Given the explosive growth of data, scalability and fault tolerance have become a fundamental challenge for data center network structures. Temperature in data centers significantly affects the failure ratio of high-speed network devices. Various types of air distribution schemes influence the temperature of network equipment differently, and the cooling cost in data centers dominates the overa...

PURPOSE Analysis of incidence of fungal pathogens in air of Department of Dermatology, Venereology and Allergology of Medical University in Wrocław. MATERIAL AND METHODS Materials for the tests were: the air samples in front of the building, corridors, library, lecture hall, and mycological laboratory. The air pollution was determined using SAS SUPER 100. Humidity and temperature were evaluat...

The cost affiliated with energy consumption of a conventional air conditioner is so high, an average salaried person cannot afford it. 5.8 m x 4.5 3.6 room used for the assessment, in which Inverter/VRF and Conventional conditioning systems are separately to attain set temperature 25 OC weather Hyderabad, Pakistan. Through simulated results, May has highest use, 467 kWh 310 inverter conditionin...

Currently, convective heating with a heat-pump system, which has high energy efficiency, is popular for room heating. However, it is possible that energy savings using convective heating can be further improved using heat pumps that service both occupied and unoccupied spaces. Moreover, convective heating increases vertical temperature gradients in a room; thus, it is hard to say whether occupa...

This paper accentuate upon the application of Heating, Ventilation and Air-conditioning system in supporting the manufacture of quality pharmaceutical products. The HVAC system supply conditioned air to coveted areas of indoor surroundings to stimulate and maintain required temperature, humidity, ventilation and air-purity. The Good Manufacturing Practice for HVAC services embraces number of is...

regarding the green chemistry's goals, dicationic magnetic room temperature ionic liquid open up new avenue to introduce an amazing and efficient system for facilitating catalyst recovery in different organic reactions. ability of this dicationic magnetic room temperature ionic liquid catalyst in the one-pot three-components condensation reaction of benzil, aromatic aldehyde, and ammonium aceta...

tetrahydropyranylation of alcohols and phenols, acetylation of aldehydes and n-boc protection of amines are efficiently catalyzed by melamine trisulfonic acid (mtsa). all reactions were performed at room temperature in good to high yields.

The dehumidifier is a key component in liquid desiccant air-conditioning systems. Analytical solutions have more advantages than numerical solutions in studying the dehumidifier performance parameters. This paper presents the performance results of exit parameters from an analytical model of an adiabatic cross-flow liquid desiccant air dehumidifier. Calcium chloride is used as desiccant materia...
