ABSTRACT

PSUCHRON-Psychrometric System

Purpose:-

    To obtaindesired Dry-bulb temperature, Wet-bulb temperature, Humidity, Dew point temperature, Specific enthalpy,  and other properties of air.  

Why should anyone care about the work we did?

Although the principles of Psychrometric apply to any physical system consisting of gas-vapor mixtures, the most common system of interest is the mixture of water vapor and air, because of its application in heating, ventilating, and air-conditioning and meteorology. In human terms, our comfort is in large part a consequence of not just the temperature of the surrounding air, but the extent to which that air is saturated with water vapor.

Many substances are hygroscopic, meaning they attract water, usually in proportion to the relative humidity or above a critical relative humidity. Such substances include cotton, paper, cellulose, other wood products, sugar, calcium oxide (burned lime) and many chemicals and fertilizers. Industries that use these materials are concerned with relative humidity control in production ++and storage of such materials.

In industrial drying applications, such as drying paper, manufacturers usually try to achieve an optimum between low relative humidity, which increases the drying rate, and energy usage, which decreases as exhaust relative humidity increases. In many industrial applications it is important to avoid condensation that would ruin product or cause corrosion.

Molds and fungi can be controlled by keeping relative humidity low. Wood destroying fungi generally do not grow at relative humidities below 75%.

Problem statement:-

  • Not available in any market at this scale cost and range.
  • Temperature controlling and constant level maintained in machine.
  • Wide range of 0-700 c
  • Controlling is very easy
  • Constant monitoring and controlling with use of computors
  • Automatic cut-off at any range.
  • Digital Indicators
  • Safety controlled electric configuration
  • Calibrate function
