reduce temperature of inlet air. Several different inlet cooling methods are currently employed in various systems. The techniques of reheating‚ regenerating‚ inter cooling require installation of additional heavy machinery which is not economically feasible. Apart from these power augmentation techniques‚ which could be applied to existing gas turbines‚ can be divided into two main categories. The first category includes inlet air cooling technique and the second involves techniques based on injection

Optimization of Room Air Conditioning with Desiccant Wheel 1. Introduction Desiccant air conditioning technology is an emerging alternative air conditioning technology having many advantages over conventional VAC system. Desiccant cooling technology is free from CFCs‚ can be operated with low grade energy (heat energy) and capable of precise control of latent heat load of conditioned space. This eco friendly and energy saving method of air conditioning has drawn interest of many researchers over

the water-rich secretion of the eccrine glands. Maximum sweat rates of an adult can be up to 2-4 liters per hour or 10-14 liters per day‚ but is less in children prior to puberty. Evaporation of sweat from the skin surface has a cooling effect due to evaporative cooling. Hence‚ in hot weather‚ or when the individual’s muscles heat up due to exertion‚ more sweat is produced. Animals with few sweat glands‚ such as dogs‚ accomplish similar temperature regulation results by panting‚ which evaporates

Sufficient Homemade Air Conditioner Introduction and Background of the Study As day time is starting to become more and more unbearable‚ as fans would only constantly stir the hot sticky air S around‚ so the researchers ended up in choosing this topic. The researchers chose this topic mainly because of the hot weather here in the Philippines. The constant high temperature was the reason this came up to the researchers’ minds. This

Australian Ectotherms and Endotherms- temperature regulation Part A :Types of Temperature regulation 1. Write down the meaning of the terms endotherm and ectotherm. Consult a textbook if necessary. a. endotherm Endotherms are animals that can maintain a constant internal body temperature. For instance mammals and birds are true endotherms that can maintain a constant internal body temperature b. ectotherm Ectotherms are animals that are not able to regulate their body temperature or in simple

water‚ preventing creatures from being crushed by the ice‚ and also keeping them from freezing as well. Not only does the ice absorb heat making waters cooler‚ but it also insulates this heat creating a livable habitat for the animals below. Evaporative cooling and high heat of vaporization are more important properties of water. Evaporation is the conversion of a liquid to a gas‚ while high heat of vaporization is the heat needed to convert the liquid to a gas. When water is heated‚ its molecules

determine the volume flow rates of air to be pushed into the ducting system and the sizing of the major system components. Approaches to Temperature Control Temperature control in an air conditioning system is achieved by passing the air through the cooling or heating coil‚ which may use any of the following approaches: 1. Vary the temperature of air supplied to the space while keeping the airflow rate constant. This is the basic constant volume‚ variable temperature approach. 2. Vary the airflow

plays a large role in determining our comfort level. If the relative humidity is 100 percent‚ it means that water will not evaporate -- the air is already saturated with moisture. Our bodies rely on the evaporation of moisture from our skin for cooling. The lower the relative humidity‚ the easier it is for moisture to evaporate from our skin and the cooler we feel. HUMIDIFICATION & DEHUMIDIFICATION Let’s go with the notion that temperature is actually a container. Let’s call it a

of warm air forms agains the surface. Moving air disrupts the boundary layer‚ allowing for new‚ cooler air to replace the warm air against the surface. The faster the wind speed‚ the more readily the surface cools. The speed of cooling has different effect on inanimate objects and biological organisms. For inanimate objects‚ the effects of wind chill is to reduce any warmer objects to the ambient temperature more quickly. It cannot‚ however‚ reduce the temperature of these
