Definitions

• the present invention relates to a freezer for temporary freezing of separate cooling elements in the form of flexible plastic sheetings which enclose several separate, closed container spaces enclosing cooling medium, such as water, intended to be freezed in order to emit cold for cooling purposes in a utilization condition outside the freezer, which freezer is provided with a freezing-compartment for storage and freezing of the cooling elements.
• a freezer for temporary freezing of separate cooling elements in the form of flexible plastic sheetings which enclose several separate, closed container spaces enclosing cooling medium, such as water, intended to be freezed in order to emit cold for cooling purposes in a utilization condition outside the freezer, which freezer is provided with a freezing-compartment for storage and freezing of the cooling elements.
• a freezer which is characterized in that the freezing-compartment is provided with, on the one hand, one or more suspension devices for suspension of the cooling elements which are spread out in the freezing-compartment and, on the other hand, a device for outflow of refrigerant against the outside of the cooling elements in the freezing- compartment for freezing of said cooling elements, wherein the suspension devices for each cooling element are arranged above the device for outflow of refrigerant.
• Fig. 1 shows the freezer according to the invention in an embodiment, wherein a cover associated therewith is removed
• the freezer according to the invention consists of a lower part 1 and an upper part 2 or cover, which jointly enclose a freezing-compartment 3, which is kept insulated against the environment by means of heat insulating walls, on the one hand a bottom 4, a gable wall 5 and sidewalls 6, 7 and on the other hand a partition wall 8 and the upper part 2.
• the insulation is for example constituted by a plastic having a satisfactory heat insulating capacity, i.e. a satisfactory coefficient of heat passage.
• the partition wall 8 separates a separate space 9 which is permanently in connection with the environment via an opening 10 in the bottom of the freezer.
• the upper part 2 is in utilization condition fixedly and tightly attached to the lower part 1.
• the upper part 2 is articulately attached to the lower part 1 by means of a pivot means 17, more precisely at the upper section of a sidewall 6.
• the upper part 2 is provided with a locking device 18 at, for example, its opposite side.
• FIG. 20 A cooling element 20 is also indicated in Fig. 4. Examples of cooling elements are shown in Figs. 5 and 6.
• the freezer is provided with a freezing device, comprising an injection device 28 for a refrigerant.
• a hose 29 (which is shown partly broken in Fig. 2), the injection device is connected or connectable to a refrigerant supply, for example a pressure chamber for a refrigerant, such as carbon dioxide, which pressure chamber preferably is situated outside the freezer.
• the coil 30 is not constituted by a cooling coil in the traditional sense and is therefore not provided with any return part but is closed in its further end 38.
• the coil is provided with a number of outlet ports 39-46 for the refrigerant.
• the outlet ports 39-46 are provided with an opening for each straight coil section 47, 48 between the curved coil sections 49, 50, i.e. between both opposite walls 6, 7 of the freezer.
• the openings are essentially arranged in the middle of the straight sections, i.e. in the middle of the freezing-compartment 3.
• the openings are schematically shown as slit formed openings, but trials have shown that the openings advantageously can be circular and for example have a diameter of 0,3 mm.
• the openings are arranged on the upper side of the cylinder-shaped envelope surface of the coil, i.e. turned upwards, towards the suspension devices 19 and the upper part 2.
• the straight coil sections 47 are situated straight below each suspension member 27 associated therewith, i.e. so that a coil section 47 is provided for each suspension member 27.
• the refrigerant flows in an upwards direction in the space 55, 56, along the inside of the cooling elements up to the suspension bars, that is to say the central part of the cooling elements, where it turns in order to flow downwards along the sides of the cooling elements down towards the inside 37 of the bottom 4 of the freezer, see arrows regarding the flow in Fig. 4.
• the valve is kept open for a short time which is adjusted to the amount of water which shall be freezed. For example, the valve is kept open and the outflow or the discharge of refrigerant occurs in approximately one minute in the event of a weight of water of up to approximately 2 kg, e.g. in two intervals of 20 seconds each with an intermission of approximately half a minute.
