Abstract Solar water heating systems have been widely used around the world. However, exposure to sunlight can overheat device, affecting efficiency and durability of system. This article proposes an adaptive deck controller that protects system from overheating without compromising availability domestic hot water. heaters are considered one most effective ways reduce a home’s carbon footprint....

This Future weather dataset is used for assessing the risk of overheating and thermal discomfort or heat stress in the free running buildings. The weather files are in the format of .epw which can be used in the building simulation packages such as EnergyPlus, DesignBuilder, IES, etc.

A solar concentration system formed by two holographic cylindrical lenses is proposed. It redirects part of the incident solar spectrum towards a PV cell, concentrating only the cell’s most efficient wavelength range, while the rest is transmitted, not causing overheating. Simulations with oneand two-axes tracking are carried out.

J. Piątkowski The Silesian University of Technology, Faculty of Materials Science and Metallurgy, Katowice, Poland R. Wieszała, The Silesian University of Technology, Faculty of Transport, Katowice, Poland The paper presents microstructure tests of alloy AlSi17Cu5. In order to disintegrate the primary grain of silicon the so-called time-temperature transformation TTT was applied which was based...

25 In ground-nesting birds egg colour and appearance may have evolved due to opposite 26 selection pressures. Pigmentation and spottiness make the eggs darker and have been 27 suggested to improve camouflage. However darker and more spotted eggs may reach 28 higher temperatures when not attended by adults and receiving direct sunlight, which 29 may be lethal for embryos. Some authors suggested ...

This study compares the overheating risk of eight typical Danish residential buildings for today and future climate scenarios. The includes four single-family multi-family houses, various renovation strategies, two occupancy loads. Building performance simulation is employed to conduct 3012 simulations (using IDA-ICE), comparison potential conducted using Indoor Overheating Degree (IOD). Result...

Global warming is resulting in higher summer indoor temperatures the severe cold region and of China, this affecting thermal comfort. Local building design codes consider these regions as cool summer, do not phenomenon overheating or propose countermeasures. This paper studied possibility residential buildings areas. It suggested alleviating using external horizontal shading, discussed how to i...

A condition of half normal voltage imposed on a refrigerator compressor will result in overheating of the motor if the ~ondition persists for an extended time. The line current and heating of the compressor shell are similar to the conditions which exist under peak loading. A thermal overload which allows compressor operation under peak conditions and still prevents overheating when half normal...
