Definitions
- the invention relates to a cooling system with a refrigerant circuit having a plurality of evaporator sections and a distribution of refrigerant on the evaporator sections causing distribution, which has a controllable valve for each evaporator section.
- Such a cooling system is known from DE 195 47 744 A1.
- the known cooling system has a single compressor and a single condenser, but two separately formed evaporator.
- the refrigerant flow delivered by the compressor is split into two partial flows downstream of the condenser and upstream of the expansion valves using a 3/2-way valve, with the position of the 3/2-way valve being controlled by a control unit.
- This training however, only a division of the refrigerant flow to two evaporation sections is possible.
- a cooling system In order to be able to supply a plurality of evaporation sections, a cooling system is known from US Pat. No. 5,832,744, in which the distributor has a valve between a refrigerant inlet and a plurality of refrigerant outlets, to which a rotating turbine disk is connected downstream.
- the turbine disk should ensure that the refrigerant is evenly distributed to all outlets of the distributor and thus evenly to all evaporators.
- the over-supply or undersupply of the evaporator can lead to difficulties especially if temperature sensors, which are arranged at the evaporators or other locations of the cooling system, control an expansion valve.
- the expansion valve can be vibrated under unfavorable circumstances, which further deteriorates the capacity and the effectiveness of the cooling system.
- the invention has for its object to achieve a desired operation of the cooling system with simple means.
- the distributor has a housing and a rotor rotatably mounted in the housing, the periphery of which has at least one radially directed projection, which cooperates with a respective valve element of a valve.
- cooling system includes, in particular, cooling systems, freezer systems, air conditioning systems and heat pumps.
- the term "refrigeration plant” has been used for convenience only.
- the evaporator sections can be arranged in different evaporators. The invention will be explained for the sake of simplicity in the context of multiple evaporators. However, the invention is also applicable when a has steamer several individually or in groups controllable evaporator sections.
- the distributor thus has, for each evaporator section, a controllable valve that can be controlled by the radially directed projection of the rotor.
- This makes it possible to control the individual evaporator sections individually, i. It is possible to supply each evaporator with the amount of refrigerant it needs. There is no need to worry about the evaporators all having the same flow resistance. It is also of minor importance if the evaporators have to deliver different cooling capacity. An evaporator, which requires a larger cooling capacity, gets correspondingly more refrigerant than an evaporator, which has to provide little cooling capacity.
- valve of the evaporator which needs more refrigerant, remains open for a longer time with one revolution of the rotor than with an evaporator that requires less refrigerant. Since the rotor has a radially directed projection, it is sufficient if the rotor is sufficiently supported in the radial direction. All other bearings can then be relatively easily formed, because the forces acting here are small. A radially directed projection can also be relatively easily finished, for example in the form of a cam. You can supply more than two evaporator sections with little effort.
- valve elements are radially movable relative to the axis of rotation of the rotor.
- the effect of the radially directed projection can be converted directly into a movement of the valve element. This simplifies the construction of the distributor.
- each valve member has a return spring urging the valve member toward a valve seat. The valve thus remains closed without the action of the cam or radial projection on the rotor. Only when the projection acts on the valve element, it is lifted against the force of the return spring from the valve seat and thus opens the valve.
- the return spring is supported in a cage insert, which is arranged in an outlet opening of the housing.
- the cage insert is on the one hand able to support the return spring so that it can exert the necessary closing force on the valve element.
- the cage insert also has one or more passage openings of sufficient size so that refrigerant flowing through a gap between the valve element and the valve seat can also flow through the cage insert into the corresponding outlet of the distributor.
- the cage insert has a guide opening for the valve element, in which a shaft of the valve element is guided.
- the cage insert thus not only supports the return spring, but also guides the valve element linearly, so that the valve element can not tip over the valve seat or only to a permissible degree. This ensures that the valve can close tightly.
- the cage insert is press-fitted in the outlet opening.
- the pre-assembled cage insert with return spring and valve element is simply pressed into the outlet opening of the housing.
- the resulting frictional forces are sufficient to hold the cage insert in the housing.
- the forces acting on the cage insert forces are already relatively low anyway. They sit together with the valve element open by the force of Return spring and the pressure exerted by the refrigerant on the valve element.
- a plunger is arranged between the rotor and each valve element.
- the plunger forms a transmission element between the rotor and the valve element. This makes it possible to actuate valves in a relatively small rotor when they are arranged on a larger radius. This creates the opportunity to accommodate a sufficient number of valves. In addition, one has greater constructive freedom.
- the plunger has a length which is shorter than a distance between a valve element which bears against the valve seat, and the rotor outside the projection.
- a distance between a valve element which bears against the valve seat, and the rotor outside the projection When the valve is closed so there is a game between the plunger and the rotor. This can ensure that the valve remains closed in any case, when the plunger is not acted upon by the radial projection on the rotor.
- the clearance can be sized to ensure that the valves close securely over the entire temperature range for which the manifold is approved.
- the housing has a circumferential projection through which the plungers pass.
- the projection can also be interrupted in the circumferential direction, as long as it is ensured that there is a bore or a passage for each valve, through which the plunger is guided.
- the plungers are held in a plunger retaining ring.
- the plunger retaining ring is inserted into the housing. If, together with the umpteenth current projection is used, then it is ensured that the plunger are supported at two spaced in the direction of movement points. This makes it possible in the long run to ensure that the plungers and the valve elements always maintain a predetermined orientation relative to one another.
- the plungers preferably have a diameter reduction at their end facing the respective valve element.
- the plunger can thus be provided over the greater part of its length with a sufficiently large diameter, so that it can absorb the pressure forces which are transmitted from the projection of the rotor to the respective valve element. If he has a taper at its tip, then he is able to pass far enough through the opening, on the outside of the valve seat is formed. Thus, it is possible to open the valves sufficiently far, so that the flow resistance for the refrigerant can be kept small.
- each valve element is cone-shaped. This makes it easy to achieve a seal between the valve seat and valve element.
- the valve element can also be guided a little way through the opening, on the outside of the valve seat is formed so that it can be easily reached by the plunger.
- FIG. 1 is a schematic representation of a cooling system with multiple evaporators
- 3 shows the distributor in plan view without motor
- 4 is an enlarged view of the rotor with a projection
- Fig. 6 is an enlarged detail of Fig. 5 and
- Fig. 7 is a perspective view of a valve element in a cage insert.
- Fig. 1 shows a schematic representation of a cooling system 1, in which a compressor 2, a condenser 3, a collector 4, a manifold 5 and an evaporator assembly 6 with a plurality of evaporators arranged in parallel 7a - 7d are interconnected in a circuit.
- the Verdampferan- order 6 may also have a single evaporator having a plurality of evaporator sections, which are to be controlled individually or in groups. It is also possible to provide the evaporator assembly 6 with a plurality of evaporators, at least one of which has a plurality of evaporator sections.
- liquid refrigerant evaporates in the evaporators 7 a - 7 d, is compressed by the compressor 2, liquefied in the condenser 3 and collected in the collector 4.
- the distributor 5 is intended to distribute the liquid refrigerant to the individual evaporators 7a-7d.
- a temperature sensor 8a - 8d is arranged at the output of each evaporator 7a - 7d.
- the temperature sensor 8a-8d detects the temperature of the refrigerant leaving the evaporator 7a-7d.
- This temperature information is forwarded to a control unit 9, which controls the distributor 5 as a function of the temperature signals of the temperature sensors 8a-8d.
- FIGS. 2 to 7 now show the distributor 5 in a partially schematized representation.
- the distributor 5 has a drive motor 10, which is designed, for example, as a stepper motor.
- the drive motor 10 is mounted on a housing 11 having a non-visible in Fig. 2 input and a plurality of outputs 12.
- the control unit 9 may be integrated. However, it is also possible to arrange the control unit 9 separately from the engine 10 and to supply the engine 10 only with signals from the control unit 9.
- Fig. 3 shows the distributor 5 from above, with the motor 10 removed, so that one can see inside the distributor.
- the motor 10 serves, as can be seen in Fig. 2, at the same time as a cover for the housing. Between the motor 10 and the housing 11, a seal 13 is arranged, which prevents refrigerant from the housing 11 can escape.
- the motor 10 drives a rotor 14, which is arranged in the housing 11.
- the rotor 14 has a radial projection 15, which has the shape of a cam with two bevelled edges 16, 17.
- the projection 15 acts in each case on a plunger 18 and deflects this radially outward.
- the plungers 18 are held in a plunger retaining ring 19.
- the housing 11 has a projection 20 which projects into a distribution chamber 21.
- the plungers 18 are held in the projection 20 a second time.
- the distribution chamber 21 connects the input to the valves 22, one of which is provided for each output 12. In a projection 15 on the rotor 14 so one of the six valves 22 may be open. The opening time determines the amount of refrigerant that can flow through the corresponding valve and thus the corresponding output 12.
- the valves 22 are constructed equal to each other. Each valve 22 has a valve element 23 which cooperates with a valve seat 24. The valve element 23 has a cone-shaped head 25 which is guided through a housing wall 26, on the radial outer side of the valve seat 24 is arranged.
- the valve element 23 is pressed with its head 25 by the force of a return spring 27 in the direction of the valve seat 24.
- the return spring 27 engages the radially outer side of the head 25.
- a shaft 28 of the valve member 23 extends radially outward.
- the shaft 28 has a smaller diameter than the head 25, so that the return spring 27 has a sufficient contact surface.
- the return spring 27 is supported at its other end to a cage insert 29 which is pressed into an outlet opening 30.
- the cage insert 29 thus sits with a press fit in the housing 11.
- the cage insert 29 has a plurality of legs 31, with which it is held in the housing 11. In between there are intermediate spaces through which the refrigerant can flow into the corresponding outlet 12 when the valve 22 is open, that is to say from the valve seat 24, and lifted off from the valve seat 24.
- the cage insert 29 has a guide opening 34 and guides the shaft 28 of the valve element 23 so that the valve element 23 is sufficiently secured against tilting. This avoids tilting of the valve element 23 relative to the valve seat 24, provided that it goes beyond a predetermined extent.
- the plungers 18 are shorter than a distance between the valve element
- the plunger 18 has a diameter reduction 32 at its end, which cooperates with the valve element 23. This makes it possible, on the one hand, to ensure that the plunger 18 has a sufficient cross section in order to be able to absorb the pressure forces exerted by the projection 15 without deformation. On the other hand, in the region in which it cooperates with the valve element 23, it is thin enough to fit through the opening 33 in the wall 26 of the housing, on the radial outer side of which the valve seat 24 is arranged. It is therefore possible to ensure that even when the plunger 18 projects with its diameter reduction 32 into the opening 33, a sufficient flow cross section for the refrigerant through the corresponding valve 22 is given.
