“…The variables are said to be reliable if the value of Alpha Cronbach > 0.6 and it is valid because the output that is shown from software SPSS 16.0 is above r table, 0,188. After using HOQ, to identify the prioritizing of customer criteria, AHP (Analytical Hierarchy Process) method was used in this research [18]- [20]. AHP was used to identify the prioritizing of houses' criteria in prone areas.…”

The aims of this research are to determine earthquake-safe housing development criterion in Padang City and find the relationships level of these criterions with customer requirements. The data of consumer perceptions on which is safe houses in prone areas to earthquake and tsunami was collected by questionnaires. The questionnaires used in this research were divided into two phases. In the first phase, the questionnaires were distributed to 30 consumers for the purpose of validation. In the second phase, the questionnaires were disseminated to 109 residents (consumers who buy housing on "Tsunami Yellow Zone" and developers who develop housing on the same area) and the results were processed using QFD (Quality Function Deployment) and AHP (Analytical Hierarchy Process). AHP showed the priority level of each indicator within the criteria. The results of this research, It can be seen that criteria for earthquake-safe housing development in the city of Padang can be sorted as follows: Implement technical factors in building earthquake-safe homes, Taking into account the legal and environmental aspects, Providing service facilities around the housing, Housing facilities and infrastructure, Marketing factor friendly, Low Cost and Pay attention to the aesthetics surrounding factors of housing. This research focused on housing developers and consumers in a disaster-prone area such as Padang City. The value of this research is to know the consumer requirements and its relationships with developer's technical characteristics. In the end, these developers will consider the criteria that required by the consumer and make the developed safer housing for consumers at the disaster-prone area.

Thermal Energy Storage (TES) and Demand Response (DR) offer unique benefits to reducing the electricity consumption, carbon emission, investment, and operational cost of generating cooling energy by bridging the gap between cooling energy demand and production. To provide comprehensive guidance to policymakers, system planners, investors, clean energy advocates, and other relevant parties to accelerate the development of TES and DR technologies, this paper provides a comprehensive overview of the most common TES and DR strategies for cooling purposes, covering the working principles, advantages, development stages, technical limitations, suitable applications, and potential growth opportunities in the transition towards low carbon economy. The research directions and policy recommendations are also discussed for better TES and DR development and deployment, especially in Asia. Energy users and system planners can choose the most suitable TES and DR technology to reduce electricity consumption and carbon emissions for their energy systems, while policymakers, investors, and clean energy advocates can contribute to removing the economic, regulatory, or customer-related barriers to TES and DR deployment, which will jointly help fully release the enormous economic and environmental potential of TES and DR technologies.

Thermal performance of an accumulator unit using phase change material with a fixed volume of fins

Summary Melting rate enhancement inside an accumulator unit for a phase change material (PCM) has been numerically investigated in a shell‐and‐tube (S‐T) arrangement that incorporates the circular type of fins, considering a fixed total volume of fins. The number of fins was chosen as the design parameter. The heat transfer fluid (HTF) was chosen as water that flows through the selected accumulator unit during the process of melting. The computational fluid dynamics (CFD) technique has been utilized for the simulation of the accumulator using ANSYS FLUENT software by considering a two‐dimensional axisymmetric cylindrical accumulator in a vertical direction. During the melting process, two heat transfer mechanisms were considered, namely, conduction and convection. The HTF flow was 5 L/min with a flow temperature of 358 K for charging. The predicted complete melting time of the PCM decreased by 53.125%, 65.625%, 71.875%, and 71.875% for fins numbering 6, 18, 30, and 36, respectively, compared with the S‐T without fins where it took approximately 480 minutes to melt completely. The optimal fin parameters are recommended in this study as follows: number of fins N = 30, thickness t/d = 0.01858, interval d/L = 0.03227, and aspect ratio t/h = 0.015. These recommended values maximize the thermal performance of the selected accumulator unit. The effects of changing the flow rate of the heat transfer fluid and its inlet temperature have been found to be significant on the PCM melting rate. The total melting time of the PCM is found to be reduced by about 57% when the inlet flow temperature is increased from 343 to 358 K. Moreover, the total melting time reduces by about 70.5% with an increase in the heat transfer fluid mass flow rate from 0.15 to 5 L/min. Furthermore, increasing the HTF flow rate from 0.15 to 5 L/min leads to a reduction of about 61.1% in the predicted total time that is required for solidification. The temperature differences for low flow rates are greater than those for high flow rates. The novelty of this study is in investigating the performance at a fixed total volume of fins.
