Embodiment
Below in conjunction with accompanying drawing, the utility model is done to describe further through embodiment.
Referring to Fig. 1, energy-saving rolling rotor type compressor comprises the housing 7 of cylindrical tube shape, and the upper end of housing 7 is connecting upper shell cover 12, and outlet pipe 13 is housed on the upper shell cover 12, and the lower end of housing 7 is connecting lower cover 14.Be axially arranged with bent axle 1 in the housing 7; The motor of being made up of rotor 10 and stator 9 is installed on one side of bent axle 1; Upper cylinder cover 2, piston 4 and following cylinder cap 5 are installed on the opposite side of bent axle 1 successively, and the outer cover of piston 4 is equipped with cylinder 6, is provided with sucking pipe 16 with cylinder 6 corresponding shell 7 one sides.Cylinder 6 is a ring-type, and a side periphery is provided with projection; Offer perforation intakeport 6.1 and blade groove radially on the projection one side cylinder respectively; Blade 15 is housed in the blade groove; The inner of blade 15 closely contacts with the excircle of piston 4; Blade 15 is separated into air aspiration cavity and exhaust cavity with cylinder 6, and wherein the air aspiration cavity side is connected with intakeport 6.1, is provided with a relief opening 6.4 near leaf position on the inner circumference of the cylinder 6 of exhaust cavity side.Upper cylinder cover 2, cylinder 6 and following cylinder cap 5 are fixed together through a plurality of bolts 3 that axially are uniformly distributed with.Baffler 11 is installed on the upper cylinder cover 2; Offer heat exchange groove 6.2 on the periphery of the axial end of the cylinder 6 corresponding with upper cylinder cover 2; Heat exchange groove 6.2 is the big semicircle arcuation; One end of heat exchange groove 6.2 is being communicated with intakeport 6.1, and the other end is connected with drainage tube 8, and the other end of drainage tube 8 extends housing 7 outsides along the projection place of cylinder 6.
The compressor of the utility model is introduced heat exchange groove 6.2 with the refrigeration system condenser ends part liquid level below part of liquid container (or in the system) high pressure low temperature refrigeration agent throttling step-down after becoming liquid through drainage tube 8, and countercylinder 6 cools off.This part refrigeration agent heat absorption evaporation imports the cylinder 6 inner compression processes of participating in after be communicated with the heat exchange groove 6.2 of the intakeport 6.1 of cylinder.Stoped of the heat transmission of the high-temperature exhaust air of compressor inner casing 6 outsides to gas in the jar owing to being provided with of heat exchange groove 6.2 is effective; Obvious when the drainage refrigeration agent is flowed through in the heat exchange groove 6.2 on the axial end of cylinder 6 to the gas in the jar cooling effect, force cylinder inner refrigerant compression process convergence isothermal.Reverse heat exchange is carried out by the air-breathing refrigeration agent that carries out cyclic process to exhaust in drainage refrigeration agent in the heat exchange groove 6.2 of cylinder 6 and cylinder 6 inside; Import the intakeport 6.1 of cylinder 6 behind the drainage refrigeration agent absorption heat; Kept the pressure reduction at drainage tube 8 two ends, the drainage circulation is able to trouble-free operation; Heat exchange groove 6.2 ends are communicated with intakeport 6.1 vertical angles of cylinder, and with intakeport 6.1 small vertical interference are only arranged on heat exchange groove 6.2 depth directions, can not destroy the inspiratory flow pulsation, cause the inspiratory flow loss.
When using the compressor of this structure cylinder to allocate refrigeration system into, only need set up one section drainage system (capillary tube controlled) like caliber.This section drainage throttling arrangement connects the drainage tube interface that the refrigeration system condenser ends liquid level below part of liquid container (or in the system) and compressor housing pick out.The drainage part refrigeration agent that gets into hermetic compressor through the liquid refrigerant after the throttling cooling is not contributed system's refrigerating capacity, but has participated in the gas compression processes in the cylinder, the part wasted work that needs to consume compressor.Through the control to drainage throttling arrangement flow, caliber, the compression wasted work of drainage refrigeration agent is wanted much less with respect to the saving merit of the nearly isothermal compression process of refrigeration agent.Therefore, through the layout of drainage refrigerant circulation loop, can effectively promote the performance of compressor and refrigeration system.Simultaneously, because approximate isothermal compression realization process, compressor exhaust temperature also significantly reduces, and is that existing rolling rotor type compressor and a whole set of refrigeration system are carried out the feasible program that efficiency promotes.
