Definitions
- the invention relates to a device and a method for controlling a fluid level of a working fluid of a heat pump.
- working fluids In refrigeration machines, in particular in heat pumps, fluids are typically used as working fluid (working fluids).
- working fluid circulates within a working cycle of the heat pump.
- the working fluid is introduced during the initial commissioning of the heat pump in the working cycle of the heat pump and thus filled the heat pump.
- the working cycle of the working fluid is closed during operation of the heat pump.
- the working fluid of the heat pump circulates within a closed working cycle.
- no influence can be exerted on the working cycle of the working fluid, in particular on a temperature profile of the working fluid.
- heat pumps deliver the heat absorbed by a heat source to a heat sink.
- fluctuations in the temperature of the heat sink and the temperature of the heat source can occur.
- Known heat pumps can only react insufficiently to temperature fluctuations of the heat sink and / or the heat source.
- the present invention is therefore an object of the invention to allow adaptation of a heat pump to temperature fluctuations of a heat sink.
- the object is achieved by a device having the features of independent claim 1 and by a method having the features of independent claim 9.
- advantageous refinements and developments of the invention are given.
- the device comprises a storage container and a heat pump, which heat pump comprises at least one condenser, an expansion valve, an evaporator and a compressor, wherein the heat pump comprises a circulating working fluid working circuit, the reservoir being connected between the condenser and the working circuit with respect to the working circuit Evaporator is arranged and the reservoir for controlling a fluid level of the working fluid in the condenser comprises a piston and / or a membrane.
- the fluid level of the working fluid in the condenser of the heat pump can be advantageously controlled.
- the control of the fluid level of the working fluid in the condenser of the heat pump by the piston for example by a
- a control of the fluid level during operation of the heat pump is made possible by the device according to the invention.
- a height or a level of the fluid column (liquid column) of the working fluid in the condenser can be used as a measure of the fluid level.
- condensed water accumulates during operation of the heat pump. Beitsfluid at the bottom of the capacitor, wherein the condensed working fluid in the condenser is supercooled by the thermal contact with a heat sink.
- the fluid level is in this case given by the height of the liquid column of the working fluid accumulated in the capacitor.
- Fluid level the supercooling of the working fluid are regulated. According to the invention can be reacted by controlling the subcooling of the working fluid in the condenser on temperature fluctuations of the heat sink.
- the supercooling of the working fluid in the condenser can be adapted to the temperature fluctuations of the heat sink, wherein the adaptation takes place in such a way that the heat pump always works as efficiently as possible.
- heat pumps which are known from the prior art have non-controllable subcooling of the working fluid, since the fluid level in the condenser is approximately constant. An adaptation to the temperature fluctuations of the heat sink is therefore not according to the prior art.
- the fluid level by controlling the fluid level, it is possible to react directly to fluctuations in the heat sink and / or a heat source by regulating the subcooling of the working fluid.
- increased subcooling of the working fluid may be advantageous, since the enthalpy difference in the condenser is increased by the increased subcooling of the working fluid.
- this increases the coefficient of performance (COP) and consequently the efficiency of the heat pump.
- Another advantage of the invention is that large temperature fluctuations of the heat source and / or the heat sink mit- A small change in the fluid amount of the working fluid can be regulated. This can be dispensed with an oversized Fluid Pavllmenge of the working fluid within the working cycle of the heat pump.
- overheating of a suction gas via the subcooling of the working fluid can advantageously be regulated during operation with recuperators.
- the fluid level of the working fluid in the condenser of the heat pump is regulated by means of a piston and / or a diaphragm, whereby a regulation of the subcooling of the working fluid takes place and consequently the efficiency of the heat pump is improved with temperature fluctuations of the heat sink.
- a working fluid circulating within a working cycle of the heat pump is condensed by means of a condenser, expanded by means of an expansion valve, evaporated by means of an evaporator and compressed by means of a compressor, the working fluid being connected between the condenser and the working circuit with respect to the working circuit Evaporator is passed to a reservoir, wherein a fluid level of the working fluid in the condenser is controlled by means of a piston and / or a membrane of the reservoir.
- the fluid level of the working fluid in the heat pump can be regulated by means of a translatory movement of the piston and / or a displacement and / or a deformation of the diaphragm.
- the storage container which comprises a piston, is fluidically coupled to the heat pump via an outlet and inlet valve, the outlet valve being connected with respect to the working cycle. fes between the condenser and the expansion valve and the inlet valve between the expansion valve and the evaporator is arranged.
- working fluid is thus conducted to the reservoir after the condenser and before the expansion valve. This is advantageous because the working fluid after the condenser and before the expansion valve has a high pressure. It is thus possible to remove large amounts of working fluid from the heat pump working circuit for a short period of time and to feed it to the storage container.
- the working fluid of the heat pump is temporarily stored in the liquid state of matter.
- the introduction of the working fluid in the reservoir is preferably carried out with open exhaust valve and closed inlet valve.
- the regulation of the fluid level is effected by an enlargement and / or reduction of the storage volume (volume which is the working fluid in the reservoir available) by means of a linear displacement of the piston.
- a storage container which is designed as a hydraulic cylinder.
- the reservoir can be realized technically in a simple manner by a hydraulic cylinder, preferably by a double-acting hydraulic cylinder.
- a pressure within the hydraulic cylinder of at most 20 MPa is preferred.
- valves each comprise a further expansion valve and a check valve.
- this pressure differences between the working cycle of the heat pump and the reservoir can be compensated.
- the reservoir is designed as a collector, wherein the collector comprises a membrane and the collector is arranged with respect to the working cycle between the condenser and the expansion valve.
- the collector is thereby integrated directly into the working cycle of the heat pump.
- This collects the Working fluid of the heat pump in the collector, wherein the fluid quantity of the accumulated in the collector working fluid can be changed by means of the membrane.
- deformation of the membrane enlarges or reduces a first partial volume of the collector which is limited by the membrane, as a result of which a second partial volume (collecting volume) which is available to the working fluid within the collector is reduced or enlarged. If the subcooling of the working fluid in the condenser is to be increased, then the first partial volume within the collector is increased and consequently the second partial volume is reduced.
- the first partial volume in the collector is reduced by the membrane, so that more liquid working fluid collects in the second partial volume of the collector.
- the second partial volume (collecting volume) which is available to the working fluid in the collector, by means of the membrane, the fluid level of the working fluid in the condenser is thus changed.
- the deformation of the membrane and the resulting change in the first or second partial volume of the collector is advantageously controlled by means of the introduction of compressed air into the first partial volume bounded by the membrane.
- the first partial volume of the collector is increased upon introduction of compressed air, so that the second partial volume, which is the working fluid within the collector available, is reduced.
- a reduction of the first partial volume is advantageously carried out with a compressed air outlet valve which is coupled to the collector. If compressed air from the first partial volume of the collector is discharged via the compressed air outlet valve coupled to the collector, the first partial volume is reduced.
- the second partial volume increases, which is available to the working fluid in the collector.
- the collector comprises a displacement unit which is designed for mechanical displacement of the membrane.
- the first partial volume is increased or decreased.
- a regulation of the fluid level of the working fluid since correspondingly reduces or increases the second partial volume (collection volume).
- the outlet valve can be advantageously dispensed with in this embodiment.
- a control of the fluid level by means of the piston and / or the membrane of the working fluid take place, if a fluid standschwellwert the working fluid in the condenser is exceeded or fallen below.
- the fluid level of the working fluid in the condenser is positively correlated with the subcooling of the working fluid, advantageously takes place via the control of the fluid level a regulation of the subcooling of the working fluid. If a certain fluid level, which corresponds, for example, to the fluid level threshold, is exceeded, the working fluid may be overcooled too much. As a regulation, therefore, a reduction of the fluid level of the working fluid must take place. In the opposite case of falling below the Fluidstandschwellivess can be increased by a control of the fluid level of the working fluid in the condenser, so that sets the desired increased undercooling of the working fluid.
- a control of the fluid level of the working fluid if a temperature threshold value of the working fluid is exceeded or fallen below.
- the temperature of the working fluid in the condenser is typically indirectly proportional to the fluid level of the working fluid in the condenser. At a high fluid level, there is a large undercooling and thus a low temperature of the working fluid, while at a low fluid level there is a higher temperature and thus a lower subcooling of the working fluid.
- the measurement of the temperature of the working fluid is thus advantageously carried out within the condenser of the heat pump. Further measuring points of the temperature and / or the fluid level in the working cycle of the working fluid can be provided.
- Figure 1 shows a heat pump with a reservoir
- Hydraulic cylinder is formed; and Figure 2 shows a heat pump with a collector comprising a diaphragm for controlling the fluid level. Similar elements may be provided in the figures with the same reference numerals.
- FIG. 1 shows a device 1 which comprises a heat pump 4 and a reservoir 2, the heat pump 4 having a condenser 6, an expansion valve 8, an evaporator 10 and a compressor 12.
- the heat pump 4 is coupled via an outlet valve 18 and via an inlet valve 20 to the reservoir 2 fluidly via a working fluid 24 of the heat pump 4.
- the working fluid 24 circulates in the heat pump 4 in a working cycle 42.
- the reservoir 2 is designed as a hydraulic cylinder 2 and comprises a piston 14.
- a regulation of a supply volume 30 of the hydraulic cylinder 2 takes place here via a rectilinear movement of the piston 14, wherein the rectilinear movement in Figure 1 by the directional arrows 32, 33 is clarified.
- a first partial volume 30, which is available to the working fluid 24 in the hydraulic cylinder 2 is increased (directional arrow 33) or reduced (directional arrow 32) by means of the rectilinear movement of the piston 14.
- the working fluid 24 condensed in the condenser 6 is introduced into the hydraulic cylinder 2 with respect to the working circuit 42 or with respect to a direction of the working circuit 42 after the condenser 6 and before the expansion valve 8.
- the introduction of the working fluid 24 into the hydraulic cylinder 2 before the expansion valve 8 so that the working fluid 24 under high pressure, for example in the range of 10 MPa to 20 MPa, is introduced into the hydraulic cylinder 2. Due to the increased pressure can be removed from the working circuit 42 of the heat pump 4 and introduced into the hydraulic cylinder 2 large amounts of working fluid 24 in only a short time. In other words, the increased pressure increases the mass flow of the working fluid 24 in the outlet valve 18.
- further expansion valves 21 and check valves 22 are provided for the outlet and inlet valves 18, 20.
- the outlet valve 18 is closed and the inlet valve 20 is opened.
- the working fluid 24 by a rectilinear movement - indicated by the directional arrow 32 - pressed out of the hydraulic cylinder 2.
- the return of the working fluid 24 takes place relative to the working circuit 42 preferably after the expansion valve 8 at a low pressure level.
- the working fluid 24 can be brought directly to the evaporation. If now by an increase of the storage volume 30 by means of a movement of the piston 14 - indicated by the directional arrow 33 - more working fluid 24 collected in the hydraulic cylinder 2, the fluid level of the working fluid 24 in the condenser 6 decreases.
- the working fluid 24 thus leaves the condenser 6 approximately at the boiling line and is thus in thermodynamic equilibrium with its vapor phase. In other words, the working fluid 24 is not or only slightly supercooled.
- the illustrated device 1 makes it possible to regulate the fluid level of the working fluid 24 in the condenser 6 of the heat pump 4, so that the supercooling of the working fluid 24 in the condenser 6 can be regulated.
- FIG. 2 shows a device 1 comprising a heat pump 4 and a collector 3, wherein the heat pump 4 comprises a condenser 6, an expansion valve 8, an evaporator 10 and an evaporator 10. NEN compressor 12 has.
- the collector 3 comprises a membrane 16, which membrane 16 divides a total volume of the collector 3 into a first and second partial volume 30, 31.
- a working fluid 24 circulating in a working cycle 42 of the heat pump 4 is collected in the second partial volume 31 (collecting volume) of the collector 3.
- the collector 3 is arranged downstream of the condenser 6 and upstream of the expansion valve 8 and integrated directly into the working cycle 42 of the heat pump 4.
- the first partial volume 30, which is limited by the membrane 16, is increased by introducing compressed air by means of an air compressor 26.
- An enlargement or reduction of the sub-volume 30 translates into a reduction or enlargement of the second sub-volume 31.
- the second partial volume 31 is increased, so that more working fluid 24 accumulates in the collector 3.
- the fluid level of the working fluid 24 in the working cycle 42 of the heat pump 4 is reduced so that working fluid 24 is withdrawn from the condenser 6 and a reduction in the subcooling of the working fluid 24 in the condenser 6 takes place.
- working fluids 24 known prior art working fluids, such as R134a and / or R245fa can be used.
- the use of R134a, R400c and / or R410a may also be provided.
