energy bill

HVAC units are big consumers of energy in the majority of installations in a range of sectors. They can account for 60% of the electricity bill in tertiary sector buildings such as hotels, hospitals, shopping centres, industrial and office blocks. The way forward to finding solutions that achieve energy savings in this field is based on access to information. As a result, Indoorclima is developing the Climate management Big Data, offering vital information on the operation of chiller and rooftop units from manufacturers worldwide. Having knowledge of their actual operation in a wealth of situations (both those inherent to the units and those relating to the installation or location) is providing the keys to developing the necessary algorithms to be able to parameterise each installation in terms of optimal performance and thereby reduce energy consumption from 20% to 50% depending on the installation.

HVAC installations have a low level of energy management. One major issue is the lack of the control over large output units that are usually located in regions with difficult access, and the preventative maintenance itself that is very basic, generally reduced to the minimum regulatory requirement. As a reference, of the total sales of HVAC units in 2012, only 15% corresponded to regulation and control systems. And this, in sectors where HVAC units consume more than 3,000,000 kWh/year, representing disproportionate and unnecessary energy costs.

And this has provided the basis for the work of Indoorclima in its search for a solution whose main aim is to save energy in HVAC installations. Read more…
