Description of the Related Art As one type of cooling / heating system generally used, there is an absorption type cold / hot water generator for directly burning heavy oil, kerosene, city gas or the like to extract cold or hot water. When a plurality of absorption-type cold / hot water generators are used for cooling and heating in one building, the number of operating units is managed and controlled in order to perform cooling and heating efficiently.

いう把握が困難であった。However, the absorption type cold / hot water generator originally has a large variation in the coefficient of performance depending on the product. Further, for example, if the cooling operation time is long, the coefficient of performance is reduced due to the scale of the cooling water adhered to the condenser, and the output is reduced, resulting in insufficient cooling or poor fuel efficiency. Therefore, it has been difficult to determine how many absorption-type cold / hot water generators can be used to obtain the required cooling / heating effect.

Also, each component such as a sensor must be replaced as needed. If the coefficient of performance of each absorption type chilled / hot water generator is not always measured, the maintenance period is extremely short for some absorption type chilled / hot water generators, and it is difficult to grasp the appropriate maintenance time. There was a problem that is. Further, there is a problem that a heavy-load countermeasure machine having a long service life is expensive.
