HVAC Split System - Hygrometer: To measure Humidity.


HVAC Split System - Is Used to Measure the Humidity.



When buying an air conditioner often overlook many of the functions that these teams bring incorporated; air conditioning console not only gives us the ability to counter the high temperatures experienced during the summer months.


Many air conditioners have a hygrometer, this is a primary tool that is used to measure humidity, has in turn a sensitive organ which is composed of organic materials that change the length of its volume when moisture the temperature varies.


 


Before hygrometers consoles exist in air conditioning, were used for making them, animal membranes, hair, fibers, wood and other materials artificial kind.


The hygrometer is also known as a hydrometer, the unit of measurement is given in percentage, this instrument was used in early hair when humidity increased the same absorbed water vapor and increased its length and vice versa. The air conditioning hygrometers have a hygrostat, which are responsible for measured by a lever system that length changes are performed.

The air conditioning hygrometers also often called condensation hygrometers and they are based on the fact that the steam makes its condensation on cold bodies; maintaining a cold capsule, and causing the water vapor to pass through it, it is condenses. The hygrometer measures the temperature at which this phenomenon occurs and knowing the temperature of ambient humidity can be determined. The hygrometer uses the property of certain materials to change their electrical resistance when moisture so does, in this process employs metal electrodes coated with salts that property, which allows this device to estimate changes in humidity.


 


This type of hygrometer is based on the conductivity of lithium chloride with ambient moisture, and its measurement is made using a proper connection bridge as the instrument note making changes very rapidly. But hygrometers are not only able to measure the degree of humidity, but also a certain kind of gas, this is done by using sensors that receive and then indicate its variation.

This instrument also supports certain ramifications that are used in air conditioning consoles but many do not know, including psychrometers find, used to determine moisture by differentiating the temperature with humidity and temperature ordinary.


 


The hygroscope consoles is employed in technology and consists of a string of hair, which is twisted with a greater or lesser degree depending on the ambient moisture capture; said bundle of hair type moves a needle indicator which determines the proportion of the moisture, but it does not give us a percentage measurement.

The absorption hygrometer instead hygroscopic chemical substance used, they absorb and give off moisture, according to the circumstances around them. Moisture artifacts such air conditioners usually vary grasp absolute humidity, relative humidity and humidity.


 


Humidity is known as the amount of water vapor containing air, moisture can be expressed in absolute or in relative humidity. The absolute humidity is also the amount of vapor that the air presents but this can be expressed in grams and has a specific volume, the higher the temperature, the more water vapor the air can store.


 


Finally we have the relative humidity, this is the moisture that has an air mass in relation to the maximum absolute humidity are performed may be any type of condensation, thus maintaining the same conditions of temperature and atmospheric pressure. This is the most common way of expressing the amount of humidity and the extent of expression is percentage.
