As shown in Figure 3, flexible pipe transfer member 29 comprises stationary rack 32, gear 33, crank rocker mechanism 34 and stator ring 35.Stationary rack 32 is fixedly mounted on below ground.Gear 33 is meshed with stationary rack 32, can on stationary rack 32, come rollback moving, and gear 33 is arranged on the position near flexible pipe 27 arrival ends, and flexible pipe 27 is wrapped in the gear shaft (not shown) of gear 33 counterclockwise.Crank rocker mechanism 34 comprises fixed axis AC, swinging block 36, bent axle AB and bent axle BC.Fixed axis AC one end is fixed in gear shaft (not shown); Swinging block 36 is arranged on the other end of fixed axis AC, and can rotate around this end points; Bent axle AB one end and gear shaft (not shown) are hinged, and the edge of the other end and gear 33 is hinged; Bent axle BC is used for supporting flexible pipe 27, and one end and bent axle AB are hinged in the edge of gear 33, and the other end, through swinging block 36, can circle around swinging block 36.Stator ring 35 is arranged on the position near flexible pipe 27 ports of export, and flexible pipe 27 is wrapped on stator ring 35 clockwise.
While freezing in using 10 pairs of operating room (not shown)s of high-temperature air conditioner system, compressor 13 in refrigerating plant 11 is compressed into refrigerant gas the refrigerant gas of HTHP, the refrigerant gas of this HTHP enters the rear external heat release of condenser 14, forms the refrigerant liquid of HTHP.The refrigerant liquid of HTHP enters subcooler 15, with the cooling water heat exchange in cold emission water circle device 12, becomes the refrigerant liquid of cryogenic high pressure, is then temporarily stored in reservoir 16.The refrigerant liquid of cryogenic high pressure flows out from the first outlet of reservoir 16, the filter 17 that is dried is dry, and then entering heating power expansion valve 18, the refrigerant liquid of cryogenic high pressure expands and forms refrigerant air-liquid mixture in heating power expansion valve 18, then enters evaporimeter 19.In evaporimeter 19, refrigerant air-liquid mixture absorbs the heat in surrounding air, flashes to the refrigerant vapour of high temperature, thereby operating room (not shown) is freezed.The refrigerant vapour of high temperature is through ejector 21, enter after gas-liquid separator 22, the lubricated wet goods impurity being mingled with in refrigerant vapour is separated, then refrigerant vapour enters compressor 13, by compressor 13, be compressed into the refrigerant gas of HTHP, carry out kind of refrigeration cycle again, lubricated wet goods impurity is stayed in gas-liquid separator 22.Inlet pressure gauge 23 and delivery gauge 24, for detection of the pressure of the refrigerant gas of turnover compressor 13, reduce throughput when pressure is excessive, the safety of protection compressor 13.
When compressor exhaust temperature high pressure sets value, open assisted capillary 20, the refrigerant liquid of the part cryogenic high pressure in reservoir 16 enters assisted capillary 20, under the throttling action of assisted capillary 20, become the refrigerant liquid of low-temp low-pressure, the refrigerant liquid of this low-temp low-pressure enters ejector 21, high temperature refrigerant steam with evaporimeter 19 interior outflows, the refrigerant air-liquid mixture that formation temperature is lower, in gas-liquid separator 22, isolate gas-liquid two-phase, wherein refrigerant gas enters compressor 13, refrigerant liquid is stayed in gas-liquid separator 22.Therefore, high temperature refrigerant steam in evaporimeter 19 is lowered the temperature by the refrigerant liquid of low-temp low-pressure, the temperature that makes to flow into the refrigerant gas of compressor 13 reduces, the temperature of the refrigerant gas of discharging after compressor 13 compressions also correspondingly reduces, thereby can guarantee that compressor 13 more stably moves.
User can regularly discharge the refrigerant liquid and the lubricating oil that are retained in gas-liquid separator 22 at gas-liquid separator 22 bottom pipe layings, reuses.
In 11 pairs of operating room (not shown) refrigeration of refrigerating plant, the air chamber 30 of cold emission suspended ceiling 25 can isolated part solar radiant heat, adopt water pump 28 that the cooling water in header tank 26 is transported in the coil pipe 31 of cold emission suspended ceiling 25 by flexible pipe 27 simultaneously, cooling water absorbs solar radiant heat, avoids operating room (not shown) to be rapidly heated under the radiation of the sun.Then the cooling water in coil pipe 31 flows out through flexible pipe 27, and by subcooler 15, the heat at the refrigerant liquid of the interior absorption HTHP of subcooler 15, reduces the temperature of refrigerant liquid, thereby further reduce the cooling load of refrigerating plant 11.
When hoisting machinery moves to the direction away from header tank 26, make gear 33 be rotated counterclockwise line sending, flexible pipe 27 is sent, the gear shaft (not shown) of gear 33 drives crank rocker mechanism 34 motions, bent axle BC rotates around swinging block 36 under the drive of bent axle AB, by after line sending because the crooked sagging flexible pipe 27 of Action of Gravity Field supports.Meanwhile, stator ring 35 is turned clockwise, carry out take-up.When hoisting machinery moves to the direction away from header tank 26, make stator ring 35 be rotated counterclockwise line sending, gear 33 take-up that turns clockwise.Thereby cold emission suspended ceiling 25 can successfully be sent into cooling water by assurance flexible pipe 27.
The effect of embodiment and effect
The high-temperature air conditioner system 10 related according to the present embodiment, because reservoir 16 is provided with two ports of export, the refrigerant liquid of cryogenic high pressure flows out from first port of export, after device for drying and filtering 17 and heating power expansion valve 18, form refrigerant air-liquid mixture, then heat absorption in evaporimeter 19, freezes to operating room; When the excessive discharge temperature of compressor, can open assisted capillary 20, the refrigerant liquid throttling of part cryogenic high pressure is formed to the refrigerant liquid of low-temp low-pressure, and then in ejector 21, the high temperature refrigerant steam of evaporimeter 19 interior outflows is carried out to hydrojet refrigeration, therefore can effectively reduce intake air temperature and the delivery temperature of compressor 13, guarantee compressor 13 stable operations, can reduce the maintenance cost in later stage simultaneously.
In addition, because cold emission suspended ceiling 25 is installed at operating room top, the cooling water in air chamber 30 and coil pipe 31 can absorb most solar radiant heat, makes the temperature in operating room be unlikely to rise so high, therefore can reduce the cooling load of refrigerating plant 11, save cooling electric weight; Meanwhile, the cooling water in flexible pipe 27, through subcooler 15, absorbs the heat of the refrigerant liquid in subcooler 15, reduce the temperature of refrigerant liquid, thereby can improve coefficient of refrigerating performance, correspondingly can reduce the size of evaporimeter 19, be convenient to the installation of evaporimeter 19.
Therefore, this high-temperature air conditioner system 10 is applicable to the high-altitude application chamber of large scale hoisting machinery to freeze very much, not only can meet the cooling load of high-altitude application chamber, can also reduce power consumption and maintenance cost.
Certainly, the high-temperature air conditioner system that the utility model is related, is not merely defined in the structure described in above embodiment.These are only the basic explanation under the utility model design, and any equivalent transformation of doing according to the technical solution of the utility model all should belong to protection domain of the present utility model.
In the present embodiment, throttle ele-ment 20 is selected assisted capillary 20, can also select other members with throttling action, makes the pressure decreased of refrigerant liquid.The cross sectional dimensions of assisted capillary 20 is less, and therefore, refrigerant liquid, from assisted capillary 20 flows out, sprays in ejector 21, can make the rapid swelling heat absorption of refrigerant liquid, thereby effectively reduce the temperature of high temperature refrigerant steam.
