Definitions

  • the present invention relates to a refrigerator and freezer with at least one refrigerant circuit which comprises at least one evaporator and at least one compressor.
  • refrigerator-freezer combinations with at least one refrigerator compartment and with at least one freezer compartment are known from the prior art, which include at least one refrigerator part evaporator and at least one freezer part evaporator.
  • the refrigerant circuit of such a known device is shown schematically in Figure 3 reproduced.
  • the refrigerator compartment evaporator is identified with the reference number 10 and the freezer compartment evaporator, which is connected downstream of the refrigerator compartment evaporator 10, with the reference number 20.
  • the refrigerant circuit shown also includes the suction pipe identified by the reference numeral 30, which is located between the freezer compartment evaporator 20 and the compressor 40 and is guided to the compressor 40 by the refrigerant.
  • the condenser 50 is arranged downstream of the compressor 40. Downstream of the condenser 50 is the solenoid valve 60, from which a line section leads around the refrigerator compartment evaporator 10 and a line 70 into the area of the inlet of the freezer compartment evaporator 20.
  • This bypass line 70 can thus be opened or closed accordingly by activating the valve 60. It is thus possible, depending on the valve position, to allow refrigerant to flow through the refrigerator compartment evaporator 10 and then the freezer compartment evaporator 20 or to feed the refrigerant directly to the freezer compartment evaporator 20 through line 70 and bypassing the refrigerator compartment evaporator 10.
  • the refrigerant collector used in known devices also has the disadvantage that it is filled with refrigerant while the compressor is idle. As a result, when the compressor is started, part of the non-evaporated, that is to say liquid, refrigerant reaches the suction pipe 30 and possibly the compressor 40, which is undesirable.
  • the refrigerant in the collector only contributes slightly to the refrigeration capacity of the device, which has disadvantages with regard to the efficiency of the device.
  • a refrigeration device which has an evaporator with a plurality of plate-shaped heat exchanger elements, each of which is connected on the inlet side to a common supply line and on the outlet side to a common suction line.
  • the riser pipe is extended downwards beyond the connection points of the heat exchanger elements, this extension of the riser pipe serving as a separator for the liquid refrigerant.
  • the present invention is therefore based on the object of developing a device of the type mentioned at the outset such that it can be operated with a high level of efficiency.
  • At least one liquid separator is arranged between the evaporator and the compressor, which has at least one inlet and at least one outlet and which is designed and arranged in such a way that it prevents the inflow of liquid refrigerant into the suction pipe of the compressor.
  • the liquid separator according to the invention thus serves to prevent liquid refrigerant, ie refrigerant which has not changed into the gaseous state in the evaporator or which condenses again after flowing through the evaporator, from entering the suction line. This can prevent the problem of frost on the suction line.
  • the use of the liquid separator can prevent part of the non-evaporated refrigerant from being fed into the suction pipe and possibly also into the compressor when the compressor is started. Piston compressors, in particular, must not suck in any liquid refrigerant, as the liquid refrigerant can destroy the piston or cylinder head.
  • the present invention is not restricted to reciprocating compressors, but rather encompasses any desired types of compressor.
  • the liquid separator is arranged relative to the evaporator in such a way that the refrigerant located in the liquid separator runs back into the evaporator at least when the compressor is not in operation. This return of the liquid refrigerant takes place due to the force of gravity, so that the liquid separator is to be arranged above the evaporator.
  • the liquid separator is thus preferably arranged in such a way that it is not or only slightly filled with liquid refrigerant, at least during the compressor service life. It is therefore preferably provided that the liquid separator is arranged and designed in such a way that at least part of the refrigerant located in the liquid separator flows back into the evaporator during the compressor idle time. This can then evaporate in the evaporator and in this way contributes to the cooling capacity of the device.
  • the liquid separator is designed as an elongated body, preferably as a tubular element, or has one.
  • the liquid separator can have a round, oval or also angular cross section.
  • the liquid separator is arranged vertically and / or that its inlet is arranged on the underside and the outlet on the upper side of the liquid separator. When the compressor is in operation, the liquid separator is thus traversed from bottom to top, with the flow direction being able to run vertically or at an angle to the vertical.
  • liquid separator is formed by or has a tubular body, the longitudinal axis of the tube running vertically or essentially vertically. If the compressor is not in operation, this can be done in the liquid separator Any liquid refrigerants that are located flow back to the evaporator through the inlet arranged below, evaporate there at least partially and thus serve to increase the cooling capacity.
  • the device is a refrigerator and freezer combination, that the refrigerant circuit has at least one refrigerator compartment evaporator for cooling at least one refrigerator compartment and at least one freezer compartment evaporator for cooling at least one freezer compartment and that the liquid separator is arranged between the freezer compartment evaporator and the compressor is.
  • the present invention thus also relates, for example, to devices as shown in FIG Figure 3 are shown so that reference is made accordingly.
  • the liquid separator according to the invention is arranged between the freezer compartment evaporator 20 and the compressor 40. This has the task of preventing liquid refrigerant from getting into the area between the liquid separator and the compressor 40 or into the suction pipe 30 leading to the compressor 40.
  • the internal dimensions of the liquid separator can have, for example, a diameter in the range from 2 to 4 cm and / or a length in the range from 5 to 15 cm. These are only exemplary details that of course do not restrict the subject matter of the invention.
  • the liquid separator thus preferably has larger dimensions than a conventional refrigerant collector.
  • the liquid separator has a first section in the area of its inlet, in which the diameter increases in the direction of flow of the refrigerant, and in the area of its outlet has a second section in which the diameter decreases in the direction of flow of the refrigerant .
  • liquid separator with a conically widened inlet area and with a conically tapering outlet area is conceivable.
  • the inlet area is in connection with the pipe section coming from the evaporator and the outlet area with the compressor suction line.
  • the inlet is formed by a connection piece which protrudes into the interior of the liquid separator.
  • This connecting piece can be embodied in the form of a tubular piece or form a component of the line from the evaporator leading to the liquid separator.
  • the nozzle-shaped section has a plurality of openings in its side wall, ie not in the end region, for the entry of refrigerant into the interior of the liquid separator.
  • the nozzle or said line has a plurality of openings in its wall through which the refrigerant reaches the interior of the liquid separator.
  • These openings can be designed as holes or slots, for example.
  • one or more grids or fabric-like structures are arranged in the liquid separator. These have the task of preventing flow noises in the area of the liquid separator.
  • the reference numeral 100 denotes a liquid separator according to the present invention.
  • the liquid separator 100 consists of a pipe section 105 which is cylindrical and has a constant cross section over its length. This pipe section 105 is followed by an inlet section 110 of increasing diameter and an outlet section 120 of decreasing diameter.
  • the liquid separator 100 has a first opening in the area of its inlet section 110 and a second opening in the area of its outlet section 120. Pipe sections of the lines 200, 300 protrude into these openings, the line 200 leading from the evaporator to the liquid separator 100 and the line 300 leading from the liquid separator 100 to the compressor.
  • the line 300 thus represents the suction line of the compressor.
  • the flow direction in the illustrated liquid separator 100 is from bottom to top. This means that the refrigerant flows through the line 200 and the line connector, which forms the end region of the line 200 and which protrudes into the interior of the liquid separator 100, into the latter.
  • the drain line 300 suction line
  • the outlet line 300 unlike the inlet line 200, does not protrude into the interior of the liquid separator 100.
  • grids 400 or metal mesh 500 are arranged both downstream of the inlet and upstream of the outlet.
  • these grids or fabrics can be straight or also curved.
  • both a grid 400 and a metal mesh 500 can be arranged in the interior of a liquid separator. These can be spaced from one another in the flow direction of the refrigerant, ie in the longitudinal direction of the liquid separator, as shown in FIG Figure 1 emerges.
  • the grating is curved, as is also shown in FIG Figure 1 is shown.
  • the metal mesh 500 is curved in such a way that it is arched upwards, that is to say towards the grid 400.
  • the metal mesh 500 is also designed to be curved and its bulge likewise protrudes towards the grid 400. Due to the fact that in this case the metal mesh 500 is arranged downstream of the grid 400, the metal mesh 500 is bent or curved downwards.
  • more than one grid or more than one metal mesh can also be arranged, these preferably being spaced apart from one another in the direction of flow.
  • the refrigerant When the compressor is in operation, the refrigerant reaches the interior of the liquid separator through the front end area of the connecting piece. Liquid refrigerant is retained or, when the compressor is operating, collects around the lower area of the liquid separator and is therefore not in contact with the outlet which is arranged at the top. Thus, liquid refrigerant can be prevented from entering the suction pipe 300.
  • FIG 2 shows a further embodiment of the liquid separator according to the invention, the structure of which is essentially that in Figure 1 shown corresponds.
  • the inlet connector which can be formed by the end region of the line 200 or can also form part of the liquid separator itself, has several holes 205 or also several slots 207. These holes 205 or slots 207 can be distributed in the longitudinal direction and / or in the circumferential direction of the connecting piece.
  • the second pattern from the left points in Figure 2 four holes, which are distributed in the circumferential direction, preferably offset by 90 °.
  • These holes can have a diameter of 1 to 5 mm and preferably in the range of 2 to 4 mm and particularly preferably a diameter of 3 mm.
  • the holes can be at the same height on the connecting piece or can also be arranged offset in the height direction.
  • the second pattern from the right in Figure 2 corresponds in this respect to the aforementioned pattern, with additional provision here that three holes are arranged one above the other in the longitudinal direction of the connecting piece, so that a total of 12 holes result.
  • the right pattern in Figure 2 shows an embodiment with slots 207, with four slots 207 offset in the circumferential direction of the connecting piece, each having a width in the range from 1 to 2 mm, preferably 1.5 mm and a length in the range 10 to 30 mm, preferably 20 mm.
  • the refrigerant passes through these holes 205 or slots 207 into the interior of the liquid separator when the compressor is in operation. Additionally for this purpose, the end region of the pipe or the line 200 is closed at the end. If it is not in operation, refrigerant can flow back into the evaporator through these openings.
  • the supply line and / or discharge line to or from the liquid separator can form an integral part of the liquid separator itself or can be formed by the lines 200, 300 that lead or from the evaporator, in particular from the freezer compartment evaporator, to the liquid separator 100. lead from this to the compressor.
  • the liquid separator 100 brings about overfilling phenomena and frosting of the suction line, which according to FIG Figure 1 Connected above the liquid separator 100 or formed by the line 300, a significant improvement is achieved.
  • the relatively large diameter of the liquid separator 100 leads to a significantly lower flow rate.
  • liquid separator or its inlet and outlet are designed in such a way that the liquid refrigerant is pressed against the outer walls of the liquid separator and is returned to the evaporator due to the force of gravity.
  • the in Figure 2 holes 205 or slots 207 of the connecting piece shown are used.
  • the refrigerant that has flown back from the liquid separator 100 can evaporate and thus overall contributes to improved device efficiency.
  • the liquid separator 100 has a significant energy advantage compared to known devices.
  • the liquid separator is in a refrigerant circuit as it is from Figure 3 is shown, arranged between the freezer compartment evaporator 20 and the suction pipe 30, so that the embodiment according to Figure 3 forms part of the invention.
  • the arrangement of the liquid separator 100 in the device is preferably vertical.
  • the liquid separator according to the invention makes it possible to prevent larger quantities of liquid refrigerant from remaining in the liquid separator when the compressor is idle. Rather, it is preferably arranged in such a way that the liquid refrigerant at least partially runs back into the evaporator when the compressor is idle and evaporates there and thus contributes to the cooling capacity of the device.
  • the liquid separator is designed and arranged in such a way that it prevents the liquid refrigerant from entering the suction line 300 which is connected downstream of the liquid separator 100. This means that the suction line no longer forms frost.
  • a preferred application of the present invention is the use of the liquid separator in a refrigerant circuit according to FIG Figure 3 , which in this respect also forms part of the present invention with the liquid separator.
