Abstract

PURPOSE:To make it unnecessary to switch the sensor connection at the time of switching between cooling and heating by determining the number of operating units from the absolute value of the difference between detected values of heating medium temperature at the inlet and outlet of a heat exchanger which are detected by sensors, and outputting the drive signal to the equipment according to the number of units so determined. CONSTITUTION:An inlet temperature sensor T2 and an outlet temperature sensor T1 are respectively connected to the heating medium inlet and outlet of a heat exchanger H, and a temperature compensating sensor TC is further connected thereto. Signals from the sensors T1, T2, TC and a heating medium flow meter M are inputted to a control device 1. The control device 1 determines the absolute value of difference between the sensors T1 and T2 in accordance with a given program, and, from the absolute value of difference, the number of operating units is determined. It then outputs the equipment drive signal according to the number of units so determined. By this constitution, the switching of the sensor connection becomes unnecessary at the time of switching between cooling and heating.
