Degree Celsius

Degree Celsius

The degree Celsius or degree Celsius (in symbol in ° C), is the unit of a temperature measurement scale, named after the Swedish astronomer Anders Celsius (1701 - 1744), who proposed it for the first time in 1742.

The Celsius scale fixes the melting point of ice in a mixture of water saturated with air at 0 ° C and the boiling point at 99.974 ° C under standard pressure conditions (1 bar, a little less than one atmosphere, pressure in the one that the water boils at 100 degrees centigrade).

Originally conceived by the Celsius scale had the boiling point of water at…

Degree Kelvin

Degree Kelvin

The Kelvin is the temperature unit of the International System. The Kelvin is one of the seven basic units of temperature. Its symbol in the international system of units is K. The Kelvin scale is a thermodynamic (absolute) temperature scale where the absolute zero, the theoretical absence of energy, is zero (0 K). This unit is named after the British physicist, mathematician and engineer William Thomson (1824 - 1907), who was later named Lord Kelvin. Lord Kelvin wrote about the need for a "thermodynamic temperature scale".

To express the temperature difference or the interval, the use…

Temperature

Temperature

Definition of temperature: The temperature is the thermodynamic magnitude that shows the thermal energy of one body in relation to another.

Although the definition of temperature is simple and concise, you can explain what the temperature is in a more extensive way:

What is the temperature?

Temperature is a physical quantity of matter that quantifies the common notions of heat and cold. The objects of low temperature perceive them cold, while objects of higher temperatures we consider them warm or hot. This physiological sensation of cold and heat is generated…

Degree Fahrenheit

Degree Fahrenheit

The Fahrenheit degree (° F) is a temperature unit proposed by Gabriel Fahrenheit in 1724.

On the Fahrenheit scale, the melting point of water is 32 degrees of temperature, and the boiling point is 212 degrees. A difference of 1.8 degrees Fahrenheit equals that of 1 degree Celsius. Fahrenheit established the zero temperature (0 ° F), the freezing point of a 50% mixture of salt (ammonium chloride) and ice, and as 96 ° F, he took the temperature of the blood (he used that of the horses ). The figure 96 may seem an odd measure, but in principle the scale contained only twelve…

Evacuated Tube Solar Collector

Evacuated Tube Solar Collector

A solar collector of evacuated tubes is a type of solar panel that uses solar thermal energy. The finality of solar collectors is converting solar radioation into thermal energy.

This renewable solar energy system uses a type of solar panel consisting of linear collectors housed in evacuated glass tubes.

The evacuated tube solar collector consists of a set of cylindrical tubes. The tubes are formed by a selective absorber, located on a reflector settlement and surrounded by a transparent glass cylinder.

The vacuum has been made between the transparent outer tube and…

Low-Temperature Solar Thermal Energy

Low-Temperature Solar Thermal Energy

Low-temperature solar thermal installations are considered those installations of solar thermal energy that provide useful heat at temperatures below 65 ° C through solar energy.

A low-temperature solar thermal installation consists of solar collectors, two water circuits (primary and secondary), heat exchanger, accumulator, expansion vessel and pipes.

The circulation of water inside the circuits can be obtained by thermosiphon, taking advantage of the density difference of the water at different temperatures or by means of a circulation pump. Although with a circulation…
