Thank you for visiting Airfridge.co.za, creating comfortable environments since 1995. Up to date we have installed 4000 units, completed 26 major projects and successfully completed 850 breakdowns – ontime. Our biggest project was at Protea Hotel where we installed 600 split air conditioning units. All our products and services carry a warantee from our suppliers.

Just an interesting thought.

Celsius is, or relates to the Celsius temperature scale. Degrees Celsius (symbol: °C) refers to a specific temperature on the Celsius temperature scale. The degree Celsius is also a unit increment of temperature for use in indicating a temperature interval (a difference between two temperatures or an uncertainty). “Celsius” is named after the Swedish astronomer Anders Celsius (1701 – 1744), who first proposed a similar system two years before his death. 

Until 1954, 0 °C on the Celsius scale was defined as the melting point of ice and 100 °C was the boiling point of water under a pressure of one standard atmosphere. Today, the unit “degree Celsius” and the Celsius scale are, by international agreement, defined by two points: absolute zero, and the triple point of specially prepared (VSMOW) water. This new definition also precisely relates the Celsius scale to the Kelvin scale, which is the SI base unit of temperature (symbol: K). Absolute zero—the temperature at which nothing could be colder and no heat energy remains in a substance—is defined as being precisely 0 K and –273.15 °C. The triple point of water is defined as being precisely 273.16 K and 0.01 °C. This definition does three things: 1) it fixes the magnitude of the degree Celsius as being precisely 1 part in 273.16 parts the difference between absolute zero and the triple point of water; 2) it establishes that one degree Celsius has precisely the same magnitude as a one kelvin; and 3) it establishes the difference between the two scales’ null points as being precisely 273.15 degrees Celsius (–273.15 °C = 0 K and 0.01 °C = 273.16 K).
