Abstract
An automobile air conditioner parent-subsidiary refrigerating cycle system (shown in the figure) with a diffusing pipe comprises a main compressor 1, a condenser 2, the diffusing pipe 3, a throttling valve 4, an evaporator 5, a first electromagnetic valve 6, a capillary pipe 7, a refrigerator evaporator 8, a coolant 9, an insulating layer 10 and a second electromagnetic valve 11, wherein a high-pressure liquid refrigerant from the condenser 2 becomes a jet flow in the diffusing pipe 3, and generates a low pressure, lower than the pressure of the gaseous refrigerant from the refrigerator evaporator 8, in the middle of the diffusing pipe 3, so as to absorb the refrigerant at the outlet of the refrigerator evaporator 8 into a spray pipe, supply power for a subsystem (refrigerator cold accumulation system), and ensure that the refrigerant in the subsystem can flow to realize refrigerating cycle. The refrigerant at the rear half part of the diffusing pipe is diffused, so that the pressure of the refrigerant at the outlet of the diffusing pipe is lower than the pressure of the refrigerant at the inlet of the diffusing pipe but higher than the pressure of the refrigerant at the inlet of the evaporator; then the refrigerant enters into the evaporator after being throttled.
Description
One, technical field:
The present invention utilizes the effect of diffuser pipe to realize the lifting of evaporator of refrigerator outlet pressure a kind of relating on the basis of automobile air-conditioning refrigeration circulation (mother system), completes the kind of refrigeration cycle of refrigerator system (subsystem).
Two, background technology:
Mostly air conditioning for automobiles is simple refrigeration, only reduces air themperature in car, there is no the refrigeration and cold accumulation equipment that temperature is lower, orthodox car refrigerator adopts compressor to drive refrigerator refrigeration system circulation conventionally, electric quantity consumption is large, and another kind of semiconductor freezer efficiency is low, and power consumption is large.Two kinds of refrigerator of vehicles all can not come heat in car to extraneous heat extraction, increase air conditioning for automobiles thermic load.
Three, summary of the invention:
In the present invention, mother system is for air-conditioning in car, and subsystem follows that the operation of mother system is freezed, cold-storage, provide low temperature cold source for stored article.The present invention overcomes the deficiency that prior art exists, and designs a kind of energy of mother system that utilizes and by the effect of diffuser pipe, realizes the boost in pressure of evaporator outlet refrigerant vapour in subsystem (refrigerator system), done subsystem kind of refrigeration cycle.This circulation does not need to use electric power, not to heat extraction in car.
Air conditioning for automobiles primary and secondary cooling cycle system with diffuser pipe comprises: (referring to figure) main compressor 1, condenser 2, diffuser pipe 3, choke valve 4, evaporimeter 5, the first magnetic valve 6, capillary 7, evaporator of refrigerator 8, agent for storage of coldness 9, heat-insulation layer 10, the second magnetic valve 11.Main compressor 1 gas outlet connects condenser 2 imports, and condenser 2 outlets are divided into two-way, and a road connects diffuser pipe 3 imports, one tunnel connects the first magnetic valve 6 imports, diffuser pipe 3 outlets connect choke valve 4 imports, and choke valve 4 outlets connect evaporimeter 5 imports, and evaporator outlet connects main compressor gas returning port.The first magnetic valve 6 outlets connect capillary 7 imports, capillary 7 outlet connection evaporator of refrigerator 8 imports, and evaporator of refrigerator outlet connects the second magnetic valve 11 imports, and the second magnetic valve 11 outlets connect the middle import of diffuser pipe.
Four, accompanying drawing explanation:
Accompanying drawing is the air conditioning for automobiles primary and secondary cooling cycle system schematic diagram the present invention relates to diffuser pipe.
Five, specific embodiments:
First, by system schematic, relevant device is installed, is made every effort to save space, conservation, guarantees that pipeline is unimpeded, reduces pipe range, reduces the pressure loss, in the light of actual conditions configures corresponding diffuser pipe and size of refrigerator.Then start automobile, open air conditioning for automobiles, main compressor 1 brings into operation, low-temp low-pressure gaseous refrigerant is compressed into high temperature and high pressure gaseous refrigerant in main press, high temperature and high pressure gaseous refrigerant is cooled into as high pressure liquid refrigerant in condenser 2, high pressure liquid refrigerant is divided into two-way thereafter, the first via is kind of refrigeration cycle mother system, first via cold-producing medium enters diffuser pipe 3 imports, due to long-pending from import to middle nozzle section, diminish gradually, in diffuser pipe 3, form jet, refrigerant pressure reduces, wherein diffuser pipe 3 middle sectional areas are minimum, refrigerant pressure reduces minimum, when pressure decreased is in lower than subsystem during evaporator of refrigerator 8 outlet pressure, the cold-producing medium of evaporator of refrigerator outlet is inhaled in diffuser pipe 3.Owing to increasing gradually from diffuser pipe 3 middles pipeline section is backward long-pending, the cold-producing medium of the subsystem being inhaled into and the cold-producing medium in mother system be diffusion together, to jet pipe 3 outlets, finish diffusion, the pressure of jet pipe 3 outlets is also greater than the pressure of A/C evaporator, after the throttling action of choke valve 4, low-temperature low-pressure refrigerant enters in evaporimeter 5, becomes low-temp low-pressure gaseous state and enter main compressor 1 in evaporimeter 5 after heat absorption, realizes circulation; The second tunnel is kind of refrigeration cycle subsystem, the second road cold-producing medium is first by magnetic valve 6, then by the reducing pressure by regulating flow effect of capillary 7, high pressure liquid refrigerant is become after low-pressure low-temperature gas-liquid binary states cold-producing medium, enter in evaporator of refrigerator 8 agent for storage of coldness 9 is absorbed heat, under the insulation effect of heat-insulation layer 10, make temperature obtain the maintenance of certain hour.Low-pressure low-temperature gaseous refrigerant after heat absorption is under the effect of diffuser pipe 3, be inhaled into pipeline middle, converge with first via cold-producing medium jet, for preventing, because first via cold-producing medium refluxes and enters the second road refrigerant-cycle systems higher than subsystem evaporator of refrigerator 8 outlet pressures at diffuser pipe 3 middle pressure, the second magnetic valve 11 being installed before entering diffuser pipe 3 middles.After primary and secondary system refrigerant is mixed, through at choke valve 4 reducing pressure by regulating flows and after evaporimeter 5 lets cool, enter main compressor 1, realize kind of refrigeration cycle.Diffuser pipe 3 middle pressure are during lower than evaporator of refrigerator exit refrigerant pressure, and the second magnetic valve 11 is opened, otherwise the second magnetic valve 11 cuts out.When vehicle interior temperature reaches requirement, or main compressor quits work, and diffuser pipe 3 is not at jet, and the first magnetic valve 6 and the second magnetic valve 11 are closed simultaneously.
