The temperature is a quantity associated with notions of heat, measurable by a thermometer. From a physics point of view, it is a scalar quantity related to the internal energy of a thermodynamic system such as air.
It is directly related to the part of internal energy known as kinetic energy, which is the energy associated with the movement of air particles, either in a translational, rotational or vibrational sense. As this movement increases, the kinetic energy also increases, so the object, in this case the air, is hotter and therefore its temperature is higher. When the movement of these particles decreases, the temperature also decreases, reaching even absolute zero, in which the movement of the particles is zero.
Temperature sensors: types and operation
A sensor is an object capable of detecting physical or chemical quantities called instrumentation variables, which can be light intensity, temperature, distance, acceleration, etc. The most commonly used Room Temperature Sensors is the thermo polar sensor. It is made up of very simple mechanisms made up of two metallic materials of a different nature joined by joints called cold junction and hot junction. The degree of temperature that these junctions detect generates a potential difference closely dependent on the nature of the materials. The blackhawk supply thermal sensor transforms this potential difference into an electrical signal.
When temperature sensors are used in natural ventilation systems
These measure the temperature inside and outside the home. The difference between the two determines the air flow that must be introduced into the building. When natural ventilation is not sufficient to achieve acceptable levels of comfort throughout the year, it is necessary to use mechanical conditioning systems. In these cases, the temperature sensor analyzes two temperature levels or “set points”, one below the temperature required for heating (for example 21º C), and the other above the temperature required for air conditioning. The house in summer (for example 23ºC). From there, the ventilation system defines the priorities: if the temperature is above 23ºC, depending on the difference in temperatures between the exterior and the interior,auxiliary air conditioning system. In the event that the temperature drops below the heating level (22ºC), the heating system will start to activate.
