The phrase "124 units per year in refrigerators" appears to be incomplete or lacks context. Without additional information, it's challenging to determine its specific meaning. However, I can speculate on possible interpretations based on common usage in the context of refrigerators and manufacturing:
Production or Sales Volume: It could refer to the number of refrigerators a company manufactures or sells in a year. For example, if a refrigerator manufacturer produces 124 units per year, it means they manufacture and sell 124 refrigerators annually.
Energy Consumption: It could also relate to the energy consumption of a refrigerator. Some refrigerators' energy efficiency is measured in units, such as kilowatt-hours (kWh) per year. So, 124 units per year might indicate the average energy consumption of a particular refrigerator model over a year.
Service or Maintenance Metrics: In the context of maintenance or repair, it could represent the number of refrigerator units serviced or maintained by a technician or a service center in a year.
To provide a more accurate interpretation, please provide additional context or clarify the specific area or industry where this phrase is being used.
