air temperature. This is the variable volume reheat approach. Approaches to Humidity Control Humidity control in a conditioned space is done by controlling the amount of water vapor present in the air in the space. When relative humidity at the desired temperature set-point is too high‚ dehumidification is required to reduce the amount of water vapor in the air for humidity control. Similarly‚ when relative humidity at the desired

Physical Properties of Water Aim : 1. To comprehend and learn about the factors that affects the boiling rate and the boiling point of water. 2. To evaluate the moisture content of foods. 3. To observe the relationship of different relative humidities of the surroundings towards the sensory properties of foods.

environment. Desiccant cooling technology is initiated to control the relative humidity level of the environment. A generic model of the evaporative cooler is constructed using direct evaporative cooling method and solid desiccant dehumidification method. The model was installed in the testing environment. The results show that the evaporative cooler is provided the sufficient level of thermal comfort to the people changing relative humidity slightly. 1. Introduction This paper based on the research

The purpose of owning a house in the modern age is mostly associated with the idea that we have to settle down with a family of our own. The truth behind the ideology is that homes have been essential to primitive human survival; it has never been about family. Without shelter‚ our bodies would be exposed to the natural climate and other dangers which could result in sickness such as hypothermia. In shorter terms a house was originally used as a defense method that would combat natural threats. (Funk

Before completing this lab‚ one must understand that “all air has some moisture in it‚ but how wet the air feels depends not just on the amount of moisture but also the temperature of the air” (Lab Intro Given). In the meteorology career‚ terms such as “dew point and “relative humidity” are used. The following are

OBSIDIAN HYDRATION There are two ways of Obsidian Hydration. One is to determine if the artifact is older or younger as the other is a calendar date of AD/BC being used. The decision of which one to use is relative or absolute dating depends on the environment’s condition. The dating of Obsidian Hydration artifacts‚ which is based on the fact that a freshly made surface of obsidian will absorb water from it’s surroundings to form a measurable hydration layer. For example‚ cracking of the lava

Abstract The phenomenon of evaporative cooling is a common process in nature‚ whose applications for cooling air are being used since the ancient years. In fact‚ it meets this objective with a low energy consumption‚ being compared to the primary energy consumption of other alternatives for cooling‚ as it is simply based in the phenomenon of reducing the air temperature by evaporating water on it. This process can be an interesting alternative to conventional systems in these applications where
