AIR CONDITIONING SYSTEM SYSTEM DESCRIPTION


  1. GENERAL


    1. The air conditioning system has the following features:


      • In accordance with the temperature set using the temperature control switch, the air conditioning amplifier determines the outlet temperature based on the input signals from various sensors. In addition, corrections are added in accordance with the signals from the water temperature sensor to control the outlet air temperature.

      • Controls the blower motor in accordance with the airflow volume determined by the air conditioning amplifier based on the input signals from various sensors.

      • Automatically changes the outlets in accordance with the outlet mode ratio that is determined by the air conditioning amplifier based on the input signals from various sensors.

      • Checks the sensors in accordance with the operations of the air conditioner switches.

      • The air conditioning amplifier has the function of controlling the indicator lighting.
