An electronic expansion valve, a heat exchange system, and a control for controlling an electronic expansion valve. The electronic expansion valve includes: a valve body; a first temperature sensor configured to detect an evaporator temperature Teva; a second temperature sensor configured to detect a compressor inlet temperature Tsue; a third temperature sensor configured to detect a compressor outlet temperature Tdis; a fourth temperature sensor configured to detect a condenser temperature Tcon; and a controller, which is associated with the first temperature sensor, the second temperature sensor, the third temperature sensor and the fourth temperature sensor, and which adjusts an opening degree of the valve body based on temperature signals from the first temperature sensor, the second temperature sensor, the third temperature sensor and the fourth temperature sensor.
