ABSTRACT:

The wet-bulb temperature is an important psychrometric property and accurate measurements are essential for testing and rating of various types of Heating Ventilating Air Conditioning and Refrigeration (HVACR) equipment. The goal of the research project is to develop guidelines for measurement of wet bulb temperature and comparing with thermodynamic wet bulb temperature. Wet Bulb Temperature needs to measure which is as much as equal to thermodynamic wet bulb temperature. For measurement of wet bulb temperature an aspirated psychrometer and globe thermometer is designed and developed. The research will provide the basis for improvements in ASHRAE Standard 41.6-1994, Standard Method for Measurement of Moist Air Properties. The outcomes are the precautions to be taken during the measurement and providing guidelines which are used to avoid error in measurement of wet bulb temperature.
