On-line operation energy efficiency monitoring and evaluation system and method for air conditioner

The invention relates to an on-line operation energy efficiency monitoring and evaluation method for an air conditioner. The method is characterized by comprising the followings steps: collecting parameters of the air conditioner connected with an intelligent socket and transmitting the parameters to a background service center by the intelligent socket; storing and analyzing the parameters by the background service center so as to obtain short-time energy consumption and/or long-time energy consumption of the air conditioner, and transmitting the short-time energy consumption and/or long-time energy consumption of the air conditioner to a browsing terminal for displaying. Air conditioner or machine room energy efficiency evaluation based on actual running is beneficial complement to a standard laboratory energy efficiency evaluation method, and actual energy efficiency evaluation of air conditioners of different types (variable-frequency or constant frequency) in different regions and different seasons can be obtained. A good assisting effect on an energy efficiency label authentication system is realized, and manufacturers can no longer only consider economic benefits to delusively mark energy efficiency, and cannot cheat consumers for some performance indexes, such as minimum temperature, which cannot reach standards.
