The heating bypass assembly 20 is configured to be switchable between an on state and an off state, in which the heating bypass assembly 20 is activated to enable the refrigerant to flow from the inlet end to the outlet end of the heating bypass assembly 20. The inlet of the heating bypass assembly 20 is connected in parallel with the inlet of the condenser 13, the outlet of the heating bypass assembly 20 is connected in parallel with the inlet of the evaporator 14, and the ice making mold 40 is connected to the evaporator 14.
When the vehicle-mounted ice maker works in a heating cycle process, the heating bypass assembly 20 is in a conducting state, the first valve assembly 15 is in a blocking state, the compressor 12 is started, and the refrigerant directly flows to the evaporator 14 through the heating bypass assembly 20 to be heated and then returns to the compressor 12 through the throttling assembly 30. Therefore, in the heating cycle process, the refrigerant can only flow back to the compressor 12 from the throttling assembly 30, the flow of the refrigerant can be reduced by arranging the throttling assembly 30, the flow speed of the refrigerant flowing back to the compressor 12 is reduced, the working power of the compressor 12 can be reduced, the power consumption is reduced, and the operation cost is reduced.
Wherein the first valve assembly 15 comprises a first inlet connected to the evaporator 14 and the throttle assembly 30 comprises a second inlet connected to the evaporator 14, i.e. the first inlet and the second inlet are connected in parallel to the outlet of the evaporator 14. During cooling, the first valve assembly 15 is turned on, and a part of the refrigerant flows back to the compressor 12 through the first valve assembly 15, and another part flows back to the compressor 12 through the throttling assembly 30.
Specifically, a flow divider 51 is connected to the outlet of the evaporator 14, and the first inlet and the second inlet are both connected to the flow divider 51, so that the first inlet and the second inlet can be both connected to the evaporator 14. When cooling, the flow dividing member 51 divides the refrigerant flowing from the evaporator 14 to flow to the first valve assembly 15 and the throttling assembly 30, respectively. The flow divider 51 may be configured as a tee fitting or the like.
The piping assembly includes a first circulation pipe 111, a second circulation pipe 112, a third circulation pipe 113, and a fourth circulation pipe 114, the first circulation pipe 111 being disposed between the outlet end of the compressor 12 and the inlet end of the condenser 13, the second circulation pipe 112 being disposed between the outlet end of the condenser 13 and the inlet end of the evaporator 14, the filter-drier 16 and the first capillary tube 17 being connected in series to the second circulation pipe 112, the third circulation pipe 113 being disposed between the outlet end of the evaporator 14 and the inlet end of the first valve assembly 15, and the fourth circulation pipe 114 being disposed between the outlet end of the first valve assembly 15 and the inlet end of the compressor 12.
The heating bypass assembly 20 includes a first pipe 21 and a second valve assembly 22, an inlet of the first pipe 21 is connected in parallel with an inlet of the condenser 13, an outlet of the first pipe 21 is connected in parallel with an inlet of the evaporator 14, and the second valve assembly 22 is disposed on the first pipe 21. Wherein first valve component 15 is configured as a normally open solenoid valve and second valve component 22 is configured as a normally closed solenoid valve.
Specifically, the inlet end of the first pipe 21 may be connected to the first circulation pipe 111 or the outlet end of the compressor 12 or the inlet end of the condenser 13. The evaporator 14 may have two inlet ends connected to the second circulation pipe 112 and the outlet end of the first pipe 21, respectively; or the evaporator 14 has an inlet end to which the second circulation pipe 112 and the outlet end of the first pipe 21 are connected by a confluence structure such as a three-way joint; or the evaporator 14 has an inlet end and the outlet end of the first pipe 21 is connected to the second circulation pipe 112 between the evaporator 14 and the first capillary tube 17.
The throttle assembly 30 includes a second pipe 31 and a throttle member 32, the throttle member 32 is disposed on the second pipe 31, and an inlet of the second pipe 31 is the aforementioned second inlet. The third circulation pipe 113 is divided into two pipe sections, one of which connects the evaporator 14 and the branching member 51, i.e., the outlet of the evaporator 14 is connected to the branching member 51 through the pipe section, and the other of which connects the branching member 51 and the first valve assembly 15. Thus, the inlet end of the second pipe 31 is connected to the third circulation pipe 113 through the aforementioned branching piece 51, the outlet end of the second pipe 31 is connected to the fourth circulation pipe 114 through the merging piece 52, and the outlet of the second pipe 31 and the outlet of the first valve assembly 15 are connected in parallel to the fourth circulation pipe 114 through the merging piece 52. During cooling, the refrigerant flowing out of the evaporator 14 is branched by the branch member 51 to the first valve assembly 51 and the throttle member 32, and then the two flowing refrigerants are collected in the fourth circulation pipe 114 by the merging member 52. The confluence member 52 may be a tee pipe or the like.
In this embodiment, when the vehicle ice maker operates in the refrigeration cycle mode, the heating bypass assembly 20 is in the blocked state, the first valve assembly 15 is in the conducting state, the compressor 12 is started, the refrigerant flows to the condenser 13 through the first circulation pipe 111 to be condensed, and then is transmitted to the evaporator 14 through the drying filter 16 and the first capillary tube 17 on the second circulation pipe 112 to make ice, and then returns to the compressor 12 through the first valve assembly 15 and the throttle 32. Wherein the refrigerant may be slowed down by the first capillary tube 17, slowing down the flow of the refrigerant.
As described above, when the ice maker for vehicles is operated in the refrigeration cycle mode, the refrigerant flows back to the compressor 12 through the throttle member 32 and the first valve assembly 15 at the same time. When cooling is performed, most of the refrigerant is required to flow back through the first valve assembly 15, and therefore, the ratio of the flow area of the orifice 32 to the flow area of the first valve assembly 15 is set to 1: 20 to 1: 40. for example, for the narrowest point in the bore of the orifice 32 through which refrigerant passes at the first flow rate, the volume of refrigerant passing through the narrowest point per unit time is V1; when the second valve component 22 is open, the refrigerant passing through the narrowest point of the inner cavity of the second valve component 22 at the first flow rate is V2, and the ratio of V1 to V2 is 1: 20 to 1: 40.
the ratio of the flow area of the throttling element 32 to the flow area of the first valve assembly 15 can be set to 1: 20. 1: 25. 1: 30. 1: 36 and 1: 40, etc.
Further, during the refrigeration cycle, in order to make the flow of the refrigerant flowing out of the evaporator 14 stable and reduce the impact on the pipe assembly, the sum of the flow area of the orifice 32 and the flow area of the first valve assembly 15 may be set equal to the flow area of the third circulation pipe 113. Therefore, the thickness requirement of the pipeline assembly can be reduced, the material is saved to a certain extent, and the cost is saved.
In the present embodiment, the orifice 32 is provided as a second capillary tube.
In some embodiments, the restriction element 32 may be configured as a third valve assembly, specifically an electromagnetic on-off valve or a throttle valve, wherein the opening degree of the third valve assembly is smaller than the opening degree of the second valve assembly 22, i.e. the flow area of the third valve assembly is smaller than the flow area of the first valve assembly 15.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the gist of the present invention.
