彩经网 The compressor and the electronic expansion valve (EEV) are integrated in a control loop. When the cold air requirement changes, the EEV takes on the task of precision adjustment by varying the degree of opening within a few seconds. If this precision control is no longer sufficient, the cooling capacity is adapted by way of the compressor speed. Due to the short control response times, the system always works in the optimum operating range, making it even more efficient.
