Definitions

  • the present invention relates to a single-circuit refrigeration device with two independently temperature-controlled storage chambers.
  • a compressor, a condenser and the evaporator of typically two storage chambers in a refrigerant circuit are connected in series, so that the entire flow of the refrigerant circulated by the compressor successively flows through both evaporators.
  • the distribution of the available cooling capacity to the evaporator of the storage chambers is fixed in such a single-circuit refrigeration unit conventionally fixed by the geometry and arrangement of the evaporator.
  • the proportion of each storage chamber in the total refrigeration demand of the device varies depending on the ambient temperature.
  • the refrigeration demand of the warmer storage chamber decreases more than that of the colder storage compartment, so that when the operation of the compressor is controlled by the refrigeration demand of the warmer storage compartment is, the colder storage chamber is no longer sufficiently cooled. If, on the other hand, the compressor operation were controlled on the basis of the refrigeration requirement of the colder storage chamber, overcooling of the warmer storage chamber would result.
  • a known solution to this problem is to provide the warmer storage chamber a heater that can be switched on when operating in a cold environment to artificially increase the cooling requirements of the warmer storage chamber and so ensure a compressor running time sufficient to the colder storage chamber on a To maintain target temperature. It is obvious that such a heater severely affects the energy efficiency of the refrigerator.
  • Two-circuit refrigerators allow temperature control of two storage chambers of a refrigeration device independently.
  • the refrigerant line comprises two branches, with one of these branches, only one of the two evaporators can be acted upon with refrigerant and the other branch either the other or both evaporators are supplied in series with refrigerant.
  • the necessary branching makes the refrigerant circuit much more complicated and leads to higher manufacturing costs than a single-circuit refrigeration unit.
  • the object of the invention is therefore to provide a single-circuit refrigeration device that allows temperature control of two storage chambers independently, without having to heat one of the storage chambers.
  • the object is achieved by providing a condenser, a first throttle point, a first evaporator for cooling a first storage chamber formed in the housing in a single-circuit refrigeration device with a heat-insulating housing and a refrigerant circuit, between a pressure port and a suction port of a compressor, a second throttle point and a second storage chamber in the second housing cooling second evaporator are connected in series, the second throttle point has an adjustable Strömungsleitwert.
  • the adjustability of the Strömungsleitwerts makes it possible during the operation of the compressor different pressures in the two evaporators and thus different evaporation temperatures of the refrigerant in the two evaporators, depending on the desired temperature in the respective storage chamber set.
  • This solution is particularly applicable to Coldwall devices and therefore allows the production of highly energy-efficient, yet inexpensive refrigerators.
  • a control circuit may be connected and arranged with a first temperature sensor arranged on the first bearing chamber and with the second throttle point, the flow conductance of the second throttle point in the case of cooling demand in the first bearing chamber Up enforce.
  • control circuit can be connected to a arranged on the second bearing chamber second temperature sensor and be adapted to reduce the Strömungsleitwert the second throttle point at refrigeration demand in the second storage chamber. This results in a pressure and thus a temperature increase at the first evaporator, so that it receives less heat from the first storage chamber and a larger proportion of the available cooling capacity for cooling the second storage chamber is available.
  • control circuit When refrigeration demand occurs in both storage chambers, the control circuit should be able to provide more cooling capacity by increasing the speed of the variable speed compressor.
  • the Strömungsleitwert the second throttle body may be large in a state of maximum opening compared to the Strömungsleitwert the first throttle point.
  • the pressure built up by the compressor substantially completely drops at the first orifice, and the pressure difference between the two evaporators is small, so that substantially equal temperatures can be obtained in both of the storage chambers ,
  • the second storage chamber is expediently designed for a lower operating temperature than the first storage chamber.
  • at least the second storage chamber should be operable as a freezer. Whether the first storage chamber can also be used as a freezer compartment or at a higher temperature can be determined by setting the second throttle point.
  • at least the first storage chamber should be operable as a normal refrigeration compartment, which does not exclude the use at lower temperatures, with appropriate setting of the second throttle point.
  • the second orifice should include a continuous valve. Since different passage cross sections can be set constant on such a valve, pressure fluctuations of the refrigerant during compressor operation are minimized, which makes it possible to keep the noise emission of the refrigeration device as a whole low.
  • FIG. 1 shows a schematic representation of the refrigerant circuit of a refrigeration device according to the invention.
  • Fig. 2 is a schematic section through the housing of the refrigerator.
  • the refrigerant circuit shown in Fig. 1 comprises a speed-controlled compressor 1 with a pressure port 2 and a suction port 3.
  • a starting from the pressure port 2 refrigerant pipe 4 extends in the direction of circulation of the refrigerant first via a condenser 5 and a first throttle point 6, here in the usual way
  • a second, adjustable throttling point 8 is located between an outlet port of the evaporator 7 and an inlet port of a second evaporator 9.
  • An outlet port of the evaporator 9 is connected to the suction port 3 of the compressor 1.
  • Two temperature sensors 10, 11 are arranged in storage chambers 12, 13 cooled by the evaporators 7 and 9, respectively, and connected to a control unit 14 which uses the temperatures detected by the temperature sensors 10, 11 to determine the speed of the compressor 1 and the flow rate of the throttle point 8 controls.
  • the control unit 14 continuously compares the temperatures detected by the temperature sensors 10, 11 with conventionally user settable setpoint temperatures for the storage chambers 12, 13.
  • the control unit determines 14 refrigeration demand of the respective storage chamber; This determination remains until the temperature measured in the chamber in question has fallen by more than ⁇ below the setpoint temperature of the relevant compartment.
  • the increment may be fixed or determined by the control unit 14 in proportion to the deviation of the measured temperature from the desired temperature of the respective storage chamber. If a few minutes after the adjustment of the throttle point 8 a temperature decrease is detected, the adjustment of the throttle point 8 is obviously sufficient; If no temperature decrease is detected, then the Strömungsleitwert is again incremented.
  • control unit 14 determines refrigeration demand in the storage chamber 13. This finding also remains until the temperature in the storage chamber 13 drops by at least ⁇ below the setpoint.
  • the control unit 14 reacts by reducing the flow conductance of the throttle point 8. As a result, the pressure in the evaporator 7 increases, and the pressure in the evaporator 9 drops. As a result, the evaporation temperature in the evaporator 7 increases, and less heat is taken up from the storage chamber 12, so that a larger proportion of the refrigerant in the liquid state reaches the evaporator 9. Thus, at the expense of Cooling of the storage chamber 12, more cooling capacity for cooling the storage chamber 13 available.
  • the speed of the compressor 1 as a whole is sufficient to keep both chambers 12, 13 at their desired temperatures, phases of enhanced cooling of the chamber 12 and phases of enhanced cooling of the chamber 13 thus alternate. If longer periods exist in which neither the chamber 12 nor the chamber 13 has refrigeration demand, the power of the compressor 1 is higher than for cooling the chambers 12, 13 required; In this case, the speed of the compressor 1 is slowly and in small increments decremented to find a set value at which the performance of the compressor 1 corresponds to the refrigeration demand of the chambers 12, 13 as closely as possible.
  • Simultaneous refrigeration demand in both chambers 12, 13 is an indication that the performance of the compressor 1 is not sufficient to keep the chambers 12, 13 at the set temperature; therefore, in such a case, the control unit 14 slowly and stepwise increments the speed of the compressor 1 until there is no refrigeration demand in one of the storage chambers 12, 13.
  • the above-described hysteresis in determining the existence or non-existence of refrigeration demand causes the storage chambers 12, 13 tend to have each out of phase refrigeration demand.
  • the compressor 1 can therefore very evenly, rarely and only by a few steps changed speed work; Due to the continuous operation, the temperatures of both evaporators 7, 9 can be kept close to the target temperature of the respective storage chamber 12 and 13, respectively, which results in a distribution of the cooling capacity to the storage chambers 12, 13 very energy efficient operation allowed.
  • the throttle point 8 is formed by a continuous valve, the passage cross-section can take many of the respective to be realized Strömungsleit staple corresponding positions stationary, pressure fluctuations in the refrigerant circuit are avoided, which could lead to the emission of operating noise.
  • FIG. 2 shows a schematic section through a refrigeration device with the refrigerant circuit shown in FIG. 1.
  • His case 15 includes in a usual way a heat-insulating body 16, in which the two bearing chambers 12, 13, each closed by a door 17, are formed.
  • the evaporators 7, 10 are each arranged between an inner container 20 of the bearing chambers 12, 13 and an insulating material layer 18 surrounding them. They may, in the case of the storage chamber 12, be arranged only on a rear wall 19 or, as in the case of the storage chamber 13, extend to other walls of the inner container 20.
  • the compressor 1 and, in the case considered here, the condenser 5 and the second throttle point 8 are housed in a machine room 21 at the back of the body 15.
  • the evaporator 7 located upstream in the refrigerant circuit is here also the evaporator of the upper storage chamber 12, so that the direction of circulation of the liquid refrigerant through the evaporators 7, 9 is substantially from top to bottom. Since the pressure in the upstream evaporator 7 can never be lower than in the downstream evaporator 9, the storage chamber 12 can be used as a normal refrigerating compartment and the storage chamber 13 as a freezer, but not vice versa.
  • a second operating mode can be set on the control unit 14, in which the throttle point 8 is always held in a state of maximum passage cross section, so that the pressure difference between the two evaporators 7, 9 is negligible compared to that at the throttle point 6.
  • this operating state depending on the setting of the power of the compressor 1, both storage chambers 12, 13 with the same desired temperature, in particular as a normal refrigeration compartment or as a freezer, operable.
