摘要
A refrigeration system, comprising a compressor, a condenser (200), a throttle flow path (100), and an evaporator (300) connected in sequence, wherein a non-adjustable main throttle element (110,120) is disposed in the throttle flow path; and further comprising a bypass flow path (500), wherein the bypass flow path is connected to the throttle flow path respectively at the upstream and downstream of the main throttle element, and provided with an adjustable auxiliary throttle element (510) thereon; a liquid level sensor, disposed upstream and/or downstream of the throttle flow path, and configured to detect the liquid level; and a controller, wherein the controller is configured to control the opening of the auxiliary throttle element according to a liquid level signal from the liquid level sensor.
