Description
Technical field
The utility model belongs to the Compressor Technology field, relates in particular to a kind of worst hot case compressor.
Background technique
In the family expenses air-conditioning technical field, to different use climatic environment maximum temperatures, air conditioner is divided into T1; T2, three kinds of operating mode types of T3 (referring to the definition of GB/T7725-2004 " room air conditioner "), the varying environment working condition that the air conditioner of three kinds of climate types is corresponding; Wherein, The T3 operating mode is the megathermal climate type, uses climatic environment (maximum temperature) can reach 52 ℃, and service condition is the most abominable.Work under the T3 rugged environment when air-conditioner refrigerating system, its refrigeration system is easy to produce high pressure, and compressor overcurrent, overheated, overload protective device tripping promptly appear in can not start shooting operation or the start just of many air conditioners, i.e. compressor " jumping machine " phenomenon.In case compressor is jumped machine, just can resume operation automatically more than wanting half an hour at least, and can jump machine once more very soon, form vicious circle, also reduced the two-phase section of effective heat exchange simultaneously, cause the decline of refrigerating capacity and Energy Efficiency Ratio.To T3 operating mode area service condition, the compressor that uses on the air-conditioning at present often adopts the way that improves the air condition compressor insulation class or adopts the housing cooling of overcooled liquid gunite with cooler compressor.The compressor that sprays cooling method is close with T1 operating mode compressor because of the insulating material temperature classification requirement of motor; Far below the T3 operating mode compressor that improves the insulation class method; Thereby cost is low relatively; Its principle is in the air conditioner running, before Compressor Discharge Pressure does not reach the maximum protection value, the liquid refrigerant of condensation is ejected in the cylinder of compressor at the condensator outlet place through returning the liquid capillary tube; Utilize the latent heat of vaporization of refrigeration agent to come cooling compressor, thereby a similar T1 operating mode compressor operating environment is provided.Overcooled liquid jet-type T3 operating mode compressor air-conditioning device refrigeration system schematic diagram is as shown in Figure 1, and system is made up of compressor 1, four-way valve 7, outdoor heat exchanger 8, main capillary tube 9, indoor heat exchanger 6, time liquid capillary tube 5.Wherein return liquid capillary tube 5 one ends and connect compressor 1, the other end is connected between main capillary tube 9 and the outdoor heat exchanger 8.Referring to Fig. 2, time liquid capillary tube 5 is generally all long, about 2M.; The coiled circle also takes up space very much, and the caliber that returns liquid capillary tube 5 is less; But need be connected with compressor, the welding position easy of crack is in market, the Middle East; Air conditioner returns when under the excess load condition, moving has feedback, the client improvement existing structure that all claims when the situation of fracture appears in the liquid capillary tube.
The model utility content
For addressing the above problem; The utility model purpose aims to provide a kind of worst hot case compressor; Configuration pressure reducing protection device in compressor; Cancel back the liquid capillary tube, when avoiding welding back the liquid capillary tube weldering stifled, prevent effectively that air conditioner from returning when under loading condiction, move that rupturing appears in the liquid capillary tube and the situation that causes air conditioner to work.
For realizing that above-mentioned purpose adopts following technological scheme: the worst hot case compressor; Be arranged in the refrigeration system of air conditioner, on the fuselage of compressor, hole for back flow be set, in hole for back flow, be provided with the injection orifice union; Said injection orifice union comprises valve seat, valve pocket, injection throttling core; Said valve seat is fixed in the hole for back flow, and said injection throttling core sealing is arranged in the valve pocket, and said injection throttling in-core is provided with throttle orifice.
Said valve pocket connects transition tube at the opening end of compressor fuselage outer side.
Rounded corner is established in the end of said injection throttling core, and the sealing cone of said rounded corner and valve pocket is suitable.
Also be provided with o-ring groove on the cylindrical wall of the end of said injection throttling core.
The built-in seal ring of said o-ring groove.
The end face of said injection throttling core is provided with the hexagon ring that caves in.
The beneficial effect of the utility model is:
The worst hot case compressor of the utility model is not provided with back the liquid capillary tube, reduces the restriction of compressor to the circuit design space.Compressor liquid return hole internal diameter is bigger, avoids welding stifled risk, returns the hidden danger of quality that fracture appears in the liquid capillary tube when effectively preventing air conditioner under loading condiction, to move.

Embodiment
For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that practical implementation described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in Fig. 3-6, the utility model is provided with the injection orifice union on the fuselage of worst hot case compressor 1, makes compressor under worst hot case, have the function of spraying cooling.Spraying orifice union is installed in the hole for back flow of compressor; The injection orifice union comprises: valve seat 4, valve pocket, injection throttling core 2; Be provided with screw thread in the valve pocket; The corresponding end that is provided with retaining thread 22, injection throttling core of outer wall of spraying throttling core 2 is a rounded corner 21, and is suitable with the sealing cone of valve pocket.Be provided with inner hexagonal hole 26 in the end face of the other end of injection throttling core, on the cylindrical wall of this end, also be provided with o-ring groove 24, built-in seal ring 25.Opening end welding transition pipe 3 at the compressor outside, valve seat.During installation, can insert hexagon ring 26, spray throttling core 2 through retaining thread 22 and valve pocket screwed through interior hexagonal.When tightening, spray throttling core rounded corner 21 and be close to the sealing cone of valve pocket, make and spray throttling core 2 and valve seat 4 bore seal, the refrigeration agent that the assurance system sprays is throttle orifice 23 circulations from spraying throttling core 2 centers only.Seal ring 25 is enclosed within on the o-ring groove 24, and seal ring 25 forms interference fit with valve pocket, further sealing.
When the air conditioner refrigerating operaton, flow to the high pressure that sprays throttling core 2 and export from outdoor heat exchanger, low pressure is from compresser cylinder.Because it is very little to spray the throttle diameter of throttling core, makes circulating resistance bigger, under the general operating mode, the refrigerant flow of the injection throttling core 2 of flowing through is all smaller, almost nil.When air conditioner moves under rugged environment; Its condensation load is very big, and condensing pressure is higher, and the pressure reduction that sprays throttling core 2 two ends increases; Strengthened the flow of circulation injection throttling core 2 refrigeration agents; The liquid refrigerant of part condensation is ejected in the cylinder of compressor, and the latent heat of vaporization of refrigeration agent comes cooling compressor, thereby causes similar T1 operating mode compressor operating environment.Effectively protected the reliability operation of compressor.
