A Project Report On AIR CONDITIONER ’’ WINDOW TYPE Submitted By JOEL A. OOMMEN Air Conditioner Window Type: [pic] . An air conditioner is an appliance‚ system‚ or mechanism designed to extract heat from an area via a refrigeration cycle. In construction‚ a complete system of heating‚ ventilation‚ and air conditioning is referred to as "HVAC." Its purpose‚ in a building or an automobile‚ is to provide comfort during either hot or cold weather. History: In 1820‚ British

State Heat Transfer laboratory were to study the rates of heat transfer for different materials of varying sizes‚ to develop an understanding of the concepts of forced and free convection and to determine the heat transfer coefficients for several rods. These objectives were met by heating several rods and allowing them to cool through free convection in air‚ free convection in water and forced convection in water- while monitoring their change in temperature over change in time. Seven heat transfer

Techniques of Waste Heat Recovery Waste heat recovery is being more used more and more often today as it is becoming more effective‚ due to increasing energy prices‚ technological developments and a decrease in equipment costs. Heat recovery can be classified into three main strategies: recycling energy back into the process‚ recovering the energy for other onsite use and using it to generate electricity in combined heat and power systems. Once the system has been made as efficient as possible before

Heat resistance of endospores of Bacillus pumilus Abstract Spore suspension of Bacillus pumilus was inoculated into universal bottles containing sterile distilled water in water baths at temperatures of 85°C‚ 90°C and 95°C. At specific time intervals‚ a sample was removed and spread on nutrient agar plates. The number of colonies formed was used to determine the D-value and z-value. The D-value for 85°C is 64.1 minutes‚ 25.7 minutes for 90°C and 8.2 minutes for 95°C while the z-value is 11

Second International Conference on Emerging Trends in Engineering and Technology‚ ICETET-09 Adsorption Air-Conditioning (AdAC) for Automobiles Using Waste Heat Recovered from Exhaust Gases A C Deshpande‚ R M Pillai Abstract- According to a cautious estimate‚ approximately 10% of the energy available at the crankshaft in a diesel operated vehicle is used for operating the compressor of the vehicle’s air-conditioning system. This is a huge loss if one takes into account the fact that the thermal

of the metal was determined by the heat energy calculations. The heat capacity that was found matched closely to that of the lead. There were several possible sources of error that could be found throughout the lab. Some of the main errors as seen in question 7 that could have affected the results of the lab were the amount of water transferred with the hot metal‚ the metal cooling off as it was transferred from the calorimeter‚ the calorimeter lost heat to the surroundings as it was stirred

2013 01_A3_ 20 years from now I chose the technology of Refrigeration to think about twenty years from now. A refrigerator Is a common household appliance that consist of a thermally insulated compartment and a heat pump ( mechanical‚ electronic‚ or chemical) that transfers heat from inside of the fridge to its external environment so that the inside of the fridge is cooled to a temperature below the ambient temperature of the room. A refrigerator is a common essential technology apart of our
