PROBLEM TO BE SOLVED: To facilitate the system management of a heating and cooling machine such as absorption chiller/heater or compression refrigerating machine. SOLUTION: A monitoring sensor 52 (56, 60) is provided adjacently to at least one of various flowmeters 50 (54, 58) used for evaluating performance of a heating and cooling machine body, a control board 62 for heating value calculation/performance valuation is connected to this monitoring sensor, and an operation/control board 64 is connected to the control board 62. A signal transmitted from the monitoring sensor is converted to a numerical value, and the capability of the heating and cooling machine is normally monitored by use of the temperature measured by temperature sensors T1-T8 of the cooling and heating machine body and the value of the flow rate signal converted to the numerical value. By providing the function of converting the signal from the monitoring sensor to a numerical value such that it is used for flow rate calculation, the monitoring and evaluation of the capability during operation can be performed.
