4.2.1.3 Pressure Sensor In addition to the temperature and humidity sensors, pressure sensors have been located near the outdoor unit to control the speed of the compressor. Working together with the electronic expansion valve, the overall refrigerant flow is controlled by the variable-speed compressor that is linked to the pressure sensor. Table 16 shows a number of pressure sensors. Table 16 Pressure sensors
