Description

A kind of novel energy-conserving refrigeration system
One, technical field
The utility model relates to refrigeration system.
Two, background technology
Under the constant situation of condensation temperature, the high more refrigerating efficiency of evaporating temperature is high more in refrigeration system.In order to improve the ability and the efficient of system under the low evaporating temperature, conventional way be with one independently in the part cold-producing medium of warm system supply with another independently cryogenic system to carry out liquid cold excessively.Though improved refrigerating efficiency, but middle temperature system and cryogenic system are equipped with a cover system separately, and need to carry out exterior line between middle temperature system and the cryogenic system and be connected, if two system's present position distances are distant, exterior line is longer, can cause more loss of refrigeration capacity in transmission course, longer pipe road and insulation material can increase extra equipment investment expense, cost height.
Three, summary of the invention
The purpose of this utility model is to overcome above-mentioned not enough problem, and a kind of novel energy-conserving refrigeration system is provided, and simple in structure, cost is low, the refrigerating efficiency height.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of novel energy-conserving refrigeration system, comprise cryogenic system and middle temperature system, in warm system and cryogenic system compressor exhaust pipe be connected the high-pressure section that oil eliminator, condenser and reservoir constitute jointly, in the warm system reservoir that directly links to each other, liquid is crossed cold back pipeline and is connected the supply cryogenic system, the suction end of the gas outlet pipe Lu Lianzhong temperature compressor in the heat exchanger after the liquid evaporation.
The condensator outlet of described refrigeration system connects the reservoir import, the reservoir outlet divides two road pipelines, first via pipeline connects the heat exchanger import, the second road pipeline is communicated with heat exchanger through expansion valve 6 ', the heat exchanger exhaust outlet through in be communicated with behind the wet liquid/gas separator in warm compressor, in the blast pipe of warm compressor be communicated with oil eliminator, oil eliminator is communicated with condenser, the cold liquid outlet of heat exchanger is communicated with the cryogenic vaporizer import through expansion valve, the cryogenic vaporizer exhaust outlet is communicated with cryogenic compressor behind gas-liquid separator, the cryogenic compressor exhaust outlet is communicated with oil eliminator 2.
The outlet of described reservoir also is provided with the Third Road pipeline, and Third Road is through expansion valve 6 ' ' be communicated with after the throttling in warm evaporator, middle temperature evaporator outlet through in warm compressor in the connection behind the wet liquid/gas separator.
Warm compressor and cryogenic compressor are helical-lobe compressor, piston compressor or screw compressor in described.
Warm compressor and cryogenic compressor are unit compressor or compressor bank in parallel in described.
Word described in the utility model " middle temperature " is comparatively speaking with " low temperature ", and selected low evaporating temperature is defined as low temperature, and evaporating temperature is higher than the low-temperature evaporation temperature and is defined as middle temperature.
The utility model is simple in structure, by the evaporating temperature of part cold-producing medium in the raising system, reach and improve entire system cold and purpose of energy saving, by the assembling section functional part with the simplification system and save cost.Promptly include warm system at cryogenic system, cryogenic system and the middle temperature system common high voltage part parts that include greatly dwindle pipeline and connect distance, reduce the loss of refrigeration capacity in the transmission course, thereby reduce system cost and simplify connecting line.The energy saving of system effect mainly is because warm system work under high evaporation temperature (high refrigerating efficiency) in the kind of refrigeration cycle, low-temp. portion separatory body heat content in the absorption system, make the liquid of cryogenic system cold excessively, increase the enthalpy difference in the cryogenic system evaporimeter, and the minimizing expansion-loss, thereby improve the cryogenic system refrigerating capacity.
Four, description of drawings
Fig. 1 is common refrigeration unit system principle schematic diagram.
Fig. 2 is that tradition is crossed the cooling system principle schematic.
Fig. 3 is the utility model system principle schematic diagram.
Five, the specific embodiment
Be example with compressor bank in parallel below, the present invention is described in further detail in conjunction with the accompanying drawings:
Novel energy-conserving refrigeration system as shown in Figure 3, compare with traditional energy-conserving refrigeration system (as Fig. 2), basic refrigeration principle identical (as shown in Figure 1), but saved parts oil eliminator 2 ', condenser 3 ', reservoir 4 ', the condensator outlet pipeline connects the reservoir import, the reservoir outlet divides the three-way connection (pipe) road, first via pipeline connects the heat exchanger import, the second road pipeline is communicated with heat exchanger through expansion valve 6 ', the heat exchanger exhaust outlet through in be communicated with behind the wet liquid/gas separator in warm compressor, in the blast pipe of warm compressor be communicated with oil eliminator, oil eliminator is communicated with condenser, the cold liquid outlet of heat exchanger is communicated with the cryogenic vaporizer import through expansion valve, the cryogenic vaporizer exhaust outlet is communicated with cryogenic compressor behind gas-liquid separator, the cryogenic compressor exhaust outlet is communicated with oil eliminator 2, and Third Road is through expansion valve 6 " be communicated with after the throttling in warm evaporimeter 7 ' import, middle temperature evaporator outlet through in warm compressor in the connection behind the wet liquid/gas separator.Used compressor can be helical-lobe compressor, piston compressor or screw compressor unit compressor or compressor bank in parallel in the system.
During work, at first the liquid from condenser 3 enters reservoir 4, and the highly pressurised liquid that comes out from reservoir 4 is divided into three the tunnel, and first via liquid is cold excessively through heat exchanger 5; Enter heat exchanger 5 evaporations after the 6 ' throttling of the second road liquid process expansion valve, Third Road is through expansion valve 6 " enter after the throttling in warm evaporimeter 7 ' (Third Road is Fig. 3 frame of broken lines part; if actual conditions do not need in temperature refrigeration or the compressor 1 ' ability selected for use can only to satisfy cryogenic system liquid colod-application excessively; this part can be omitted); cross the cryogenic vaporizer 7 that liquid after cold enters the demand end after through expansion valve 6 throttlings, the cryogenic vaporizer exhaust outlet enters cryogenic compressor 1 after being communicated with gas-liquid separator 8.Enter gas-liquid separator 8 ' through the gas after heat exchanger 5 evaporations, warm compressor 1 ' compression during gas behind the process separating liquid enters, the exhaust that compiles compressor 1 through the gas behind the compressor 1 ' together enters oil eliminator 2, is condensed into liquid through entering condenser 3 behind the oil eliminator 2.The cold-producing medium that is used to evaporate in the heat exchanger 5 also can be from the subcooled liquid behind the heat exchanger 5.
