Definitions

  • the present invention relates to the refrigeration field, and in particular, to a refrigeration system having a falling film evaporator.
  • an oil intake point corresponding to an oil return branch generally is also disposed at the lower portion inside the housing of the falling film evaporator, to suck refrigerant in which the lubricating oil is dissolved into the compressor for lubrication.
  • an oil intake point corresponding to an oil return branch generally is also disposed at the lower portion inside the housing of the falling film evaporator, to suck refrigerant in which the lubricating oil is dissolved into the compressor for lubrication.
  • an unduly high oil concentration in the refrigerant liquid is caused, increasing the flow resistance and affecting the oil return.
  • US 5561987 A discloses a compression refrigeration apparatus using a falling film evaporator and utilizing a vapor-liquid separator where refrigerant vapor is conveyed by a bypass line to the evaporator inlet located on the lower heat exchange surface below the nominal level of the pool so that vapor agitates the mixture of refrigerant and lubrication oil in the pool.
  • An objective of the present invention is to provide a refrigeration system and a falling film evaporator, to balance the thermodynamic property and the lubricating oil recovery effect of the refrigeration system having the falling film evaporator.
  • the present invention provides a refrigeration system as defined in claim 1. It comprises: a refrigeration loop having an air outlet of a compressor, a condenser, a throttle element, a falling film evaporator, and an air inlet of the compressor which are connected in sequence by pipes, wherein the falling film evaporator comprises a housing, a distributor located at an upper portion inside the housing, and a heat exchange pipeline located below the distributor; an oil return branch having an oil intake point connected to a lower portion of the falling film evaporator and an oil return point connected to the air inlet of the compressor; and characterized by a bypass branch having a bypass inlet disposed on the distributor and connected to downstream of the throttle element, and a bypass outlet connected to the lower portion of the falling film evaporator and used for introducing part of gas-liquid two-phase refrigerant into the falling film evaporator.
  • the refrigeration system comprises: a refrigeration loop 100 for realizing a main refrigeration function, an oil return branch 200 for providing a lubricating oil return to the compressor, and a bypass branch 300.
  • the refrigeration loop 100 has an air outlet 110b of a compressor 110, an oil separator 150, a condenser 120, a throttle element 130, a falling film evaporator 140, and an air inlet 110a of the compressor 110 which are connected in sequence by pipes.
  • the falling film evaporator 140 comprises a housing 141, a distributor 142 located at an upper portion inside the housing 141, and a heat exchange pipeline 143 located below the distributor 142.
  • refrigerant after being compressed by the compressor 110, flows from the air outlet 110b into the condenser 120 for condensation, and is then throttled by the throttle element 130.
  • the throttled two-phase refrigerant enters the falling film evaporator 140.
  • the gas phase refrigerant will be directly sucked into the compressor 110.
  • the liquid phase refrigerant is distributed by the distributor 142, forms a refrigerant liquid film to flow through the heat exchange pipeline 143 inside the falling film evaporator 140, and exchanges heat with a to-be-cooled medium therein. After the heat exchange, the gas phase refrigerant obtained by evaporation is sucked into the compressor 110, to participate in a new working cycle.
  • the oil return branch 200 has an oil intake point 210 connected to a lower portion of the falling film evaporator 140 and an oil return point 220 connected to the air inlet 110a of the compressor 110.
  • part of lubricating oil that provides lubrication for the compressor 110 will enter the refrigeration cycle along with the flow of the refrigerant.
  • this part of lubricating oil that enters the refrigeration cycle can be sucked from the lower portion of the falling film evaporator 140 back into the compressor 110. Therefore, impact on both the heat exchange effect of the refrigerant and the lubrication effect of the compressor can be avoided.
  • the bypass branch 300 has a bypass inlet 320 connected to downstream of the throttle element 130 and a bypass outlet 310 connected to the lower portion of the falling film evaporator 140.
  • the bypass inlet 320 is disposed on the distributor 142, and is used for introducing part of gas-liquid two-phase refrigerant into the falling film evaporator 140.
  • part of gas-liquid two-phase refrigerant downstream of the throttle element 130 will flow into the lower portion of the falling film evaporator 140 through the bypass branch 300, so that the refrigerant in the lower portion inside the housing 141 of the falling film evaporator reaches a preset liquid level.
  • the preset liquid level enables the liquid phase refrigerant to form a sufficiently large liquid level at the lower portion inside the housing 141 of the falling film evaporator, so that droplets of lubricating oil from above the falling film evaporator can substantially come into contact with the liquid level and be dissolved in the refrigerant.
  • Such a configuration makes it easier to suck most of the lubricating oil back to the compressor through the oil return branch, achieving an efficient oil return function.
  • the specific height value of the preset liquid level or the specific value of the area of the liquid level depends on various parameters such as a profile of the housing of the evaporator and a required oil return ratio. Under the teachings of the foregoing embodiment, a person skilled in the art can integrate the related parameters and set the liquid level in an actual application environment without creative efforts.
  • the bypass branch is improved from multiple aspects, which will be described one by one.
  • the bypass inlet 320 is higher than the bypass outlet 310 in a vertical direction.
  • the gravity of the refrigerant caused by the height difference between the two can also be used as a power source for driving the bypass refrigerant to flow.
  • an auxiliary driving apparatus may be additionally disposed on the bypass branch 300, to provide more power to suck the two-phase refrigerant from the bypass inlet 320 to the bypass outlet 310.
  • the bypass branch 300 has a plurality of bypass inlets 320 and/or a plurality of bypass outlets 310.
  • the bypass inlets 320 and the bypass outlets 310 may belong to a same bypass branch, i.e., similar to the configuration of a liquid collector or liquid separator; or may belong to different bypass branches.
  • the falling film evaporator comprises a plurality of bypass branches 300, and each of the bypass branches may comprise at least one bypass inlet and/or bypass outlet.
  • the plurality of bypass outlets 310 can also be arranged in an evenly spaced manner on the lower portion of the housing 141 of the falling film evaporator. Thereby, the bypass refrigerant can be fed to the evaporator more evenly, thereby avoiding undue impact.
  • the bypass outlet 310 may be arranged at the bottom of the housing 141 of the falling film evaporator.
  • the refrigerant that enters the evaporator through the bypass outlet 310 basically does not unduly affect the original refrigerant liquid level in the evaporator, making the entire bypass process more stable.
  • a smallest flow cross-sectional area of a pipe of the bypass branch 300 is 0.5%-20% of a flow cross-sectional area of a pipe of the refrigeration loop 100 downstream of the throttle element 130.
  • the amount of the bypass refrigerant can meet the requirement for increasing the liquid level, and will not cause great impact to the normal cycle.
  • an unduly large amount of refrigerant accumulated in the housing of the falling film evaporator is not desirable in the present invention, because this has only a limited effect in improving the heat exchange efficiency and greatly increases the charging amount of the refrigerant as well as material costs. Therefore, the foregoing problem can be well resolved by limiting the flow area of the bypass branch to control the bypass flux, and a balance between efficiency and costs can be achieved.
  • a pipe of the bypass branch 300 has a circular and/or rectangular and/or trough-type cross-section, to adapt to different application scenarios and flow conditions.
  • bypass inlet of the bypass branch may further be connected to the distributor, though not shown in the figure.
  • the bypass branch can be considered to be part of the falling film evaporator.
  • the falling film evaporator comprises: a housing; a distributor disposed at an upper portion inside the housing; a heat exchange pipeline disposed inside the housing and below the distributor; an oil intake point disposed at a lower portion of the falling film evaporator; and a bypass branch having a bypass inlet connected to the distributor and a bypass outlet connected to the lower portion of the falling film evaporator and used for introducing part of gas-liquid two-phase refrigerant into the lower portion of the falling film evaporator, so that the refrigerant in the lower portion inside the housing of the falling film evaporator reaches a preset liquid level.
  • the preset liquid level enables the liquid phase refrigerant to form a sufficiently large liquid level at the lower portion inside the housing of the falling film evaporator, so that droplets of lubricating oil from above the falling film evaporator can substantially come into contact with the liquid level and be dissolved in the refrigerant, thereby achieving an efficient oil return function.
  • the bypass branch is improved from multiple aspects, which will also be described one by one.
  • the bypass inlet is generally higher than the bypass outlet in a vertical direction.
  • the gravity of the refrigerant caused by the height difference between the two can also be used as a power source for driving the bypass refrigerant to flow.
  • an auxiliary driving apparatus may be additionally disposed on the bypass branch, to provide more power to suck the two-phase refrigerant from the bypass inlet to the bypass outlet.
  • the bypass branch has a plurality of bypass inlets and/or a plurality of bypass outlets.
  • the bypass inlets and the bypass outlets may belong to a same bypass branch, i.e., similar to the configuration of a liquid collector or liquid separator; or may belong to different bypass branches.
  • the falling film evaporator comprises a plurality of bypass branches, and each of the bypass branches may comprise at least one bypass inlet and/or bypass outlet.
  • the plurality of bypass outlets can also be arranged in an evenly spaced manner on the lower portion of the housing of the falling film evaporator. Thereby, the bypass refrigerant can be fed to the evaporator more evenly, thereby avoiding undue impact.
  • the bypass outlet may be arranged at the bottom of the housing of the falling film evaporator.
  • the refrigerant that enters the evaporator through the bypass outlet basically does not unduly affect the original refrigerant liquid level in the evaporator, making the entire bypass process more stable.
  • a pipe of the bypass branch has a circular and/or rectangular and/or trough-type cross-section, to adapt to different application scenarios and flow conditions.
  • the oil return branch 200 has a plurality of oil intake points 210.
  • the oil intake points 210 may belong to a same oil return branch, i.e., similar to the configuration of a liquid collector or liquid separator; or may belong to different oil return branches.
  • the refrigeration system comprises a plurality of oil return branches 200, and each of the oil return branches may comprise at least one oil intake point and/or oil return point.
  • a plurality of a plurality of oil intake points 210 can also be arranged in an evenly spaced manner on the lower portion of the housing 141 of the falling film evaporator. Thereby, the recovered lubricating oil can be sucked from the evaporator more evenly, thereby avoiding undue impact.
  • the oil intake point 210 may be arranged at the bottom of the housing 141 of the falling film evaporator.
  • the lubricating oil in the evaporator basically can all be recovered through the oil intake point 210, and the amount of lubricating oil accumulated in the evaporator will not be unduly large to affect the heat exchange performance of the evaporator and the lubrication performance of the compressor.
  • an ejector 230 may further be disposed on the oil return branch 200.
  • the ejector 230 has a first ejection inlet connected to the oil intake point 210, a second ejection inlet connected to an inlet side of the condenser 120, and an ejection outlet connected to the air inlet 110a of the compressor 110, to provides power for the oil return.
  • other oil return methods well known in the art can also be adopted according to different application scenarios.
