Since the energy consumption has become one of the crisis of modern buildings, modeling the Iranian past architecture patterns could be helpful. The shopping streets as one of the main sectors consuming energy locate near the open spaces it seems, therefore, they need more thermal comfort. However, using passive techniques, the Iranian traditional bazaars architecture solved the problems regard...

Using the analytic estimates developed for the emittance diagnostic channel for the finalstage cooling experiment, we conclude that diagnostics for both an initial-stage cooling experiment, and for the targetry experiment could be performed with a bent solenoid of 1.25 T field strength. The solenoid bore would need to be at least 35 cm for the initial-stage cooling experiment, and at least 50 c...

Cooling times for various autoclave loads were recorded using thermocouples. Loads which may be encountered during normal laboratory working require between 17 and 174 minutes to cool to 100 degrees, C and up to 260 minutes to cool to 95 degrees C. Such long cooling times had an adverse effect on nutritive properties of bacteriological culture medium. Observations are made on some factors which...

Nonuniformity of inlet temperatures often produces “false-positives” that will increase overall supply airflow (higher fan energy). Nonuniformity could also result in cooler supply temperatures (lower chiller efficiency). And if you use nonuniform control mechanisms, you will not be able to target cooling where it is needed, which means you will probably overcool servers that don’t need the coo...

By increase in the power of computer systems and enhanced power of the components and their temperature, including the central processing unit (CPU), cooling just by the air is not effective and there is need for more powerful systems to cool down and increase the power of the cooling system. In this article simulation of the heat exchanger material of the fluid cooling system has been studied ...

Description Background – Given the increasingly stringent cooling demands in mid to high-end electronic packages, there is a need for high cooling power density yet robust cooling solutions. Convective liquid cooling using micro-channel heat sinks in single-or two-phase operation has received a lot of attention in recent research. Whereas single-phase cooling is simpler and more robust, two-pha...

With the availability of waste heat from various power stations and industrial processes, adsorption cooling systems offer advantages compared to mechanical vapour compression systems. The dynamic modelling of such system is very important as it predicts the system performance with time in terms of bed temperature, pressure, cooling capacity and coefficient of performance. Therefore there is a ...

The telecommunication industry is concerned about the energy costs of its operating infrastructure, and the associated greenhouse gas emissions. At present, more than half of the total energy consumption of data centers is for the power and cooling infrastructure that supports the storage and communication equipment. One method of reducing energy consumption is an approach called ―free air cool...

Evaporative cooling system concepts proposed over the past century for engine thermal management in automotive applications are examined and critically reviewed. The purpose of the review is to establish evident system shortcomings and to identify remaining research questions that need to be addressed to enable this important technology to be adopted by vehicle manufacturers. Initially, the ben...
