Abstract: A method which allows the ejection of non-condensable gases, notably air, from a closed loop power generation process or heat pump system, is disclosed. A vessel in which a working fluid is absorbed or condensed can be separated from the power generation processes by valves. Residual gas comprising C02, non-condensable gas such as air, water and alkaline materials including amines may be compressed by raising the liquid level in said vessel. The concurrent pressure increase leads to the selective absorption of C02 by alkaline materials. In simpler embodiments, mainly air is removed from one- or two-component processes. Following the compression, non-condensable gas may be vented, optionally through a filter. The method is simple and economic as vacuum pumps may be omitted. The method is useful for any power generation and Rankine cycle, and particularly useful for the power generation process known as C3 or Carbon Carrier Cycle.

Abstract: A refrigerator has a storage compartment, a door for opening and closing the storage compartment, an ice-making machine and an ice storage compartment. The ice-making machine is used to produce an ice cube. The ice storage compartment is disposed below the ice-making machine, so as to accommodate an ice cube. The ice storage compartment has a discharge port. A movable blocking member and an ice-crushing cutter are located in the ice storage compartment. A distributor is located on the door and used to distribute the ice cube from the ice storage compartment to the outside. The ice storage compartment further includes an opening and closing mechanism for opening or closing the discharge port. Because the discharge port of the ice storage compartment can be closed, the ice-crushing cutter disposed above the discharge port will not be unconsciously touched, and a user is avoided from being hurt by the ice-crushing cutter.
