Cooling

widely used in traditional cooling systems. These refrigerants accelerate the depletion of the Earth’s ozone layer. Therefore, adsorption air-conditioning technology attracted much attention recently as an alternative solution due to its advantage of environmental friendliness. This system as it powered by waste and/or solar heat can help to reduce required energy and thermal pollution. This paper presents an overview of research which have been carried out on adsorption cooling systems powered by waste

dissipation in a building in order to improve the indoor thermal comfort with low or nil energy consumption is termed as Passive Cooling. (Santamouris & Asimakoupolos, 1996, Samuel, et al, 2013). This approach works either by preventing heat from entering the interior (heat gain prevention) or by removing heat from the building (natural cooling) (Limb, 1998). Natural cooling utilizes on-site energy, available from the natural environment, combined with the architectural design of building components

prospect of losing their hair. DigniCap, a cooling system that chills patients' scalps to reduce chemo hair loss, has been approved by the Food and Drug Administration (FAD) for breast cancer. The DigniCap, made by Sweden's Dignitana AB, is the first version officially cleared by the FDA. The company will lease the device to cancer centers to use as their patients come in for chemotherapy (1). Introduction Some chemotherapy drugs can damage your hair cells. Cooling of the scalp is a proven approach to

represents the Performance Evaluation of Hybrid Air Conditioning system using Indirect Evaporative Cooling Approach. The experimentation has been done with various cycle of operation viz. ventilation, mixed, with different dessicant materials and dessicant wheel speed. In desiccant wheel, if the regeneration temperature increases, the loads gets completely separated, thereby performance of cooling coil improves a lot i.e. 70% to 80%. However, system performance decreases due to increased power at

RAID HARD DRIVE: RAID is actually a Redundant Array of Inexpensive Disk that is used to increase storage capacity and performance of a system. RAID consists of multiple hard disk drives, work as a single drive unit. All the writing as well as reading configuration operations perform at once on all drives. The speed of read/write data streaming is one of the bottlenecks for hard drive. Its main advantages are: • Storage • Reliability • Speed Logical units operate and configure incoming arrays from

airy and crispy texture (Nath and Chattopadhyay, 2008; Mariotti et al., 2006). Process for making starch-based puffed products includes gelatinization of starch, cooling, drying, and then explosive expansion (Hoke et al., 2007). After starch gelatinization, retrogradation of starch molecules, amylose and amylopectin occurred during cooling and aging of the pastes (Perdon et al., 1999; Ji et al., 2007; Mariotti et al., 2009). The amylose-amylopectin ratio, which commonly reported in term of amylose

PASSIVE SOLAR ARCHITECTURE INTRODUCTION:1 The last two decade has witnessed a severe energy crisis in developing countries especially during summer season primarily due to cooling load requirements of buildings. The energy consumption in buildings is quite high and is expected to further increase because of improving standards of life and increasing world population. Air conditioning use has increasingly penetrated the market during the last few years and greatly contributes in the upsurge of

para. 1). It was created somewhat of a minor breakdown in the cooling circuit, which caused the temperature in the primary coolant to rise and the reactor to automatically shut down. The valve failed to close and the instrumentation did not reveal what was happening, causing the primary coolant to drain away. The chain of the events during the Three Mile Island Accident During the course of events, the relief valve on the reactor cooling system opened as it was supposed to within seconds of the shutdown

It is safe to conclude that heating and cooling appliances provide residents with various forms of comfort. During the winter, heating appliances provide residents with the basic biological need of warmth. In the summer, cooling appliances deliver coolness to the inside of homes, businesses, and other industrial or institutional buildings. For Toronto's heating and cooling appliance users, luckily, recent years of industrial and economical progressions have allowed them to use appliances that are

Along with electricity and water, district cooling constitute a new form of energy service. District cooling is measured in refrigeration ton which is equivalent to 12000 BTU's per hour. Refrigeration Ton is the unit measure for the amount of heat removed. Refrigeration Ton is defined as the heat absorbed by one ton of ice (2000 pounds) causing it to melt completely by the end of one day (24 hours). District cooling systems can replace any type of air conditioning system, but primarily
