摘要： A refrigerator and method utilize a pair of tandem evaporators to provide cooling for both a compartment and an ice making system of a refrigerator. An upstream evaporator in the pair of tandem evaporators provides cooling for a compartment such as a freezer, fresh food, flexible cooling, or quick cooling compartment, while a downstream evaporator is in fluid communication with the upstream evaporator to receive a portion of the air cooled by the upstream evaporator and further cool the received portion for use in cooling one or more components of the ice making system.

摘要： An improved heat pump apparatus configured to transfer heat by circulating a refrigerant through a cycle of evaporation and condensation without the need to run a defrost cycle—the No-Frost Heat Pump (NFHP)—is provided. The NFHP is configured with a four-way valve, a suction accumulator, and a compressor to pump and exchange a refrigerant between two heat exchange coil/coils—an outdoor heat exchange coil/coil (also known as the source coil) and an indoor heat exchange coil/coil (also known as the load coil)—in order to exchange heat between the indoor/outdoor heat exchange coils. The NFHP is further configured with a means for controlling hot gas discharge—the means comprising a discharge valve or a discharge gas injection valve configured to inject refrigerant into the outdoor heat exchange coil inlet/source coil, thereby preventing the formation of ice/frost on the surface of the coil while operating in heating mode at low outdoor ambient temperatures.

摘要： A method for controlling a refrigerator according to an embodiment of the present invention is characterized by comprising: a step for determining whether a defrosting period (POD) for defrosting a freezing chamber and a deep freezing chamber has elapsed; a step for, when it is determined that the defrosting period has elapsed, performing a deep cooling operation for bringing at least one among the temperature of the deep freezing chamber and temperature of the freezing chamber down to a temperature lower than a control temperature; and a step for defrosting the deep freezing chamber when the deep cooling operation is terminated, wherein, when the defrosting of the deep freezing chamber is started, a freezing chamber valve is closed to block cold air flow to the heat sink, the defrosting of the deep freezing chamber includes cold sink defrosting and heat sink defrosting performed after the cold sink defrosting is completed, and while the heat sink defrosting is being performed, a deep freezing chamber fan is driven to remove vapor generated during the cold sink defrosting.

摘要： A heat pump system including a charge compensator having a liquid line port for an inflow of a refrigerant into the charge compensator and for an outflow of the refrigerant from the charge compensator. The heat pump system further includes an isolation valve configured to control flows of the refrigerant to and from the charge compensator through a liquid line piping of the heat pump system based on whether the heat pump system is operating in a cooling mode, a defrost mode, or a heating mode, where the liquid line port is fluidly coupled to the liquid line piping of the heat pump system.

摘要： An augmented heat transfer system can be used to control the humidity of adjacent conditioned spaces by selectively absorbing latent heat energy from a relatively warm space, such as a loading dock, and discharging this energy in the form of sensible heat to an adjacent relatively cold space, such as a freezer served by the loading dock. This transfer of sensible heat energy into the cold space induces a vapor compression system to remove sufficient moisture from the cold space to avoid uncontrolled precipitation. At the same time, the process of removing moisture/latent heat from the warm space can also be used to reduce humidity in the warm space via condensation on a cold evaporator. Therefore, in operations where the warm space and the cold space are both nominally sealed from ambient air, such as an indoor loading dock serving a freezer, the augmented heat transfer system can eliminate uncontrolled precipitation in the freezer while also mitigating moisture ingress to the freezer from the dock space.

摘要： A refrigerator and a control method, device and system thereof are provided. The method comprises detecting and confirming that the cumulative running time of a compressor is no less than a running time threshold, and an ice maker is currently in a working state, and controlling the ice maker to perform an defrosting operation after a current ice making period is ended, the running time threshold being a time difference between the defrosting period of the refrigerator and the ice making period of the ice maker. The method allows avoiding defrosting in the ice making period, and therefore, the influence of defrosting on ice making of the ice maker can be reduced, the ice making efficiency and the ice making capacity if the ice maker can be effectively promoted, the ice making period is shortened, energy consumption is reduced, and produce reliability is improved.
