TECHNOLOGICAL CONNECTION BETWEEN DUAL SENSING AND RELATIVE HUMIDITY

TECH & MACHINES, ZLOGS  /   /  By LG HVAC
Humidity is something we are used to hearing about in daily weather reports. High humidity contributes to that stuffy, muggy feeling we experience in a sauna or on damp summer day. Conversely, low humidity makes the air feel arid and dry. The most commonly used method for measuring humidity is known as relative humidity. This relative humidity is the best indicator for how the atmosphere feels at any given temperature, and by detecting and controlling the relative humidity, we can provide more comfortable and efficient air conditioning systems. LG has developed a dual sensing technology that just does that and they have applied this technology to their new line of Multi V 5 air conditioners.

 

Humidity effects how we perceive temperatures

 

Relative humidity refers to the amount of moisture in the air compared to how much moisture the air is able to hold at a certain temperature. To understand this concept better, let’s also define the term ‘absolute humidity’. Absolute humidity is the amount of moisture in the air regardless of the air temperature and the warmer the air, the more moisture it can contain. Therefore, relative humidity is the ratio of current absolute humidity versus the highest possible absolute humidity at a given temperature. The relative temperature at any given temperature can have a significant effect on how we perceive the temperature. The higher the relative humidity, the higher the temperature can feel to us. A relative humidity of 0% at 26.6℃(80℉) feels like 25.4℃(77.8℉) and a relative humidity of 100% at 26.6℃(80℉) feels like 30.6℃(87.2℉). Therefore, monitoring relative humidity can make an important difference when controlling the temperature of a room.

A technology known as dual sensing in the HVAC world makes it possible to simultaneously detect both temperature and relative humidity. With this technology, an air conditioning system is able to determine how the temperature of a room feels and adjust the temperature accordingly. This not only ensures a heightened level of comfort for those in the building, but also allows the system to run more efficiently. A more efficient system means a reduction in energy consumption and energy costs. Effectively management of these factors is beneficial for both building operators and occupants.

 

 

LG Electronics has harnessed this breakthrough technology and implemented it into their Multi V 5 system air conditioning solution. Sensors are built into the outdoor units and the remote controls of the indoor units to detect both temperate and relative humidity outside and inside the building. Precise monitoring of these measurements allows the LG Multi V 5 to accurately adjust the workload of the air conditioner to create a more comfortable environment and conserve energy. This accurate workload control is particularly valuable for minimizing energy consumption in the summer when temperatures and humidity levels change drastically throughout the day. LG Electronics is breaking new ground in the HVAC industry and leading the way with this next-generation technology.
