Definitions

  • the invention relates to a process for injecting the refrigerant into a two-compartment refrigeration cabinet fitted with a single compressor to supply the evaporators in each compartment in series, and to a refrigeration cabinet implementing this method.
  • the commonly accepted standards stipulate that the temperature in the compartment used for freezing and storing food must not be higher than -18 ° C, and that the temperature in the compartment used for storage or refrigeration of fresh foodstuffs must be between 0 ° C and 5 ° C. These conditions must be fulfilled for an ambient temperature between 16 ° C and 32 ° C.
  • the difference between the atmosphere and the desired temperature in the freezer compartment is 50 ° C; the difference between the ambience and the desired temperature in the refrigeration compartment is 27 ° C.
  • the ratio r of the differences is therefore substantially equal to 2.
  • the difference between the atmosphere and the desired temperature of the freezer compartment is 34 ° C; the difference between the ambience and the desired temperature for the refrigeration compartment is 11 ° C.
  • the ratio R of the differences is therefore approximately equal to 3.
  • the losses do not depend on the ambient temperature.
  • the needs of each compartment are proportional to the temperature differences.
  • the ratio of the refrigeration requirements of the freezing compartment to the refrigeration requirements of the refrigeration compartment is therefore half the time at 16 ° C than at 32 ° C.
  • the regulating thermostat is generally located in the refrigeration compartment, which means that at 16 ° C ambient, the freezing compartment will only be partially satisfied in refrigeration needs and will reach for example a temperature of -15 °. vs.
  • the resistance is used in so-called normal injection mode: the refrigerant first passes through the evaporator of the refrigeration compartment, then into that of the freezing compartment.
  • the evaporator of the freezing compartment is first supplied, then that of the refrigeration compartment in which the regulation thermostat is placed.
  • the refrigerant by vaporizing inside an evaporator, absorbs calories in the associated compartment.
  • the vaporization is progressive and takes place as the fluid advances in the evaporation circuit.
  • the limit is located in the refrigeration compartment which is at the end of the circuit.
  • the evaporator in the refrigeration compartment is completely effective because the filling with refrigerant is carried out so that it is so, on the contrary at 16 ° C, this evaporator only becomes effective in part. There is a decline in the filling limit, which therefore varies according to the ambient temperature.
  • the freezer compartment evaporator is always fully efficient. The refrigeration needs of this compartment are therefore fully satisfied.
  • the purpose of the injection method of the invention is to remedy the various drawbacks caused by the methods of the prior art.
  • a method of injecting the refrigerant into the refrigeration circuit of a cabinet with two compartments at different temperatures, equipped with a single motor-compressor, in order to obtain fixed values of temperatures in the compartments, for room temperatures between a minimum and a maximum value is characterized in that the evaporator of the higher temperature compartment has two parts, and in that, the regulation being carried out in the higher temperature compartment, the fluid after compression and expansion circulates in series in a first part of the evaporator of the higher temperature compartment, then in the evaporator of the lower temperature compartment before circulating in a second part of the evaporator of the higher temperature compartment high and return to the compressor, and in that the refrigerant circuit is charged with refrigerant so that all of the evaporators rs is effective at maximum ambient temperature and in that the surfaces and / or the lengths of each part of the evaporator of the higher temperature compartment are optimized according to the refrigeration needs of the two compartments at extreme ambient temperatures .
  • the lower temperature compartment is a freezing compartment and the higher temperature compartment is a refrigeration compartment.
  • the respective proportions between the first and second parts of the evaporator of the compartment at higher temperature are calculated according to the refrigerating needs of each compartment at the extreme ambient temperatures in which must operate the refrigeration cabinet.
  • the refrigeration unit 1 comprises two compartments at different temperatures: a compartment II at a temperature of the order of -18 ° C., called the freezing and preservation compartment and a compartment 12 at one temperature of the order of + 5 ° C called the refrigeration compartment.
  • Figure 2 illustrates the refrigeration circuit and the power supply of the motor-compressor.
  • the temperatures in the compartments are maintained using a unique capillary type refrigeration circuit fitted with a single compressor.
  • the regulation is carried out using a thermostat T placed in the refrigeration compartment. This thermostat, when it opens, cuts off the electrical supply to compressor 20.
  • the electrical circuit is connected to the supply network by terminals El and E2.
  • the refrigeration circuit comprises, in series, a motor compressor 20, a condenser 21, a filter drier 22, a capillary 23.
  • a first part 121 of the evaporator of the refrigeration compartment At the outlet of the capillary 23 is a first part 121 of the evaporator of the refrigeration compartment. In series with this first part is the evaporator 111 of the compartment freezing. The outlet of the evaporator 111 from the freezing compartment is connected to the inlet of a second part 122 of the evaporator of the refrigeration compartment.
  • the outlet of the second part 122 of the evaporator of the refrigeration compartment is connected to a boiler 24, and the return of the fluid to the compressor 20 takes place in a pipe 25, at the outlet of the boiler.
  • this exchange of heat is carried out using a coaxial system, that is to say say that the capillary is placed inside the tubing.
  • the evaporator 121, 122 of the refrigeration compartment is produced using a panel 120 of Roll Bond.
  • the method of producing such an evaporator consists in welding laminated aluminum sheets in superposition. Special ink is deposited in places on the sheets to be welded: welding takes place outside the places where the ink has been deposited.
  • the evaporator parts 121, 122 are produced by injecting a high pressure liquid at the places where the sheets have not been welded.
  • the high pressure causes inflation between the two sheets.
  • the evaporator thus takes the form of a panel where the circulation circuits 121, 122 are reliefs.
  • the bouiJleur 24 is also produced on the panel 120 by the Roll Bond process.
  • the freezer compartment evaporator 111 is in the form of a flattened tube. Its length is about fifteen meters.
  • the evaporator 111 of the compartment can be produced by the Roll Bond technique.
  • this evaporator is in the form of a panel 110.
  • the evaporators are arranged vertically.
  • the separation between the two parts of the evaporator of the refrigeration compartment is then carried out in the height direction for reasons of convenience.
  • the first part 121 occupies a height H and the second part 122 occupies a height h.
  • each evaporator part is therefore proportional to the heights of these parts.
  • the height H of the first part 121 of the evaporator of the refrigeration compartment represents two thirds of the total height of the evaporator.
  • the second part 122 has a height h equal to the remaining third.
  • the respective surfaces of the evaporator parts are two thirds of the evaporator and one third of the evaporator.
  • the losses are independent of the ambient temperature, but the needs of each compartment depend on this ambient temperature and since the regulation takes place in the refrigeration compartment, it follows that a maximum temperature of - 18 ° C is obtained in the freezer compartment, in all ambient conditions, as soon as the temperature in the refrigeration compartment reaches 5 ° C and the evaporator of the freezer compartment is fully efficient.
  • the refrigeration circuit is loaded so that all of the evaporators are effective at 32 ° C ambient (that is to say, so that the filling limit is at the end of the refrigeration circuit) , and the total dimensions of the evaporators are chosen so that the desired temperatures in each compartment are reached at this environment.
  • the efficiency of an evaporator is proportional to the useful surface of this evaporator, that is to say to the surface of the pipes. However, this surface is proportional to the length of the pipes. So the efficiency depends indifferently on the useful surface or the useful length.
  • the ratio of the useful surface (or length) of the first part 121 of the evaporator of the refrigeration compartment to the total surface (or length) of this evaporator must therefore be equal to r
  • the second part 122 of the evaporator of the refrigeration compartment 12 is equivalent to at least one third of the total of the evaporator of this compartment, then all of the evaporators will be effective at 32 ° C and only the first part 121 of the evaporator in the refrigeration compartment and all, or almost all of the evaporator 111 in the refrigeration compartment freezing will be effective at 16 ° C.
  • the filling limit may vary and be slightly inside the freezing compartment, but this does not matter because the length of the evaporator in this compartment is very important compared to the dispersions which may be obtained.
  • the first part of the evaporator of the refrigeration compartment, the entire evaporator of the freezing compartment and a portion of the second part of the refrigeration compartment will be effective.
  • the injection method of the invention makes it possible to increase the performance of a refrigeration unit with two compartments, under these extreme conditions of use at a lower cost because it makes it possible to dispense with compensation resistors.
