In this study, the thermal efficiency of a polymer collector with unglazed photovoltaic thermal (PVT) system was determined. Overall heat loss was estimated using the heat energy balance method. Based on the analysis, the heat removal factor of the PVT system was found to be 0.55. The thermal performance of the system was 47% during the zero reduce temperature. The unglazed PVT polymer collector could replace the conventional PVT collector, which encountered problems such as high cost, weighting issues, and corrosion.

Heat transfer equipment has been used in many different domestic and industrial applications. There has been a concentrated effort to create a heat exchanger design that will reduce energy requirements while saving materials and other costs. Increasing the effective heat transfer surface area or creating turbulence are two common ways to improve heat transfer and hence lower thermal resistance. The thermal Performance Factor is the ratio of the difference in heat transfer rate to the difference in friction factor and serves as a metric to assess the efficiency of heat transfer enhancement tech

Environmental conditions are considered an important factor influencing asphalt pavement performance. The addition of modifiers, both to the asphalt binder and the asphalt mixture, has attracted considerable attention in potentially alleviating environmentally induced pavement performance issues. Although many solutions have been developed, and some deployed, many asphalt pavements continue to prematurely fail due to environmental loading. The research reported herein investigates the synthetization and characterization of biobased Phase Change Materials (PCMs) and inclusion of Microencapsulat

A ubiquitous assumption in educational and psychological assessments is that student performance reflects ability or knowledge of what is being tested. Despite this assumption, in practice, student test performance reflects a mix of ability (knowledge) and effort. “Effort” refers to a range of motivational, dispositional, and energetic factors that contribute to student performance and that are distinct from ability (knowledge). Difficulties in operationally defining and measuring the degree of effort that students put forth in any assessment undermine the optimal use of assessment data. In th

One of the factors that affects energy consumption in buildings is the level of control that occupants have over their environment, as well as their adaptive behaviour. The aim of this study was to focus on the adaptive clothing behaviour pattern, and to analyse its impact on energy consumption when integrated into a dynamic energy prediction tool. A questionnaire survey was conducted in an office building to collect the occupant behaviour data. The occupant clothing levels and the window opening behaviour were integrated into the dynamic energy performance prediction software, IDA ICE. The re

Building energy and environmental efficiency is presently one of the most important research subjects due to global climate change and the actual geopolitical situation. Residential buildings should provide a comfortable environment for the occupants while they spend up to 90% of their life indoors. Moreover, a comfortable indoor environment should be provided efficiently and affordably. Thus, the examination of the correlated factors of buildings' energy efficiency and occupants' comfort is highly anticipated. This field can be analyzed using various methods, where computational simulations a

The necessity to improve broiler thermotolerance and live performance led to the following hypothesis: Appropriate comprehensive incubation treatments that include significant temperature management changes will promote angiogenesis and will improve acquisition of thermotolerance and carcass quality of heavy broilers through epigenetic adaptation. It was based on the following questions: 1. Can TM during embryogenesis of broilers induce a longer-lasting thermoregulatory memory (up to marketing age of 10 wk) that will improve acquisition of thermotolerance as well as increased breast meat yield
