What is Psychrometrics?
Psychrometrics is the measurement of water vapor and heat in an air sample. It is used in the refrigeration industry, the design of clean rooms, certain manufacturing processes, and for theoretical applications. Psychrometry is a branch of thermodynamics and deals with terms like dry-bulb temperature, wet-bulb temperature, specific heat, and relative humidity. An understanding of psychrometry is a prerequisite for precise control of the humidity of contained environments. The key concept in psychrometrics is the relationship between wet-bulb temperature, dry-bulb temperature, and relative humidity. Psychrometrics applies the well-understood relationships between humidity and temperature in air to practical problems. In psychrometrics, dry-bulb temperature refers to the temperature of air as measured by a conventional thermometer. Wet-bulb temperature is measured with a device called a hygrometer, designed to measure the temperature in a way that reflects the cooling properties of evapo
