Method for a pressure-based determining of a product parameter in a freeze dryer, freeze dryer and software product

Methods are disclosed for the pressure-based determining of a product parameter in a freeze dryer, in particular a product temperature. At a point in time t.sub.START, a closing element as an intermediate valve between an ice chamber and a drying chamber of the freeze dryer is closed. Then, during a pressure rise occurring due to the sublimation pressure values (P.sub.1, P.sub.2, . . . ) are measured in the drying chamber. At a point in time t.sub.END then the closing element is opened. From the measured pressure values (P.sub.1, P.sub.2, . . . ) an approximation of a product parameter, in particular a product temperature T.sub.APPROX, is determined. The point in time t.sub.END is determined specifically for the measured pressure values (P.sub.1, P.sub.2, . . . ) such that the time span for which the closing element is closed depends on the determined pressure values and such that the time span is variable during a drying process.

UPRIGHT APPLIANCE DRAIN JUMPER
20210095912 · 2021-04-01 ·

A drain assembly for a refrigeration appliance in communication with an appliance drain. The drain collects condensate from an evaporator behind the rear wall of the cabinet and transfers the condensate to the drain assembly in the machine compartment of the refrigeration appliance. The drain assembly then transfers the condensate to an extension tube easily accessible to an operator. The drain assembly includes an inlet, a main body, and an outlet. The inlet is secured to the appliance drain and the outlet is secured to the extension tube. The main body also comprises a downward slope in between the inlet and the outlet. In one example, a vacuum relief system can equalize a pressure differential between an interior of the main body and an exterior environment.

REFRIGERATION APPLIANCE FAN

A refrigeration appliance includes a freezer compartment fluidly coupled to an ice maker compartment via an ice maker return duct. An internal sensor is positioned within the freezer compartment and configured to sense a first condition within the freezer compartment. An external sensor is coupled to said refrigeration appliance and configured to sense a second condition external to said refrigeration appliance. A return fan is positioned within the ice maker return duct. A controller is operably coupled to the internal and external sensors to receive sensed first and second conditions. The controller is configured to determine a differential between the sensed first condition within the freezer compartment and the sensed second condition external to said refrigeration appliance. The controller activates the return fan to blow air from the ice maker compartment into the freezer compartment in response to the differential.

REFRIGERATOR
