Nowadays, almost every building required a cooling system and most of them use active cooling, which normally operates using electricity generated from non-renewable fossil fuel. To achieve comfort, it is possible to utilize the natural environmental conditions to partially replace the active...

The provision of low cost cooling is challenging due to high energy costs and increasing heat dissipation volumes from data centers. In Australia, with the introduction of emissions trading scheme, the cost of energy with carbon origin is expected to increase. In order to reduce cooling costs,...

This paper presents a review study on the effects of sun tracking and cooling systems. So far, many studies (and case studies too) have been analyzed and evaluated in the literature. Existing studies show that sun tracking system is significantly affecting energy generation capacity of...

The compound-structure permanent-magnet synchronous machine (CS-PMSM) is a power-split device which can enable the internal combustion engine (ICE) to operate at optimum efficiency during all driving conditions by controlling its torque and speed. However, the CS-PMSM has more serious...

Solar thermophotovoltaic (STPV) is a light-electricity conversion system consisting of a solar concentrator, an emitter, a filter, PV cells and the cooling system. This paper is aimed at establishing a method for both purposes of design and performance analysis of the STPV device, which consists...

This paper describes the performance of an ejector cooling system driven by solar energy and R134a as working fluid. The system operating in conjunction with intermediate temperature solar collector in Athens, is predicted along the 5 months (May–September). The operation of the system and the...

An implementation of a cooling system with a loop heat pipe for thermal control of supercomputers is considered. For this purpose two copper–water loop heat pipes (LHPs) with an effective length of 400 mm and ID/OD diameters of the vapor lines of 3/4 and 4/5 mm correspondingly were designed...

The cooling systems of rapidly growing Data Centers (DCs) consume a considerable amount of energy, which is one of the main concerns in designing and operating DCs. The main source of thermal inefficiency in a typical air-cooled DC is hot air recirculation from outlets of servers into their...

Improvements in cooling system efficiency are required in modern internal combustion engines (ICE). Optimal thermal management presents several advantages in terms of lower pump mechanical power, reduced friction losses and shorter warm-up time, which result in reduced fuel consumptions and CO2...

Various technologies as can be seen in vernacular architecture especially in Japanese traditional buildings are reviewed and the ways and means to have those technologies applied to the design of modern architecture are discussed with some examples. It is stressed that the vernacular...
