This utility model is an efficient energy saving refrigerating unit structure.
Description
Technical field:
The utility model relates to a kind of refrigeration unit structure.
Background technology:
In common refrigeration unit two stages of compression one-level circulating with choke, refrigerant liquid directly is throttled to evaporating pressure from condensing pressure, and liquid often utilizes the evaporation of refrigerant liquid in charge air cooler under the intermediate pressure to come cold before throttling, to improve the specific refrigerating effect of circulation, reduce the suction and discharge temperature of hiigh pressure stage simultaneously, reduced the power of hiigh pressure stage compressor.
Goal of the invention:
The purpose of this utility model is to provide a kind of efficient, energy-conservation refrigeration unit structure.
Summary of the invention:
For achieving the above object, the utility model is taked following design: this refrigeration unit structure, by condenser, in cold choke valve, intercooler, the economizer choke valve, expansion valve, evaporimeter, economizer, the low-pressure stage compressor, the hiigh pressure stage compressor is formed, the exhaust outlet of described low-pressure stage compressor is connected the air entry of described hiigh pressure stage compressor and the evaporation side gas vent of described intercooler respectively with pipeline, the inlet that the exhaust outlet of described hiigh pressure stage compressor is connected described condenser with pipeline, with the outlet of described condenser with pipeline connect respectively described intercooler the cold side liquid-inlet and described in an end of cold choke valve, the evaporation side liquid-inlet that the other end of cold choke valve in described is connected described intercooler with pipeline, the cold side subcooled liquid outlet of described intercooler is connected the cold side liquid inlet of described economizer and an end of described economizer choke valve respectively with pipeline, the evaporation side liquid inlet that the other end of described economizer choke valve is connected described economizer with pipeline, the economizer interface that the evaporation side gas vent of described economizer is connected described low-pressure stage compressor with pipeline, an end that the cold side subcooled liquid outlet of described economizer is connected described expansion valve with pipeline, the other end of described expansion valve is connected the inlet of described evaporimeter with pipeline, the outlet of described evaporimeter is connected the air entry of described low-pressure stage compressor with pipeline.
Because the utility model adopts above technical scheme, refrigerant superheat steam under the condensing pressure of hiigh pressure stage compressor discharge is the high pressure saturated liquid through condenser condenses, wherein cold choke valve is throttled to intermediate pressure in the sub-fraction warp, enters intercooler cooling another part highly pressurised liquid.The a part of highly pressurised liquid of this that is cooled is told a part again and is throttled to the economizer inlet pressure through the economizer choke valve, enters economizer and cools off remaining highly pressurised liquid.The steam that comes out from economizer is sucked from compressor economizer interface by the low-pressure stage compressor.The exhaust of low-pressure stage compressor and the vapor mixing of coming out from middle cooler enter the hiigh pressure stage compressor compresses together to condensing pressure.The above each parts is connected by pipeline, forms the complete refrigeration unit structure of a cover, offers the user, for providing low temperature cold source with cold unit.
In such refrigeration unit structure, the high pressure refrigerant liquid of last devaporation device throttling passed through in the past twice cold excessively, reached quite low temperature, so the specific refrigerating effect of circulation is significantly improved, and highly pressurised liquid can also be transported to the cold unit of far away, higher usefulness and can not gasify.The low-pressure stage compressor adopts the operating structure of band economizer, has equally also improved the refrigerating capacity and the refrigerating efficiency of low-pressure stage compressor.
Because the utility model adopts above technical scheme,, purpose of energy saving more efficient have more been reached than common two-stage refrigeration set structure.
Description of drawings:
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation
The specific embodiment:
As shown in Figure 1, this refrigeration unit structure of the utility model, by condenser 1, in cold choke valve 2, intercooler 3, economizer choke valve 4, expansion valve 5, evaporimeter 6, economizer 7, low-pressure stage compressor 8, hiigh pressure stage compressor 9 is formed, the exhaust outlet 23 usefulness pipelines of described low-pressure stage compressor 8 are connected the air entry 25 of described hiigh pressure stage compressor 9 and the evaporation side gas vent 14 of described intercooler 3 respectively, the inlet 10 that the exhaust outlet 26 usefulness pipelines of described hiigh pressure stage compressor 9 is connected described condenser 1, with the outlet 11 usefulness pipelines of described condenser 1 connect respectively described intercooler 3 cold side liquid-inlet 13 and described in an end of cold choke valve 2, the evaporation side liquid-inlet 12 that the other end of cold choke valve 2 in described is connected described intercooler 3 with pipeline, the cold side subcooled liquid outlet 15 usefulness pipelines of described intercooler 3 are connected the cold side liquid inlet 16 of described economizer 7 and an end of described economizer choke valve 4 respectively, the evaporation side liquid inlet 17 that the other end of described economizer choke valve 4 is connected described economizer 7 with pipeline, the economizer interface 24 that the evaporation side gas vent 19 usefulness pipelines of described economizer 7 is connected described low-pressure stage compressor 8, an end that the cold side subcooled liquid outlet 18 usefulness pipelines of described economizer 7 is connected described expansion valve 5, the other end of described expansion valve 5 is connected the inlet 20 of described evaporimeter 6 with pipeline, the outlet 21 usefulness pipelines of described evaporimeter 6 are connected the air entry 22 of described low-pressure stage compressor 8.
Because the utility model adopts above technical scheme, refrigerant superheat steam under the condensing pressure of hiigh pressure stage compressor 9 discharges is condensed into the high pressure saturated liquid through condenser 1, wherein cold choke valve 2 is throttled to intermediate pressure in the sub-fraction warp, enters intercooler 3 cooling another part highly pressurised liquids.The a part of highly pressurised liquid of this that is cooled is told a part again and is throttled to economizer 7 inlet pressures through economizer choke valve 4, enters the remaining highly pressurised liquid of economizer 7 coolings.The steam that comes out from economizer 7 is sucked from compressor economizer interface 24 by low-pressure stage compressor 8.The exhaust of low-pressure stage compressor 8 and the vapor mixing of coming out from middle cooler 3 enter hiigh pressure stage compressor 9 together and are compressed to condensing pressure.The above each parts is connected by pipeline, forms the complete refrigeration unit structure of a cover, offers the user, for providing low temperature cold source with cold unit.
Below only be an embodiment of the present utility model, any based on equivalents of the present utility model all within protection domain of the present utility model.
