A vacuum or pressure refrigerator for storing containers having one-way valves and maintaining contents thereof under vacuum or pressure within a specific temperature range. Upon receiving an input that the door is closed, a refrigerator controller is adapted to cease operation of the cooling device and initiate a vacuum or pressure cycle. The vacuum or pressure cycle includes evacuating at least a portion of or pressurizing the air inside the compartment, operating the pump until a desired degree of vacuum or pressure is attained and terminating pump operation. The one way valves then evacuate or pressurize the containers. The controller is also adapted to subsequently initiate a cooling cycle, the cooling cycle commencing when it is determined that the temperature is above an upper set point and to operate the cooling device until the temperature reaches a desired lower set point, at which time the cooling cycle is terminated.
