AMBIENT TEMPERATURE: KEY CONCEPTS AND ITS ROLE IN COLD CHAIN PACKAGING
Ambient temperature refers to the air temperature in the surrounding environment, essentially the temperature of the air where people or objects are located. It is a critical physical parameter that influences various natural phenomena, industrial processes, and human activities. This article explores the definition, measurement, influencing factors, application areas, and the crucial role of ambient temperature in cold chain temperature-controlled packaging. 1. Definition of Ambient Temperature Ambient temperature is the temperature of the air in the surrounding environment, serving as a fundamental physical quantity that describes the state of thermal energy. It is typically expressed in degrees Celsius (°C) or Fahrenheit (°F). Ambient temperature impacts not only climate and weather but also biological processes, chemical reactions, mechanical operations, and more. 2. Measurement of Ambient Temperature There are several methods to measure ambient temperature: Liquid Thermometers: Mercury Thermometers: Utilize the thermal expansion properties of mercury to measure temperature. Alcohol Thermometers: Use alcohol’s thermal expansion, suitable for low-temperature measurements. Electronic Thermometers: Thermistors: Measure temperature based...
