The key to energy saving lies in control and management. To play a dramatic role in the energy consumption are the systems HVAC. L'HVAC is an acronym that collects the household or business systems most hungry for electricity. Proper management of systems HVAC it would save up to 67% on energy costs.
HVAC is an English acronym that stands for "Heating, Ventilation and Air Conditioning", Therefore, the acronym HVAC contains all the heating, ventilation and air conditioning systems. Equipment that dissipates a large amount of electrical energy belongs to this category. Sometimes the acronym can be accompanied by an R, in which case we will also speak of refrigeration.
HVAC - R
Heatin - heating
Ventilation - ventilation
Air Conditioning - air conditioning
Refrigeration - refrigeration
Commercial building owners could save on average, 38% of their energy expenditure if they decided to implement systems control policies HVAC. This is stated by the researchers of the US Department of Energy of the PNNL.
According to a recent report, the efficiency of the systems HVAC could be increased with the design of "air chambers”Which act as economizers. In doing so, a air conditioner it will not always have to recreate cold air with its "compressor", but the fresh air of the room can be used to cool the entire building.
Another strategy to apply to systems HVAC more closely relates to ventilation. "Speed controls" could be installed which would slow down the rotational movement of the fan when a certain amount of air has been cooled or when a precise temperature has been reached. Today, unfortunately, the ventilation systems do not have any management equipment and continue to ventilate with the same speed regardless of the cooling achieved.
In the field ofHVACAs far as heating is concerned, thermostats are very popular. For air conditioners and ventilation systems, there are control elements on the market but they are not as widespread as thermostats. The report's authors hope that their analysis will encourage producers and consumers to conduct more "Controlled".
“The potential savings derived from the implementation of a control system for air conditioners are enormous " says Srinivas Katipamula, the PNNL engineer who conducted the study. He then pointed out that the estimated savings for the commercial buildings vary widely based on the energy prices of the area of residence. In the United States, the most expensive area is San Francisco, where savings of 67% have been estimated. In Italy, the cuts on company bills could be even higher!
Advanced control systems forHVAC, are a clear example of how much a company policy based onenergy efficiency.
