Abstract
A management system for vehicle air-conditioning and a method of managing the same are provided. Changes of a temperature in a vehicle from various environmental information, between a standard for showing a comfortable environment in the vehicle and actual environment information, are recognized to identify abnormalities occurring in components at an early stage and to appropriately judge the necessity and urgency of maintenance. A management system of vehicle air-conditioning includes an air-conditioning controller that predicts abnormalities of components of the refrigeration cycle by comparing a temperature in the vehicle obtained when the refrigeration cycle is actually driven with a preset temperature in the vehicle that constitutes a standard.
