Basics of Refrigeration – Temperature (1) I. Overview There are many places in refrigeration technology where temperature needs to be measured, such as the suction temperature and exhaust temperature of compressors, the temperature of lubricating oil, and the temperature of cooling water. The numerical scale for temperature is simply called a temperature scale. There are mainly three commonly used temperature scales: Celsius, Kelvin, and Fahrenheit. 1. The International System of Units designates Celsius as the practical temperature scale. 2. The International System of Units designates Kelvin as the base temperature scale. 3. The Fahrenheit scale has finer divisions and is more widely used in Europe and America. Question: Please write down the conversion formulas between Celsius and Kelvin, as well as between Celsius and Fahrenheit. Answer: ℃ = K + 273.15; F = 1.8 * ℃ + 32 ============================== Premium promotion: Daily questions on refrigeration-related mechanical equipment – their value and functions https://bbs.hcbbs.com/thread-2848974-1-1.html; Internal training materials for screw refrigeration compressor manufacturers https://bbs.hcbbs.com/thread-2850090-1-1.html
Kelvin temperature = 273.15 + Celsius temperature. Fahrenheit temperature = Celsius temperature × 1.8 + 32
Kelvin temperature = 273.15 + Celsius temperature. Fahrenheit temperature = Celsius temperature × 1.8 + 32
Kelvin temperature = 273.15 + Celsius temperature. Fahrenheit temperature = Celsius temperature × 1.8 + 32
The conversion formula between Celsius and Kelvin temperatures is T(K) = 273.15 + t(°C). The conversion formula between Celsius and Fahrenheit temperatures is t°F = 5/9 × t°C + 320°F
The conversion relationship between Celsius and Kelvin temperatures is: T = t°C + 273.15 K ≈ t°C + 273 K. The conversion relationship between Fahrenheit and Celsius temperatures is: t°F = 5/9 t°C + 32°F
Conversion between Celsius temperature and Kelvin temperature: Celsius temperature + 273 = Kelvin temperature; Conversion between Celsius and Fahrenheit temperatures: Celsius temperature = (Fahrenheit temperature – 32) ÷ 1.8.
Celsius temperature = Kelvin temperature + 273.15°C Fahrenheit = 32 + 1.8×Celsius temperature
Kelvin temperature = 273.15 + Celsius temperature. Fahrenheit temperature = Celsius temperature × 1.8 + 32
