Definitions

  • the invention relates to a device for compensating for the pressure differences occurring during the defrosting of the evaporators of the cooling unit at predetermined time intervals between a temperature-controlled cooling or freezing room and the atmosphere surrounding the boundary walls of such a cooling or freezing room.
  • Such a device is intended to prevent excessive pressure or vacuum being created in the rooms where the temperature is comparatively low.
  • such devices are required in cooling chambers or pressure chambers in which the evaporators of the cooling units have to be defrosted at predetermined time intervals. The temperature increase required for defrosting leads to an increase in pressure.
  • flaps are not suitable for refrigerated or deep-freeze rooms with a large volume, for example 70,000 to 80,000 m 3 .
  • a large volume for example 70,000 to 80,000 m 3 .
  • spring-loaded closure elements do not always close tightly, so that there is some air exchange even during normal operation, ie not only during the defrosting process.
  • the invention seeks to remedy the problem and proposes a solution to the problem, even in refrigerated or deep-freeze rooms with a large volume of up to 70,000 to 80,000 m 3 , to provide a device with which pressure equalization is perfectly possible.
  • the device according to the invention is characterized by a free opening provided in the boundary wall of the refrigerator or freezer, the dimensions of which are adapted to the volume of the refrigerator or freezer and which is closed by a pivotable, thermally insulated flap-like door and is provided with an electromechanical drive which is provided with the control of the defrosting process is coupled such that the flap opens automatically at the end of the defrosting process and closes again automatically after a predetermined time.
  • the device Through the device according to the invention, a completely free connection between the refrigerator or freezer compartment and the atmosphere surrounding it is established in the critical periods, ie in the time before the evaporator fans start again after defrosting, and thus any pressure fluctuation inside the refrigerator - or freezer absolutely prevented, so that stresses on the walls and especially the Ceiling construction can no longer occur. Due to the presence of an electromechanical opening and closing drive, the dimensions of the flap-like door can be chosen so optimally that it is perfectly suitable for the desired purposes even with comparatively large volumes.
  • a heatable frame is preferably inserted into it.
  • a strip or pendulum curtain can be provided in a further embodiment of the invention before the opening.
  • FIG. 1 closes a refrigerator or deep-freeze room 3, the boundary wall 1 of which has an opening 2, the dimensions of which are indicated schematically by the dashed line in FIG. 1 and fully in the other figures.
  • a frame is seated which consists of an inner part 4 set thermal insulation 5 and an outer part 6, which can also be seen in Fig. 1.
  • a circumferential heater 11 is also provided on the frame part 6, which prevents the flap-like door 9 from freezing to the frame part 11.
  • a rod 13 is pivotably mounted on the frame part 6 via a joint 12, which rod is connected via a joint 14 to a crank arm 15 which can be driven by a motor 16 sitting on the door 9.
  • a crank arm 15 which can be driven by a motor 16 sitting on the door 9.
