Open-air ducts convey conditioned air along the surface of an open duct due to Coanda effect. In nozzle-blown conditioning, when heat load is large, jet flow falls temperature difference, and flying distance reduced. Therefore, we attempted improve by installing open-air studied their application office space as a case study using CFD analysis. verification experiment, it was confirmed that installation improves thermal environment increasing efficiency distribution.
Abstract Electrochromic (EC) glazing reduces the cooling load via solar radiation shielding. However, excessive shielding increases heating load. In other words, energy‐saving effect of EC is dependent on energy performance building. This study compares and loads reduction effects static under various conditions to evaluate regional applicability in Japan. Furthermore, maximize effect, we employ a machine learning (ML)‐based operation its efficiency. A parametric conducted based standard...
Natural ventilation is an essential component in sustainable building designs. However, it remains difficult to incorporate the system successfully because utilizable amounts of ambient energy resources differ according project conditions such as climates. Moreover, lack a quantitative metric that could encourage architect design proper plan and façade for natural at schematic stage being recognized barrier successful achievement ventilation. An inappropriate architectural would make...
Abstract Machine learning (ML) is a useful technique for improving building operations. However, if data can only be obtained from target building, the shortage will limit use of general ML models. To overcome this issue, simplified targets and limited numbers feature variables are required. In engineering, physics used to promote implementations. paper, case study targeting operation engineered natural ventilation performed based on energy simulations. The issue select preferable opening...
An airflow window is a system to improve solar blocking performance of windows. It practically beneficial system, however, still has potential the by controlling air flow in cavity between glazing. In this development, we apply Dynamic Insulation technique into window. CFD analyses were carried out measure thermal performance. The results show that declines heat gain coefficient as well surface temperature inner glass observed. effects radiant environment at perimeter zone office buildings.
In office buildings, reducing the heat load and improving thermal comfort in perimeter area are important issues. Airflow window (AFW) have been widely practiced buildings. The impact of ventilation path design cavity layer AFW is discussed this paper. addition, a high-performance which applied dynamic insulation (DI) technique developed. CFD analysis was carried out to evaluate performance system. It confirmed that system we developed improves solar blocking performance.
Abstract Airflow windows (AFWs) help to stabilize the thermal environment in perimeter zone and also allows for switching between solar‐shielding solar heat acquisition operations. This is based on method of channelizing air discharged from its cavity layer, either by using a total enthalpy exchanger choosing exchange or otherwise. It has certain thickness owing blinds that are installed layer. The purpose this research develop window system uses electrochromic (EC) glass, instead blinds, as...
Air-conditioning control should be controlled by targeting the sensible temperature of living area. However, it has not been realized because there is no easy way to grasp temperature. Therefore, as a new sensing method for grasping temperature, we focused on function measuring surface with an infrared sensor. We mainly verified relationship between sensor and each CFD analysis that reproduced thermal environment office. As result, was shown can estimated using
It is necessary to improve solar blocking performance and reduce heat gain coefficient (SHGC) of openings in office buildings order the cooling loads. Airflow windows are often practiced Japan’s buildings. In this research, we apply a Dynamic Insulation (DI) technique into an airflow window system performance. Computational fluid dynamics (CFD) analyses have been used measure thermal numerical opening model. case using conventional model, inner-surface temperature inner glass 29.4℃. DI...
