Abstract

PURPOSE: To diagnose the efficiency of heat source apparatuses with a required accuracy by a method wherein an instantaneous efficiency is operated by an efficiency operating formula based on the data (input power, cooling capacity, amount of heat of cooling water, pressure of a condenser, pressure of an evaporator and the like) at respective parts of the heat source apparatuses which are the objects of diagnosis while a time average efficiency of the instantaneous efficiencies is operated to compare the time average efficiency with a reference efficiency and diagnose whether efficiency deterioration exists or not.
CONSTITUTION: When data, such as an input power (w), a room cooling capacity (q), the amount of heat of cooling water (e), a condenser pressure (pc), an evaporator pressure (pt) and the like are inputted into an efficiency diagnosing device 2, an efficiency operating unit 4 operates the ratio of an actual performance coefficient to the performance coefficient in a reverse Carnot's cycle at each time steps and an instantaneous efficiency as a time series data is operated. Next, an average processing unit 5 averages the instantaneous efficiencies, operated by the efficiency operating unit 4, in a predetermined step section to operate a time average efficiency while an efficiency deterioration diagnosing unit 6 inputs the time average efficiency, operated by the average processing unit 5, to compare it with a reference efficiency, stored in a reference efficiency data file 7, whereby the efficiencies are diagnosed whether the deterioration of the same exists or not.
