摘要

To provide a method for determining a load factor of heat source devices, a simulation system of a heat source facility and the like capable of accurately deriving load factors of respective heat source devices in a heat source facility with a mix of constant flow pumps and variable flow control.SOLUTION: A plurality of pumps includes at least one constant flow pump and at least one variable flow pump. In a method for determining load factors of heat source devices, a total variable flow rate of the variable flow pumps is repeatedly calculated until the same becomes larger than 0 by converting the constant flow rate pumps with low operation priorities into the variable flow pumps. When the load factors of heat source devices exceed the maximum load factors thereof, outlet temperatures of the corresponding heat source devices are changed to the outlet temperatures in the case of operating the same with the maximum load factors until the load factors of all the heat source devices become equal to or less than the maximum load factors thereof while concurrently performing repeated calculation of the load factors on the basis of average outlet and inlet temperatures and the calculated load factors are applied to the corresponding heat source devices.SELECTED DRAWING: Figure 8
