a minimum IAQ. In order to combine the appropriate IAQ in the premises and energy savings, various methods are used to control centralized systems, for example, based on the relative humidity level [122] or the concentration of carbon dioxide in the internal air [123]. In many existing buildings, it may not be possible to install centralised ventilation systems [124][125][126][127][128].…”
