Per il calcolo EER, è necessario conoscere la vostra altezza e peso in unità metriche. ‘I have a 1.5-ton AC or a 1-ton AC in my house.” What does this signify? Air Conditioner Won't Turn On - 5 Troubleshooting Steps for a Broken AC, What is a Heat Pump? For example, mini-split systems only use the SEER rating, instead of the EER rating. Nonetheless, HVAC experts from AHRI (Air-Conditioning, Heating, and Refrigeration Institute) recommend using a simple and universal formula to calculate SEER from given EER. A unit’s energy efficiency ratio is the ratio of cooling energy to the amount of energy (wattage) required to power your unity. SEER also uses average US household energy expenditures in its calculation. 11 * Analysis from Trane Acoustics Program (TAP) EER • BTU = British Thermal Unit: a unit measurement of heat. A unit’s EER rating can also be used to directly compare a Carrier Infinity Series air conditioner to a Lennox Signature Series, for instance, but in short, EER is a more technical, objective means of rating an air conditioner’s efficiency, but doesn’t take into account seasonal changes.
