<p>Provided are a refrigeration system (1) and a control method therefor. The refrigeration system (1) comprises: a compressor (10), where the compressor (10) is provided with an air intake passage, an air exhaust passage, and a compressing mechanism, the compressor is used for compressing and discharging a refrigerant, and the compressing mechanism is provided with a fluid compression chamber; a condenser (20), where the condenser (20) is arranged downstream to the air exhaust passage; an electronic expansion valve (30), where the electronic expansion valve (30) is arranged in a passage between the downstream of the condenser (20) and the fluid compression chamber, and is used for controlling the volume of the refrigerant that is introduced into the compressor (10); and, a control device (40), where the control device (40) receives a signal of the compressor (10) and outputs a control signal to the electronic expansion valve (30), and the control device (40) is used for controlling an initial step frequency of the electronic expansion valve (30) on the basis of whether or not the control device (40) is being powered up for the first time.</p> |
