    respective space(s)‚ and then the chilled water is re-circulated back to the chiller to be cooled again. These cooling coils transfer sensible heat and latent heat from the air to the chilled water‚ thus cooling and usually dehumidifying the air stream. A typical chiller for air conditioning applications is rated between 15 to 1500 tons (180‚000 to 18‚000‚000 BTU/h or 53 to 5‚300 kW) in cooling capacity. Chilled water temperatures can range from 35 to 45 degrees Fahrenheit or 1.5 to 7 degrees Celsius

    as Phase Diagrams By _________________ _________________ Material Science Lab #11 Report Introduction The purpose of this lab is to obtain the cooling curves for tin‚ lead and various alloys of these two metals. A phase diagram will be generated from these cooling curves. When a material is heated by adding energy at a constant rate‚ the temperature of the material will increase linearly with time‚ provided a phase transformation does not occur. As temperature of the sample becomes

    countries‚ a strong increase in the demand for building cooling and air-conditioning is detected and predicted for the following decades (by a factor of 4 in 2020). The reasons for this general increase are manifold‚ such as an increase in comfort habits‚ currently still low energy costs‚ architectural trends like an increased fraction of glazed areas in buildings and last but not least lowly changing climate conditions. This rising demand for cooling and air-conditioning in buildings involves unfavourable

    Introduction: In industry‚ a heat exchanger is used to cool down streams for temperature sensitive processes. The now hot cooling water is useless to the plant unless something is done to cool it down. In industry‚ cooling water towers are used to bring the water back down to a sufficient level . In a cooling tower‚ outside atmospheric air is flowed through a “column” while the hot water sprayed into the system. Since air is never at full saturation of water (unless it is raining)‚ some of the hot

    in a metabolic chamber‚ and measurements were taken for elevated metabolism at 35 degrees Celsius. An hour later‚ measurements were taken again at 24-26 degrees Celsius. Minimal endothermy was determined in both experiments (Bennett 2000). The three sub factors of solar energy absorption include convection‚ conduction‚ and radiation. Convection is a continuous circulation of liquid or air that transfers thermal energy from hot to cold surfaces (Reece 2014). The process of heat gain is evident when
