摘要： Disclosed in the present application are an economizer and a refrigeration system comprising same. The economizer comprises: an outer shell that internally comprises a heat exchange cavity and a gas-liquid separation cavity; and a heat exchange tube bundle provided in the heat exchange cavity. The economizer is configured to enable refrigerants from a condenser to be subjected to heat exchange in the heat exchange cavity first, and then to be subjected to gas-liquid separation in the gas-liquid separation cavity after passing through a first-stage throttling device, such that gas refrigerants flow out of a gas outlet of the gas-liquid separation cavity, and liquid refrigerants flow out of a liquid outlet of the gas-liquid separation cavity. According to the economizer of the present application, the heat exchange cavity and the gas-liquid separation cavity are provided in the shell, the gas-liquid separation function of the economizer can be achieved, the heat exchange function of a subcooler can also be achieved, such that the structure of the two-stage compression refrigeration system with the function requirements of the subcooler can be more compact.

摘要： A vibration frequency adjustment system, comprising a vibratable component (102), at least one counterweight (401, 402), at least one drive device (407, 408), and a controller (307). The vibratable component (102) is configured to be connected to a vibration source (101). The vibration source (101) has an operating frequency range, and the vibratable component (102) has a natural vibration frequency. The at least one counterweight (401, 402) is configured to be movable along the vibratable component (102). The at least one drive device (407, 408) is configured to enable the at least one counterweight (401, 402) to be maintained at or moved to various counterweighting positions (421, 422, 423) on the vibratable component (102). The controller (307) is communicatively connected to the at least one drive device (407, 408). The vibration frequency adjustment system is used for a variable-frequency screw unit so as to reduce the vibration of an exhaust pipe.
